Communication between JAVA and python

[Jacques Daussy]

Hello
How can I transfert information between a JAVA application and a python
script application. I can't use jython because, I must use python
interpreter.I think to socket or semaphore, but can I use it on Windows
plateform ?

thanks a lot

Jython has an interpreter and Windows has sockets.

Well, it all depends on the exact deployment scenario you;re facing.

If you're java program can be embedded dinside hte python scripts, then
JPype (see my sig at the bottom of this post) can certainly help you.

Otherwise ... Is there a java way to "access" you java program from
outside it's process? I mean things like RMI servers, or EJBs. If so,
again JPype can take the place of a "java" client.

If not, there is no magic. You must first find a way to contact you Java
process. If that remote-call technology is "standard", i.e. Something
like SOAP or XML-RPC, then you can find a python technology to access
it. If its not standard, but tehre is a Java way to use it, Again jpype
can be your friend.

If you can tell us more about the nature of each program (Python and
Java) we may be better able to help you.

Try XML-RPC (a simple implementation of remote procedure call via HTTP
sockets).
It's built-in in Python since 2.2
(http://www.python.org/doc/2.4/lib/mo...mlrpclib.html),
in Java use e.g. Apache XML-RPC (http://ws.apache.org/xmlrpc/).
