Java Wrapper To Perl/python Code

I have to deploy some Web Services on a server that only supports the Java ones, but some of them will be done using perl or python. I want to know if is possible to develop a Java

Solution 1:

This depends heavily upon your needs. If Jython is an option for the Python code (it isn't always 100% compatible), then it is probably the best option there. Otherwise, you will need to use Java's Process Builder to call the interpretters directly and return the results on their output stream. This will not be fast (but then again, Jython isn't that fast either, relative to regular Java code), but it is an extremely flexible solution.

Solution 2:

For the Python part of it you can use Jython to run Python code right from your Java virtual machine. It'll integrate fully with your Java code as a bonus.

Solution 3:

For Perl, use Inline::Java. There are several options for integrating the code; you can call a separate process or you can use an embedded interpreter.

Solution 4:

For Python you can use the Java Scripting API. A Perl implementation is sadly still missing.

Solution 5:

There's something I used a while back called Jython which allows you to execute Python code from Java. It was a little quirky, but I got it to do what I needed.
