Java EE (Java Enterprise Edition) General Discussion

Hi,

I was wondering if you could help me with a problem I am having deploying a multi-tiered application. Currently I am deploying a sub-set of the entire application as a test. I have a EJB representing a warehouse clerk and one representing a sales representative. Each EJBs has two public data members - username and password which are populated for the database. I am using container managed persistance. I have managed to deploy the two EJBs and a web component which comprises a servlet and a static html page. The servlet takes the type of user - warehouse clerk or sales representative, and the username and password entered. Depending on the user type the appropriate EJB is looked-up and the actual instance is located using a finder method.

However, when I enter the username and password details into the form on the static HTML page, select the user type and then submit the details I get the following error message:

=========================================================================
Below is the line of my LoginServlet class which is referred to in the stack trace - Object object = context.lookup
( "java:comp/env/ejb/WarehouseClerk" );

=========================================================================
Finally I have given the earlier deployment messages below: -

Any help would be most appreciated.
