Mark,
I have a working solution for pre-compiling jsp, that I am using successfully with all
our tomcat installations. The target looks
like :
<target name="jspc_preparse" description="Use Jasper2 to parse jsp into java">
<mkdir dir="${webapp.workdir}"/>
<jspc
srcdir="${webapp.rootdir}"
destdir="${webapp.workdir}"
failonerror="false"
classpathref="jspc_parse.classpath"
package="org.apache.jsp"
compiler="jasper41">
<exclude name="**/WEB-INF/**"/>
<exclude name="include/**"/>
</jspc>
<!-- Fix all the package names -->
<replaceregexp
match="^package org.apache.jsp.*;"
replace="package org.apache.jsp;" >
<fileset dir="${webapp.workdir}" >
<include name="**/*.java" />
</fileset>
</replaceregexp>
</target>
I then use <foreach> from antcontrib to iterate over the directories and compile them
individually.
Tomcat seems to accept all the resulting class files at runtime with no problems.
Regards,
Steph
