Subject [jira] Updated: (GERONIMO-2503) Webapp classloader prefers WEB-INF/lib over WEB-INF/classes
Date Thu, 19 Oct 2006 12:25:35 GMT
     [ http://issues.apache.org/jira/browse/GERONIMO-2503?page=all ]

Nikla Ratinen updated GERONIMO-2503:
------------------------------------

    Attachment: patch.txt
                test.war

A minimal web application to demonstrate the issue. Should print "Servlet loaded from WEB-INF/classes"
to System.out when servlet class loaded from WEB-INF/classes. 

Also, a patch against org.apache.geronimo.web.deployment.AbstractWebModuleBuilder to change
classloading order.

> Application classloader looks in WAR's WEB-INF/lib before WEB-INF/classes. This is in
violation of servlet 2.4 (and 2.3) specification, 9.5 Directory Structure, which states:
> "TheWeb application class loader must load classes from the WEB-INF/ classes directory
first, and then from library JARs in the WEB-INF/lib directory." 
> This behaviour prevents web application from overriding classes and resources from included
libraries.
