 Generally i cannot get thru a connection. Don't think is a code problem. Basically, becasue i've done it hundreds of times. But the sun1studio IDE it's a new tool to me, and besides, i'm not very good at installing and configurating, only at programing, if so. So there you go, likely it is  to be a configuration/install problem rather than a code problem. Still, at this point i only dare to say that i know nothing, so if you could help me out. I'm really having a mare and expecting it, any moment, to turn out to be a very silly thing.
 Thanks in advanced!!

PS: You may excuse my english, i'm a catalan.

1. What Version of MS-SQL 2000 are you running?

Run the following in Query Analyzer to find out:
SELECT @@Version
you should be up to 8.00.0760.03
If not, contact your DBA and see if they can install service pack 3
look here:

2. What version of JDBC do you have?

Microsoft has a bad track record with JDBC. There are some patches and third party JDBC's out there but they dont garuentee any but thier own.  Microsofts latest release is 2.2.0029
Look here:

Thanks for your help, nothing was wrong with the MS-SQL Server version (800.00.3xx) and i was using the exact same driver that could be found on the adress. But, however, by checking this things out, i've come out with a mid.term solution. Still, you were very helpfull and thanks to you i'm 'scratching'  again, thanks god. So there you're. Thanks again!
