I am using Oracle JDeveloper 9.0.5.1 (Build 1605).
When I try to run the application, data base access fails with the following:

hosts due to exception: java.lang.NullPointerException

However, debugging the servlet (without any breakpoints) works fine.
I cannot find any explanation for this. All parameters passed to getConnection are correct. Received on Tue Jun 08 2004 - 14:17:13 CEST
