I'm going to ask this one again, because I really can't seem to get it sorted. If I call the JNDI MySQL HOWTO example from a fully-qualified domain name URL, I get a java SQLException.
Any ideas of where to even begin to shoot this one? Greg At 12:08 PM 10/25/02 -0400, Greg Bullough wrote:

But throws a java.sql.SQLException: Cannot load JDBC driver class 'null'
if I call it from a different machine in the same domain via a fully-
qualified URL of the form http://myexternalname.mydomain.com:8080/DBTest?DBtest.jsp
Adding a bit of debug trace info shows me that it happened on the
ds.GetConnection() after the ctxLookup has set ds to some non-null value.
Any insights as to why the fully-qualified URL on the page should
make a difference this deep into the code? I'm thinking some sort
of security settings. Once again, the configuration and code is
basically verbatim copied from the HOWTO. Tomcat 4.1.12-LE
