I have just configured a mysql database to work with jboss. It seems to work correct, a call to findByPrimaryKey() on a CMP bean works oke. But when i try to create a CMP bean from his home interface (this is actual a insert record into db) a really long exception is trown:

Is this exception thrown cause mysql does not support transactions?
D:\mysql\bin>mysql --version
mysql Ver 11.15 Distrib 3.23.38, for Win95/Win98 (i32)
