How to call ruby script from java and get results back

Hello Team,

I was wondering, and I did some unsuccessful search if I can do the
following:

From a Java class, invoke a Ruby (MRI) script and get any results produced
by the Ruby script back in the calling Java class.

Thank you

Whatever you mean by "result" - exit code, output to stdout, output to stderr...

You do it as for any external process in Java. For Java questions
there are better forums. :wink:

You could also consider to make use of JRuby - then you do not even
have to start a separate process...

Cheers

Hi
The other way round: call Java from within MRI would also be interesting.
How to avoid starting the Java-engine for every call? => run an app
containing the library and then call the functions only with two processes.
Are there other/better possibilities?

Robert Thank you.
I actually want to use Rubywmq, which is my understanding that it runs only
on MRI Ruby.

Thanks again
