Description:
MysqlXaDataSource class is missing in the jar file.  This is needed in order for user transaction to rollback.

How to repeat:
open the jar file and it can be noticed that the MysqlXaDataSource is not inside.

MM.MySQL supported 'emulated' XA transacations (hence the MySQLXADataSource implementation), but this feature was removed for 3.0 onwards due to the fact that it didn't work well. Connector/J will have XA support once the MySQL server itself supports this functionality.

In the meantime, you should use whatever XA wrappers your application server provides (BEA and JBoss provide XA wrappers for non-XA databases) to acheive the same functionality, but realize that you can have un-recoverable heuristic failures using these wrappers.
