I think the first place to look for executing Java from Org-mode code
blocks would be to check if any existing Emacs java modes already
provide support for interactive code evaluation.  When possible
piggybacking off of existing support modes is generally the easiest

See org/ob-C.el for an example of how to execute a code block which
requires compilation before execution.  I've (thankfully) managed to
avoid using Java throughout my CS career, so I'm not overly familiar
with the execution mechanics.  There are numerous examples in the ob-*
files of languages which write code block bodies to external files and
then pass those files to executables.

beanshell looks like it may provide the best option for :session
evaluation, however if no inferior java mode currently exists I would be
hesitant to try to wrap beanshell directly.
