I think it is an unknown bug in the jetty builder code and would
greatly appreciate your filing a jira issue with the details below.
Thanks!

Hello,
When requesting a JSP page of a geronimo-deployed WAR, I get the
following exception:
org.apache.jasper.JasperException: Unable to initialize
TldLocationsCache: $GERONIMO_HOME/config-store/17/lib1.jar
The webapp contains a META-INF/MANIFEST.MF file with a line like that:
Class-Path: lib1.jar lib/lib2.jar
I debugged into Jasper2 and found the following:
* The critical code is in TldLocationsCache.scanJars(), called from
init()
* This method is triggered at JSP compilation time, but only for pages
containing <%@ taglib ... %> directives
* At first, the JettyClassLoader is doing its stuff
* Second, its parent, o.a.g.kernel.config.ConfigurationClassLoader
takes over
* TldLocationsCache iterates the 2 libs from the Manifest file as
returned by ConfigurationClassLoader.getURLs()
* The URLs as returned by the CL are
$GERONIMO_HOME/config-store/17/lib1.jar
$GERONIMO_HOME/config-store/17/lib/lib2.jar
* But, the files are in fact stored under
$GERONIMO_HOME/config-store/17/war/WEB-INF/lib1.jar
$GERONIMO_HOME/config-store/17/war/WEB-INF/lib/lib2.jar
* This causes a FileNotFoundException which is wrapped into the
JasperException
* If the config-store is manipulated (while running the server) to
contain these two files at the requested location, everything works
fine from then on
* Of course, the downside of this manipulation is, that deployment
fails at next server startup
I wonder if this is a (known) bug with Geronimo's Classloader, or if
there is something wrong with my webapp (which can be run in
stand-alone Tomcat w/o any probs) or deployment?
I am running M4.
