Does anybody use Plain java API instead of CURL when doing something from zOS to RTC?
We're doing some process orchestration from RTC to zOS and we need to update work items status from zOS.
At the moment we're using curl and everything works but we think we loose some time parsing around json with Rexx. So we would like to try to do the same things using plain java api on zOS (they should work...just jar libraries). Does anybody use plain java api in zOS? (We're on RTC 2.0.0.2 iFix 6...)

We tried a simple "copy jar on zOS" approach and we got this error just trying to execute a class to connect to RTC

May 07 '13, 11:44 p.m.I only use Rexx/cURL on z/OS to connect to RTC Work Items or anything else in Jazz through OSLC. You mention you lose time parsing around json with Rexx, but there is also time spent starting up java that you do not encounter. So, I guess to get the real truth, you would have to test both solutions side by side. I've followed this approach as I am assuming that more people on z/OS know Rexx than Java, so, that is what I've done. I guess I do have more File I/O with Rexx/cURL though.
