Thanks for the quick response. tried that , but still fails to deploy . and then , the computer freeze, forcing me to reboot , thus no server console log to look for . Afterwards , prior to starting the server script , I deleted the problematic appz.war directory in the deploy, then the server failed to start and crashed (default mode) , with many exceptions in the server console . FYI, the war file contains all the needed libraries in WEB-INF/lib especially spring and hibernate . but where is the Spring2 and Hibernate3 deployer located by default in jboss? as i search for file name containing spring word in jboss-installation-directory nothing found, then searching after copying war directory to default/deploy only returned the spring jar files inside the appz.war/WEB-INF/lib only....
