Re: EAR application with war (GWT) and JPA

you need to make sure you validate the beans using the JPA validation before GWT will use them. also when you deal with more complex enterprise scenerios like yours, GWT's server communication and factories for the the beans SUCK!. In fact they break often and do not handle proper json seriliazation of more complex structures. We had to implement our own RESTful interface using the more basic RPC service approach. We then pipe the json structures into an external java servlet project which has all fo our DTO and DAO. The gets around not habving to deal with the really frustrating bean validation that requires, yes requires you to include the source code.

I have a maven project consisting of a parent project with 3 modules. 

1. Modul is a GWT webapp. 

2. Modul is a jar module using session beans and Hibernate. called server module

3. Modules is module that builds the ear file ( maven-ear-plugin ) 

In the webapp I created a GWT gui than can create records in the database. 

It does that with an injected session bean from the server module. 

Second I can search for records in the database. 

This is also done vie the session bean. 

And here is the problem. 

I have a hibernate entity bean in the server module. Product

When searching the session bean returns a list of product beans to the GWT server implementation. 

The webapp knows about the product bean cause maven dependencies. 

I would like this list of products to be listed in the gui. 

But when compiling : 

No source code is available for type com.xx.yy.server.model.Product

Sure enough, the product bean in a maven dependency. 

I can of cause create a new product DTO in the webapp an convert the product bean to this product DTO... but that sounds stupid. 

Anyone got a good solution for this.
