As far as I know there is no direct way to use EJBs in WMQWF. You can call java classes or JSPs. Maybe you can set UPES to be an MDB (I have never done that but I donot see any reason why it will not work). Somebody with more insight into application design will eloborate on the subject. |

MQWF calls JSPs for manual Activities on a thin client, or send messages to a UPES queue for Automatic Activities. The Messages to a UPES queue can be MDBs as Venny suggested.
All MQWF cares is the data it needs to get back. How you get this data is up to you. Your JSPs can have EJBs or whatever on the backend to do the corresponding task get the result back, map it to corresponding Output container and send back to WF. So the pros and cons of EJB and J2EE are the same as in any other domain. I am not a J2EE architect so I cant help you with anything other than this.
All MQWF does is invoking an Object with appropriate data, so how this object is designed should not effect MQWF or vice versa, It only depends on your application.

in your EJB, invoke MQWF actions(login, show worklist, check in/out work items etc....) using MQWF Java APIs.
