Summary: EAR ClassLoader ignores library jar Class-Path
Initial Comment:
JBoss-3.2.1, j2sdk1.4.0_01, WinXP or Red Hat Linux 9.0.
The JBoss EAR ClassLoader does not appear to honour
the manifest Class-Path entries in either ejb-jar files
(declared as <ejb> modules in application.xml) or regular
library files contained within the EAR archive (packaged
as peers to ejb-jar files).
According to the J2EE specification and the JBoss
documentation the arrangement below should work
correctly, but it doesn't. By experiment I have
determined that declaring lib1.jar and lib2.jar as <java>
modules in application.xml solves the problem, but this is
clearly not the correct approach (java modules are
explicitly for client code).
Attached is the following test case that illustrates the
problem:
my-app.ear
META-INF/application.xml
my-ejb.jar
META-INF/MANIFEST.MF Class-Path: lib1.jar
tld/domain/MyEJB.class
tld/domain/MyEJBRemote.class
tld/domain/MyEJBRemoteHome.class
lib1.jar
META-INF/MANIFEST.MF Class-Path: lib2.jar
tld/domain/A.class
lib2.jar
tld/domain/B.class
my-client.jar
META-INF/MANIFEST.MF Main-Class:
tld.domain.MyClient
tld/domain/MyClient.class
Executing the run.cmd script launches MyClient, which
attempts to create an instance of the MyEJB bean. The
server throws the following exception:
