JspC ClassNotFoundEception on First Run
I'm using the JspC task in ant to precompile my jsps and for some reason it
fails with a ClassNotFoundException on the first run but succeeds on the
second. Does anyone know why or how I can resole the issue?
I'm using tomcat 4.1.24 and here's the section in my build.xml that is
failing:
<taskdef classname="org.apache.jasper.JspC" name="jspc2">
<classpath id="jspc.classpath">
<pathelement location="${java.home}/../lib/tools.jar"/>
<fileset dir="${tomcat.dir}/server/lib">
<include name="*.jar"/>
</fileset>
<fileset dir="${tomcat.dir}/common/lib">
<include name="*.jar"/>
</fileset>
</classpath>
</taskdef>
<jspc2 uriroot="${dist.dir}/webapp"
webXmlFragment="${build.dir}/WEB-INF/generated_web.xml"
outputDir="${build.dir}/WEB-INF/src"/>
And here's the exception:
