Re: ClassCastException after retrieving an Entry

Ok I've put the code in. It now looks like the following.

Entry entry = javaSpace.take (taskTmpl, txn, 30000);
ClassLoaderUtil.displayClassLoaderTree(entry.getClass ().getClassLoader());
ClassLoaderUtil.displayClassLoaderTree(TaskEntry.class.getClassLoader());
...


and that is what I get.


ClassLoader Tree has 5 levels
cl0 -- Boot ClassLoader

cl1 -- ClassLoader sun.misc.Launcher$ExtClassLoader@92e78c:

Does that help?
