1.0 Known problems

1.1 Restriction for "meet in the middle" mapping to multiple tables

In a "meet in the middle" mapping scenario where you are mapping an EJB to multiple tables, the tool only supports mapping underlying tables that are connected by "primary key to primary key" foreign keys. These foreign keys can be arranged either as a daisy-chain from leaf tables to primary table or with the foreign keys of all leaf tables pointing to the primary table.

The tool does not support any other arrangement of foreign keys between the tables, and the tool does not warn you that other arrangements will not be mapped properly. This problem exists both for root/leaf inheritance mappings and for a single EJB mapped to multiple tables.

1.2 WSAD terminates on regeneration of EJB mapping while WebSphere Test Environment running

The WebSphere Studio JVM may prematurely terminate while regenerating EBJ mappings for CMP attributes while the application is running on the 5.1 WebSphere Test Environment. To work around the problem shut down the test environment prior to changing and regenerating CMP mappings.
