After this error, you will notice a partial DB update and the data is corrupted. The Entity Bean uses automatic key generation via a Named Sequence Table.
You will not explicitly be setting <transaction-isolation><isolation-level> as TransactionSerializable for this Entity Bean. Does this option needs to be explicitly be set, or does WebLogic implicitly set it when the 'NAMED_SEQUENCE_TABLE' for automatic key generation type is used?
What is the optimal <automatic-key-generation><key-cache-size> when the table in question requires inserts from both a WebLogic-based EJB application, and a non-WebLogic standalone Java application? i.e. can both applications use the Sequence table to learn the next available key?
