Use bat-file with exec

[Peter Kesch]

I try to stop and restart the tocat WebServer by Ant.
But with
<exec executable="cmd.exe">
    <arg value="${tomcat}\bin\startup.bat" /> i also tried <arg 
value="c:\tomcat-3.2.3\bin\startup.bat" />
</exec>

it doesn't work.

i see only the message of cmd and than it hangs.
With STRG+C i can break it but TOmcat isn't started.

Has anyone a Hint 

Peter
