RE: Re[2]: [JBoss-user] JBossCMP Change Column Names in CMR
I found the solution to my problem, so i thought i'd post it in case anyone else runs into the same problem. In the jbosscmp-jdbc.xml file, for the field-name fields, instead of the cmr fields that i was specifying, you need to specify the primarykey fields for the related beans. Thus this: User-Roles User_Role Role-Belongs-To-User roles role_name User-has-multiple-Roles users user_name Becomes this: User-Roles User_Role Role-Belongs-To-User name role_name User-has-multiple-Roles userName user_name To figure it out, I used middlegen to reverse engineer my dbschema, at which point i noticed that the field-names weren't what I was doing. .peter -Original Message- From: Alex Loubyansky [mailto:[EMAIL PROTECTED]] Sent: Wednesday, July 31, 2002 11:13 AM To: Luttrell, Peter Subject: Re[2]: [JBoss-user] JBossCMP Change Column Names in CMR AFAIK, DD's are correct (with my remark).

RE: Re[2]: [JBoss-user] JBossCMP Change Column Names in CMR
Yep, here's the snipped out of my ejb-jar.xml: User-Roles User-has-multiple-Roles Many Users roles java.util.Set Role-Belongs-To-User Many Roles users java.util.Set Do I need todo something else here to make the other work? It's deployed fine and the code works perfectly. I only run into problems when i added the section in the jbosscmp-jdbc.xml to attempt to change the column-names. thanks. .peter -Original Message- From: Alex Loubyansky [mailto:[EMAIL PROTECTED]] Sent: Wednesday, July 31, 2002 11:13 AM To: Luttrell, Peter Subject: Re[2]: [JBoss-user] JBossCMP Change Column Names in CMR AFAIK, DD's are correct (with my remark).
