Driver for SQL server

What is the best driver to use for SQL server?

My requirement is to have a type 4 open source driver. I am using jtds - is this a good choice?

Thanks!

Why don't you get the Java Drivers(type4) from the Microsoft website?

The Microsoft driver worked fine for me until it had a problem with the SSL implementation on my iSeries. Then I switched to the JTDS driver which is also working fine for me.

Why do you need an open-source driver? Do you expect you will need to look at the source code to debug problems?

I meant open source as being free. I was able to get it working with jtds and I wanted to confirm that it is dependable for production.

I will also check out the Microsoft drivers.

Thanks for your responses.
