Hi There!
I am also experiencing some problems while trying the BasicDB Example. I have been reading the previous posts to that subject, but couldn’t find a solution.
May be you can tell me where I should start searching for the mistake, when you look on the error message of Tomcat:

—————————————-
HTTP Status 500 –

type Exception report

message

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

exception

note The full stack trace of the root cause is available in the Apache Tomcat/5.0.28 logs.

Thanks in advance.

java.lang.NullPointerException

What is happening at line 56 in SessionFactory? Do you need to check for a null here and do something if it is null?

Sorry for this post!
I forgott to copy the JDBC-driver to Tomcats classloader path.
Now it runs nice 😀

Glad it’s working, thank you for the followup.
