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.

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

2009-10-12 Thread Dariusz 

I don't know for sure if it's required or not, but what about your
table annotation?

@Entity
@Table(name = "user")
public class User implements IsSerializable{
   ...

using a JPA annotated class in a RPC call yelds IncompatibleRemoteServiceException

2009-10-11 Thread Alexandru Ioan 

I came across this strage problem...

I have this entity bean

@Entity
public class User implements IsSerializable{

private static final long serialVersionUID = 1L;

@Id
@GeneratedValue
private Long id;

@Column
private String name;

@Column
private String password;

//... getters and setters...
}

If I send this bean over an RPC call, I get an

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
