Re: ClassCastException after retrieving an Entry

Ok I modified the code again a little.



ClassLoaderUtil.displayContextClassLoaderTree ();
Entry entry = javaSpace.take (taskTmpl, txn, 30000);
ClassLoaderUtil.displayClassLoaderTree (entry.getClass ().getClassLoader());
Thread.currentThread ().setContextClassLoader (entry.getClass
().getClassLoader ());
ClassLoaderUtil.displayContextClassLoaderTree ();
ClassLoaderUtil.displayClassLoaderTree (TaskEntry.class.getClassLoader());
TaskEntry task = (TaskEntry) entry;




That is what it returns

I think the problem would be solved if I get TaskEntry to be loaded by the
RMIClassLoader. Am I right? Does anyone know how to do this?
