Running an Apache Ant build process (or another command line process) from Orbeon XPL

Is there a way to do to start an Apache Ant build process from an Orbeon XPL pipeline and/or a way to start other command line processes?

Ideally, I would like to start the processor from the scheduler as depicted below as this could give me much more flexibility on how the processes are run...

<p:processor name="oxf:scheduler">
<p:input name="config">
<config>
<start-task>
<name>Apache Ant precompile</name>
<start-time>now</start-time>
<interval>0</interval>
<synchronized>true</synchronized>
<processor-name>oxf:pipeline</processor-name>

<input name="config" url="oxf:/apps/template/views/build.xml"/>
</start-task>
</config>
</p:input>
</p:processor>

I am new to Orbeon and it would useful for me to be able to integrate with previous XML pipelines which I had written in Ant. Many of the processes do things like caching, precompling code and backing up data from various systems - I may be able to migrate many of these to Orbeon in the longer term but probably not all of them.

I don't know if it still in the most recent builds, but there is an
execute processor that lets your run a command line program:

<p:processor name="oxf:execute-processor">
<p:input name="config">
<exec dir="/path-to-run-in"
executable="/path-to-perl-program">
<arg line="-options -to -pass"/>
</exec>
</p:input>
<p:output name="stdout" id="stdout"/>
<p:output name="stderr" id="stderr"/>
<p:output name="result" id="result"/>
</p:processor>

In the case of Ant, since it is java, you might be able to use the
delegation processor.

Hank,

Many thanks for your help this appears to work great with my build which is one of the more recent development versions! Now I know what am looking for I have also managed to picked up on the previous thread you answered at http://mail-archive.ow2.org/ops-users/2009-05/msg00000.html, your postie at http://www.pastie.org/466942 and documentation which are also very useful...

Delegation documentation: http://www.orbeon.com/orbeon/doc/processors-delegation

http://www.orbeon.com/orbeon/doc/home-changes-35 >> 3.14. Other Enhancements >> New Execute processor. A new Execute processor has been added. It allows executing external commands and retrieving the command's standard output and standard error.

Kind Regards,
Gary

PS The execute bit ran find when I tested as below and now I am working at passing in params as in your XSL postie example
<exec
executable="E:\eclipse\plugins\org.apache.ant_1.7.1.v20090120-1145\bin\ant.bat"
dir="G:/workspaces/websites/testsite">
<arg line="build-sitemap"/>
</exec>
