perl <-> java

[der.hans]

moin, moin,

I'm working on a project that needs to interface with a java service.

I've been using perl and shell scripts for my side.

While I should be able to run my side of things on the same box as the
java service, that isn't guaranteed for the future.

The other team is letting me specify what communication mechanism we use,
the data format as well.

I'd like something that works with perl and java for the client side and
with java for the server side. I want to be able to run pure perl on the
client side, but am open to something that would be significantly easier
via perl using SWIG ( as Michael suggested ) or other library wrapper.

I think the communication needs to be encryptable. Not sure everyone will
agree with me, but since I get to specify what we use I'll choose
something that can be encrypted :).

If we run on seperate machines the two machines will initially be on the
same network, but that might change. Even when on different networks they
will be connected via a private network ( that might have transparent
tunnels ).

There is significant startup in calculating the initial response, but
subsequent related responses can take advantage of cacheing on the server
side.

I need to be able to request a cache be instantiated, request data and
request a cache be dropped. Being able to query if there is a cache for
and item and when it was instantiated would be good as well.

The format for the returned data is somewhat irrelevant, as long as it's
easily machine parsable.

What suggestions come to mind?

ciao,

der.hans
