Help! I can't do anything with my database even though i've connected!

Question

Hello,
I think I have properly connected to my MS SQL Server 2000 database, cause I'm not throwing any exceptions when I connect, but I can't insert or update any data, it displays error messages when i try to do either..i haven't tested delete cause its a database with empty tables. I think something has to be wrong iwth my database, cause this code works fine when i use jdbc-odbc with MS ACCESS 2000. I'll post my code here, just in case.

This error message is explained on MSDN site (Article Q313181). Here is an excerpt:
SYMPTOMS
While using the Microsoft SQL Server 2000 Driver for JDBC, you may experience the following exception:
java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Can't start a cloned connection while in manual transaction mode.
CAUSE
This error occurs when you try to execute multiple statements against a SQL Server database with the JDBC driver while in manual transaction mode (AutoCommit=false) and while using the direct (SelectMethod=direct) mode. Direct mode is the default mode for the driver.
RESOLUTION
When you use manual transaction mode, you must set the SelectMethod property of the driver to Cursor, or make sure that you use only one active statement on each connection as specified in the "More Information" section of this article.
