Does anyone know why the JSPC Jasper compiler would throw a null exception on the following file. Within Tomcat 4.0,4.1,5.0 it works fine. However, pre-compiling it causes it to throw a exception as follows. The significant feature of the JSP file is that it uses a custom taglib.
Do I have to somehow give the japser compiler special options to locate the taglib, or does it work it out from the normal taglib definitions in the application's filesystem. The JSP file: <%@ taglib prefix="ihook" uri="/ihook" %> <%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %> <table width="80%" border="0"> <tr> <td><ihook:calendar baseURL="list.jsp?location=${webApp.webRoomBooking.location}" month="${webApp.webRoomBooking.prevMonth}" highlight="${webApp.webRoomBooking.date}" left="-3"/> </td> <td><ihook:calendar baseURL="list.jsp?location=${webApp.webRoomBooking.location}" month="${webApp.webRoomBooking.date}" highlight="${webApp.webRoomBooking.date}"/> </td> <td><ihook:calendar baseURL="list.jsp?location=${webApp.webRoomBooking.location}" month="${webApp.webRoomBooking.nextMonth}" highlight="${webApp.webRoomBooking.date}" right="3"/> </td> </tr> </table> The ant build tag is:jspc: <target name="jspc" depends="init"> <taskdef classname="org.apache.jasper.JspC" name="jasper2" > <classpath id="jspc.classpath"> <pathelement location="${java.home}/../lib/tools.jar"/> <fileset dir="${TOMCAT}/server/lib"> <include name="*.jar"/> </fileset> <fileset dir="${TOMCAT}/common/lib"> <include name="*.jar"/> </fileset> </classpath> </taskdef> <echo message="Tomcat is ${TOMCAT}"/> <jasper2 validateXml="false" uriroot="${SRC}" webXmlFragment="${SRC}/WEB-INF/generated_web.xml" outputDir="${SRC}/WEB-INF/src" /> </target> The verbose output is: [echo] Tomcat is F:/Tomcat4.1 [jasper2] Error in class org.apache.jasper.JspC 2003-12-01 11:06:36 - ERROR-the file '\roombooking\dates.jsp' generated the following general exception: java.lang.NullPointerException BUILD FAILED file:D:/Alex/Release/iHookWeb/build.xml:68: org.apache.jasper.JasperException: Error compiling \roombooking\dates.jsp at org.apache.tools.ant.TaskAdapter.execute(TaskAdapter.java:155) at org.apache.tools.ant.UnknownElement.execute(UnknownElement.java:193) at org.apache.tools.ant.Task.perform(Task.java:341) at org.apache.tools.ant.Target.execute(Target.java:309) at org.apache.tools.ant.Target.performTasks(Target.java:336) at org.apache.tools.ant.Project.executeTarget(Project.java:1339) at org.apache.tools.ant.Project.executeTargets(Project.java:1255) at org.apache.tools.ant.Main.runBuild(Main.java:609) at org.apache.tools.ant.Main.start(Main.java:196) at org.apache.tools.ant.Main.main(Main.java:235) Caused by: org.apache.jasper.JasperException: Error compiling \roombooking\dates.jsp at org.apache.jasper.JspC.processFile(JspC.java:596) at org.apache.jasper.JspC.execute(JspC.java:801) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39 ) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl .java:25) at java.lang.reflect.Method.invoke(Method.java:324) at org.apache.tools.ant.TaskAdapter.execute(TaskAdapter.java:147) ... 9 more --- Nested Exception --- org.apache.jasper.JasperException: Error compiling \roombooking\dates.jsp at org.apache.jasper.JspC.processFile(JspC.java:596) at org.apache.jasper.JspC.execute(JspC.java:801) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39 ) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl .java:25) at java.lang.reflect.Method.invoke(Method.java:324) at org.apache.tools.ant.TaskAdapter.execute(TaskAdapter.java:147) at org.apache.tools.ant.UnknownElement.execute(UnknownElement.java:193) at org.apache.tools.ant.Task.perform(Task.java:341) at org.apache.tools.ant.Target.execute(Target.java:309) at org.apache.tools.ant.Target.performTasks(Target.java:336) at org.apache.tools.ant.Project.executeTarget(Project.java:1339) at org.apache.tools.ant.Project.executeTargets(Project.java:1255) Alex --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
