I found the issue was that I was copying the Employee into the MDBWebClient project and when the MDBWebClient started, JBOSS tried to start the MDB in the Employee jar. The employee jar had two key component: 1) a serializable pojo and 2) the mdb. I created on jar which contain both components and this was deployed to JBOSS. I create another jar with just the serializable pojo and that jar was copied to the MDBWebClient.
Now I have everything working.
Thanks everyone for all the help.
