Iam trying to deploy a struts application on Websphere Application Server 3.5 Patch 2. Could some one explain what happens from a Struts Point of view when we restart the application Server. I think that the webapp is being started and in the process the servlets will be added to the container. Now since the webapp failed to start there is no way I can test the servlets or JSP. I see the following text in the application log. What could possibly be wrong? (Checked with the kwicprototype.webapp file in servlets directory, it seems to be OK) Regards pathangi r [01.07.18 11:05:23:397 CDT] e0df446a ServletHost A Restarting group: "kwicprototype" [01.07.18 11:05:23:403 CDT] e0df446a ServletInstan A SRVE0097I: Servlet unload initiated: "Error Reporting Facility" [01.07.18 11:05:23:404 CDT] e0df446a ServletInstan A SRVE0107I: Servlet has become permanently unavailable for service: "Error Reporting Facility" [01.07.18 11:05:23:404 CDT] e0df446a WebGroup A SRVE0091I: [Servlet LOG]: "Error Reporting Facility: destroy" [01.07.18 11:05:23:406 CDT] e0df446a ServletInstan A SRVE0021I: Servlet unloaded: "Error Reporting Facility" [01.07.18 11:05:23:406 CDT] e0df446a ServletInstan A SRVE0097I: Servlet unload initiated: "JSP 1.1 Processor" [01.07.18 11:05:23:407 CDT] e0df446a ServletInstan A SRVE0107I: Servlet has become permanently unavailable for service: "JSP 1.1 Processor" [01.07.18 11:05:23:408 CDT] e0df446a ServletInstan A SRVE0021I: Servlet unloaded: "JSP 1.1 Processor" [01.07.18 11:05:23:460 CDT] e0df446a ServletInstan A SRVE0048I: Loading servlet: "Error Reporting Facility" [01.07.18 11:05:23:460 CDT] e0df446a WebGroup A SRVE0091I: [Servlet LOG]: "Error Reporting Facility: init" [01.07.18 11:05:23:461 CDT] e0df446a ServletInstan A SRVE0130I: Servlet available for service: "Error Reporting Facility" [01.07.18 11:05:23:469 CDT] e0df446a ServletInstan A SRVE0048I: Loading servlet: "JSP 1.1 Processor" [01.07.18 11:05:23:470 CDT] e0df446a WebGroup A SRVE0091I: [Servlet LOG]: "JSP 1.1 Processor: init" [01.07.18 11:05:23:471 CDT] e0df446a ServletInstan A SRVE0130I: Servlet available for service: "JSP 1.1 Processor" [01.07.18 11:05:23:471 CDT] e0df446a ServletHost X Failed to restartWebGroup {0} "kwicprototype" com.ibm.servlet.util.REException: /* at com.ibm.servlet.util.RegexpPool.add(RegexpPool.java(Compiled Code)) at com.ibm.servlet.util.RegexpPool.add(RegexpPool.java:55) at com.ibm.servlet.util.StringMatcher.put(StringMatcher.java:136) at com.ibm.servlet.engine.ServletHost.restartWebGroup(ServletHost.java:157) at com.ibm.servlet.engine.ServletEngineDynamicUpdateSupport.restartWebGroup(Ser vletEngineDynamicUpdateSupport.java:105) at com.ibm.ejs.sm.active.ActiveServletGroup.setRefreshConfigAction(ActiveServle tGroup.java:193) at java.lang.reflect.Method.invoke(Native Method) at com.ibm.ejs.sm.agent.AdminAgentImpl.activeObjectInvocation(AdminAgentImpl.ja va(Compiled Code)) at com.ibm.ejs.sm.active.ActiveObject.invokeContainedObject(ActiveObject.java:4 73) at com.ibm.ejs.sm.agent.AdminAgentImpl.activeObjectInvocation(AdminAgentImpl.ja va(Compiled Code)) at com.ibm.ejs.sm.active.ActiveObject.invokeContainedObject(ActiveObject.java:4 73) at com.ibm.ejs.sm.agent.AdminAgentImpl.activeObjectInvocation(AdminAgentImpl.ja va(Compiled Code)) at com.ibm.ejs.sm.agent.AdminAgentImpl.invokeActiveObject(AdminAgentImpl.java:6 2) at com.ibm.ejs.sm.agent._AdminAgentImpl_Tie._invoke(Unknown Source) at com.ibm.CORBA.iiop.ExtendedServerDelegate.dispatch(Unknown Source) at com.ibm.CORBA.iiop.ORB.process(Unknown Source) at com.ibm.CORBA.iiop.WorkerThread.run(Unknown Source) at com.ibm.ejs.oa.pool.ThreadPool$PooledThread.run(ThreadPool.java(Compiled Code))
