Validation in GWT 2.4 How To?

[objectuser]

Is there a how-to on setting this up?  I actually have it working but am wondering about a couple things like:

1. Do I have to have the two source archives in WEB-INF/lib, or do they just need to be in the compile path?
   
2. Is there a recommended way of setting it up with GIN?
   

Thanks.

I used this post to set it up.  

The shared RequestFactory interfaces and their server domain counterparts are only required during the compilation.

I may be further from understanding that I thought, but I'm talking about Bean Validation (javax.validation).  Is that post still applicable?

[Y2i]

Oh, the post is about request factory validation.  Before 2.4 the errors were caught at GWT compile time (or debug time in debugging mode), now they are caught at javac compile time.  Sorry, I misunderstood the question.

Im also having problems regarding client side bean validation using annotations in 2.4. Anyone have any info in this?

I have it "working", just not sure if it's the best way.

What are your problems?  Maybe I can help.

I Also have an issue with Validation.jar file.

 

I can't build my application with GWT 2.4. but I can build the same application with GWT 2.0. Here is list of software I use.

 

GWT 2.4

Spring 2.5.4

Hibernate 3.7

 

This is my 'workaround'. I remove the validation-api-1.0.0.GA.jar from my eclipse plugin directory. (C:\MyProgram\eclipse\plugins\com.google.gwt.eclipse.sdkbundle_2.4.0.r36v201108301710\gwt-2.4.0). Then I can build my application. I need better 'working' solution of it.

 

Please refer to the error message attached below. Thanks for your help!

I think your issue is just a deployment issue.  I don't think you have GWT 2.4 properly installed in your web app.

[Bing]

Thanks for your reply, objectUser! Yes. The error message does come from deployment.

 

I installed GWT 2.4 SDK and GWT Desinger through eclipse plugin. Here are the sites I used and what I selected to install.

GWT-2.4 SDK - http://dl.google.com/eclipse/plugin/3.6

(I selected Google Plugin for Eclipse(required), GWT Designer for GPE(recommended), and SDKs)

GWT-Designer - http://dl.google.com/eclipse/inst/d2gwt/latest/3.6

(GWT Designer and WindowBuilder Engine(required))

 

I didn't have any error message during installation. Can you tell what I did wrong to cause this Validation issue? Thanks for your help!

[objectuser]

I just think you need to make sure that the libs in WEB-INF/lib are up to date, including the validation jars (the API and sources and the Hibernate implementation and sources).

[objectuser]

Replying to my own post ... it looks to me that you don't need the sources jars in your WEB-INF/lib, just your compile path for the GWT compile phase.  Not having them in WEB-INF/lib could be important if you're using GAE.

If anyone's interested, here's how I did it:
