I'm currently using Vb.net in connection with the Unity Container model. But I can't get it to work.
My code is always failing in the Factory.
unity.config:
<unity>
<containers>
<container>
<types>
<type type="TestApplication.Interfaces.IBuilder, TestApplication.Interfaces" mapTo="TestApplication.Classes.Builder, TestApplication.Classes">
<lifetime type="singleton" />
</type>
</types>
</container>
</containers>
</unity>
I'm using a custom config source referenced in my App.config file.
The app.config looks like this:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<section name="unity" type="Microsoft.Practices.Unity.Configuration.UnityConfigurationSection, Microsoft.Practices.Unity.Configuration" />
</configSections>
<unity configSource="unity.config" />
</configuration>
My Factory.vb looks like this:
Imports Microsoft.Practices.Unity
Imports Microsoft.Practices.Unity.Configuration
Imports System.Configuration
Public NotInheritable Class Factory
Private Shared registeredTypes As New Dictionary(Of Type, Object)
Public Shared Function GetInstance(Of T)(Optional asSingleton As Boolean = False) As T
Using container As UnityContainer = Factory.GetConfiguredUnityContainer()
Dim instance = container.Resolve(Of T)()
If (asSingleton = True And Not Factory.registeredTypes.ContainsKey(GetType(T))) Then
Factory.Register(Of T)(instance)
End If
Return instance
End Using
End Function
Private Shared Function GetConfiguredUnityContainer() As UnityContainer
Dim container As New UnityContainer
container.LoadConfiguration()
For Each item In registeredTypes
container.RegisterInstance(item.Key, item.Value)
Next
Return container
End Function
Private Shared Sub Register(Of T)(instance As T)
registeredTypes(GetType(T)) = instance
End Sub
End Class
The Factory fails at the line:
container.LoadConfiguration() in the GetConfiguredUnityContainer method.
A first chance exception of type System.Configuration.ConfigurationsErrorsException occured in System.Configuration.dll
I do have references to the mapped assembly. TestApplication.Classes also to the TestApplication.Interfaces
The interface is named IBuilder.vb and the class is named Builder.vb
References in the project:
Microsoft.Practices.Unity
Microsoft.Practices.Unity.Configuration
PresentationCore
PresentationFramework
System.Configuration
Please suggest me any chances, I'd be happy.
Greets.
So, after I checked some things over the weekend, I came to the conclusion that vb.net doesn't support an external unity configSource.
You could parse the config file with an xml parser and read each value. But I'm too lazy for that.
I edited my:
app.Config like that:
Inserted the container from the unity.config to my app.config
Code:
<configuration>
<configSections>
<section name="unity" type="Microsoft.Practices.Unity.Configuration.UnityConfigurationSection, Microsoft.Practices.Unity.Configuration"/>
</configSections>
<unity>
<container>
<register type="TestApplication.Interfaces.IBuilder, TestApplication.Interfaces" mapTo="TestApplication.Classes.Builder, TestApplication.Classes" />
</container>
</unity>
I registered the type/s inside the App.config, after that I can read the container with my Factory, and can work with the unity container.

It sounds like you are using the wrong url. Tomcat generally has a folder called webapps for applications that are deployed on that server. To figure out the configuration, in Eclipse, open up the Server tab, find your Tomcat server and double-click on it.
It should bring up a properties pane with two tabs at the bottom Overview and Modules. Click on Modules and you should see the path to your app. For me, it's in the form of: /webapps/<project name>
Your full url would be localhost:8080/webapps/<project name>/anystringhere.do since you map anything in your app (localhost:8080/webapps/<project name>/) that ends in .do to the action servlet.

The host server is a Windows server 2008 R2 64-bit with IIS 7.5 and the latest updates for OS and .NET 4 framework installed on it.
The funny thing is that when I deployed before I did not get this error until I updated the server with windows updates. Another thing that I have noted is that if I set the type of publish to debug the application works without any problems while it does not with release publish type.
I did also try to deploy to local folder on my dev machine and then copy the content to the host server, but got the same end results.

The root cause of the problem was that when web.conf transformation was performed on appSettings for custom keys, they overwrote all other keys with the same value of the first custom key. So a simple change on the -> solved the problem.
This can be seen in the stack trace where the application crashes when this function in MVC System.Web.Mvc.ViewContext.GetClientValidationEnabled is called to check if clientSideValidation is enabled or not. More info can be found in this thread http://forums.asp.net/t/1924833.aspx/1?Format+exception+on+Html+BeginForm+String+was+not+recognized+as+a+valid+boolean
In vs 2010, on right clicking and updating the service reference pointing to my xamlx workflow service project, it throws an error (written in raw html) stating that :
XamlObjectWriterException : 'Cannot create unknown type [...]'
[...] pointing out a message variable of my project.
My workflow is xamlx hosted with WorkflowServiceHost class.
It seems to be due to the SendResponse message. Message type uses [DataContract] and [DataMember], and 'Parameters' ha been chosen in the content UI.
Can't find out what exactly is messing in my message type. Maybe it is something in the build properties of my wkf project ...
Any help is very welcome.
Here is the html sent back :

Metadata contains a reference that cannot be resolved: 'http://localhost:8008/WfDerogationCreation.xamlx'.
The server did not provide a meaningful reply; this might be caused by a contract mismatch, a premature session shutdown or an internal server error.
If the service is defined in the current solution, try building the solution and adding the service reference again.
I eventually solved this problem like this :
In the couple of ReceiveResponse / SendReply activities.
1/ Delete SendReply.
2/ Recreate SendReply by right clicking on the ReceiveResponse activity and reset properties like on the deleted one.
Xamlx service reference then uploaded quite well ...
Found that error message was quite inappropriate written in raw html, my screen wasn't big enough to read all of it. Anyway, thank you for your help.
This is the Xaml stack's way of telling you that it doesn't know about CompanyName.WorkflowSecurity.Derogation.Messages. What you need to do is figure out why it doesn't know about this type.
The assembly name sure looks strange though "CompanyName.WorkflowSecurity}DerogRequest" notice the '}'? Is that a typo?
Check the XAMLX file at Line number '4' and line position '8'
Say I have a struts.properties file with a defined value uploads.directory . How can I access that value from an Actioncontext programatically?
You can use getText("some.property.name") which return you the property value
http://struts.apache.org/maven/struts2-core/apidocs/com/opensymphony/xwork2/ActionSupport.html
Create ActionSupport Object and by using getText() method of ActionSupport class.
ActionSupport actionSupport = new ActionSupport();
actionSupport.getText("foo.bar");
Create a resources folder under src.
In the struts.xml file add a constant e.g., <constant name="struts.custom.i18n.resources" value="global"></constant>
Here global is the name of properties file.
Now you will be able to use the properties in the entire application.

global.properties
action.welcome.username=waqar
In action class
System.out.println(getText("action.welcome.username"));
You need to put the my.properties file or my_locale.propeties file in the package that houses your action class.
You need to put the values in properties files other than struts.properties for examples ApplicationResources.properties or my.properties which needs to be in the classpath. struts.properties file is used to load struts specific properties for example struts.i18n.encoding=UTF-8 or struts.devMode = false etc.
The thing you need to do in struts.properties after you create the properties file for your customized messages is you have to add the following property in struts.properties file
struts.custom.i18n.resources=ApplicationResources
If you have more than one custom message property files then you need to add them by separating with comma for example:
struts.custom.i18n.resources=ApplicationResources,my
Then in your action classes you can access the property values by using getText('propertyName')
you can get value from message resource file like this:
public class MyAction extends ActionSupport {
public String getUserDetails() {
if("First Name".equals(getText("label.firstName"))) {
System.out.println("In if block");
}
}
}
you can also get more information, how to get values from .properties files in java class or jsp files.
for JSP:
<s:text name="label.firstName" />
and
<s:property value="getText('label.age')" />
for more information you can go through this link:
