JMS connect to Apache MQSeries

I am fairly new to application servers and j2ee, but at trying to setup my Weblogic server JMS services to connect to an Apache MQseries provider for point to point JMS communications.
Form reading the documentation I need to setup a bridge on my weblogic server, but does anybody know the details steps to accomplish it, when setting up the bridge is looks as if I need to specific specific java classes for the JMS provider, where are these obtained from, and what are they?
Any help in this area would be much appreciated.
Thanks

Sorry for all the confusion.
I just want to view Apache through a Web Browser from another machine.
I have set the port to 81 because 80 is taken by my router configuration.
If I type localhost:81 in the URL bar I can view my web server but if I type my ip address:81 it doesn't work.
No worries, this is just what I wanted. Try editing and adding to the bottom of the file /etc/httpd/conf/httpd.conf:
Listen YOUR_IP_ADDRESS:81
<VirtualHost IP_ADDRESS_HERE:81>
ServerName YOUR_SERVER_NAME
ServerAdmin YOUR_EMAIL_ADDRESS
DocumentRoot PATH TO YOUR HTML FILES
RewriteEngine On
RewriteRule /(.*) https://YOUR_IP_ADDRESS:433/$1
</VirtualHost>
<VirtualHost IP_ADDRESS_HERE:433>
ServerName YOUR_SERVER_NAME
ServerAdmin YOUR_EMAIL_ADDRESS
DocumentRoot PATH TO YOUR HTML FILES
TransferLog /var/log/httpd/local.access.log
ErrorLog /var/log/httpd/local.error.log
</VirtualHost>
I don't know if the 433 will be the secure part of your page but to have a cert attached to that, you will have to add a bit more to the VirtualHost related to 433 (you can read more about it at this link: http://httpd.apache.org/docs/2.0/ssl/ssl_faq.html). All the parts with CAPITAL LETTERS are parts where you will probably want to add in whatever relates to your set up.
I noticed that by default, apache hosts all of their files in /srv/http so you can place all your files in there or another location (its really up to you).
After any change to the httpd.conf file, you must restart or reload the httpd service located in /etc/rc.d/httpd
Hope this helps.
::EDIT:: What 'JuseBox' is probably a great place to check as well. If your /etc/hosts.allow or /etc/hosts.deny is in play, you want to make sure you aren't denying everything or only allowing specific things into your apache server. Good call JuseBox!

I am trying to create a custom component which makes a JMS connection and inserts messages in JMS Queue.
THe JMS server is hosted on Weblogic Application Server.
When the code runs I am getting the factory object and the queue object.
But when I try to get a connection it throws an error as pasted below.
WHen I googled the same error It has shown a simliar problem in TOmcat in sun thread
It said two jar files xerces.jar and xml-apis.jar are obsolete.
I replaced with the new version.

Problem with transacted JMS connection factory and transaction timeouts

          We encountered an interesting problem using transacted JMS connection factories.
          An EJB starts a container managed transaction and tries to validate a credit card
          before creating some information to a database for the user, in case of success
          an SMS is sent to the user via the transacted JMS queue. If the credit card authentications
          duration is about the same as the transactions timeout (in this case the default
          30 seconds) sometimes the database inserts is committed but the JMS insert is
          rollbacked. How can this be?
          If the authorization duration is much longer than 30 seconds everything works
          fine (both database and JMS inserts rollbacked), the same is true if a rollback
          is insured by calling EJBContext.setRollbackOnly(). The problem thus occurs only
          if the duration is approximately the same as the transaction timeout, it appears
          that the database insert is not timeouted but the JMS insert is. How can this
          be if they are both participating in the same transaction.
          The JMSConnectionFactory used is a Connection factory with XA-enabled. The result
          is the same also with the default "javax.jms.QueueConnectionFactory" and if we
          configure our own factory with user transactions enabled.
          Any help appreciated!

          It should not be.

          Make sure that your session is not "transacted". In other words,
          the first parameter to createSession() must be false. There is an
          unfortunate name re-use here. If a session is "transacted", it
          maintains an independent "inner transaction" independent of the
          outer transaction. From the above description, it seems unlikely
          that your application has this wrong, as you say that
          "setRollbackOnly" works - but please check anyway.
          Make sure that you are using a true XA capable driver and database
          (XA "emulation" may not suffice)
          Beyond the above, I do not see what can be going wrong. You
          may want to try posting to the transactions and jdbc newsgroups. Note
          that JMS is appears to be exhibiting the correct behavior, but the
          JDBC operation is not. The JDBC operation appears to have
          its timeout independent of the transaction monitor's timeout.

Error when creating a new JMS connection factory in GlassFish V3 b57

When I use the admin console and try to create a new JMS connection factory in GlassFish V3 b57, the operation fails with the error message
An error has occurred: Can't find ConfigModel.Property for attr -connection-validation-required on interface com.sun.enterprise.config.serverbeans.ConnectorConnectionPool
Should I better report this in the GlassFish news forum (http://forums.java.net/jive/forum.jspa?forumID=56&start=0)?
p.s. I launch the admin console from within NetBeans 6.7.1 (the server started before the IDE). WIth version b 56, creating a JMS connection factory worked fine.
Best regards,

This bug does not apear in the nightly build (b58) now so everything looks fine again.

How to find out status of JMS Connection ( connected or closed )

Is there a way to find out the status ( connected or closed ) of JMS Connection at any point of time . JMS Connection interface doesn't seem to have any isAlive( ) sort of method ?
I'm using a shared instance JMS Connection and if someone calls connection.close() on this instance the code starts flunking.

Crap isn't it! Would also be useful for creating a JMS connection pool, or for testing connections that stay open for time time and may be closed by network problems etc.
I can think of a couple of options (haven't tested them so may be flawed)
1. Extend your vendors QueueConnectionFactory object to return a decorated Connection, which adds an isAlive() method and records internally whether someone has called .close(); This could be tricky if you use JNDI to retrieve the QCF - you'll have to bind your custom QCF and remove the old one. Much easier if you use a bean factory like Spring.
2. You may be able to do this with the underlying vendor's API. If you choose this option put all the vendor specific code in a separate class and abstract it behind an interface. In future if you change to a JMS provider that does not support this feature, you can always change your isAlive() method return true no matter what;
3. Wrap the JMS sender / receiver in an Adapter class. The adapter delegates send / receive methods to the wrapped class, but if it receives a JMS exception will reconnect and try again. A second JMS Exceptions should be thrown back to the client. All your client code sees is a single send / receive method as if it was using a normal JMS sender / receiver.

Error in looking up the JMS Connection Factory

 Hi,
 I am using weblogic6.1. I created a JMS Connection factory from administrator
 console with the name QueueConnectionFactory..But when i restart the server and
 try to look up that factory its giving an NameNotFoundException...This is the
 entry of the factory in config.xml
 <JMSConnectionFactory JNDIName="QueueConnectionFactory"
 Name="QueueConnectionFactory" Targets="myserver"/>
 But if i change reapply the target server to myserver from admin console whenever
 restart the server it works fine..
 I dont know where is the problem..Can u please update me on the problem if u people
 have any idea.
 The trace of the exceptions i got is as below:
 java.rmi.RemoteException: javax.naming.NameNotFoundException: Unable to
 resolve QueueConnectionFactory. Resolved
 : '' Unresolved:'QueueConnectionFactory' ; remaining name ''
 java.rmi.RemoteException: javax.naming.NameNotFoundException: Unable to resolve
 QueueConnectionFactory. Resolved: '' Unr
 esolved:'QueueConnectionFactory' ; remaining name ''
 Thanx
 Regards,
 Narayan


 Hi Zach,
 No, I dont think ur interpretation is right..Once the entry corresponding
 to JMS Connection Factory is there in config.xml, the server should automatically
 bind it at the time of booting.. right. Why should this administrator server come
 into the picture.
 Thanx

JMS Adapter (for DI) does not allow passing username and password to JMS connection

Post Author: PLed76
CA Forum: Data Integration
JMS Adapter (for DI) does not allow passing username and password to JMS connection. It has those fields only for MSMQ. Our Production environment does not allow us to connect to JMS (we use Tibco EMS) anonymously, so it prevents us from use of Data Integrator. Is there any way to pass those params, or obtain the correct version of JMS Adapter, or obtain source codes of the JMS Adapter so we can correct them ourselves (we can send you the corrected sources back) ? Thanks in advance for any help. (PL)ed76 Renaissance Capital

Bump - Were having the same issue.
Has anyone found a way to connect to Tibco with a user/pwd?
Version 14.0.297.

HI,
We can see the JMS sender or reciver side .. in RWB .. see communicaiton channel mononitoring,., also..
We can access it through browser.. it depends upon the proocol type .. like sonic or webspeare MQ..or ...

I am also trying to bind the tib's jndi tree in wls jndi tree through a reference
object and am passing a composite name for lookup. I am getting a cannotproceedexception.
I wonder if the weblogic jndi can be federated.
anybody any ideas or pointers
thanks

Seems there is a bug in the tibco jms software.

I am also trying to bind the tib's jndi tree in wls jndi tree through
a reference
object and am passing a composite name for lookup. I am getting a cannotproceedexception.
I wonder if the weblogic jndi can be federated.
anybody any ideas or pointers

Why do the number of active JMS connections increase?

Problem
- Number of active JMS connections and current JMS messages increases until the Weblogic instances crash with an OutOfMemory exception
Setup
- Weblogic v9.2.3, Cluster with 4 Nodes
- A JMS Message is sent from a MDB in Weblogic to a distributed queue which has a member on each of the 4 Weblogic nodes. The session is created as follows session = connection.createSession(false,Session.AUTO_ACKNOWLEDGE), the message delivery mode is set programmatically to persistent and the delivery mode override of the queue setup is set to persistent too
- Standalone JMS client processes: each one is attached to all 4 nodes. Each one uses a unique JMS message selector so that we have more than one queue consumer for one queue but every message is exactly dedicated to one queue consumer. We us weblogic.jar for the clients.
- Use of Weblogic auto reconnect feature. JMS client code:
Connection connection = this.connectionFactory.createQueueConnection();
final WLConnection wlconnection = (WLConnection)connection;
wlconnection.setReconnectPolicy(JMSConstants.RECONNECT_POLICY_ALL);
wlconnection.setTotalReconnectPeriodMillis(-1);
wlconnection.setReconnectBlockingMillis(-1);
Remarks and Questions
- There are no pending JMS messages which is good
- In our setup, each JMS client is connected to all 4 nodes as the messages are not distributed to all nodes: if a message is put to Queue A but the client is only connected to Queue B, the message is NOT transfered from Queue A to Queue B. We set the parameter "Forward Delay" to 5 seconds with no effects. Is this the normal behavior?
- Not all JMS clients are visible in the Weblogic console under JMS Services -> JMS Servers -> [Server] -> Monitoring -> Active Connections. Which one are visible? Which one are not visible? There are also clients where the number of connections is not zero but stays constant; we know that as several independent clients on different hosts are started and the IP adress is visible in the Weblogic console. Why....?
- What reasons can lead to increasing connections? Is this due to client or server problems? Do we have to acknowledge the message in the onMessage(Message) method of the client JMS consumer? So far as I know, we don't have to.
- Are the increasing number of current messages due to the increasing number of JMS connections?
- May the RECONNECT_POLICY_ALL policy produce this problem?
Any hint is appreciated.

To answer the question about the forwarding of messages from one queue to another myself: As mentioned at http://forums.bea.com/thread.jspa?threadID=400000611, the forwarding for queues does only work if all queue consumers are attached to the same queue. This means that our setup is OK.
But the main question is still unanswered: why do the number of active JMS connections increase? I forgot to mention that
- all messages arrive at the clients and that no exceptions are visible in the log
- if you kill the client, the connections are still visible in the Weblogic console!?
Please help as this problem is very urgent.

Maximum JMS Connections

 Hi,
 I would like to know what is the maximum JMS connections weblogic server can
 handle anytime. And where do we set this parameter? we have a group of Message
 Listeners listening to a Queue on weblogic by opening JMS connections at the same
 time. So I was wondering how many JMS clients can Weblogic handle?? And also does
 it impact the performance of weblgic server.
 Thanx,
 Sankas


 Thanks for the information guys. It was very helful.

How WebLogic7.0 & 8.1 JMS connect to MSMQ?

          Hi Sir,
          Is it possible that i use WebLogic JMS connect to MSMQ(Microsoft)?
          If it possible, how can i configure/implement ? Do I have to create adapter class
          for MSMQ?
          Thanks
          Yos


You may be able to find a JMS wrapper for MSMQ (search
          google), in which case you can integrate using the same
          methods as for any other JMS vendor.
          Another option is to use the the WL JMS C client
          within a MS program, or even to use "ActiveJMS"
          .net wrapper from sourceforge to wrap WL JMS
          within a MS program.
          Another option is to call into MS (or vice-versa)
          using WL's JCOM feature.
          Another option is to integrate using web services -
          which is the method often pushed by MS.
          "weblogic.developer.interest.webservices"
          Another option is to consult the WLI newsgroup,
          "weblogic.integration.developer" to see if WLI
          has pre-built MSMQ adapters.

WLS 7.0.4 - JMS Connection Factory - Server Affinity - issues in log file
 We are using WLS 7.0.4 - One of JMS connection factory setting in admin console we selected "Server Affinity" options.
 We see this messages appear in Weblogic log file,

 Should we use 'load balancing option' instead of 'server affinity' ?
 Any thuoghts?
 Thanks in adv.

Can't deploy a jms connection factory

I am actually trying to do an automated deploy but I kept getting this error so I am trying to manually deploy it with the J2EE Engine Console tool. The command is:
deploy_jms_resource d:\jay\jms-factories.xml
Anybody have any ideas? At the top of the stack trace it mentions Class loading error but it is not the InitialContextFactoryImpl that is causing the problem because if I enter a totally bogus class name I get a nice ClassNotFound exception.

Hi Jay,
Which Reference guide do you mean? You find the jms-resources.xsd here: <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/55e7d51e-0e01-0010-7b84-a95ee55eadeb">Java Messaging</a>, pages 52-58.

Can't connect to Apache Server Remotely

I have set up Apache on Port 81 and I have set up port forwarding for 81 and 433 on my router but I can't seem to connect to Apache from another computer. My username is in http group.
The only way I can connect is by localhost:81
If I try ipaddress:81 I get can't establish a connection to the server.
Anyone have any ideas.
Thanks in advance!!

Sorry for all the confusion.
I just want to view Apache through a Web Browser from another machine.
I have set the port to 81 because 80 is taken by my router configuration.
If I type localhost:81 in the URL bar I can view my web server but if I type my ip address:81 it doesn't work.
No worries, this is just what I wanted. Try editing and adding to the bottom of the file /etc/httpd/conf/httpd.conf:
Listen YOUR_IP_ADDRESS:81
<VirtualHost IP_ADDRESS_HERE:81>
ServerName YOUR_SERVER_NAME
ServerAdmin YOUR_EMAIL_ADDRESS
DocumentRoot PATH TO YOUR HTML FILES
RewriteEngine On
RewriteRule /(.*) https://YOUR_IP_ADDRESS:433/$1
</VirtualHost>
<VirtualHost IP_ADDRESS_HERE:433>
ServerName YOUR_SERVER_NAME
ServerAdmin YOUR_EMAIL_ADDRESS
DocumentRoot PATH TO YOUR HTML FILES
TransferLog /var/log/httpd/local.access.log
ErrorLog /var/log/httpd/local.error.log
</VirtualHost>
I don't know if the 433 will be the secure part of your page but to have a cert attached to that, you will have to add a bit more to the VirtualHost related to 433 (you can read more about it at this link: http://httpd.apache.org/docs/2.0/ssl/ssl_faq.html). All the parts with CAPITAL LETTERS are parts where you will probably want to add in whatever relates to your set up.
I noticed that by default, apache hosts all of their files in /srv/http so you can place all your files in there or another location (its really up to you).
After any change to the httpd.conf file, you must restart or reload the httpd service located in /etc/rc.d/httpd
Hope this helps.
::EDIT:: What 'JuseBox' is probably a great place to check as well. If your /etc/hosts.allow or /etc/hosts.deny is in play, you want to make sure you aren't denying everything or only allowing specific things into your apache server. Good call JuseBox!
