NullPointerException in Tomcat
I am getting a NullPointerException, and the stack trace says it is down in the bowels of Tomcat somewhere. Can anyone give me any ideas of what might be wrong? Thanks Here is the stack trace: java.lang.NullPointerException at org.netbeans.modules.web.monitor.server.MonitorFilter.recordServletData(Moni torFilter.java:979) at org.netbeans.modules.web.monitor.server.MonitorFilter.getDataBefore(MonitorF ilter.java:545) at org.netbeans.modules.web.monitor.server.MonitorFilter.doFilter(MonitorFilter .java:180) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(Application FilterChain.java:213) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterCh ain.java:193) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.ja va:243) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:5 66) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:472) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:943) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.ja va:201) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:5 66) at org.apache.catalina.valves.CertificatesValve.invoke(CertificatesValve.java:2 46) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:5 64) at org.netbeans.modules.web.monitor.catalina.MonitorValve.invoke(MonitorValve.j ava:142) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:5 64) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:472) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:943) at org.apache.catalina.core.StandardContext.invoke(StandardContext.java:2344) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:164 ) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:5 66) at org.apache.catalina.valves.ErrorDispatcherValve.invoke(ErrorDispatcherValve. java:170) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:5 64) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:170 ) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:5 64) at org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:462) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:5 64) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:472) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:943) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java :163) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:5 66) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:472) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:943) at org.apache.catalina.connector.http.HttpProcessor.process(HttpProcessor.java: 1011) at org.apache.catalina.connector.http.HttpProcessor.run(HttpProcessor.java:1106 ) at java.lang.Thread.run(Thread.java:536) -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
RE: NullPointerException in Tomcat
When you mentioned the filters in my web app, I thought but I don't use any filters. Heck, I don't even know for sure what they are. But (and this is a big but), I am using the Tomcat that comes bundled with the Sun One IDE, and IT was putting both a filter and a valve into the server.xml file. I removed these and have been able to proceed. So it would assume there is some sort of problem with the Sun One IDE in this regard. Thanks! Brad -Original Message- From: Craig R.
