Re: GWT with JPA

Thanks Juan for your quick reply, I think I did not explain my problem
enough detailled so I try it again: My project compiles right so I
don't think it is a class-path problem in the common way: Refering to
http://code.google.com/intl/de-DE/webtoolkit/doc/latest/DevGuideServerCommunication.html#DevGuideSerializableTypes
I have to assure the following:
# The class is annotated with a JPA javax.persistence.Entity
annotation. -> I did this in my Entity object

for example:
@Entity
public class Member implements Serializable{

private static final long serialVersionUID = -8354006649751924339L;

public Long id;
}

# The fully-qualified class name is listed as one of the values of the
rpc.enhancedClasses configuration property in a .gwt.xml module file
that is part of the application. -> I think this is my problem. I
don't know how to put the class into my .gwt.xml file and I cannot
find any description how to do this, I only found some comments, that
the annotation can not be read by the client gwt code (which is clear
to me), but how can I put them into the gwt.xml file?

Thanks for your help
