JSP precompilation, jspc, NullPointerException

[Bernhard Slominski <be...@zooplus.com>]

Hi,

I try to get the precompilation working with tomcat 5.5.7 under Windows NT.
I use the following target:
  <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> 

And I'm getting a NullPointer Exception (see below), looks like the Jasper
cannot be created.
Anyone has a clue why this happens?

Thanks for your help 

Bernhard
