I'm trying to develop a small Stripes project that allows the user to uoload files, the basic implementation of the ActionBean looks like so:
public class UploadActionBean extends BaseActionBean{
private FileBean fileBean;
private final String fileUpload="/WEB-INF/jsp/file-upload.jsp";
public void setFileBean(FileBean fileBean){
this.fileBean=fileBean;
}
public FileBean getFileBean(){
return this.fileBean;
}
#DefaultHandler
public Resolution goToFile(){
return new ForwardResolution(fileUpload);
}
public Resolution upload() throws IOException{
System.out.println(fileBean.getFileName());
fileBean.getContentType();
fileBean.getSize();
fileBean.save(new File("/Users/enricoiorio/Desktop"));
return new ForwardResolution(fileUpload);
}
}
As i said is very simple, the jsp is like this, also very simple:
<s:form beanclass="stripesbook.action.UploadActionBean" enctype="multipart-form/data">
<s:file name="fileBean"/>
<s:submit name="upload" value="upload"/>
The app seems to deploy correctly, the app starts with no problem but as soon as i click on upload i get the following exception:
net.sourceforge.stripes.exception.StripesRuntimeException: Could not construct a MultipartWrapper for the current request.
which arrives from a nullPointerException:
at net.sourceforge.stripes.controller.multipart.DefaultMultipartWrapperFactory.wrap(DefaultMultipartWrapperFactory.java:151)
I understand that i have to use the wrap() method of the DefaultMultipartWrapperFactory class, but how?
I'm struggling trying to find a documentation that explains that but no results, any advise?
Seems like you're simply missing Commons FileUpload. Try adding it to your classpath and see if it works.
I had got the same problem.
Got resolved by adding init param in stripes Filters.
<init-param>
<param-name>MultipartWrapper.Class</param-name>
<param-value>net.sourceforge.stripes.controller.multipart.CommonsMultipartWrapper</param-value>
</init-param>

I have some custom logging in my plugin and want to include the contents of my tracingService in my custom logging (which is called within a catch block, before the plugin finishes).
I cant seem to access the content of tracingService. I wonder if it is accessible at all?
I tried tracingService.ToString() just incase the devs had provided a useful overload, alas as expected I get name of the class "Microsoft.Crm.Sandbox.SandboxTracingService".
Obviously Dynamics CRM makes use of the tracingService content towards the end of the pipeline if it needs to.
Anybody have any ideas on this?
Kind Regards,
Gary
The tracing service does not provide access to the trace text during execution but that can be overcome by creating your own implementation of ITracingService. Note, you cannot get any text that was written to the trace log prior to the Execute method of your plugin being called - meaning if you have multiple plugins firing you won't get their trace output in the plugin that throws the exception.
public class CrmTracing : ITracingService
{
ITracingService _tracingService;
StringBuilder _internalTrace;
public CrmTracing(ITracingService tracingService)
{
_tracingService = tracingService;
_internalTrace = new StringBuilder();
}
public void Trace(string format, params object[] args)
{
if (_tracingService != null) _tracingService.Trace(format, args);
_internalTrace.AppendFormat(format, args).AppendLine();
}
public string GetTraceBuffer()
{
return _internalTrace.ToString();
}
}
Just instantiate it in your plugin passing in the CRM provided ITracingService. Since it is the same interface it works the same if you pass it to other classes and methods.
public class MyPlugin : IPlugin
{
public void Execute(IServiceProvider serviceProvider)
{
var tracingService = new CrmTracing((ITracingService)serviceProvider.GetService(typeof(ITracingService)));
tracingService.Trace("Works same as always.");
var trace = tracingService.GetTraceBuffer();
}
}
To get the traceInfo string from traceService at runtime I used debugger to interrogate the tracingService contents.
So the trace string is accessible from these expressions...
for Plugins
((Microsoft.Crm.Extensibility.PipelineTracingService)(tracingService)).TraceInfo
for CWA
((Microsoft.Crm.Workflow.WorkflowTracingService)(tracingService)).TraceInfo
You can drill into the tracing service by debugging and extract the expression.
However, at design time neither of these expressions seem to be accessible from any of the standard CRM 2011 SDK dlls... so not sure if its possible as yet.
Error like:The view 'LoginRegister' or its master was not found or no view engine supports the searched locations. The following locations were searched:
~/Views/MyAccount/LoginRegister.aspx
~/Views/MyAccount/LoginRegister.ascx
~/Views/Shared/LoginRegister.aspx
~/Views/Shared/LoginRegister.ascx
~/Views/MyAccount/LoginRegister.cshtml
~/Views/MyAccount/LoginRegister.vbhtml
~/Views/Shared/LoginRegister.cshtml
~/Views/Shared/LoginRegister.vbhtml
Actually my page view page is ~/Views/home/LoginRegister.cshtml so what i do
and my RouteConfig is
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "MyAccount", action = "LoginRegister", id = UrlParameter.Optional }
);
}
}
Be careful if your model type is String because the second parameter of View(string, string) is masterName, not model. You may need to call the overload with object(model) as the second parameter:
Not correct :
protected ActionResult ShowMessageResult(string msg)
{
return View("Message",msg);
}
Correct :
protected ActionResult ShowMessageResult(string msg)
{
return View("Message",(object)msg);
}
OR (provided by bradlis7):
protected ActionResult ShowMessageResult(string msg)
{
return View("Message",model:msg);
}
Problem:
Your View cannot be found in default locations.
Explanation:
Views should be in the same folder named as the Controller or in the Shared folder.
Solution:
Either move your View to the MyAccount folder or create a HomeController.
Alternatives:
If you don't want to move your View or create a new Controller you can check at this link.
In Microsoft ASP.net MVC, the routing engine, which is used to parse incoming and outgoing URL Combinations, is designed with the idea of Convention over Configuration. What this means is that if you follow the Convention (rules) that the routing engine uses, you don't have to change the Configuration.
The routing engine for ASP.net MVC does not serve web pages (.cshtml). It provides a way for a URL to be handled by a Class in your code, which can render text/html to the output stream, or parse and serve the .cshtml files in a consistent manner using Convention.
The Convention which is used for routing is to match a Controller to a Class with a name similar to ControllerNameController i.e. controller="MyAccount" means find class named MyAccountController. Next comes the action, which is mapped to a function within the Controller Class, which usually returns an ActionResult. i.e. action="LoginRegister" will look for a function public ActionResult LoginRegister(){} in the controller's class. This function may return a View() which would be by Convention named LoginRegister.cshtml and would be stored in the /Views/MyAccount/ folder.
To summarize, you would have the following code:
/Controllers/MyAccountController.cs:
public class MyAccountController : Controller
{
public ActionResult LoginRegister()
{
return View();
}
}
/Views/MyAccount/LoginRegister.cshtml: Your view file.
In your LoginRegister action when returning the view, do below, i know this can be done in mvc 5, im not sure if in mvc 4 also.
public ActionResult Index()
{
return View("~/Views/home/LoginRegister.cshtml");
}
Check the build action of your view (.cshtml file) It should be set to content. In some cases, I have seen that the build action was set to None (by mistake) and this particular view was not deploy on the target machine even though you see that view present in visual studio project file under valid folder
This could be a permissions issue.
I had the same issue recently. As a test, I created a simple hello.html page. When I tried loading it, I got an error message regarding permissions. Once I fixed the permissions issue in the root web folder, both the html page and the MVC rendering issues were resolved.
Check whether the View (.ASPX File) that you have created is having the same name as mentioned in the Controller. For e.g:
public ActionResult GetView()
{
return View("MyView");
}
In this case, the aspx file should be having the name MyView.aspx instead of GetView.aspx
I got this error because I renamed my View (and POST action).
Finally I found that I forgot to rename BOTH GET and POST actions to new name.
Solution : Rename both GET and POST actions to match the View name.
If the problem happens intermittently in production, it could be due to an action method getting interrupted. For example, during a POST operation involving a large file upload, the user closes the browser window before the upload completes. In this case, the action method may throw a null reference exception resulting from a null model or view object. A solution would be to wrap the method body in a try/catch and return null. Like this:
[HttpPost]
public ActionResult Post(...)
{
try
{
...
}
catch (NullReferenceException ex) // could happen if POST is interrupted
{
// perhaps log a warning here
return null;
}
return View(model);
}
I had this same issue.
I had copied a view "Movie" and renamed it "Customer" accordingly.
I also did the same with the models and the controllers.
The resolution was this...I rename the Customer View to Customer1 and
just created a new view and called it Customer....I then just copied
the Customer1 code into Customer.
This worked.
I would love to know the real cause of the problem.
UPDATE
Just for grins....I went back and replicated all the renaming scenario again...and did not get any errors.
I came across this error due to the improper closing of the statement,
#using (Html.BeginForm("DeleteSelected", "Employee", FormMethod.Post))
{
} //This curly bracket needed to be closed at the end.
In Index.cshtml view file.I didn't close the statement at the end of the program. instead, I ended up closing improperly and ran into this error.
I was sure there isn't a need of checking Controller ActionMethod code because I have returned the Controller method properly to the View. So It has to be the view that's not responding and met with similar Error.
If you've checked all the things from the above answers (which are common mistakes) and you're sure that your view is at the location in the exceptions, then you may need to restart Visual Studio.
:(
In my case, I needed to use RedirectToAction to solve the problem.
[HttpGet]
[ControleDeAcessoAuthorize("Report/ExportToPDF")]
public ActionResult ExportToPDF(int id, string month, string output)
{
try
{
// Validate
if (output != "PDF")
{
throw new Exception("Invalid output.");
}
else
{
...// code to generate report in PDF format
}
}
catch (Exception ex)
{
return RedirectToAction("Error");
}
}
[ControleDeAcessoAuthorize("Report/Error")]
public ActionResult Error()
{
return View();
}
I ran into this a while ago and it drove me crazy because it turned out to be simple. So within my View I was using a grid control that obtained data for the grid via an http request. Once the middle tier completed my request and returned the dataset, I received the same error. Turns out my return statement was 'return View(dataset);' instead of 'return Json(dataset);
I couldn't find any solution to this problem, until I found out the files didn't exist!
This took me a long time to figure out, because the Solution Explorer shows the files!
But when I click on Index.cshtml I get this error:
So that was the reason for this error to show. I hope this answer helps somebody.
I've written an Xtext-based plugin for some language. I'm now interested in creating a new independent view (as a separate plugin, though it requires my first plugin), which will interact with the currently-active DSL document - and specifically, interact with the model Xtext parsed (I think it's called the Ecore model?). How do I approach this?
I saw I can get an instance of XtextEditor if I do something like this when initializing my view:
getSite().getPage().addPartListener(new MyListener());
And then, in MyListener, override partActivated and partInputChanged to get an IWorkbenchPartReference, which is a reference to the XtextEditor. But what do I do from here? Is this even the right approach to this problem? Should I instead use some notification functionality from the Xtext side?
Found it out! First, you need an actual document:
IXtextDocument doc = editor.getDocument();
Then, if you want to access the model:
doc.modify(new IUnitOfWork.Void<XtextResource>() { // Can also use just IUnitOfWork
#Override public void process(XtextResource state) throws Exception {
...
}
});
And if you want to get live updates whenever it changes:
doc.addModelListener(new IXtextModelListener() {
#Override public void modelChanged(XtextResource resource) {
for (EObject model : resource.getContent()) {
...
}
}
});
I feel a Little stuck right now. First I used nuget to
install-package Bootstrap.less
as well as
install-package dotless
Then, as shown in Rick Andersons Blogpost about bundling and minification in asp.net mvc, I created a LessTransform-Class. I set up 2 nearly empty .less files and created a new bundle packaging them...
var lessBundle = new Bundle("~/MyLess").IncludeDirectory("~/Content/MyLess", "*.less", true);
lessBundle.Transforms.Add(new LessTransformer());
lessBundle.Transforms.Add(new CssMinify());
bundles.Add(lessBundle);
That worked well. Then I added a new StyleBundle to the main bootstrap.less file (which basically uses #import to include all the other .less files that bootstrap.less ships)...
bundles.Add(new StyleBundle("~/Bootstrap").Include("~/Content/Bootstrap/less/bootstrap.less"));
and a ScriptBundle to the bootstrap JavaScripts...
bundles.Add(new ScriptBundle("~/bundles/Bootstrap").Include("~/Scripts/bootstrap/js/bootstrap-*"));
to include all shipped bootstrap-*.js files and TADAA everything worked fine. The CSS got compiled including all imported JavaScript files were properly loaded.
But ... all that only worked for development mode with
<compilation debug="true" targetFramework="4.5"/>
As soon as I disable debug to see if the bundling into one file and the minification works properly I encounter the Problem.
The bundling process seems to fail to import all those .less files imported into bootstrap.less
/* Minification failed. Returning unminified contents.

having a look at the minified bootstrap.javascript bundle also boggles me. in dev there was no Problem after loading the page, now after the bootstrap.javascript was bundled and minified in Google the JavaScript console states
Uncaught TypeError: Cannot read property 'Constructor' of undefined
I have had a look at several Topics that seemed closely related to my Problem, and I tried a few things, but so far without success.
Many thanks in advance to anyone who could shed some light into my Situation and who would point out what I am missing or doing wrong. Best regards, Ingo
If you want to use bootstrap as less-files and in addition want to stop worrying about bundling and minification on your development machine as well as on your production machine, you might consider using the following approach.
Note: you don't need all this if you only play around with Less-Files while DEBUGging is enabled; But as soon as you want your application to go live on a production server like Windows Azure, and still want to just modify your less files without having to take care about the bundling and minification procedures... well... then this approach will work
So in order to solve the problem I felt a little stuck in, I had to approach the problem differently and had to modify (see Modification 2 further down the post) the "BundleSource" I thought I'd like to have.
SO DONT FORGET TO READ THE 2nd Modification/Warning close to the bottom of this answer!
MODIFICATION 1)
So the first and bigger part of the job is to get the bundling of the bootstrap-less files working. In order to do that I took the liberty to fork a piece of code I found in the web that (if you only need one less-file bundle) itself solves my problem... unless you might want to use or be able to use multiple less-bundles with several base directories... So that is where I actually found the approach that helped me a lot ...
... wherefore I award many thanks to Kristof Claes for his Blog-Entry "Using ASP.NET bundling and minification with LESS files" which I accidently and gladly stumbled over.
Like me he tried to use the LessMinify.cs that Scott Hanselman was showing in his speeches to work with 1 LESS-file instead of just bundling every single file in 1 directory full of LESS-files.
But he had to extend the whole bundling procedure slightly as he shows in his Blog-Entry. That way the solution he proposes can bundle 1 less file that uses imports to load other less files. But as he statically implements the path that is added to the source directory in which to find the less files... whichever less bundle you define has to pick a less file in the same directory...
That is where I took the liberty to extend his solution a bit further. I created a file LessBundling.cs with the following content:
using dotless.Core.configuration;
using dotless.Core.Input;
using MvcApplication2.Utils;
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Runtime.CompilerServices;
using System.Web;
using System.Web.Hosting;
using System.Web.Optimization;
namespace MvcApplication2.Extensions
{
// create Less-Minifier (use Type to define source directory of less files [see below at BootstrapFileReader])
public class LessMinify<TFileReader> : CssMinify
where TFileReader : IFileReader
{
public LessMinify() {}
public override void Process(BundleContext context, BundleResponse response)
{
var config = new DotlessConfiguration()
{
MinifyOutput = true,
ImportAllFilesAsLess = true,
CacheEnabled = false,
LessSource = typeof(TFileReader)
};
response.Content = dotless.Core.Less.Parse(response.Content, config);
base.Process(context, response);
}
}
// create a LessStyleBundler to allow initializing LessBundle with a single less file that uses imports
public class LessStyleBundle<TFileReader> : Bundle
where TFileReader : IFileReader
{
public LessStyleBundle(string virtualPath)
: base(virtualPath, new LessMinify<TFileReader>()) {}
public LessStyleBundle(string virtualPath, string cdnPath)
: base(virtualPath, cdnPath, new LessMinify<TFileReader>()) { }
}
// create abstract VirtualFileReader from dotless-IFileReader as a Base for localized
internal abstract class VirtualFileReader : IFileReader
{
public byte[] GetBinaryFileContents(string fileName)
{
fileName = GetFullPath(fileName);
return File.ReadAllBytes(fileName);
}
public string GetFileContents(string fileName)
{
fileName = GetFullPath(fileName);
return File.ReadAllText(fileName);
}
public bool DoesFileExist(string fileName)
{
fileName = GetFullPath(fileName);
return File.Exists(fileName);
}
public string GetFullPath(string path)
{
return HostingEnvironment.MapPath(SourceDirectory + path);
}
public abstract string SourceDirectory {get;}
// implement to return Path to location of less files
// e. g. return "~/Content/bootstrap/less/";
}
// create BootstrapFileReader overwriting the Path where to find the Bootstrap-Less-Files
internal sealed class BootstrapFileReader : VirtualFileReader
{
public override string SourceDirectory
{
get { return "~/Content/bootstrap/less/"; }
}
}
}
So what does this actually do?
LessMinify extends the CssMinify class and therefore brings everything needed to minify css files
The important difference to "usual" bundling is that you create a new Dotless-Configuration with the LessSource defined as typeof(TFileReader) ...
By using <TFileReader> you can define a class that will contain the source directory in which the bundler/minifier will look for the less files to be taken into account
LessStyleBundle extends Bundle and therefore brings everything needed to bundle the files
In this class I again use TFileReader as this is where the LessMinify(er) will be instantiated
VirtualFileReader implements IFileReader which is a dotless interface defining all methods required to parse less files and give information where to find files to be imported
In order to extend Kristof's solution to the problem I added the abstract property SourceDirectory... requiring me to also make the VirtualFileReader abstract class
Now with that setup you can create as many LessFileReaders as you want. You just have to extend the abstract VirtualFileReader as can be seen in
BootstrapFileReader extends VirtualFileReader
The only purpose of the BootstrapFileReader is to have a property-getter for the SourceDirectory in which the bundler/minifier will find the less files that are to be imported
Well in my case Bootstraps Less-Files where lying in ~/Content/bootstrap/less which should be the default location if you install the "twitter.bootstrap.less"-nugget.
If you'd have another directory in your application, which contained a less file which again has multiple imports you just create a new class extending VirtualFileReader and define the property-getter for the SourceDirectory to return the corresponding path
If you then want to use this Bundling method to actually bundle and minify less files in a production environment you just add the LessStyleBundle-instantion to the BundlerConfig.cs:
bundles.Add(new LessStyleBundle<BootstrapFileReader>("~/bundles/BootstrapCSS")
.Include("~/Content/bootstrap/less/bootstrap.less"));
and of course your _Layout.cshtml should also be aware of the readily prepared bundle
#Styles.Render("~/bundles/BootstrapCSS")
MODIFICATION 2)
now the minor Modification which I also had to add to get this working
In my first attempt to bundle bootstrap.less I used this
bundles.Add(new LessStyleBundle<BootstrapFileReader>("~/Content/BootstrapCSS")
.Include("~/Content/bootstrap/less/bootstrap.less"));
I thought I would use Content in the routes for CSS/Less and Bundles in the routes for Javascript.
But that does not work out of the box. ASP.net doesnt permit the creation of a Bundle that starts with ~/Content. You will get a 403 authorization failure. Therefore the easiest solution to that is to use ~/bundles instead:
bundles.Add(new LessStyleBundle<BootstrapFileReader>("~/bundles/BootstrapCSS")
.Include("~/Content/bootstrap/less/bootstrap.less"));
As there aren't many real solutions to this problem I hope this will help at least some of you if you plan to integrate twitter bootstrap into your asp.net mvc4 application.
best regards,
Ingo
I've modified Ingo workaround to get rid of custom classes for each directory.
Also, I've added proper exception output (because otherwise all exceptions was silent and you just got empty less file in case of error).
public class LessTransform : IItemTransform
{
[ThreadStatic]
internal static string CurrentParsedFileDirectory;
public string Process (string includedVirtualPath, string input)
{
CurrentParsedFileDirectory = Path.GetDirectoryName (includedVirtualPath);
var config = new DotlessConfiguration
{
MinifyOutput = false,
CacheEnabled = false,
MapPathsToWeb = true,
ImportAllFilesAsLess = true,
LessSource = typeof (VirtualFileReader),
Logger = typeof (ThrowExceptionLogger)
};
return Less.Parse (input, config);
}
}
internal class VirtualFileReader : IFileReader
{
public bool UseCacheDependencies
{
get { return false; }
}
public byte[] GetBinaryFileContents (string fileName)
{
return File.ReadAllBytes (GetFullPath (fileName));
}
public string GetFileContents (string fileName)
{
return File.ReadAllText (GetFullPath (fileName));
}
public bool DoesFileExist (string fileName)
{
return File.Exists (GetFullPath (fileName));
}
public string GetFullPath (string path)
{
if (string.IsNullOrEmpty (path))
return string.Empty;
return HostingEnvironment.MapPath (path[0] != '~' && path[0] != '/'
? Path.Combine (LessTransform.CurrentParsedFileDirectory, path)
: path);
}
}
public class ThrowExceptionLogger : Logger
{
public ThrowExceptionLogger (LogLevel level) : base (level)
{
}
protected override void Log (string message)
{
if (string.IsNullOrEmpty (message))
return;
if (message.Length > 100)
message = message.Substring (0, 100) + "...";
throw new LessTransformException (message);
}
}
[Serializable]
public sealed class LessTransformException : Exception
{
public LessTransformException (string message) : base (message)
{
}
}
Usage:
bundles.Add (new StyleBundle ("~/styles-bundle/common")
.Include ("~/content/bootstrap/bootstrap.less", new LessTransform ()));
I was having the same issue today, I found a work around but I'd like a better solution as well. I was also trying to use dotless and a custom transform like what you have.
Workaround:
Pre-build event:
"$(SolutionDir)packages\dotless.1.3.1.0\tool\dotless.compiler.exe" "$(ProjectDir)Content\less\bootstrap.less"
That will create a bootstrap.css file which you can then include as regular CSS instead of LESS.
This solution isn't ideal, as you'd have to update the build event each time you update dotless, and having the bundle handle it is cleaner as well.
I really, really recommend installing WebEssentials 2012 instead.
It will generate a css-file AND a minified css-file from your .less and you can reference the css instead. It will automatically update the css everytime you make a change to your .less so there is no need to remember any pre-build steps or anything...
When installing WebEssentials you'll also get other sweet features like preview of CoffeeScript, TypeScript and LESS. JSHint, automatic minification and lots and lots more "goodies"!
I just wanted to try a tutorial (https://ccp.cloudera.com/display/DOC/Hadoop+Tutorial) program WordCount V.2 (bottom of the page) in which they are using the following method to set up some basic variables for the programm:
public void configure(JobConf job) {
...
}
However I'm trying to use the new Hadoop API and this method does not seem to exist anymore? Can anyone tell me what the equivalent way of doing something like this in the new API is?
Also how can I access my Configuration during runtime? Do I simply call:
Job.getConfiguration();
You can override the setup method in your Mapper/Reducer, this will behave like configure.
The signature looks as follows:
#Override
protected void setup(Context context) throws IOException,
InterruptedException {
There you get a Context object, where you can call:
Configuration conf = context.getConfiguration();
map and cleanup, both have these context objects, so you can get your Configuration anytime.
