--------------------------------------------------------------
With the help from jboss community, i am working on jbossmq migration to jboss messaging, till now the myQueue on jboss messaging is online, but at the Queue client side, i need to update current old codes for Compatibility, below is the target code pieces:
QueueMBean queueMbean = (org.jboss.mq.server.jmx.QueueMBean) ServiceLocator.getInstance().MbeanLookup("jboss.messaging.destination:name=testQueue,service=Queue", org.jboss.mq.server.jmx.QueueMBean.class);
as you know, we have no jbossmq.jar, so i don't know what is corresponding to the org.jboss.mq.server.jmx.QueueMBean in jboss messaging.
i need to use the mehods:
QueueMbean.getMaxDepth()
QueueMbean.getAllMessageCount();
depths[0] = topicMbean.getMaxDepth();
depths[1] = topicMbean.getAllMessageCount();
i tried to use org.jboss.jms.server.destination.DestinationMBean, but it only has getMaxSize() for getMaxDepth(), i can not find the method has same function to getAllMessageCount().
if i use org.jboss.jms.server.destination.QueueMBean, it has getAllMessageCount(), but does not has getMaxSize().
so what could i do?
thanks,
Emre

Hi,
I'm trying to deploy an EJB Jar that has just the following compiled classes for an MDB on JBOSS 5.1.0 :
com/
com/company/
com/company/services
com/company/services/Mail.class
com/company/services/ForwardResponse.class
I get the following error when I deploy the MDB:

[JNDI and Naming] - Service Override in JNDI
by Thomas Goettlich
Thomas Goettlich [http://community.jboss.org/people/ThomasGo] created the discussion
"Service Override in JNDI"
To view the discussion, visit: http://community.jboss.org/message/572722#572722
--------------------------------------------------------------
Hi,
before I ask my question, here's a short description of what we try to do:
We are building a platform for our projects that consists of multiple components.
Each component contains entities, data access objects and business services.
If we use those components in a project and need to extend the entities, we inherit from the base entity and the dao but not from the service.
The daos are abstract generic services, i.e. they provide generic implementations but are not annotated with @Stateless.
The services are neither generic nor abstract and thus might be extended but the logic must not be overridden.
A short example to illustrate my description:
The user component contains the following classes:
@Entity
UserEntity{ /*code here*/ }
abstract class UserDAOBean
{
doCrudStuff(Entity user) { ... }
}
@Stateless
@Local (IUserService.class)
class UserServiceBean
{
doBusinessLogic(UserEntity user) { ... }
}
The project needs to extend UserEntity and thus we have the following:
@Entity
ProjectUserEntity extends UserEntity { /*additional attributes*/ }
@Stateless
ProjectUserDAOBean extends UserDAOBean
{
@Override
doCrudStuff(ProjectUserEntity user) { /*some extended or changed code here */ }
}
This works so far.
The problem are the business services.
When I want to extend UserServiceBean, that's no problem. I then just add a ProjectUserServiceBean and call that where needed.
However, when I need to override a method - e.g. doBusinessLogic - I need other services to use the overriding service instead of the base one.
I can't change the calling services and thus have to rely on JNDI to return the correct service.
The problem is, that the JBoss 4.2.3 implemantion (that's what we're using) returns any service that implements the IUserService interface (and declares it as its local interface).
So I need UserServiceBean not to be returned by JNDI or not be registered in JNDI at all.
Finally the question: Is that possible? If so, how?
Thanks in advance.
Thomas

[JNDI and Naming] - Which HA-JMS ConnectionFactory?
by Gerald Turner
Gerald Turner [http://community.jboss.org/people/gturner] created the discussion
"Which HA-JMS ConnectionFactory?"
To view the discussion, visit: http://community.jboss.org/message/572560#572560
--------------------------------------------------------------
How should I code transacted HA-JMS sender and receiver non-EJB clients deployed within a cluster of JBoss containers?
The question is tricky because: we're using JBoss 4.2.3 in "all" configuration, but would like to upgrade to 5.1 without code changes; the clients are SAR deployments of custom MBeans; no EJB/MDB whatsoever.
Various informal documentation I've been able to scrape from the web suggests looking up the ConnectionFactory from local (non-HA) JNDI with name "java:/JmsXA" and looking up the Queue from HA-JNDI.
JmsXA is not working because evidently (and as it's name suggests) it is an XAConnectionFactory, and the code:
QueueSession session =
connection.createQueueSession(true, Session.SESSION_TRANSACTED);
…is not actually honoring the transcted/mode arguments (javadoc: "usage undefined"¹). This becomes a problem when the receiver code issues session.commit() or session.rollback() which raise the exception "TransactionInProgressException: Should not be call from a XASession".
I've searched for examples of using XASession from a non-EJB client and haven't come up with anything. I suppose I could try experimenting with session.getXAResource², but first problem faced would be how to allocate Xid objects, and then I imagine there will be failures because the underlying DataSource isn't XA (MySQL Cluster/NDB storage engine doesn't support XA).
Avoiding the XA mess and trying ConnectionFactory lookup with JNDI name "java:/ConnectionFactory" isn't working either: this object only exists on the master nodes local JNDI, it's not exported to HA-JNDI. I suppose I'll have to do remote JNDI connection to the master node? That sounds awful since I'll also need to detect and reconnect on master node failover.
Does JBoss 5.1 / JBoss Messaging "fix" any of this? I could change targets but I'm having massive interoperability problems between 4.2 and 5.1 in other applications (several clusters with total of 300+ JBoss application servers, "fork-lift" upgrade of our applications isn't
pretty).
Any advice would be much appreciated!

One thing really confused me is if I remove the commented <on> element inside <state> element "submit document", the deployment works fine. Can anyone point out what is the issue here?
The code to deploy the process is:
deploymentId = repositoryService.createDeployment()
.addResourceFromClasspath("org/jbpm/examples/state/choice/process.jpdl.xml")
.deploy();
Thank you for your time.
