firebird-java - Big Problem

Hi guys

I have a big problem!

I'm using InterBase 6.0 with interclient using Java 1.2.2 and I'm not avle to make an update of a Databae row!

All methods that i try to use seems not supported!!

To update a row on the DB I do:

- make a query on the DB

I get the response on the Object ResultSet

- then I try to update a single data of the row with ResultSet.updateInt(int col, int newData)

- and then I try to update the row on the DB using ResultSet.updateRow()

But seems that this method are not supported! How can I do an update?

Please I hope that someone can help me !!

Thanks a lot!
