===== 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)

Is it possible to lookup and use UserTransaction from a remote-client as

Or is it planned for further release?
In AS 7, you can have a connection to more than one server at once.
Thus you have to specify which server node you want to talk to. The
method you want is
org.jboss.ejb.client.EJBClient#getUserTransaction(String), where the
argument is the node name. Note that your connection must already be
established at this point.
We do not presently have a way to pull a UserTransaction out of JNDI,
though that could be considered for an enhancement.
