I've never used Mobicents before so I don't have the first clue, but a quick google on "mobicents classloader" returns this as the first result:

>From that link: "Working with classpaths/URLs would result the same class to be loaded in multiple classloaders, and then you would have linkage errors when passing from one component to other..."  Sounds familiar. :)  There should be some solution in Mobicents for passing objects between components such that they share a common class.
