Execute external command / application from java

Question

I am looking for a package to reliably execute external processes with Java. My criteria:

• Abstract on the OS. Therefore, if I want to run "foo", it will look for "foo.bat", "foo.exe" under the windows and "foo" under other OSs (or have a way to send the os-> command card),
• The ability to execute Java classes by simply assigning the name and arguments of the class (so the package finds the java command, copies the jvm flags and then executes)
• Process stdout and stderr correctly
• Watchdog / Monitoring Functions

I looked at commons-exec, but it looks like it only answers 3 and 4. Ant has support for execution, but it looks like redundant to use it just for this purpose.

Answer 1

You will most likely have to go with "commons-exec" and then roll up your sleeves and write the code.

These are quite specific requirements.
