According to previous article about SAP JCo 2.1.7 and Apache Tomcat, I later got some trouble to run real applications based on SAP JCo APIs. I'm sure that the code is absolutely correct. Anyway, I always got NullPointerException. There are several thread talking about this issue.

The easiest way to solve this problem is to use SAP JCo 2.0.12. Go to get it from http://service.sap.com/connectors.
