the disadvantage that we have is that the transaction this not doing neither commit, nor rollback, nor displays exceptions. the states of the transaction are 0 after initiates and 6 after the commit and rollback. when we see in the data bases non entrance the data even though does not appear any exception. the data bases that we used are postgreSQL, and the server is JBoss 4.0.2
