Local EJB references cannot be resolved when <inverse-classloading> is set in
web application
---------------------------------------------------------------------------------------------
Key: GERONIMO-3233
URL: https://issues.apache.org/jira/browse/GERONIMO-3233
Project: Geronimo
Issue Type: Bug
Security Level: public (Regular issues)
Affects Versions: 2.0-M6
Environment: Windows XP SP2
Reporter: Aman Nanner
Priority: Critical
Attachments: ejb-reference-fails.ear.zip
It seems that setting the {{<inverse-classloading>}} element in the
geronimo-web.xml for a web application causes Local EJB references to fail when
looked up. This is because a new SystemInstance is created via a different
classloader, and the existing SystemInstance singleton is not used. Here is a
stack trace of the error:
