In my web application (Java EE), I would like to print a pdf file generated on the server side
on the fly in the client side without opening it. The files could be one or many. Is this possible?
I think it is not possible, except if you require clients to install a special application first.
Not just Java EE, it would be the same with any server-side technology.
You either need an additional Java library or to pass it to native code. There is a blog article with some suggestions at http://www.jpedal.org/PDFblog/2010/01/printing-pdf-files-from-java/

My searches have turned up nothing concrete. My extension uses Google's file picker to allow the user to browse their sheets and choose a desired file to write some data to, which manifest v3 breaks because of some GAPI limitations. Unless I've missed something obvious, there does not seem to be a simple workaround or method for this to migrate to v3 -- it just seems to be disallowed.
I'm not asking if there's a way to do something that they intend to not be possible (even though I doubt such a thing would exist with Google) but I'm optimistically hoping that maybe there is some hacky/annoying workaround that still fits within their rules. If I absolutely have to just allow them to set a sheet URL manually I will...I'm just trying to avoid it.
Any tips or suggestions would be appreciated.
You may have to test it yourself to make sure there are no weird behaviors, but Google has some recommendations regarding this in their migration guide:
In Manifest V3, all of your extension's logic must be included in the extension. You can no longer load and execute a remotely hosted file. A number of alternative approaches are available, depending on your use case and the reason for remote hosting. Here are approaches to consider:
Configuration-driven features and logic
In this approach, your extension loads a remote configuration (for example a JSON file) at runtime and caches the configuration locally. The extension then uses this cached configuration to decide which features to enable.
Externalize logic with a remote service
Consider migrating application logic from the extension to a remote web service that your extension can call. (Essentially a form of message passing.) This provides you the ability to keep code private and change the code on demand while avoiding the extra overhead of resubmitting to the Chrome Web Store.
Bundle third-party libraries
If you are using a popular framework like React or Bootstrap, you can download the minified files, add them to your project and import them locally.
For your case, option #3 seems like the easiest. Looking at the Google Picker API documentation it only uses two relatively small script files, https://apis.google.com/js/api.js and https://accounts.google.com/gsi/client. You could try to bundle these in your Chrome extension and call the methods locally.
I have a "proof of concept" piece of work that crosses over into some unfamiliar territory. I have some experience on J2EE technologies. I'm tasked with connecting an EFTPOS machine to an web application. I am planning to use applet to interact with dll. dll will be running on the client side.
I need to interact with one dll from web application. Please provide me any guidance on this, as I am new to it. I tried interacting with dll from standalone java program, but not able to connect from web application. Any sample codes will be very helpful for me.
Yes that is perfectly possible with an applet. I "connected" an electronice signing device before and it was working very well. Depening on what kind of .dll we are talking about here you need to do the following things:
1.) Create a java access layer / interface for your dll, so that you are able to call the dll functions from java. Depending what kind of dll we are talking about there are several possibilities. The base technology is JNI which is however quite cumbersome to use but luckily there are much more convienient ways out there:
use JNA (if it is a C dll)
use Jacob (if it is a COM component)
use bridj (if it is a c++ dll. You may try swig but haven't used that, so can't tell)
2.) Put your dll inside a jar file and distribute it alongside your applet. How this works is quite nicely described in the jacob project which provides an example for that. You can find it in the source package under jacob-1.17_src.zip\jacob-1.17\samples\com\jacob\samples\applet The example describes the JNLP way to access a native library which will work above java version 1.6.0_10. If you have to use a lower version for some reason, it is also possible but is slightly more tricky...
3.) One more side note: Since the latest available java version (1.7.0_51 or 1.6.0_71) due to security, some rules have been added or tightened for java applets. Now you have to sign your applet with an official certificate and set the right attributes/properties in the manifest, jnlp files. But this has been discussed in great detail here so just search for it. I would probably use a slightly older version for development and if that is working, figuring out how to make it work in the latest java version...
4.) Regarding the interaction part there are also several possibilities. Your Java Applet can call jscript methods from the website it is running in (or also the other way around) or the applet directly communicates with your server. You have all possibilities on that front...
I want to first of all thank everyone for the help I got here in the past. After completing my web application using Html, PHP, jQuery, Javascript, CSS, MYSQL, I realized I don’t want a website. In the end, for security, I prefer knowing who will be accessing my application. Having said that, I want to use most of the work I already did for my website. I understand I can use PHP with AIR and MySQL. I read that many would recommend using SQLite, but my problem is that I will constantly be updating the database. I also read there are some security issues using MYSQL and AIR.
Question 1, if I took the "necessary" security precautions within PHP which connects to MYSQL, would that be ok or is there soething else I should be aware of wit AIR ?
Question 2 if I really need to use SQLite, is there a way to connect to Mysql so that I may update the database.
I'm open to suggestions if there is a third party software that will covert my project to a desktop application with connectivity to MYSQL I also have a third party flash embedded.
Thanks
Make it mandatory to sign in to the website to use it. Will that not be sufficient to know who is accessing your application?
PHP is a server side language. Adobe AIR is desktop application framework. I am not sure that converting a PHP-MySQL application to an Adobe AIR application will be a trivial task.
You can take the distributed application route though by doing the client side in AIR and writing the web services in PHP/MySQL. And if you want a distributed database too, it will get lot more complicated.
You can build a rest api with php and integrate it with adobe air applications via http no need js for this. Just use actionscript with urlloader urlstream.
If you need an offline db you can use sqlite and sync with Mysql via php.
You'll have to forget PHP and use javascript and SQL sintax to do it. You can check this pretty guide from adobe to do so http://help.adobe.com/en_US/air/html/dev/air_htmldevguide.pdf
It won't be easy ;P
Is there any SDK available to convert MS word and Excel files to PDF ? I wan to do it on Web Server at run time. Im using VS 2010, .Net Framewrok 4.0
I looked into MS interop assembly but then this artical pushed me back http://support.microsoft.com/kb/257757
is there any thirdparty tool/SDK/Service available that will do that at runtime?
Check out iText, there is a Java and C# library however I think the .NET library is not free. http://www.itextpdf.com/
If you are after perfect conversion then there is no real solution available / viable other than somehow involving Office. Plain MS-Interop is a nightmare and very unreliable, but there are good third party solutions available.
Give the Muhimbi PDF Converter Services a look. It installs in your environment as a scalable and robust Windows Service and has specifically been designed for use from server based applications such as ASP.NET.
It comes with a friendly web services based interface that allows it to be used from most modern environments such as Java and .NET. It supports all common as well as some not so common file formats. Watermarking and PDF Security is included as well. If you have SharePoint in your environment then a SharePoint optimised version is available as well.
Disclaimer, I have worked on this product so the usual disclaimers apply. Having said that, it works great.
You can use the Save as function which is already available in Microsoft.Office.Interop
doc.SaveAs(ref FileName, Microsoft.Office.Interop.Word.WdSaveFormat.wdFormatPDF);
I'm looking for the equivalent of a URL shortening service such as http://bit.ly/ for an internal deployment in our organisation. Anyone know of any open source projects (especially Java ones) or commercial products which I can install internally rather than using an external service?
Thanks!
Shorty : http://get-shorty.com/
But there's several other url shortener .... most of them are in PHP/Mysql.
Don't know if a Java one exist.

tells you the core basics of how to achieve the concept with PHP and Htaccess building up from there I can say would solely be on your own. However not all to hard a concept in general to build off of if you know php/mysql. That said your not likely to find anything directly built in JavaScript however using this with JavaScript again wouldn't be all that hard a concept. I say your not likely to find one JS based as you need some type of server-side script to communicate with a DB somewhere, where you have all your short URL identifiers, and JavaScript to my knowledge doesn't support directly at least database connectivity. You can go through any means of AJAX to communicate with a server-side script to then do what you want with the JavaScript though.
