Agreed, storing Objects as MarshalledObjects is the Right Way to store things into the database so that they can be recovered, but that doesn't explain why when I store an Object via CMP, a byte array is returned on subsequent get()s. I can convert the byte array into an ObjectInputStream, pull out the MarshalledObject and then do a get() on that to restore the object, but that shouldn't be necessary. For an interface like this: public void setObject( String key, Object value ); public Object getObject( key ); and then attempt to use it: SomeEJB.setObject( "key", new URL( "http://www.foo.com"; ) ); URL url = (URL) SomeEJB.getObject( "key" ); I should _not_ be getting a ClassCastException (from memory: this happened last night, and I've kludged a work-around using Strings) when I call get(), but that's exactly what happens! I can extract the necessary bits from my code and send it to you as a simple test case if that would help....
