http://issues.apache.org/bugzilla/show_bug.cgi?id=27969 RequestDispatcher.include() results in NullPointerException Summary: RequestDispatcher.include() results in NullPointerException Product: Tomcat 5 Version: 5.0.19 Platform: PC OS/Version: Linux Status: NEW Severity: Major Priority: Other Component: Catalina AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] Background: * JBoss 3.2.4RC1 w/Tomcat 5.0.19. * Two webapps: /com.loudcloud.owm.usrmgr, /com.loudcloud.owm.shared * Inside page /com.loudcloud.owm.usrmgr/domain.jsp, it includes the content of another JSP from another webapp /com.loudcloud.owm.shared/header.jsp. It does so by getting a request dispatcher ServletContext ctx2 = pageContext.getServletContext().getContext("/com.loudcloud.owm.shared"); RequestDispatcher dispatcher = ctx.getRequestDispatcher("/header.jsp"); dispatcher.include(request, response) This results in the following NullPointerException in Catalina (see stack trace below). Also worth mentioning is that both webapps /com.loudcloud.owm.shared and /com.loudcloud.owm.usrmgr have a Filter set up in the web.xml. Only the filter in the /com.loudcloud.owm.usrmgr/domain.jsp request was invoked. The filter /com.loudcloud.owm.shared/header.jsp was not invoked. Is that the correct behavior with Servlet 2.4? ------------------------------------------------------ 2004-03-25 16:15:25,323 FATAL [org.apache.jasper.runtime.JspFactoryImpl] Exception initializing page context java.lang.NullPointerException at org.apache.catalina.core.ApplicationHttpRequest.getSession(ApplicationHttpRequest.java:546) at org.apache.catalina.core.ApplicationHttpRequest.getSession(ApplicationHttpRequest.java:512) at javax.servlet.http.HttpServletRequestWrapper.getSession(HttpServletRequestWrapper.java:268) at org.apache.jasper.runtime.PageContextImpl._initialize(PageContextImpl.java:192) at org.apache.jasper.runtime.PageContextImpl.initialize(PageContextImpl.java:167) at org.apache.jasper.runtime.JspFactoryImpl.internalGetPageContext(JspFactoryImpl.java:149) at org.apache.jasper.runtime.JspFactoryImpl.getPageContext(JspFactoryImpl.java:106) at com.loudcloud.owm.shared.header_jsp._jspService(header_jsp.java:52) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:133) at javax.servlet.http.HttpServlet.service(HttpServlet.java:856) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:284) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:204) at org.apache.catalina.core.ApplicationDispatcher.invoke(ApplicationDispatcher.java:750) at org.apache.catalina.core.ApplicationDispatcher.doInclude(ApplicationDispatcher.java:636) at org.apache.catalina.core.ApplicationDispatcher.include(ApplicationDispatcher.java:546) at com.loudcloud.ps.taglib.GenericBodyTag.doEndTag(GenericBodyTag.java:97) at com.loudcloud.owm.usrmgr.domain_jsp._jspService(domain_jsp.java:142) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:133) at javax.servlet.http.HttpServlet.service(HttpServlet.java:856) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:284) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:204) at com.opsware.owm.util.channel.ChannelFilter.doFilter(ChannelFilter.java:173) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:233) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:204) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:257) at org.apache.catalina.core.StandardValveContext.invokeNext(StandardValveContext.java:151) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:567) at org.apache.catalina.core.StandardContextValve.invokeInternal(StandardContextValve.java:245) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:199) at org.apache.catalina.core.StandardValveContext.invokeNext(StandardValveContext.java:151) at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:587) at org.apache.catalina.core.StandardValveContext.invokeNext(StandardValveContext.java:149) at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:66) at org.apache.catalina.core.StandardValveContext.invokeNext(StandardValveContext.java:149) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:567) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:184) at org.apache.catalina.core.StandardValveContext.invokeNext(StandardValveContext.java:151) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:164) at org.apache.catalina.core.StandardValveContext.invokeNext(StandardValveContext.java:149) at org.jboss.web.tomcat.tc5.jca.CachedConnectionValve.invoke(CachedConnectionValve.java:92) at org.apache.catalina.core.StandardValveContext.invokeNext(StandardValveContext.java:149) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:567) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:156) at org.apache.catalina.core.StandardValveContext.invokeNext(StandardValveContext.java:151) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:567) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:972) at org.apache.coyote.tomcat5.CoyoteAdapter.service(CoyoteAdapter.java:206) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:833) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.processConnection(Http11Protocol.java:732) at org.apache.tomcat.util.net.TcpWorkerThread.runIt(PoolTcpEndpoint.java:619) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:688) at java.lang.Thread.run(Thread.java:534) --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
