Case matters, I've not used DB2 but are you certain the COM is capitalised?

I'd expect
com.ibm.db2.jdbc.app.DB2Driver
instead of
COM.ibm.db2.jdbc.app.DB2Driver


Also, you are cross-posting to four newsgroups, a lot of people will
have their newsreaders configured to treat highly cross-posted messages
as SPAM and ignore them. IME it is better to pick one newsgroup.

Followups set to c.l.j.d only.

Guys,

Thanks to all for your help - Arne was 100% right - it is my fault.
After receiving class not found conditions I copied db2java.zip and
db2jcc.jar to any possible directory - it does not help. I removed
these files, put to only 1 directory and using "properties" in
JBuilder I added pointed to this directory - and now my Java program
is working.
Thanks again!
