How to Get JDBC Drivers

Dear all

how to get the about exact driver needed for Microsoft sql 2000 sp4 .

i had gone through the deployment process of JAR files from how to guides-- How To <b>Install and Configure External Drivers for JDBC & JMS Adapters</b>

i also checked the linked given in SDN threads to get the drivers (setup.exe)

but how can i confirm whether i had suitable drivers or not and one thing i had doubt ..

<b>the driver which i download will expire after some trial period...

my customer had licenced/purchased version MSSql2000, so will the

they might be having the exact drivers...</b>

can any one guide me the approach of getting the exact drivers...
