GWT with JPA

I'm trying to build database application using GWT 1.5.3. I use JPA annotations with my objects. It seems in hosted mode GWT's RPC works fine. But when I try to compile my app using GWT-compiler I get errors like: "The import javax.persistence cannot be resolved", "Entity cannot be resolved to a type". toplink-essentials.jar is already included in my project path. What settings else do I need to solve this problem?

Solution

  • Ok, I've found what I was missing. I needed to include jpa-annotations-source.jar in my GWT-compiler path in myapp-compile.cmd script (or in ant build file). By the way can anyone tell me the origin of this jpa-annotations-source.jar file?
