[jboss-user] [Beginners Corner] - ClassNotFoundException in an ear application

[vamsin]

This might be a fundamental question:
I have a singleton class: SpringContext in a jar: context.jar  and is initialiazed by a InitServlet. This servlet is defined in web.xml and loaded from WEB-INF/classes. During init(ServletConfig..), the spring beans container is inited with few beans.

However, I have a jar that resides under myapp.ear directory which cannot access  the ContextLoader class that was already inited during Servlet load time.

How can I successfully use it in a class defined in the jar under myapp.ear?
