Thanks Roman, that solved my problem. Although I have been using this
code for years now and all major JDBC drivers (Oracle, Postgres, JTDS,
HSQLDB, McKoi, Firebird 1.x, SQL Anywhere, DB2) worked without
problems. But reading the docs for setContextClassLoader() seems to
indicate that this should not create problems for other drivers.

One question though (this is getting a bit off-topic, I know). As this
is a multi-threaded application, do I need to set that for each and
every Thread I create, or is it sufficient to set this in the thread
that is loading and instantiating the driver?

Cheers and thanks for your help!
