ApplicationException and rollback

[Kiril Nugmanov]

Hi all,

I'm trying to execute following code:

Application exception with rollback set to true

import javax.ejb.ApplicationException;

@ApplicationException(rollback = true)
public class Test extends Exception {
    public Test(String message) {
        super("Test Exception" + message);
    }
}

Bean with method that catches application exception

import javax.ejb.*;
import javax.annotation.Resource;
import java.util.logging.Logger;

@Stateless
@Local(Edas.class)
public class EdasDao implements Edas {
    private static final Logger log = Logger.getLogger(EdasDao.class.toString());
   
    @Resource
    private EJBContext ejbContext;

    @TransactionAttribute(TransactionAttributeType.MANDATORY)
    private void megaException() throws Test {
        throw new Test("asdasd");
    }


    public void thowException() {
        try {
            megaException();
        } catch (Test test) {
            log.info("status "+ejbContext.getRollbackOnly());
        }


    }
}

After the thowException() method is executed, the status is returned as FALSE

#|2010-05-14T08:34:55.390+0300|INFO|sun-appserver2.1|class lt.emc.ejb.EdasDao|_ThreadID=20;_ThreadName=httpSSLWorkerThread-8080-1;|status false|#

But as I understand the transaction management - transaction should be marked as rollback. Am I correct

Try to call the megaException() method from another bean. I don't think that the container is given a chance to rollback the transaction in your case.

Hi Christophe,

Tried as You said and obtained following results in log after calling megaException() from another bean:

#|2010-05-14T09:48:54.609+0300|INFO|sun-appserver2.1|class lt.emc.ejb.EeBean|_ThreadID=20;_ThreadName=httpSSLWorkerThread-8080-1;|EeBean before false|#
#|2010-05-14T09:48:54.609+0300|INFO|sun-appserver2.1|class lt.emc.ejb.EeBean|_ThreadID=20;_ThreadName=httpSSLWorkerThread-8080-1;|EeBean after true#]

According then it seems that I can't mark transaction as rollback if methods are from the same bean. It's strange or am I missing something

[Christophe Verré]

I don't find it strange. You're calling a method from the same bean, and catching the exception. The container cannot do anything in that case. You'd have to set the transaction for rollback yourself. If your thowException would also throw the exception, the container would get it, mark the transaction to be rolled back, and rethrow the exception to the client.

Thanks for clearing out.
