Stop Tomcat cleanly using Ant

Hello,
As part of my ANT build script I need to shut down tomcat, clean some stuff up then do a clean deployment.  I stop tomcat with the following target.

<!-- Stop Tomcat -->
    <target name="stop.tomcat">
        <java classname="org.apache.catalina.startup.Bootstrap" fork="yes">
            <jvmarg value="-Dcatalina.home=c:\tomcat" />
            <arg value="stop" />
            <classpath>
                <fileset dir="c:\tomcat">
                    <include name="bin/bootstrap.jar" />
                </fileset>
            </classpath>
        </java>
    </target>

This stops the server but leaves the window open.  The final line in the window says
[java] Stopping service Tomcat-Standalone.  If I navigate to the server it seems to be shut down.

Problem is that when my script goes to clear out the shared/lib folder on tomcat I get the following error:
BUILD FAILED
file:C:/cruisecontrol/work/build.xml:169: Unable to delete file T:\shared\lib\ac
tivation.jar

(I don't think the problem has anything to do with activatipon.jar specifically its just the first alphabetically)

If I close the tomcat window manually the problem goes away.  Any idea on how I can shut down cleanly using ANT.

Thanks in advance.
Bruce

Could you use the exec task to call the shutdown.bat file?

<exec dir="${tomcat_bin}" executable="shutdown.bat" os="Windows 2000" output="dir.txt">
</exec>

(or something like that ;-))

Thanks for the thought.  Unfortunately I tried that and get basically the same result.

>>Unable to delete ...

Are any of those files/libraries in use by the stop.tomcat task?

That's an interesting thought.  May well be.  Let me investigate a little and I will get back to you.

Thanks

Do you need a pause in the ant script to give Tomcat time to actually stop?

I don't know if I can help much further.  The following ant script works fine on my system:

<?xml version = '1.0' encoding = 'ISO-8859-1' ?>
<project name="TomcatStopper" default="killit">
  <target name="killit">
    <exec executable="/var/tomcat5/bin/shutdown.sh" os="Linux" output="shutdown.txt">
    </exec>
  </target>
</project>

However, there are some obvious differences ;-)  I'm using Linux and I also suspect that you're running Tomcat 4.

If this was the problem, then a different error would have been reported using the exec task (I *think* ;-))

Does "basically the same result" mean exactly the same result?

Exaclty the same I am afraid.  Unforunately re:

Seemed plausible as I had duplicate jars in shared\lib and common\lib  but I still have the same problem after removing them.

So you're now 100% certain that any files you're trying to delete are not in use by Ant itself?

No, actually I think you ARE onto something I just need some time to test a couple of things.  I just want to make sure i can re-create the problem consistently and fix it with your solution.  At first glance it seemed to not work but there are three apps all with there own libs and several dupe jar files.

>>Are any of those files/libraries in use by the stop.tomcat task?
