One more try at this. I have been working on getting a DataSource to work with
DB2. At this point I am using a DataSource I configured with the admin web
page.
I have a new question. I found that I am getting an inconsistent result. I
get one of two results, without changing anything. One result is a "No
suitable driver", and the other is a "java.lang.NullPointerException". The
null pointer exception happens in the DB2Driver, which looks like Tomcat found
the driver. But the first case looks like Tomcat didn't find the driver. This
leads me to believe that there is a bug in Tomcat. Does that seem like a
logical conclusion?
>From catalina.out:
org.apache.commons.dbcp.SQLNestedException: Cannot create JDBC driver of class '

Then one of the following:
