[jboss-user] UseJBossWebLoader True or False (which setting means isolated)

Hi, I have just setup a jboss 4.2.3 server and I have deployed 10 applications all the applications are WAR files and all of them contain saxon.jar. When I leave the value: UseJBossWebLoader to its default to false.... however this causes exceptions. if I set this to true, everything seems happy? reading the config <!-- A flag indicating if the JBoss Loader should be used. This loader uses a unified class loader as the class loader rather than the tomcat specific class loader. The default is false to ensure that wars have isolated class loading for duplicate jars and jsp files. --> false One would think that to have isolated you leave this value as is? However in my experiance this is not the case. Can someone please confirm if I am wrong or not? If I am not the config file and the wiki documentation should be updated. Just to note: Jboss version 4.2.3: file edited /opt/jboss/server/test/deploy/jboss-web.deployer/META-INF/jboss-service.xml
