Subject Re: Stopping/Killing a task ?
Date Thu, 22 Feb 2001 19:44:56 GMT
One plan is probably to have a lightweight wrapper that listens for a _kill_ signal of some

description.

I have some code that does something like this.
It wraps a process and can buffer the input/output and kill the process it wraps.

You run the other jvm from the java task with a fork but can get all the output back by running

the task again and issuing an different command.
eg
<target name="start">
  <wrapper command="java" signal="start" port="1234" address="localhost">
    <args etc etc etc> 
  <wrapper>
</target>
<target name="stop">
  <wrapper signal="stop" port="1234" address="localhost"/>
</target>
