Hello,
I have the following stateless session bean:

@Stateless
public class UtilityBean implements UtilityRemote
{
 @PersistenceContext(unitName="performance_persistence_unit")
 EntityManager manager;

 @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
 private void deleteStockItems()
 {
 System.out.println("Start deleting StockItems");
 Query qStockItem = manager.createQuery("delete from StockItem");
 int retValue = qStockItem.executeUpdate();
 System.out.println("Deleted "+retValue+" rows.");
 System.out.println("End deleting StockItems");
 }

 .., here are similar methods for other entities ...

 @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
 public void deleteAllData()
 {
 System.out.println("Start deleting all data in database");
 deleteStockItems();
 deleteOrderItems();
 deleteOrders();
 deleteCompanies();
 deleteCountries();
 System.out.println("End deleting all data in database");
 }

 @Remove
 public void free()
 {
 }

When I invoke deleteAllData() method from client, I get after 5 minutes warning (only part):
WARN [org.jboss.tm.TransactionImpl] Transaction timed out. status=STATUS_ACTIVE

And when method ends then I obtain exception (only part):
ERROR [org.hibernate.util.JDBCExceptionReporter] Transaction is not active

Solution - change in jboss-service.xml file section of "TransactionManagerService" the value of "TransactionTimeout" from 300 to 1200.
It means prolong timeout from 5 minutes to 20 minutes.

Is this correct way? Does exist other solution (for example manually set timeout per sessionbean / method) ?

Thank you very much,
Leonell
