execute external command / application from java

Question

I'm looking for a package to support reliably executing external processes from Java. My criteria:

Abstract over OS. So if I want to run 'foo', it will look for 'foo.bat', 'foo.exe' under windows and 'foo' under other OSs (or, have a way of passing a map of os->command)
Being able to execute Java classes by simply giving the class name and arguments (so the package locates the java command, copies jvm flags and then executes)
Process stdout and stderr properly
Watchdog / Monitoring capabilities

I've looked at commons-exec but it looks like it answers only 3 & 4. Ant has support for execution but looks like an overkill to use it for this purpose only.

You will likely have to go with 'commons-exec' and then roll up your sleeves and write some code.

Those are pretty specific requirements.

Does this mean you've encountered this issue and did some research to find there's nothing available, or just by looking at the question it looks too specific to you?

I've worked on projects dealing with the last two points (3 & 4), and I've used commons-exec and Ant. But I have never seen a requirement similar to your first two points.
