Part of the problem is this issue that we just discovered:
https://issues.jboss.org/browse/AS7-4092, where empty transactions cannot be committed or
rolled back.
I am just testing a fix now.

===== Regarding node-name. =====
In standalone I supposed it is the name of jboss-ejb-client.properties
remote.connection.default.host=localhost
But I have to set it by -Djboss.node.name=<>.
??? it is not possible to add a system-property to the standalone.xml for that, or do I
something wrong with the system-property element in configuration???
??? What is the name in domain mode? Is the <server name="" ...>
attribute for each defined server used???
??? Is it possible to see the node name with the management console???
The section for remote invoking EJB's note that a node name must be set unique, but I
did not see any problem if I start two instances (same machine) without jboss.node.name?
Is here a default created?
==== UserTransaction =====
If I do this in my client:
{code}
1: UserTransaction uTx = EJBClient.getUserTransaction("Wolf");
2: LOG.debug("UserTransaction ="+uTx);
3: uTx.begin();
4: LOG.debug("Tx.begin() ok");
5: bmtSession.checkTransaction(); // call a SLSB to use Tx
6: uTx.commit();
LOG.debug("Tx.commit() ok");
{code}
Line 1 and 3 works nevertheless whether there is a server (with or without a correct
node.name) or not. The line 5: will fail 'No EJB receiver with 'node.name'
If I remove getUserTransaction I can execute the code nevertheless whether a node name is
set or not.
??? So I suppose the getUTx will attach the next EJB call to that server ???
If a server is available the commit will fail (also the EJB checkTransaction show the
TxState=6 (NO-Tx)
