Investigation

When creating a Standard Job in Applications Manager using the AWJAVA Program Type you can "Select" the correct program from the list which will add the file name and extension to the "Program Name" field.

In order to properly run the .class job using AWJAVA the extension should not be part of the Program Name.

Solution

Edit the job and and remove the .class extension from the "Program Name" field in the "General" tab.
