Re: [JBoss-user] (no subject)
I get exactly the same behaviour with the 2.4.6.
Actually I read they solved on 3.0.
If it still there, I think it's really a bug. But it's not reported.
I hadn't the time to make a so clear report.
You should signal it as a bug submitting your code.
I'd really would like to see this solved
Bye

I am trying to test acknowledgement, non-acknowledgement, and redelivery in
JMS using JBoss3.0 Final.
Unexpected results are occuring, including strange behavior and exceptions.
I am sending and receiving from queue/testQueue, which comes default with
the JBoss setup.
The code that I am using to attempt this testing can be found at
http://www.javaworld.com/javaworld/jw-03-2002/jw-035-jms_p.html, which page
is a document describing behavior in certain JMS situations. The code can be
found below and in the attached file as well. In that page, the author gives
the following statement, which is exactly what I am trying to test:
What happens to messages that are in the session but never acknowledged?
The messages remain at the destination until they expire or forever if they
lack an expiration date. Message redelivery is not automatic, but messages
are redelivered under certain circumstances. First, calling the Session
class's recover() method recovers the session. Invoking the recover()
method causes the redelivery of all unacknowledged messages. Second, the
receiving application restarts, causing the session to restart. Restarting
the session causes all unacknowledged messages to be redelivered.
In the first case, calling the Session class's recover() method recovers
the session...causes the redelivery of all unacknowledged messages, I am
getting the following error:
javax.jms.IllegalStateException: The session is not transacted
at org.jboss.mq.SpySession.rollback(SpySession.java:353)
at org.jboss.mq.SpySession.recover(SpySession.java:388)
at Receiver.doAll(Receiver.java:39)
at ClientReceiver.main(ClientReceiver.java:10)
In the code, i use the statement:
aQC.createQueueSession(false, Session.CLIENT_ACKNOWLEDGE);
The first argument of false declares that the session is not in a
transaction. Why is rollback being called if I am not in a transaction? I
expected to re-receive all of my unacknowledged messages, but instead got
that exception. Is this a bug in JBoss, or is what I know wrong? Any help or
advice would be greatly appreciated.
In the second case, receiving application restarts, causing the session to
restart. Restarting the session causes all unacknowledged messages to be
redelivered I am getting unexpected behavior.
I stop the receiver in two different ways, one by typing the q button,
which tells the code to simply quit and exit properly, and the other by
issuing a Control-C, which of course kills the program. In either case, or
at least in one case, when the receiver starts back up, I would expect to
get some messages that hadnt yet been acknowledged when the receiver went
down. I am not getting these messages in either case. But...
When I restart JBoss with unacknowledged messages in the Queue, then start
up the reciever, the messages are being delivered. I dont quite understand
this behavior. Again, is this a bug in JBoss, or is what I know wrong? Any
help or advice would be greatly appreciated.
The Code that I am using=
import javax.naming.InitialContext;
import javax.jms.*;
public class Sender {
public static void main(String[] args) {
System.out.println(Starting...);
QueueConnectionFactory aQCF = null;
QueueConnection aQC = null;

QueueSender aSender = null;
try {
InitialContext aIC = new InitialContext();
aQCF = (QueueConnectionFactory) aIC.lookup(ConnectionFactory);
aQC = aQCF.createQueueConnection();
aQS = aQC.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
Queue aQueue = (Queue) aIC.lookup(queue/testQueue);
aSender = aQS.createSender(aQueue);
aQC.start();
for (int i = 0; i 10; i++) {
aSender.send(aQS.createObjectMessage(new Integer(i)));
}
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (aSender != null) {
aSender.close();
}
if (aQS != null) {
aQS.close();
}
if (aQC != null) {
aQC.stop();
aQC.close();
}
} catch (JMSException e) {
e.printStackTrace();
}
}
System.out.println(Ending...);

[JBoss-user] How to recovery a client from a server crash ?
Hi, I'm trying to find a way to recovery a remote client standalone application from a shutdown or a crash of my JBoss server. My Client successfully lookup for an EJB on JBoss and start to call remote methods through a classic lookup method: InitialContext iniCtx = new InitialContext(); Object tmp = iniCtx.lookup(susa_edi_gw/GatewayEDISUSA); GatewayEDISUSAHome home = (GatewayEDISUSAHome) PortableRemoteObject.narrow(tmp, GatewayEDISUSAHome.class); return home.create(); At one point I shutdown JBoss. The next remote call get an exception (of course)... Then I startup JBoss again. There is no way to successfully lookup and instantiate a remote Object. Actually I can look up objects but I get a ClassCastException when I call the: Object obj = javax.rmi.PortableRemoteObject.narrow(remoteObject, classType); I tried nearly everything: closing initialContext and initializing everything again... nothing !!! PLEASE Help Should I restart all the remote clients when my server goes down and start up again ?

[JBoss-user] JMS acknowledge() and online recover() method
Hi All, I'm using JBoss 2.4.6. and I have an external client application which reads from a queue using CLIENT_ACKNOWLEDGE session settings. If I fail to correctly process a message I don't call session.acknowledge() but I call call sesson.recover(). Unfortunately it doesn't work...Messages are resent only for a new Server startup and I cannot get live redelivery. I searched through forum's archives finding some peoples facing the same problem with any reply. Is there anybody out there using JMS with these features ? I tried also to set maxsize=1 on the jms xa resource adapter with no result. Thank you in advance Davide De Benedictis ___ Hundreds of nodes, one monster rendering program. Now that's a super model!

[JBoss-user] JDataStore JBoss 2.4.4
Hi, I'm starting experimenting Borland JDataStore with JBoss 2.4.4. I'm able to successfully start and connect to my database. Configuring JBoss.jcml file, I used as javax.sql.XADataSource implementation class, the: org.jboss.pool.jdbc.xa.wrapper.XADataSourceImpl JBoss manual suggest to use this class if the db driver doesn't support XA transactions. Given that JDataStore supports XA, I was trying to figure out which class of the Borland package is implementing this interface. Actually Borland docs are very foggy... I tried without success with: com.borland.javax.sql.JdbcConnectionPool and: com.borland.javax.sql.JdbcConnectionFactory I always get a NoSuchMethodException during Server startup. Is there someone who used the real Borland class ? Thank you in advance Davide De Benedictis ___ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user
Re: [JBoss-user] Sleeping JBoss
If you have something selected, that's your problem. It's not a JBoss problem, any java application started from a console is attached to it and if you block the console ... Just try in a simple java app. You could launch JBoss with javaw (no window) and then monitoring output by log traces.
