Could any one explain why this piece of code works fine: <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%> <%@ taglib prefix="x" uri="http://java.sun.com/jsp/jstl/xml"%> <%@ taglib prefix="s" uri="/struts-tags"%> <c:import url="/WEB-INF/classes/PageList.xml" var="pagelist" scope="application" /> <x:parse var="document" doc="${pagelist}"/> <html> <head> </head> <body> <br> <h1><x:out select="$document/pages/[EMAIL PROTECTED]'P001']/title"/></h1> </body> </html>
while this one: <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%> <%@ taglib prefix="x" uri="http://java.sun.com/jsp/jstl/xml"%> <%@ taglib prefix="s" uri="/struts-tags"%> <c:import url="/WEB-INF/classes/PageList.xml" var="pagelist" scope="application" /> <x:parse var="document" doc="${pagelist}"/> <html> <head> </head> <body> <br> <center> <!-- BEGIN of new code --> <s:form action="userauth"> <s:textfield label="User Name" key="username"/> <s:password label="Password" key="password"/> <s:submit/> </s:form> <!-- END of new code --> </center> </body> </html> gives the following error: XXXX-web-main: Servlet error java.lang.NullPointerException at org.apache.struts2.views.jsp.TagUtils.getStack(TagUtils.java:58) at org.apache.struts2.views.jsp.StrutsBodyTagSupport.getStack(StrutsBodyTagSupport.java:52) at org.apache.struts2.views.jsp.ComponentTagSupport.doStartTag(ComponentTagSupport.java:49) at _jsps._Login._jspService(_Login.java:103) at com.orionserver[Oracle Containers for J2EE 10g (10.1.3.3.0) ].http.OrionHttpJspPage.service(OrionHttpJspPage.java:59) at oracle.jsp.runtimev2.JspPageTable.compileAndServe(JspPageTable.java:724) at oracle.jsp.runtimev2.JspPageTable.service(JspPageTable.java:414) at oracle.jsp.runtimev2.JspServlet.internalService(JspServlet.java:594) at oracle.jsp.runtimev2.JspServlet.service(JspServlet.java:518) at javax.servlet.http.HttpServlet.service(HttpServlet.java:856) at com.evermind[Oracle Containers for J2EE 10g (10.1.3.3.0) ].server.http.ResourceFilterChain.doFilter(ResourceFilterChain.java :65) at org.apache.struts2.dispatcher.FilterDispatcher.doFilter(FilterDispatcher.java:413) at com.evermind[Oracle Containers for J2EE 10g (10.1.3.3.0) ].server.http.ServletRequestDispatcher.invoke(ServletRequestDispatcher .java:623) at com.evermind[Oracle Containers for J2EE 10g (10.1.3.3.0) ].server.http.ServletRequestDispatcher.forwardInternal(ServletRequestDispatcher .java:370) at com.evermind[Oracle Containers for J2EE 10g (10.1.3.3.0) ].server.http.HttpRequestHandler.doProcessRequest(HttpRequestHandler .java:871) at com.evermind[Oracle Containers for J2EE 10g (10.1.3.3.0) ].server.http.HttpRequestHandler.processRequest(HttpRequestHandler .java:453) at com.evermind[Oracle Containers for J2EE 10g (10.1.3.3.0) ].server.http.HttpRequestHandler.serveOneRequest(HttpRequestHandler .java:221) at com.evermind[Oracle Containers for J2EE 10g (10.1.3.3.0) ].server.http.HttpRequestHandler.run(HttpRequestHandler.java:122) at com.evermind[Oracle Containers for J2EE 10g (10.1.3.3.0) ].server.http.HttpRequestHandler.run(HttpRequestHandler.java:111) at oracle.oc4j.network.ServerSocketReadHandler$SafeRunnable.run(ServerSocketReadHandler.java:260) at oracle.oc4j.network.ServerSocketAcceptHandler.procClientSocket(ServerSocketAcceptHandler.java:239) at oracle.oc4j.network.ServerSocketAcceptHandler.access$700(ServerSocketAcceptHandler.java:34) at oracle.oc4j.network.ServerSocketAcceptHandler$AcceptHandlerHorse.run(ServerSocketAcceptHandler.java:880) at com.evermind[Oracle Containers for J2EE 10g (10.1.3.3.0) ].util.ReleasableResourcePooledExecutor$MyWorker.run(ReleasableResourcePooledExecutor .java:303) at java.lang.Thread.run(Thread.java:595) I'm stuck.
