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

Okey, I found the solution. It was too easy to be seen and have nothing to do with the Geronimo. Sorry, this question should have been in the Stripes forum.

Answer lies in the url filter, it should accept actions from the WEB-INF/lib -folder too:

<param-name>ActionResolver.UrlFilters</param-name>
<param-value>/WEB-INF/classes,WEB-INF/lib</param-value>
