<target name="compile-jsp" depends="compile" description="precompile jsp">
    <java classname="com.caucho.jsp.JspCompiler" fork="true" failonerror="true">
      <classpath refid="resin.classpath" />

resin.classpath looks like this:

<path id="resin.classpath">
    <pathelement path="${build.classes.dir}" />
    <fileset dir="${resin.home}">
        <include name="lib/*.jar"/>
    </fileset>
    <fileset dir="${depends.run.dir}">
        <include name="**/*.jar" />
    </fileset>
    <fileset file="${polopoly.lib.dir}">
        <include name="**/*.jar" />
    </fileset>
</path>

and resin.home

<property name="resin.home" value="${user.home}/work/apps/resin"/>
