Can CMP contain non-persistent fields

[alwyn]

I suspect the answer is no, but I just need to be sure.

Can CMP contain non-persistent fields?

I am thinking that the abstract class is defined with some variables and methods that access them. If possible the methods need to not be abstract in the abstract class right?

The answer is NO

If you deploy a CMP bean without setter for an CMP field you get this message:
17:04:18,664 WARN [verifier] EJB spec violation:
Bean : MyBean
Section: 10.6.2
Warning: The entity bean class must define a set accessor for each CMP field.
Info : Field: myField

The CMP fields specified in the deployment descriptor need getter and setter methods.
If you need a non CMP field just define 2 normal non abstract interface methods as getter and setter but don't mention them in the deployoment descriptor. What you do in those methods is up to you.
