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
