Thanks for the quick reply! I zipped the tomcat install and deployed it to my Win 7 machine where it works without issue.
When the custom error servlet fails to display, I get the stock tomcat http 500 error page. If I look at the access log, I see the 500 error: 192.168.xxx.xxx - - [02/Jun/2011:13:53:14 -0600] "POST /HMAApp/faces/main/TaskSearchTab.jsp HTTP/1.0" 500 1000 I also see the com.sun.rave.web.ui.appbase.ApplicationException and java.lang.NullPointerException in the localhost log file (both of which are set to display the custom error page in the application specific web.xml): Jun 2, 2011 1:53:14 PM org.apache.catalina.core.StandardWrapperValve invoke SEVERE: Servlet.service() for servlet Faces Servlet threw exception com.sun.rave.web.ui.appbase.ApplicationException at com.sun.rave.web.ui.appbase.faces.ViewHandlerImpl.cleanup(ViewHandlerImpl.java:559) at com.sun.rave.web.ui.appbase.faces.ViewHandlerImpl.renderView(ViewHandlerImpl.java:276) at com.sun.faces.lifecycle.RenderResponsePhase.execute(RenderResponsePhase.java:107) at com.sun.faces.lifecycle.LifecycleImpl.phase(LifecycleImpl.java:245) at com.sun.faces.lifecycle.LifecycleImpl.render(LifecycleImpl.java:137) at javax.faces.webapp.FacesServlet.service(FacesServlet.java:214) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:269) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:188) at com.sun.rave.web.ui.util.UploadFilter.doFilter(UploadFilter.java:198) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:215) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:188) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:172) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:117) at org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:581) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:108) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:174) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:879) at org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:665) at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:528) at org.apache.tomcat.util.net.LeaderFollowerWorkerThread.runIt(LeaderFollowerWorkerThread.java:81) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:689) at java.lang.Thread.run(Thread.java:662) Caused by: java.lang.NullPointerException at hmaapp.utilmanagement.OPProcMain.prerender(OPProcMain.java:2355) at com.sun.rave.web.ui.appbase.faces.ViewHandlerImpl.prerender(ViewHandlerImpl.java:771) at com.sun.rave.web.ui.appbase.faces.ViewHandlerImpl.renderView(ViewHandlerImpl.java:268) ... 22 more --------------------------------- On 02/06/2011 21:45, Kevin Claver wrote: > Two things I would like to note: >=20 > 1.

Tomcat 5.5.33 does correctly redirect to the error-page when runnin= g on a Windows 7 machine. The only time I have an issue is on the Linux = configuration above. The first things I'd check is whether there's something different about your Tomcat installation on Linux. You can ZIP the whole Tomcat install (including the app(s), if they're in tomcat/webapps) and transfer the file & unzip on your Linux install. Start it up & see if the same thing happens. Also: what error do you see, when the custom error servlet/page fails to display? Is it the same error as you expect or a different one? - if an NPE occurs in your app, do you see a 500 + NPE stacktrace? - or if a 500 occurs, do you see a 404? p
