Re: using a JPA annotated class in a RPC call yelds IncompatibleRemoteServiceException

See this related material:

https://projects.azoth.eu/jreactor/wiki/jdoAndGWT

You JDO impl actually enhances Java byte code which then cannot be serialized by GWT.

You should see in your JDO impl documentation if there is some way to bypass this kind of bytecode enhancement. The best place would be your JDO impl mailing list to continue the discussion.

I came across this strage problem...

If I remove the @Id and @GeneratedValue annotations, all runs fine...

Hello,

sorry, I forgot to mention. I use google web application, datanucleus as JPA implementation. If I use Hibernate, it doesn't reproduce.
Also, debugging through the GWT sources, I came across this:

in com.google.gwt.user.server.rpc.impl.SerializabilityUtil.generateSerializationSignature
when iterating over the bean's fields, an
protected java.lang.Object[] com.dinc.bandmplace.client.model.User.jdoDetachedState
appears.

thx
