Start Tomcat using an Ant target

I like using a direct call to the tomcat startup class so I can avoid shell scripts:

    <!-- start tomcat -->
    <target name="tomcat.start">
        <mkdir dir="${tomcat}/temp" />
        <mkdir dir="${tomcat}/logs" />
        <echo message="starting tomcat" level="info" />
        <java classname="org.apache.catalina.startup.Bootstrap"
              fork="true"
              failonError="false"
              dir="${tomcat}/bin"
              spawn="true">
            <classpath location="${env.JAVA_HOME}/lib/tools.jar" />
            <classpath location="${tomcat}/bin/bootstrap.jar" />
            <classpath location="${tomcat}/bin/commons-logging.api.jar" />
            <jvmarg value="-Dprocess.name=tomcat" />
            <jvmarg value="-Xmx800m" />
            <jvmarg value="-XX:MaxPermSize=350m" />
            <jvmarg value="-Dcom.sun.management.jmxremote.port=9003" />
            <jvmarg value="-Dcom.sun.management.jmxremote.ssl=false" />
            <jvmarg value="-Dcom.sun.management.jmxremote.authenticate=false" />
            <jvmarg value="-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager" />
            <jvmarg value="-Djava.util.logging.config.file=${tomcat}/conf/logging.properties" />
            <jvmarg value="-Djava.endorsed.dirs=${tomcat}/endorsed" />
            <jvmarg value="-Dcatalina.base=${tomcat}" />
            <jvmarg value="-Dcatalina.home=${tomcat}" />
            <jvmarg value="-Djava.io.tmpdir=${tomcat}/temp" />
            <arg value="start" />
        </java>
    </target>
