Examples with Transaction javax.transaction.Transaction used on opensource projects

Example 81 with Transaction

use of javax.transaction.Transaction in project hazelcast by hazelcast.

the class ClientXATest method testRollbackOnTimeout.

@Test
public void testRollbackOnTimeout() throws Exception {
    Hazelcast.newHazelcastInstance();
    HazelcastInstance client = HazelcastClient.newHazelcastClient();
    String name = randomString();
    IQueue<Object> queue = client.getQueue(name);
    queue.offer(randomString());
    HazelcastXAResource xaResource = client.getXAResource();
    tm.setTransactionTimeout(3);
    tm.begin();
    Transaction transaction = tm.getTransaction();
    transaction.enlistResource(xaResource);
    TransactionContext context = xaResource.getTransactionContext();
    try {
        context.getQueue(name).take();

        tm.commit();
        fail();
    } catch (RollbackException ignored) {
    // Transaction already rolled-back due to timeout, no need to call tm.rollback explicitly
    }
