Subject: WebappClassLoader won't load resource from jar file ?!?
I have a web app containing resource files in several jar files, but I am
unable to access the resources at runtime unless they are exploded into the
classes directory.
When trying to access the resource files using
ClassLoader.getResourceAsStream( "/meta-inf/com/kvasar/data.xml" ) I always
get null returned, even though that resource does exist inside a jar file in
the web app's WEB-INF/lib directory.
If I extract that resource to the classes directory, so I now have
WEB-INF/classes/meta-inf/com/kvasar/data.xml, then I get it fine using the
exact same path and ClassLoader - it works fine.
The Tomcat Class Loader HOW-TO is telling me that it should find it in the
jar.
I have this problem on Tomcat 4.0.1 & 4.1.24, Win 2K The ClassLoader
instance I am using for the getResourceAsStream() calls, is one that I get
from one of my classes that is deployed to my webapp in a war file. Logging
a toString() on this ClassLoader is shown below. Is it meaningful that it
doesn't list my jar files in it's list of repositories ??
