Re: CMP Bean problem

I am not sure this is a JDBC question, but I'll throw in my 2 cents
anyway..

I'll hazard a guess as to the cause of the problem: it might be that
you're inserting a 27-character value ("SuSE Linux Operating System")
into a 25-character field.

If I'm wrong, though... I've found CMP debugging can be tricky,
especially when the server defers database interaction to the end of the
EJB transaction to improve performance as it appears to be doing in your
case. The error from the database could pop up way after the
"offending" code executed. To really know what's going on, you'd better
follow the directions and pull out the SQLException contents, which
should contain the actual PostgreSQL error message. I'm not sure what
the steps are in SunONE to view an exception caught by the CMP layer, so
I can't help out there (maybe it's just because of the whiskey, but I
didn't see it in your log at first glance)
