Desperately seeking JDBC thin driver for Oracle 7 that works

I thought my JDBC connection (Unix -> Unix) to Oracle 7 was working fine... well, it was until I started next()'ing through a couple of ResultSets...now it gets up to about 400 next()'s OK, then dies with a SQLException as per the below example.

Quite a bit of experimentation shows that it is not a particular record that causes the problem, and although I can't rule out errors in my own code, the fact that others report a similar problem suggests it really is the Oracle JDBC thin
(type 4) driver that I am using - i.e. the one from Oracle's
web site - that is the problem.

This is quite a setback in an otherwise very successfull so far project...anybody know where I can get a type 4 driver that works ? WebLogic doesn't seem to have a type 4 driver for Oracle : what about Intersolve ? Somebody has posted a message referring to a driver from OpenLink - anybody know if it works OK ? Anybody know when Oracle are planning to fix their one ?

Thanks for any tips
