Hi,

We have a problem when we want to add a new many to many relationshipt to a table (or EJB). I think we are missing one step in the precedure, this is what we are doing:
- create the table in the xe.dbm file with all the fields and then we add the two FK that conform the PK.
- Then we generate a new EJB with all the CMP fields and an id as a key for the EJB
- Add the relationships with the two EJBs.
- Once they are created, we select those two FK, and mark them as keys.
- remove the id field.
- then we make the mapping on the Map.mapxmi file

But then when we want to generate the RMI code with the "prepare for deployment" we get a "Error generating Create query from bean Mensaje (Abstract schema name=Mensaje)" the bean Mensaje is Ok, because we could make the prepare for deployment before adding this EJB. And the error in the Problems view is: An error has occured running EJBQL Validation.Check the error log.

Can anyone tell me how to correct this?
 
It is sorta covered in the JavaRanch Style Guide.
