Java Stored Procedure in Oracle NoClassDefFoundError for Context class

A co-worker is trying to invoke a flow via a java stored procedure. He has this working with a standalone java client, but in Oracle he is getting a NoClassDefFoundError on the Context class. He has added the client.jar to his Oracle setup. He said it’s working with other classes such as ServiceException but not with Context.

Has anyone worked with java stored procs in Oracle that can shed some light on this?

Just a shot in the dark…

“Context” seems like it could be a commonly used classname. Might there be a conflict where the name is ambiguous? Normally this shows up at compile time but maybe something slipped through? What do the import statements look like? Might using the full name help?
