OK... after taking a closer look at ALL jboss-service.xml files in the deploy folder I found one with the element UseJK. It is in the JBOSS_HOME/server/all/deploy/jboss-web.deployer/META-INF directory. Hopefully this is what I am looking for. Maybe this coud be updatet in the clusterguides, if this realy is the correct place. THX Reinhard View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4125031#...
