salue,

just a short intermediate:

Think about the performance. XML-RPC brings a tenth of CORBA in
throughput.

I did some tests with Xindice and some with eXist some month ago and as
far as this is comparable at all, there is a huge gap in msg/sec during
storing. I didn't check for retrieval since I always know the id of the
document in my case.

So even if I bother with the CORBA due to a ORB conflict I wouldn't give
it away like nothing without thinking it over again.

regards

Heinrich
