Might be a DB2 driver/JCA configuration thing. I will take a look.

Thanks

That's what I suspected as well.

makes me think that this is what it is ...

I've opened this thread because I am about to release 1.0.1.SP4

This issue won't make it in SP4, it needs to be discussed here first.

Well.. we don't currently support DB2.

The config has not been tested like the other configs. If it hasn't been tested and on our roadmap, then, yes sure it's nice to have, but not something that can be in an official release, since we don't know if it works, or there are major problems that will prevent it from working.

I am currently testing the configs for 1.2. If someone has a request for DB2 then I will *try* and fit it in, although time is short. Otherwise a feature request should be added in JIRA and we will get around to it.

[ovidiu.feodorov]

Chances of a DB2 configuration making into release will improva a lot if whoever makes the request is also willing to contribute time to fix/test the configuration.

[timfox]

We can't put untested configs into a distro, unless we clearly mark them as "untested" - use at your own peril..

As I say, I will try and get DB2 in 1.2, and if passes the test suite it should be easy to backport to 1.0.x

[ovidiu.feodorov]

We won't. The issue has been moved to SP5 even before I started this thread.
