Hey John,

Ugh ! ^^^^^^^^^^^^^^^^^^^^^^^^^^^
For your problem:
ejb-link is wrong, should be ejb-name of the bean so in your case
"Employer", not "org.adv.test.EmployerBean"
ejb-ref-name is OK, "ejb/Employer".
Remember that from the session bean you should lookup it via the name
"java:/comp/env/ejb/Employer"
Cheerio,
Simon
