Hello, I'm trying to precompile jsp pages with Ant before deploying a Web Archive.
The ant task I'm using is : <!-- ======== definition of jspc task ======= --> <taskdef classname="org.apache.jasper.JspC" name="jasper2"> <classpath> <path id="jspc.classpath"> <pathelement location="${java.home}/../lib/tools.jar" /> <!-- ======== My Jars, commented ================= --> <!-- <fileset dir="${source.libs.dir}"> <include name="*.jar" /> </fileset> --> <!-- ======== End of My Jars ===================== --> <fileset dir="${tomcat.home.dir}/server/lib"> <include name="*.jar" /> </fileset> <fileset dir="${tomcat.home.dir}/common/lib"> <include name="*.jar" /> </fileset> <fileset dir="${tomcat.home.dir}/bin"> <include name="commons-logging-api.jar" /> </fileset> </path> </classpath> </taskdef> Notice I commented the reference to the library directory. The task is then used by: <!-- ========================================= --> <!-- Compiles the jsp pages --> <!-- ========================================= --> <target name="jspc" depends="" description="Compile jsp pages with jasper2"> <mkdir dir="${jspc.src.dir}" /> <jasper2 verbose="1" validateXml="false" uriroot="${eclipse.my-app.dir}/web" webXmlFragment="build/WEB-INF" outputDir="build/WEB-INF/src" /> <javac destdir="${deploy.class.dir}" classpathref="jspc.classpath"> <src path="${jspc.src.dir}"> </src> </javac> </target> When I launch the task, I got the following error on a jsp file: org.apache.jasper.JasperException: file:C:/eclipse/workspace/MyWebApp/web/jsp/login/index.jsp(18,0) The value for the useBean class attribute myapp.jspbean.IndexJspBean is invalid. The error in the index.jsp file come from the line: <jsp:useBean id="indexJspBean" scope="session" class=" myapp.jspbean.IndexJspBean" /> As I thought that I should give to jspC a reference to the Bean, I tried to package the Bean in a jar file, put it in library directory and then uncommenting the reference to the libray directory in the previous ant file sample, but I got then the following error: [jasper2] java.lang.NullPointerException [jasper2] at org.apache.jasper.JspCompilationContext.createCompiler(JspCompilationCon text.java:220) [jasper2] at org.apache.jasper.JspC.processFile(JspC.java:809) [jasper2] at org.apache.jasper.JspC.execute(JspC.java:945) [jasper2] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) [jasper2] at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) [jasper2] at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) [jasper2] at java.lang.reflect.Method.invoke(Unknown Source) [jasper2] at org.apache.tools.ant.TaskAdapter.execute(TaskAdapter.java:123) [jasper2] at org.apache.tools.ant.UnknownElement.execute(UnknownElement.java:275) [jasper2] at org.apache.tools.ant.Task.perform(Task.java:364) [jasper2] at org.apache.tools.ant.Target.execute(Target.java:341) [jasper2] at org.apache.tools.ant.Target.performTasks(Target.java:369) [jasper2] at org.apache.tools.ant.Project.executeTarget(Project.java:1214) [jasper2] at org.apache.tools.ant.Project.executeTargets(Project.java:1062) [jasper2] at org.eclipse.ant.internal.core.ant.InternalAntRunner.run(InternalAntRunne r.java:633) [jasper2] at org.eclipse.ant.internal.core.ant.InternalAntRunner.run(InternalAntRunne r.java:412) [jasper2] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) [jasper2] at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) [jasper2] at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) [jasper2] at java.lang.reflect.Method.invoke(Unknown Source) [jasper2] at org.eclipse.ant.core.AntRunner.run(AntRunner.java:350) [jasper2] at org.eclipse.ant.internal.ui.launchConfigurations.AntLaunchDelegate$1.run (AntLaunchDelegate.java:182) [jasper2] at java.lang.Thread.run(Unknown Source) BUILD FAILED: C:\eclipse\workspace\MywebApp\build.xml:158: org.apache.jasper.JasperException I'm using the task shipped with tomcat 5.5.4. Have anyone an idea about what I'm missing ?
