I have a wicket page (java class) which uses a service locater to execute
messages on a remote EJB. Though there is no direct reference to the EJB from
my wicket page there is a reference to the service locater which uses JNDI to
get a reference to the remote EJB. I get the following error (FYI, This error
does not happen in wicket 1.2 but happens in wicket 1.2.6).
WicketMessage: Internal error cloning object. Make sure all dependent objects
implement Serializable. Class: com.abc.wicket.LoginPage
Root cause:
java.io.NotSerializableException: com. abc.ejb. AFacadeBean. AFacadeBean
_7gl30w_EOImpl
The EJB implements javax.ejb.SessionBean which extends the serializable
interface but the EJB proxy object returned by the WebLogic server does NOT
implement serialzable. Below is the class hierarchy of the object located
through JNDI. (I printed this using reflectiion)
com. abc.ejb. AFacadeBean. AFacadeBean _7gl30w_HomeImpl
-weblogic.ejb20.internal.StatelessEJBHome
--weblogic.ejb20.internal.BaseEJBHome
---java.lang.Object
So it seems that I cannot use EJB's in wicket pages, (I am doing this
indirectly through service locaters to decouple the pages from the back end).
Any advice about what to do in this situation would be appreciated. Currently
I am running in deployment mode since this avoids the checking. I have given
some thought to marking the EJB transient in my service locator but would
like to hear any insights/design suggestions/advice
