Your JDBC code may throw the following exception:
"The coordinator has rolled back the transaction.No further JDBC access is permitted within this transaction." The WebLogic JTS JDBC driver throws this exception when the present JDBC connection transaction rolls back prior to or throughout the JDBC call. This exception shows that the transaction in which the JDBC connection was participating was rolled back at some point prior to or through the JDBC call.The rollback may have happened in an previous EJB invoke that was part of the transaction, or the rollback may have happened because the transaction timed out.
