[jboss-user] Jboss class loading

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

I have also edited the Jboss-web.xml in the WAR web-inf folder to include:

<loader-repository>
      com.example:loader=APPbuild-Deployable-1.39-exp.war
</loader-repository>

this still does not seem to work at isolating the WARS?
