Description

If you want to use a tx mgr with artemis you need to write a locator for it. Would be great to support it OOTB for well known server.

For openejb it looks like

import org.apache.activemq.artemis.service.extensions.transactions.TransactionManagerLocator;
import org.apache.openejb.OpenEJB;

import javax.transaction.TransactionManager;

public class OpenEJBTransactionManagerLocator implements TransactionManagerLocator {
    @Override
    public TransactionManager getTransactionManager() {
        return OpenEJB.getTransactionManager();
    }
}

But it is also accessible through JNDI which would fit ost of servers.

OpenJPA has a good class to lookup the transaction manager (see https://github.com/apache/openjpa/blob/trunk/openjpa-kernel/src/main/java/org/apache/openjpa/ee/AutomaticManagedRuntime.java#L55) maybe it can be used as a starting point to get impl automatic and just a flag to activate the tx mgr usage or not.

wdyt?
