Re: MONITOR/ON-ERROR blocks when calling Java (in Scott Klement's JDBCR4)

You could get it by calling the QMHRCVPM API. However, the RNX0301

actually is.

Also, some of the code in JDBCR4 bypasses IBM's Java support for RPG and
calls the JNI APIs directly. This won't have the string limitation, but
also won't send an RNX0301... so that case would have to be handled
separately.

Thanks. It's in my own additions, so the latter isn't especially relevant, and since I'm currently only checking to see if the root cause is a duplicate key, I've got plenty of space to find that.

While I was at lunch, QMHRCVPM did occur to me (although I had a brain-fart on the name), but I'd hoped there would be something easier. Oh, well, I've got it working well enough, so far, and that's what counts.
