Since i been trying  to separate the app log in a independet log file i configure my jboss-app.xml like this. <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE jboss-app PUBLIC       "-//JBoss//DTD J2EE Application 1.4//EN" " http://www.jboss.org/j2ee/dtd/jboss-app_4_2.dtd http://www.jboss.org/j2ee/dtd/jboss-app_4_2.dtd"> <jboss-app>           <loader-repository>                     xxx=xxx.ear                     <loader-repository-config>java2ParentDelegation=false</loader-repository-config>           </loader-repository> </jboss-app> Also i added the log4j.jar which is necessary to make the magic and everything works (talking about log file) But,when my application is "deployed" the "ear" does not appear as deployed. After a google search and reading about class isolation i was trying to make it work adding jars (contained in jboss) but i dont know which one are necesary and not. Please,help. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/591684#591684] Start a new discussion in JBoss Web Services at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
