Hi:
I am trying this in Jboss 4.0.4 and it does not work:
example:
| protected EJBContext myContext = null;
| public void setSessionContext (SessionContext ctx){
| myContext = ctx;
| }
| public void setUserData(String userId, String name, String roleId)
| throws RemoteException{
| try {
| UserLocal userLocal = UserFactoryLocal.getUser
| (userId); //Userlocal is an entity bean
| userLocal.setRoleId(roleId);
| Object object = myContext.lookup("java:/" +
myDataSourceName); // Same datasoiurce name as the bean uses, it is a local datasource
name
| Connection connection =
| ((DataSource)object).getConnection();
| connection.execute("update usuario set
| rol = '" + roleId + "' where usuario = '" + userId +
"'";
|
| connection.close();
|
| userLocal.setUserName(name); //if this set fails there is
no rollback performed to the previous execute
| }
| catch (Exception e) {
| e.printStackTrace();
| throw new EJBException(e);
| }
| }
The example as you can see is functionalitywise, bogus, but I can see that if the code
fails in setUserName then the new role appears set in the database eventhoug There is a
EJB exception thrown....
