Goal

The problem is encountered when running a servlet.  The servlet will run fine until a null pointer exception is thrown.
 The servlet is taking parameters from the weblogic.properties file via the ServletConfig object.

When the servlet fails the following error is given:

<ServletContext-General> Servlet failed with Exception
java.lang.NullPointerException:
