howTo call an external process

[de...@canoo.com]

HI,
I need to call an external process from within my Java program and parse the
outputstream of the process.
What sort of built-in wrappers does ant have for this kind of task ?

Take a look at org.apache.tools.ant.taskdefs.Execute - this class
encapsulates the platform and VM specific logic of executing system
commands in an arbitrary directory and is used by several built-in
tasks (including <exec> and <java fork="yes">).

Hi Detlef,

rtfm.
Use the exec task to start your external process. The record task
will catch the output. All you have to do is to write a task that
does the parsing.

Cheers,

Ingmar
