JavaSerializer - Error serializing object class

[Stefan Lorenz]

Hi,

with Glassfish4 we get a lot of Exceptions when a page gets serialized.

org.apache.wicket.serialize.java.JavaSerializer - Error serializing object class
..
org.apache.wicket.core.util.objects.checker.CheckingObjectOutputStream$ObjectCheckException:
 The object type is not Serializable!
A problem occurred while checking object with type: 
com.sun.ejb.containers.EJBLocalObjectInvocationHandlerDelegate
Field hierarchy is:
..
..
private final org.jboss.weld.ejb.api.SessionObjectReference 
org.jboss.weld.bean.proxy.EnterpriseBeanProxyMethodHandler.reference 
[class=org.glassfish.weld.ejb.SessionObjectReferenceImpl]
private 
java.lang.Object org.glassfish.weld.ejb.SessionObjectReferenceImpl.ejbRef 
[class=com.sun.proxy.$Proxy202]
  protected 
java.lang.reflect.InvocationHandler java.lang.reflect.Proxy.h 
[class=com.sun.ejb.containers.EJBLocalObjectInvocationHandlerDelegate] - 
field that is causing the problem


Any idea where this is coming from or what's causing this?

Regards,
Stefan

you can only have Serializable classes stored in the page
you can have DTO or ID stored if it is impossible

Hi,

This is a well known issue with CDI+EJB. It has been discussed few times
here and other forums.
CDI injects non-Serializable objects for EJB beans.
A workaround is to use a delegate CDI bean to lookup the EJBs. I.e. instead
of @Inject-ing EJBs in Wicket components inject a scoped CDI bean that
injects the EJBs in itself.
So the usage in Wicket would be:

public class MyComponent extends ... {
  @Inject MyCDIBean cdiBean;
  ...

  cdiBean.getEjb().doSomething();
  ...
}
