Assuming an configuration problem on my PC to be the cause of my problem, I did successively: - desinstall tomcat 5.5.9 (there was one to test the web app) - desinstall jdk 1.5.0_03 and an anterior jdk 1.4 - install jdk 1.5.0_03, with standard directories option - install tomcat
After that I did a copy/paste in my build.xml of the jspc task found at http://jakarta.apache.org/tomcat/tomcat-5.5-doc/jasper-howto.html <target name="jspc"> <taskdef classname="org.apache.jasper.JspC" name="jasper2" > <classpath id="jspc.classpath"> <pathelement location="${java.home}/../lib/tools.jar"/> <fileset dir="${tomcat.home}/bin"> <include name="*.jar"/> </fileset> <fileset dir="${tomcat.home}/server/lib"> <include name="*.jar"/> </fileset> <fileset dir="${tomcat.home}/common/lib"> <include name="*.jar"/> </fileset> </classpath> </taskdef> <jasper2 validateXml="false" uriroot="${webapp.path}" webXmlFragment="${webapp.path}/WEB-INF/generated_web.xml" outputDir="${webapp.path}/WEB-INF/src" /> </target> First attempt, it still throw a NullPointerException ( java.lang.NullPointerException at org.apache.jasper.JspCompilationContext.createCompiler(JspCompilationContext.java:220 ) but I remarked a problem. The ant task assume that the presence of tools.jar at: <pathelement location="${java.home}/../lib/tools.jar"/> But the jdk 1.5 on windows install the following directories : C: +Program Files +Java +jdk1.5.0_03 +jre1.5.0_03 and make point ${java.home} to c:/Program Files/Java/jre1.5.0_03 and so cannot find tools.jar at ${java.home}/../lib/tools.jar ok, no problem. As I didn't want to modify the copy/pasted task from jasper-howto, I decided to use the jre shipped with jdk at c:/Program Files/Java/jdk1.5.0_03/jre. So I removed the jre from system, added the registry key for 1.5 - removed during jre desinstall - that point to the correct JavaHome, RuntimeLib and try again with a corrected ${java.home}. Unfortunately this second attempt failed too. NullPointerException is back . Aargh. For information, I set ${tomcat.home} to C:/Program Files/Apache Software Foundation/Tomcat 5.5 and the webapp.path is set to the directory c:/eclipse/workspace/myWebApp/build which has the following structure : +build +WEB-INF +classes my_classes_files +lib my_libs +src my_source_files web.xml +META-INF context.xml +some_jsp_directories index.jsp error.jsp so I arrived to a conclusion: it seems that I have 2 left hands :o) However If someone see a point to check... -- Nicolas -----Original Message----- From: Bernhard Slominski [mailto:[EMAIL PROTECTED] Sent: mercredi 22 juin 2005 11:07 To: 'Tomcat Users List' Subject: AW: Use JSPC Hi Nicolas, what jspc basically needs, is acces to all the internal tomcat libraries, as you see from the ant script: ${tomcat.home}/bin/*.jar ${tomcat.home}/server/lib/*.jar ${tomcat.home}/common/lib/*.jar As well as all the libraries from you web application. So what I did was just "installing" (unzipping) Tomcat on my deployment machine, just in order to the able to do the precomplation. I think you can also just download the deployer distribution (http://jakarta.apache.org/site/downloads/downloads_tomcat-5.cgi) this should contain all the stuff you need for the deployment. But I don't have experience with the deployer application. Conerning you web application: You need to include all the classes and libraries in the classpath as well, but it doesn't have to be under ${tomcat.home}/webapps it can be anywhere on your deployment machine. Maybe what's missing is that you have to include the /WEB-INF/classes directory too in your ant script. It's not in mine because I only use jar files in my webapp. Good luck!
