ClassCastException deploying Continuum.war on JBoss-5.0.0.GA
------------------------------------------------------------
Key: CONTINUUM-2049
URL: http://jira.codehaus.org/browse/CONTINUUM-2049
Project: Continuum
Issue Type: Bug
Components: Environmental
Affects Versions: 1.2.3
Environment: Windows Server 2003 R2 and XP SP3, Sun JDK JVM 1.6.0_11,
running JBoss 5.0.0.GA
Reporter: Bob Walker
Priority: Minor
Attachments: stacktrace.txt
I'm launching the default server configuration for a clean JBoss 5.0.0.GA
installation and deploying continuum.war into the deploy/ directory.
Having tried to adapt the instructions for 4.x.x here:
http://docs.codehaus.org/display/CONTINUUMUSER/Continuum+on+JBoss
, I've set up data sources and made the derby jar available.
When I start the server or redeploy, I get a ClassCastException:
org.apache.xerces.jaxp.DocumentBuilderFactoryImpl cannot be cast to
javax.xml.parsers.DocumentBuilderFactory
I tried removing log4j and some of the xml-related jars as described in the
Archiva/JBoss doc here:
http://cwiki.apache.org/ARCHIVA/archiva-on-jboss.html
This gets me further, but fails with the same error when loading spring context
configuration further down the road.
I've also tried removing xalan/xerces and letting it use the default endorsed
version supplied by JBoss, this gives me different ClassLoader errors, at which
point I gave up and began writing my findings here.
I'm guessing it's a fairly simple classloader issue with xalan and xerces, but
it's got me stumped. Any hints? I've tried it with v1.3.1 as well, with the
same result.
