A Jenkins instance is deployed through Tomcat 6 in Win7. A Jenkins job is configured by invoking a ws_ant(ibm extension of ant) script to build and deploy a Java ee application to a WAS 6.1 server instance. The ws_ant script runs with same success either at windows terminal or at Jenkins. However, server turns itself into stop state within one minute after it was started up by Jenkins. In contrast, the was server stays on after the script is executed at terminal. I examined the server log. There are exceptions, but the server exception logs are the same for Jenkins and terminal case.
