Hi, the second approach seems to work when using the --bootdir=dir option of run.sh instead of --patchdir. Here is what I did for testing purposes: 1) Added extra log-Statements to org.jboss.system.server.ServerImpl 2) Compiled that file with the Jar-Files of the jbossInstallDir/lib directory on the classpath 3) Put the compiled ServerImpl.class in a jar-File, say a.jar 4) Run the server with --bootdir=myDir where myDir contained a.jar 5) Received the log statements on the console But I'm not yet sure exactly when to use --bootdir and when to use --patchdir. Can someone please shed some light on this? Regards View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3958449#...
