[jboss-user] [Installation, Configuration & DEPLOYMENT] - Classloader issues in JBoss 5.0.0

Hi Am using JBoss AS 5.0.0 on jdk5. Deployment of my war file fails. I see this error: ------------------------------------------------------------ 08:31:46,225 ERROR [StandardContext] Context [/myapp] startup failed due to previous errors java.lang.LinkageError: loader constraints violated when linking org/xml/sax/Parser class at com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl.newSAXParser(Unknown Source) at org.apache.tomcat.util.digester.Digester.getParser(Digester.java:704) at org.apache.tomcat.util.digester.Digester.getXMLReader(Digester.java:978) ------------------------------------------------------------- Seems like three might be conflict between jboss's "lib/endorsed/xercesImpl.jar" and my app's "WEB-INF/lib/xercesImpl.jar". I tried the following below. Created file "myapp.war/WEB-INF/jboss-web.xml" ----------------------------------- <jboss-web> <class-loading java2ClassLoadingCompliance='false'> <loader-repository> com.example:loader='myapp.war' <loader-repository-config>java2ParentDelegation=false</loader-repository-config> </loader-repository> </class-loading> </jboss-web> ----------------------------------- I removed the temporary files and restarted the webcontainer. But this didn't resolve the problem. How do I configure the classloading, to use my app's xercesImpl.jar over the one in JBoss ?
