serialization problem with spring
Hi
i have a serialization problem with spring
My CreatePage class looks like:-
public class CreatePage extends WebPage{
@SpringBean
AccountManager accountManager;
}
as i am using @SpringBean , it should handle creating a serializable proxy
for me BUT
i got the following exception
ERROR - JavaSerializer - Error serializing object class
com.app.view.account.CreatePage [object=[Page class =
com.app.view.account.CreatePage, id = 1, render count = 1]]
java.io.NotSerializableException:

Posted by Bruno Borges <br...@gmail.com>.
What version of Wicket are you using?
On older versions you must declare your field as transient.
Newer versions don't required this anymore.

Re: serialization problem with spring
Posted by Dan Retzlaff <dr...@gmail.com>.
Did you put a breakpoint on the serialization exception? I'd guess that
something in your component hierarchy is holding a reference to AccountDAO.
Wicket only proxies @SpringBean annotated variables.

Re: serialization problem with spring
Posted by Martin Grigorov <mg...@apache.org>.
My application uses wicket-spring and I tested kryo-serializer with it
while developing it. No problems at all with serializing JDK based
proxies or CGLIB based ones.
We don't use Spring Data-JPA nor any other kind of JDBC based backend...

Re: serialization problem with spring
Posted by Joe Fawzy <jo...@gmail.com>.
Hi
actually for testing , i tried using the new kryo-serializer from wicket
stuff
IT DOES NOT WORK, actually it has many more errors than the default one,
actuallly it cannot serialize a JdkDynamicProxy which is the basis for
injection
If someone have a solution or workaround , please help
Thanks
Joe

Re: serialization problem with spring
Posted by Joe Fawzy <jo...@gmail.com>.
Hi
i am living on the edge ,using wicket 1.5RC5.1 (the latest)
and also using the newly released Spring data-jpa project for data access
i do not use or reference PersistenceExceptionTranslationInterceptor
directly, actually i never know it is there till i saw that error
based on its name it is an interceptor which translate the jpa or jdbc
exception to spring's counterpart
in AccountManager there is an instance of AccountDAO which use this
persistence technology
i thought it might be a solution to use kryo serialization as it does not
require the object to be serializable, but the site does not recommend using
it in production as it is in its early stages and not yet stable
Any help please?
Thanks
Joe

Re: serialization problem with spring
Posted by Dan Retzlaff <dr...@gmail.com>.
Hi Joe,
Based on the depth of that serialization stack, I doubt it's your
AccountManager proxy that's giving you problems. I usually just breakpoint
NotSerializableException and walk up the stack to find the culprit. Any
change your CreatePage uses a method on AccountManager that returns an
object with PersistenceExceptionTranslationInterceptor, then holds a
reference to it? If so, that'll be a problem since Wicket doesn't know to
proxy that one.
