Hi, Wonder if this is BEA WLS defect or my local configuration issue. running WLS 9.2 on PC window xp. confiugred Admin server and managed server under the same domain. Using/configuring a NodeManager to start all servers. Developed a Web Service and bundle it to an ear file. Try to deploy it (at "activate chnages") to managed server, failed due to following error(could not find tools.jar lib), however same ear deployed to admin server, running ok w/o problem. Exception preparing module: EJBModule(weblogic-timer-control.jar) Unable to deploy EJB: weblogic-timer-control.jar from weblogic-timer-control.jar: There are 1 nested errors: java.io.IOException: Compiler class: 'com.sun.tools.javac.Main', not found java.lang.ClassNotFoundException: com.sun.tools.javac.Main at ..... I configured tools.jar in the PRE_CLASS path in the startWeblogic.cmd as well as in the managed server configuration "Advanced" -> "prependClasspath", even add the tools.jar in the "server start" tab classpath. But all these efforts do not solve this error in managed server. Really appreciate if anyone can tell me what is going on here. Thanks, Tao
