Jython (it has not been called jPython for a very long time) is an
implementation of Python that is written in Java and interoperates
well with Java libraries, both standard libraries and third-party
ones.

When you use jython, you do write Python code. The main differences
are in the library modules available; not all of the Python std lib is
available in Jython, and third-party modules that have compiled
extensions won't work.

Depending on what else your program does, and how big it is already,
jython may be a reasonable approach.

Another possibility might be calling a report writer from the command
line, if that is possible with any of the writers you are interested
in. You could also look at JPype though I don't know much about its
status.
