Renaming Backend ID problem


As the DB2 (z/OS v7) is different from the EAR’s (DB2UDBNT_V8 ), I’ve renamed the backend id myself by:

However, after this action, the table/mapping have been corrupted with message:

"Unable to create part: "

I’ve tried to change those *.tblxmis, mapxmis, but all the problem persisted.

And how could I change the table/column names "hard-coded’ in the *.class files without having java sources at hand. Actually, I could change those names, but the those names in *.classes remained unchanged. Even after all combinations of (re)building project/all, the problem persisted.

Can anyone shed some lights on me?..very frustrated.
