Hi,

We are using webmethods 6.1 IS and JDBC adapter 6.0.3 and Sql server 2000. We are going to upgrade our database to Sql server 2008.

Shall we need to change the JAR file in IS/lib/jars. If so ,Could you please provide the Jar file for Sql server 2008 and datasource class name which we need to give in connection properties.
