Re: Could not locate class in jar package in the WEB-INF/lib folder - classloader problem?

Hello

I have created a very simple web application just with a login page (index.jsp). Application is using geronimo 2.1.

My application ear contains:

MyWebApplication.ear:
  MyBackEndComponents.jar
  commons-logging-1.1.1.jar
  log4j-1.2.15.jar
  spring.jar
  MyGui.war

and the war contains (among other stuff):

MyGui.war:
  index.jsp
  WEB-INF
     lib
       cos.jar
       stripes.jar
       MyStripesActions.jar


Now, I would assume that Stripes actions in the MyStripesActions.jar package would be available, but they are not (classNotFound kind of exception it thrown: net.sourceforge.stripes.exception.StripesServletException: Could not locate an ActionBean that is bound to the URL [/Login.action].). Basicly it means that Stripes could not locate the Login-action class.

If I extract MyStripesActions.jar package and put those action classes into WEB-INF/classes folder, application is working as it should.

Why the geronimo could not load the the jar package?

Thanks in advance and regards,
Timo Ratilainen
