We use Java for one particular communications job in our software and it has
proven to be very fast and efficient. Actually, every one of the networks
with which we are certified has a dedicated Java for the HTTPS POST secure
communications. We benchmarked against the same HTTPS POST functionality in
RPG and the Java was an order of magnitude faster. Maybe that is a bit of
an exaggeration, but still way faster.
Our experience with this limited function has been exemplary. While no fan
of Java in any way, it seems like it could be a good tool. We do NOT use
Websphere at all, and from what I have heard, THAT is a whole OTHER world of
hurt. We have been told by IBM that they will not support Java as a
standalone language - meaning not running under Websphere. We have had a
few issues over the years, and their first question is what version of WS,
and when told we do not use it, their support evaporates. Feedback from our
customer base on Websphere is not glowing.
The Java Toolkit seems to be pretty bulletproof, as it has presented zero
issues over the many years that we have used it. All use of Java in our
system has the Java sitting on a data queue, waiting for a record to process
(transmit). The result is then sent back through another data queue to
another RPG program. This has been very effective for us, as we only have
to use the comm functions and avoid all data access in Java.
