JMS Wrappers
I'm using WL9.1 and would like to enable WebLogic JMS wrappers for my EJB. I followed the steps in e-docs, which included adding of the followings:
1) In ejb-jar.xml, I added:
<resource-ref>
<res-ref-name>MyFactory</res-ref-name>
<res-type>javax.jmx.TopicConnectionFactory</res-type>
<res-auth>Container</res-auth>
<res-sharing-scope>Shareable</res-sharing-scope>
</resource-ref>
<resource-env-ref>
<resource-env-ref-name>MyTopic</resource-env-ref-name>
<resource-env-ref-type>javax.jms.Topic</resource-env-ref-type>
</resource-env-ref>
2) In weblogic-ejb-jar.xml
<resource-description>
<res-ref-name>MyFactory</res-ref-name>
<jndi-name>MyFactory</jndi-name>
</resource-description>
<resource-env-description>
<resource-env-ref-name>MyTopic</resource-env-ref-name>
<jndi-name>MyTopic</jndi-name>
</resource-env-description>
3) I created the global MyFactory and MyTopic JNDI by adding new connection factory and topic using the console. When I did a look up for my connection factory using the name "java:comp/env/MyFactory", I received NamingException that it couldn't find the specified name. The same went with my topic. What did I do wrong?
4) I was able to look up my factory using the name "MyFactory", but I wanted to use the wrapped connection factory. What should I do?
Thanks.
First of all, wrappers are not applicable for local WL JMS server. Actually, wrappers are applicable. They implicitly provide JMS resource pooling. When wrapped JMS resources are closed, they are put into an internal pool rather than destroyed - very similar to the way JDBC connection pools work. That said, it can be simpler and more performant just to cache references to destinations, connections, sessions, producers, and consumers directly in the EJB.
>>> Second, you need to set destination-jndi-name and connection-factory-jndi-name in weblogic-ejb-jar.xml to access a remote or foreign JMS server using wrappers.
Wrappers have nothing to do with these fields. These fields are used to configure the consumers that drive the MDB.
For more information, see the EJB MDB documentation, and also see the the following FAQ:

JMS Wrappers can't cache JNDI lookups when using secured queues
Hi All!
We are working on a jms client, inside a webapp(servlets), using Weblogic 9.2 and Weblogic 10.3.
As we want to use secured queues and keep being efficient we tryed to use Weblogic JMS Wrappers, that should work according to the docs:
Enhanced Support for Using WebLogic JMS with EJBs and Servlets
http://download.oracle.com/docs/cd/E12840_01/wls/docs103/jms/j2ee.html
But we are facing a problem:
When we define a JMS Wrapper and try to cache JNDI lookups for the QueueConnectionFactory and Queue, as the docs recommend for efficiency, the connection to the queue is ignoring the user/pwd.
The JMS Wrapper is using <res-auth>Application</res-auth>.
We are creating the connection using createQueueConnection(user, pwd) from QueueConnectionFactory and after several tests it seems that the user and password are ingored unless a jndi lookup is made in the same thread, as if when there are not any thread credentials present user and password are ignored for the connection...
so the question is:
That behaviour goes against Weblogic JMS Wrapper documentation, doesn't it?
Is there then any other way to access efficiently secured queues using a servlet as a client? (iit's not an option for us to use mdbs, or ejbs).
If it helps, this seems related to this still opened spring-weblogic issue: SPR-2941 --> http://jira.springframework.org/browse/SPR-2941 and SPR-4720 --> http://jira.springframework.org/browse/SPR-4720

Quite a useful response .-)
Leaving aside the fact that weblogic behaviour with jms wrappers and secured queues seems to not be working as the docs says...
Talking about workarounds:
Both workarounds you suggest works, but as you already noted, creating a new JNDI context just to inject credentials into the threads is overkill when high performance is needed.
I also found more information about the same issue here: http://sleeplessinslc.blogspot.com/2009/04/weblogic-jms-standalone-multi-threaded.html
And he suggest the same workaround, injecting credentials
So I tried the second approach, successfully, injecting credentials into the thread using the security API.
This way, using JMS wrappers and injecting credentials into the thread we get the best performance available, caching resource using wrappers and using credentials in a somewhat efficient way.
Now the test snippet looks like this:

Using WebLogic JMS Wrappers with Spring
Hi,
I was just wondering if anyone used WebLogic JMS wrappers with Spring?
I am using WebLogic configured to have Sonic as my Foreign JNDI Provider. Weblogic provide me with specific entries on the admin console to set information such as the JNDI name of the Sonic Connection Factory. If I specify this JNDI name in the Spring config, and call getConnection() then I will get back a new connection each time.
I don't want this, I want to cache the connection (as connections are expensive in Sonic). This is where the WebLogic JMS wrappers come in, they can handle the pooling for me but the only way I can see to use them is via a resource-ref. It is possible for Spring to get a handle onto these wrappers or should I use Spring's own pooling mechanism instead?
P.S. I've also asked this question on the Spring forum
Thanks for any help
MandyMaybe you have already tried the following:
<beans xmlns:jee="http://www.springframework.org/schema/jee" ... >
<jee:jndi-lookup id="connectionFactory" jndi-name="jms.ConnectionFactory">
<jee:environment>
java.naming.factory.initial=weblogic.jndi.WLInitialContextFactory
java.naming.provider.url=t3://localhost:7001
</jee:environment>
</jee:jndi-lookup>
</beans>
an alternative is to use the JNDI template
<beans ... >
<bean id="jndiTemplate" class="org.springframework.jndi.JndiTemplate">
<property name="environment">
<props>
<prop key="java.naming.factory.initial">weblogic.jndi.WLInitialContextFactory</prop>
<prop key="java.naming.provider.url">t3://localhost:7001</prop>
</props>
</property>
</bean>
<bean id="connectionFactory" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiTemplate" ref="jndiTemplate" />
<property name="jndiName"><value>jms.ConnectionFactory</value></property>
</bean>
</beans> -
For a specific use case, we are looking at the option of using a java callout ( A POJO) in a ALSB proxy service and to write some synchronous JMS code in it. We are not sure of ALSB internals and not sure whether the java callout code will be executed from a servlet or ejb context; and even if it is we dont have a choice to specify resource reference descriptors.
In this context is, it possible to leverage the features of JMS wrappers ( especially pooled connections and sessions) using some API's in the POJO code. Or is it that we have to maintain our own pooling for these objects in the POJO ?
All documentation I have looked so far seems to indicate that this feature is available only for servlet and ejb contexts at the server side and the way to enable is to use reource reference.
Thanks,
AtheekRegardless of whether the code is running in an EJB, servlet, or even an arbitrary thread, I think you can simply lookup an arbitrary stateless session bean in JNDI and call it. The SSB can be your POJO, and can use a resource reference.
Some JNDI best practices: Remember to cache and re-use your JNDI context if possible, to cache your lookup result (JNDI lookups are relatively expensive), call context.close() when done with JNDI (to prevent a memory leak), and remember that you should not specify a URL (when no URL is specified, you get the local server or cluster name space -- which is what you want).

Hi everybody,
Is anybody successfully using remote IBM MQseries 5.3 server as
Foreign JMS in WLS 8.1sp2?
We're observing some strange behavior in this case. Here is our setup:
WLS and IBM MQ server deployed on separate boxes.
WLS version 8.1sp2 running on Windows 2000/Intel
IBM MQ version 5.3 running on Solaris/SPARC
We're using "WebSphere MQ classes for Java, version 5.303 - j5303-L030225"
and "WebSphere MQ Extended Transactional Client Feature, version 5.300 -
j5303-L030122"
MQ files added in WLS POST_CLASSPATH variable in WLS starup script.
Foreign JMS server configured in WLS via fscontext JNDI.
MDB bean deployed with Transaction attribute "Required".
Everything seems to work fine, if we're posting message to MQ queue MDB
receives it and process successfully (just print message content to the
console for now).
Problem: In WLS console, under Server->Monitoring->JTA->Monitor inflight
transactions we can constantly see one transaction enlisted for our MDB
bean with following details:
=====================================================
Transaction ID: BEA1-00DFC5EB4B7B7F28EDB9
Coordinator: mydomain+myserver
Name: JMSMessagePoller.xxx.xxx.MyMessageProcessorMdb
Status: Active
Seconds Active: 17
Resources:
weblogic.ejb20.JMSConnectionPoller.xxx.xxx.MyMessageProcessorMdb=started
Properties
(key=value):
weblogic.transaction.name=JMSMessagePoller.xxx.xxx.MyMessageProcessorMdb
=====================================================
This transaction seems to be Active for 30 seconds and then rolled back
(no error messages on WLS console displayed).On JTA statistics page in
WLS console "Total Rolled Back" counter keeps increneting with every
rollback.
Does anybody observerd similar problem? May be it's normal behaviour but
I'm kind of worrying about those transactions and constant rollback. I'd
appreciate any feedback.
Sincerely,
Dmitri Maximovich
Hi Dmitri,
The shutdown "suspend" failure has nothing to do with transactions
or JMS. It looks like the failure is due to a
java.util.ConcurrentModificationException during undeployment
which indicates a bug in WL - something is not getting
synchronized that should be.
As for MQ, their new extended client supports remote XA, which I think
is the reason for the product in the first place. Even so, I
still recommend testing to make sure that its messages
participate in transactions. (Actually, I recommend such testing
for any transactional app, including those built on WL JMS.)

How to configure MQ with WLS (JMS MQ vs Native MQ)
Hi All,
SOA Suite = 11.1.3.3
MQ Series = 6.0
Jdeveloper = 11.1.3.3
I want to read/write data to an MQ which is setup on a physical box different from Weblogic Server box. But both systems fall under the same network. I did some research on the forums to know the steps to configure MQ but ultimately got confused with the following questions in mind.
1. What is the difference between JMS MQ and Native MQ? How to determine which one to use?
2. If native MQ can be used here, what are the steps to configure Native MQ on WLS in my situation?
3. Do I need any foreign servers or message bridges to be configured?
Please provide any directions or pointers.
Regards,
Neeraj Sehga1. What is the difference between JMS MQ and Native MQ? How to determine which one to use?Native MQ refers to a proprietary api provided by IBM in multiple languages including java so that applications running on these can communicate mq. IBM also provides JMS wrappers around this native api, so that a jms client can talk to mq using JMS API. This is called MQ JMS.
2. If native MQ can be used here, what are the steps to configure Native MQ on WLS in my situation?SOA suite provides a MQ Resource Adaptor which can be used to connect to MQ. The developers of this resource adapter would have used the native api to enable the adaptor to talk to MQ, so that you dont have to worry about it. However you will need to configure the properties of your local MQ ( qmgr , q name etc). This is done in the outbound connection pool properties of the resource adaptor.
please check this blog for how to do this : http://soa-bpel-esb.blogspot.com/2009/09/configuring-mq-in-11g-soa-suite.html.
Since your MQ installation is in a remote machine you will have to configure the following properties specific to your environment - hostname, port, server connection channel, along with the queue manager name and queue name
3. Do I need any foreign servers or message bridges to be configured?Not required for your case if you are using MQ Adaptor. Since MQ also provides a JMS transport , you would have required foreign servers if you have to use JMS Adaptor instead of MQ Adaptor. Native MQ is expected to be faster than MQ JMS as it doesn't have the extra JMS layer. -
EJB3 - where to perform JMS JNDI lookups?
Hi, I was reading about how the WebLogic jms wrappers work at:
http://download.oracle.com/docs/cd/E12840_01/wls/docs103/jms/j2ee.html
and noticed this section:
"The JNDI lookups of the Connection Factory and Destination objects can be expensive in terms of performance. This is particularly true if the Destination object points to a Foreign JMS Destination MBean, and therefore, is a lookup on a non-local JNDI provider.". I am using Sonic MQ as my foreign JMS Provider hence this is of particular interest to me.
The document recommends caching these lookups in the ejbCreate() method of an EJB. I'm new to EJB3 but notice there is no concept of an ejbCreate() method there so where should I cache the lookups and how do I ensure they get re-looked up in the case of a connection failure?
Many thanks
MandyThanks very much Tom, this helps a lot. I think my confusion lay in the fact that this document talks about caching the JNDI lookups in the ejbCreate and gives the example PoolTestBean.java which uses EJB2 style code. I've made your recommended changes to my code, would you mind just casting your eye over to see if looks ok? I have chosen to cache on create of the bean rather than on first invocation as I want clients to fail on startup rather than during their processing.
Sorry about code layout, not sure how to use HTML in posts to make it verbatim..

JMS multi thread best practise
Hi,
I would like to code a JMS layer that could be accessed by
a multi thread environment (a web app)
Is there any "Connection-Pool/DAO" equivalent design
pattern for JMS ?
Form what I know, connection are Thread Safe and Sessions
are not ...
PhilippeMany J2EE providers have their own JMS facades which provide pooling - so you could just use your container's JMS wrappers.
Another option, if you are inside a Servlet Engine, is to use Jencks which provides JMS & JDBC connection pooling as well as pooling of threads & message listeners & exception handling when consuming JMS messages.
e.g. here's inbound message consumption...
http://jencks.org/Message+Driven+POJOs
and here's outbound JMS (i.e. pooling when sending JMS messages etc)
http://jencks.org/Outbound+JMS
Jencks is basically a Spring based JCA container so it takes care of all the pooling for you as well as handling message inflow & outflow and can work with XA if you need it as well as local transactions.

How to configure MQ-FTE and IBM Datapower along with PI7.1

Session Beans and TIBCO E4JMS and Weblogic JMS 8.1
Setup:-
Weblogic Server 8.1 SP2 on Linux
TIBCO E4JMS 3.1.2
I have a two Staeless Session Beans which are deployed in both sides of the cluster
- Cluster is made up of two servers(ManagedServer1 and ManagedServer2) on the
same machine. The beans have container managed transaction and trans-type set
to required. The JMS Server is on ManagedServer1. The session bean publishes 100
messages to TIBCO JMS and Weblogic JMS and calls the second bean which again publishes
100 messages to TIBCO JMS and Weblogic JMS .
The connection factories used are XAQueueConnectionFactories.
This seems to work under the following conditions:-
a) The session beans are deployed just in ManagedServer1
b) The WL load balancing scheme manages to run both the beans on ManagedServer1
c) If I don't publish onto Weblogic JMS( It runs successfully on ManagedServer1
and ManagedServer2)
It does not seems to work :-
When the The WL load balancing scheme manages to run both the beans on ManagedServer2.I
put debug statements on the beans and it seems to publish everything but fails
during the commit

Apologies in advance if this need to be posted in the JTA news group..
Any ideas?
Murali
Posting to the transaction newsgroup would probably also be helpful.
Can you post the code for the session bean so we can see how you're
enlisting Tibco in the transaction? It looks like you're using the JMS
provider wrappers from 8.1, which do the transaction enlistment for you, so
you shouldn't need to mess with JTA at all in your code. Still, something
weird is going on and it'd be nice to see exactly what your code looks like.

Remote JMS Queue in Non-Clustered Environment
We have two hosts, both running WLS 8.1, that are not clustered. We would like
to create a queue on the first and be able to read it from the second. Is this
possible? How does one go about setting this up?

Hi Paul,
This a common use case. Even user transactions
can include operations from both servers.
The remote server just looks a regular
client as far as the JMS server is concerned.
I recommend using MDBs - which can be be configured with a URL
and connection factory, messaging bridges, and/or foreign destination
wrappers. In addition, you can use the JMS resource reference
pooling feature to pool the "foreign" JMS server's resources.
For information you can start here:
http://edocs.bea.com/wls/docs81/jms/intro.html#jms_features
and here:
http://dev2dev.bea.com/technologies/jms/index.jsp
Important: As documented, for various reasons, some not
having to do with JMS, you will need to ensure the following are
true to enable "non-clustered" communication:
- all domains should be named uniquely
- all wl servers must be named uniquely
- all jms servers must be named uniquely
- all jms stores must be named uniquely

HELP with JMS message bridge to MSMQ
Can anyone offer suggestions on how to obtain/build a JMS messaging bridge to MSMQ.
I see that WL has a Messaging Bridge but only for certain foreign messaging systems.
FioranoMQ have a JMS Implementation with a bridge to MSMQ but a complete JMS implementation
seems overkill and is costly.
We already have Weblogic's JMS implementation & just want messages to appear on
a JMS Queue when they are put in a MSMQ queue. A message driven bean will then
trigger from the JMS queue.
It is rare to hear of MSMQ when it comes to messaging.
(I guess MSMQ users typically stay in MS world?)
I suggest building a minimal subset JMS wrapper. Customers
have had success with this approach with other queuing products.
If you can implement asynchronous (onMessage) then the same
wrapper can be used to plug into MDBs as well as into the bridge.
You might find that there already is open source
for these wrappers, search the web.
Take note that interop is what web-services is supposed
to be all about. You might want to investigate writing
an MSMQ app that in turn invokes a WebLogic web-service
that finally enqueues to a WL queue.
Another possibility is to write an MSMQ app that invokes
WebLogic's JMS C client to put messages into a JMS
queue. The JMS C client is due out
shortly, perhaps this week, perhaps within the next
few weeks. It will be posted to dev2dev and work
with 7.0.

JMS Foreign Provider using XAConnectionFactory for Container Managed Trans
Hello, we've been running some proof of concepts using Weblogic 10.3 with a JMS Foreign Provider attached to MQSeries 7.
We created a very simple MDB to read a message and output it's content.
We created a bindings file with a Connection Factory (without XA)
The question I have is that when I set the Transaction Management to Container and Transaction Attribute to "Required" , does Weblogic automatically look for a XAQueueConnectionFactory? We get the error below:
[EJB:011013]The Message-Driven EJB attempted to connect to the JMS connection factory with the JNDI name: OP_CF. However, the object with the JNDI name: OP_CF is not a JMS connection factory. NestedException Message is :com.ibm.mq.jms.MQQueueConnectionFactory cannot be cast to javax.jms.XAConnectionFactory>
When we set the transacation to Bean Managed or we set to Container Managed but set the attribute to "NotSupported" it works fine.
My goal is to have a MDB that has Container Managed Transactions and "Requires" Attribute, but only particpates in a local transaction and does not need the overhead of XA. It will read from a Foreign MQ manager Queue, process and then write back to the same Foreign MQ manager(different queue), so only one resource (MQ) is used.
If we set the above settings, it seems that a XAConnectionFactory is required. Is that true?-- If you do not enable the container transaction, then the MDB connection factory does not need to be an XA connection factory.
-- If the application is performing messaging operations, and wants to use locally managed transactions, then you have a variety of options. These are all standard JMS:
* Use an XA connection and XA session. Begin JTA transactions before performing JMS operations, and call commit or rollback on the JTA transaction after performing the JMS operations. For foreign vendors, you must take extra steps to ensure that the vendor enlists with the WebLogic transaction -- typically by using WebLogic resource reference wrappers.
* Use the standard JMS API "transacted session" on a non-XA session -- the transaction will be local to the session (this is extremely similar to JDBC local transactions).
* Use a non-transacted session. Sends will occur immediately. Receive messages will be acknowledged immediately for auto-ack sessions, or will not for non-ack.
-- Note that if a transaction only includes a single operation, there's no need for XA or non-transacted sessions.
-- For more information on transactions and integration, I highly recommend reading our [ Integrating Remote JMS Providers | http://download.oracle.com/docs/cd/E15523_01/web.1111/e13727/interop.htm#JMSPG553 ] FAQ. I also very highly recommend purchasing a copy of [ Professional Oracle WebLogic Server | http://www.amazon.com/Professional-Oracle-WebLogic-Server-Patrick/dp/0470484306/ref=sr_1_1?ie=UTF8&s=books&qid=1252088885&sr=8-1 ], and of course reviewing our [ JMS Information Roadmap | http://download.oracle.com/docs/cd/E15523_01/web.1111/e14529/messaging.htm#sthref23 ].
-- Finally, you may also want to consider replacing some MQ usage with WebLogic JMS. WL JMS is a heavily adopted messaging vendor, and for obvious reasons, tends to integrate especially well with the WebLogic app server.
Hope this helps,

Hi All,
I am trying to use JMS over MQ series 5.2. Can anyone tell me how to configure the Server for the JMS.
Also in mq series 5.2 JMS jars (javax.jms.* etc or its wrappers) for client programs are not available.
Can some one help me out?
Awaiting your replies....
Regards,
Lee.There are java classes for MQSeries that you can download:
http://www-4.ibm.com/software/ts/mqseries/txppacs/ma88.html
This page includes a tutorial/manual which tells you (nearly) everything you need to know about using JMS over MQSeries.

Hi,
I have several legacy java daemons that communicates with a vendor via MQ Java using MQSeries hosted at a vendor site. The daemons were poorly written and are always dying (that is when production support remembers to start them at all). :D
I'd like to rewrite the application using MDBs. Is there any way to support this without requiring the vendor to change to MQSeries JMS (i.e. set up MQSeries JNDI, configure a Java Channel, etc)? I don't have any JMS transactional requirements. I just want to move to an in-server process.
thanks,
LaphroaigIf you had the time, you could write your own version of the javax.jms.* interfaces that wraps the MQ java APIs sufficient for MDB or bridge purposes, and then register instances of the CF and destination wrappers in WebLogic's JNDi via a startup class or load-on-start servlet. I've seen various customers use this approach for non-JMS (and even non-java) queueing systems, and personally, I think this is one of the most elegant, flexible, and maintainable solutions.
Another alternative is to write your own version of a bridge. You might be able to use the "MQSeries JMS Support" code sample (meant for 6.x) as an example:

Hi guys, I will really appreciate it if someone can answer this for me. I do understand that you can use snapshots to back up file systems. But they also use up pool space when their file systems grow. So, is it necessary to create zfs snapshots even
