Netbeans - JDBC Driver Class

Does anyone use Netbeans to connect to PostgreSQL?

I have connected 7.3.1, and I can connect because I can run SELECT
statements from Netbeans. However when I try the "Test Driver" or launch a
JSP in the browser I get:

Type Exception report

message Internal Server Error

description The server encountered an internal error (Internal Server Error)
that prevented it from fulfilling this request.

exception

javax.servlet.ServletException: In <driver>, invalid driver class name:
"org.postgresql.Driver" at
org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImp
l.java:471) at
org.apache.jsp.ProductList$jsp._jspService(ProductList$jsp.java:474) at
org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:107) at
javax.servlet.http.HttpServlet.service(HttpServlet.java:853)
etc..............

Please help

Thanks
