Answer 1

for Tomcat 5.0 (You'll need to edit to fit your needs)
    <path id="jsp.classpath">       
        <!-- point classpath to directory containing jasper-compiler.jar and
               jasper-runtime.jar -->
        <fileset dir="C:\tomcat\common\lib">
            <include name="**/*.jar"/>
        </fileset>
        <fileset dir="C:/tomcat/common/endorsed">
            <include name="**/*.jar"/>
        </fileset>       
    </path> 
    <target name="jsp" >
    <!--
         The Ant JSPC task doesn't work with Tomcat 5.0
         so in the meantime we need to define our own task.
      -->
    <taskdef name="jspc50" classname="org.apache.jasper.JspC">
        <classpath>
                <path refid="jsp.classpath"/>    
        </classpath>
    </taskdef>
    <jspc50 outputDir="${build.classes}"
            package="jsp"
            uriroot="${project.dir}/web/webApp"
            webXmlFragment="c:/web.xml"
            verbose="9"
            validateXml="false">           
    </jspc50>
    <javac srcdir="${build.classes}/jsp"
           destdir="${build.classes}"
           debug="true"
           optimize="false"
           includes="**/*.java"
           source="1.4">
            <classpath>
                <path refid="classpath"/>
                <path refid="jsp.classpath"/>
            </classpath>          
    </javac>
</target>    More information can be found here :
