MDB,MDB container or JMS adapter stops processing messages from JMS queue

Hi guys,
we have created a component using Enterprise Java Beans, let's say a product catalog, deployed it on a Glassfish v2 instance, and connected it to a legacy system using JMS and Sun MQ v4.1 as messaging system. The catalog component thus starts one MDB that listens on a JMS queue, let's say a queue named catalog_business_events_in, and waits for incoming messages, i.e. in our case update events. The problem is, that in general this approach works well, but sometimes the MDBs/JMS adapter stops for some reason fetching and processing messages from the JMS queue. We don't know why - no exceptions, etc.. Seems to be a Glassfish EJB container, JMS adapter or Sun MQ configuration issue. It seems to be that our component is not the problem.
The messages are compressed/uncompressed by Sun MQ automatically. We actually have 2 Sun MQ instances in clustered mode running to have some kind of failover - no HA cluster, yet. Sun MQ instances are accessed from Glassfish instances running in different Glassfish clusters - so we have a dedicated Sun MQ cluster not a Sun MQ instance per Glassfish instance. Each Glassfish instance is configured such that it knows both Sun MQ instances to allow automatic failover.
Has someone an idea, why the MDBs/ MDB container/ JMS adapter - stops processing messages? We are kind of puzzled as it happens more often now and apparently when traffic is (very) low not high!
Thanks for your help.
Cheers,
Martin

Jms adapter not polling messages from jms topic

Hi
We have a jms adapter configured in BPEL process which need to poll messages from JMS topic.Unfortunately its not polling message from JMS Topic if we add Message Selector and Durable Subscriber properties in jca file.Please find jca file content below
<adapter-config name="SyncCustomerPartyListCDHJMSConsumer" adapter="JMS Adapter" wsdlLocation="oramds:/apps/AIAMetaData/AIAComponents/ApplicationConnectorServiceLibrary/CDH/V1/ProviderABCS/SyncCustomerPartyListCDHProvABCSImpl.wsdl" xmlns="http://platform.integration.oracle/blocks/adapter/fw/metadata">
<connection-factory location="eis/jms/aia/syncCustomerParty_cf" UIJmsProvider="WLSJMS" UIConnectionName="Dev"/>
<endpoint-activation portType="Consume_Message_ptt" operation="Consume_Message">
 <activation-spec className="oracle.tip.adapter.jms.inbound.JmsConsumeActivationSpec">
 
 <property name="PayloadType" value="TextMessage"/>
 
 <property name="UseMessageListener" value="true"/>
 <property name="DestinationName" value="jms/aia/Topic.jms.COMMON.CustomerParty.PUBLISH"/>
 </activation-spec>
</endpoint-activation>
</adapter-config>
If we remove Durable subscriber and message selector properties,its able to poll messages.
Any pointer will help
thanks in advance
Baji

After changing below property in jca file.JMS adapter is able to poll messages from JMS Topic.
<property name="UseMessageListener" value="false"/>
But if i un comment below line and deploy my code again, it stop pulling the messages from topic.
<property name="DurableSubscriber" value="XYZ"/>
If i bounce the server after above change and deployment ,it will start polling the message.I am not sure why i need to restart my server after adding above property.
Thanks

Oracle JMS Adapter - Bpel Pick message from AQ based on the correlationId?

Hello,
I'm experiencing an issue during pricking the messages from AQ based on the JMSCorrelationID in Asynchronously.
I've developed asynchronous BPEL services, which will post messages in AQ (Inbound), the same service will liston response from Out queue.
Currently my service is consuming all messages, i want to consume only relevant response message based on the correlation Id.
Could you please advise me?
Regards,
Paddy.

Thanks MaShek for your replay,
During process invocation I've generated guid and set this value to JMSCorrelationID property which will set as message corrlationID, same JMSCorrelationID coming in response as well, I've set on message property same JMSCorrelationID which I set in invocation.
If same message response comes then the pick activity is working fine that means consumed message and correlation correctly, but other messages also consuming and then rejecting message. I want to restrict this.
Only relevant correlationid messages need to pick and process.
If any suggestions appreciated.
Note: I'm using Jdev11.1.15,
Regards,
Paddy

Processing messages from MQ by JMS adapter

Hi,
I have a JMS adapter which reads messages from MQ and invokes a real time service.
I am facing a problem.
Suppose after processing my 3rd message fails , i get the error
com.acta.adapter.sdk.RecoverableOperationAdapterException: JMS GET OPERATION ERROR : TIMEOUT.UNABLE TO RECEIVE RESPONSE FROM THE INVOKED DATA SERVICES SERVICE.ADAPTER OPERATION TO CONTINUE.
Now ideally the error messages should go into an error queue and the remaining messages should be processed.
But the remaining messages are also not getting processed.All subsequent messages after erroneous message also get into error q.
I have set continue after error property(In operations configuration) to True.
I am using Get operation for JMS adapter.
Any idea what could solve this issue?

MQ Adapter does not clear the rejected message from the queue

Hi All,
I'm using a MQ Adapter to fetch the message from the queue without any Backout queue configured. However, whenever there is any bad structured message found in the queue, MQ adapter rejects the message and moves the message to the rejmsg folder but does not clear it off the queue, as a result of which it keeps retrying the same hence, filling the logs and the physical memory. Somehow we do not have any backout queue configured so I can move the message to blackout queue. I have tried configuring the jca retry properties and global jca retry as well but to no avail.
- Is it not the default behaviour of MQ Adapter to remove the rejected message from the queue irrespective of Backout queue is configured or not? The same behaviour working well with the JMS and File Adapter though.
- Is there any way I can make MQ Adapter delete the message from that queue once it is rejected?

JMS adapter does not recover from error

Hello everyone,
We are noticing some strange behavior with the JMS adapter, and would like your help. We have messages coming into XI from WebSphere MQ. We have configured a Sender Comm channel (MQ_SENDER) with the appropriate JMS adapter, with a specified queue name (TEST.Q) . We have installed the appropriate MQ-JMS libraries for v6.0.
Here's the problem scenario... initially the application sending the messages to the specified queue was putting an incorrectly formatted MQRFH2 structure in the message. Predictably, this caused our comm channel to fail, and it shows up on the adapter monitor in the failed state with the message "MQJMS1050: The MQRFH2 header has an incorrect format Code: MQJMS1050". This in itself is not a problem, we realized that the application was sending a malformed message. The problem occurs when we fixed the sending application to completely strip out the MQRFH2 header altogether. When the new message is sent, the comm channel seems "stuck" on the previous error, and does not even pick up the new message from the queue. The adapter monitor continues to show the same error for the comm channel. Now when we modified the comm channel to read from a DIFFERENT queue (TEST2.Q) , the comm channel got out of the error state and is able to successfully process new messages coming into that queue. However, when we revert the comm channel back to the original queue (TEST.Q) it reverts back to the original MQJMS1050 error, and does not pick up new messages on the queue.
Any assistance would be greatly appreciated...

Hi,
1) Try to refresh the metadata
2) Check the Queue status
3) Once again check the Queue name. try to make the Sender JMS adapter inactive .save it..again make it active and save it and activate the object.
4) Refresh the Cache :
a)Start transaction SXI_CACHE.
b)From the context menu XI Runtime Cache select Start Complete Cache Refresh.
If you still face issue try this .
Many actions require to access System Landscape Directory content from the Integration Builder. To optimize performance, this content is loaded into a cache so that the System Landscape Directory does not have to be accessed directly each time that System Landscape Directory content is required.
However, this cache is not automatically updated if changes are made to the content of the System Landscape Directory. For this reason that we delete the System Landscape Directory cache if changes have been made to content in the System Landscape Directory. The cache is then filled each time that the System Landscape Directory is accessed. If we log on to the Integration Builder after we have made a change in the SLD, we do not need to delete the SLD cache.
To clear the SLD cache, from the Integration Builder main menu, choose Environment ® Delete Cache for SLD Data.
Once we have deleted the cache for SLD data, accessing objects in the SLD may take longer than usual initially.

it possible to achieve using JMS adapter or not?? what is the alternative solution ??

Hi RSR,
JMS is the better way to connect sonic MQ.below iam attaching you few points while using JMS.
1.for the JMS adapter an external driver is needed (java archive)
2.this archive is provided by the respective provider of the queuing system
3.the driver has to be deployed via SDM , see XI configuration guide for details
4.Routing rules and sender has to be specified as for any other channel in the directory
 object model
5.the message header information is determined from the appropriate sender
 agreement for the communication channel
6.the communication channel defined must be used in exactly one sender agreement
7.at least the interface name and the sender service must be qualified in the
 sender agreement ,other fields are optional
Depending on the transport protocol selected, specify the following :
8.For Sonic MQ JMS Provider :
· Java class QueueConnectionFactory
· Java class queue
· IP address or server name
· Server port
· JMS queue
9.JNDI JMS Provider Lookup
· JNDI name of QueueConnectionFactory
· JNDI name of JMS queue
· Name of JNDI Initial Context Factory
· Address of JNDI server
· JNDI users
· JNDI password with confirmation
10.
For WebSphereMQ (MQ Series) JMS Provider
· Java class QueueConnectionFactory
· Java class queue
· IP address or server name
· Queue manager name
· Channel name
· JMS queue
· Character set for non-ASCll names
· Transport/network protocol
· Target client
11.
JMS Provider Administered Objects via File
 File name of serialized object QueueConnectionFactory
 File name of serialized object Queue

How can a JMS adapter be configured in BPEL to consume messages from multiple queues ?

How can a JMS adapter be configured in BPEL to consume messages from multiple queues ?

If you want to use JMS with AQ as datastore then there is some configuration you need to do to enable this. This is outside SOA Suite per sa, e.g. no adapter required.
If you want to connect to the AQ direct then use the AQ adapter.
this blog may be of some help understand the configuration

JMS Adapter: Dynamic DestinationName for third party queue

Hello everbody!
Is there a way to make the "DestinationName" of the JMS Adapter for a third party JMS provider dynamic somehow? Like using a jndi lookup for the queue name instead for hardcoding it into the wsdl?
Thanks a lot.

Hi all,
Can any one guide me in the following requirements:
Hello,
can any one please help me in this issue:
1) JMS Name and Description
2) Parameter Values for Provider Context Factory, Connection Factory, and Default Provider URL.
Please note that the Agile PLM system fills in the fields with server-specific defaults but we must validate they are accurate.
3) User Name and Password to access the queue
1.1) JMS Name : its an queue name
Description : Queue/ Topic with JNDI name
2.1) Context factory :
what is it?
how to create it and where to create.
2.2)connection factory: connection factory name and JNDI.
2.3) how to get the Default URL from web-logic.
3.2) User name/ password : xxxxxxxxx/abcd00000. this can be set from security realms by creating the user and and assigning that user to the queue and policies.
can any one clarify my doubts in it.

How to read Java Object message from JMS Queue using JMS Adapter .

Dear All,
In my scenario i have to read a java object message from JMS Queue . I tried by using the JMS Adaper ,but i am not getting any Payload . Can any one tell me is there any special settings for JMS Adapter to read the Java Object message .
I am able to read the Message successfully thru JMS Adapter but in SXMB_MONI it is not showing any payload .
I also went in Message monitoring but i am getting this type of message in Sender JMS Adapter in Audit Log.
JMS Message ID XXXXX Message Type Null unknown.Payload can not be read and will be empty.
JMS Message ID XXXXX Payload Empty can not read.
Please Help.

Hi,
As far as i know, JMS Object Messages is not supported by XI JMS adapter.
you need to have the JMS provider to transform the message to bytes messages.
(Refer to SAP note 856346)

GUI receiving log messages from JMS

Hi,
I have three classes: GUI, EventListener and JMSListener. What I want to do is to create a login dialog. The user enters his username and password, presses the login button and waits (as this process can take a while). While waiting, he can see log messages sent via JMS.
I set up a TextListener (in my case a JMSListener) and a subscriber like it is described here: http://java.sun.com/products/jms/tutorial/1_3_1-fcs/doc/client.html#1027256.
But the JMSListener never gets any message although the connection is set up correctly (this is just a guess as no exception is thrown). I think that this is a GUI problem. Because if only the JMSListener is running, it does receive messages. Is it possible that the GUI blocks somehow?
Here is some code... First the class that holds the main method:
package de.dtnet.client.run;
import javax.swing.JFrame;
import javax.swing.SwingUtilities;
import javax.swing.UIManager;
import de.dtnet.client.gui.SWDemoGUI;
import de.dtnet.client.listener.SWDemoEventlistener;
public class SWDemoClient {
    private static SWDemoGUI swdemo = null;
     * @param args
    public static void main(String[] args) {
        swdemo = new SWDemoGUI();
        SWDemoEventlistener listener = new SWDemoEventlistener(swdemo);
        swdemo.registerEventlistener(listener);
}The code from the GUI (only the important parts):
package de.dtnet.client.gui;
import de.dtnet.client.listener.SWDemoEventlistener;
public class SWDemoGUI extends JFrame implements Serializable {
    private static final long serialVersionUID = 1L;
     * Default constructor
    public SWDemoGUI() {
        initialize();
     * Creates widget objects and puts everything together
    public void initialize() {
        // GUI with JTextPane for log messages
    public void logOK(String msg) {
        log(OK, msg);
    public void logInfo(String msg) {
        log(INFO, msg);
    public void logWarning(String msg) {
        log(WARNING, msg);
    public void logError(String msg) {
        log(ERROR, msg);
    public void log(String level, String msg) {
        StyledDocument doc = messagesTextPane.getStyledDocument();
        try {
            doc.insertString(doc.getLength(), msg + "\n", doc.getStyle(level));
        } catch (BadLocationException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        messagesTextPane.setCaretPosition(doc.getLength());
    public void registerEventlistener(SWDemoEventlistener listener) {
        loginBtn.addActionListener(listener);
        usernameTxt.addFocusListener(listener);
        passwordField.addFocusListener(listener);
}The enventlistener:

        this.gui = gui;

    private InitialContext getInitialContext() {
        // set the properties for the InitalContext

        return null;
    private void initJMS() {
        try {
            // Obtain a JNDI connection
            InitialContext jndi = getInitialContext();
            Object ref = jndi.lookup("ConnectionFactory");
            // Look up a JMS connection factory
            conFactory = (TopicConnectionFactory) PortableRemoteObject.narrow(
                    ref, TopicConnectionFactory.class);
            // Create a JMS connection
            connection = conFactory.createTopicConnection();
            // Create a JMS session objects
            topicSession = connection.createTopicSession(
                    false, Session.AUTO_ACKNOWLEDGE);
            // Look up a JMS topic
            topic = (Topic) jndi.lookup("topic/testTopic");
        } catch (NamingException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (JMSException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
    public void actionPerformed(ActionEvent e) {
        if (e.getSource() == gui.getLoginButton()) {
            // Do some authentication stuff etc.
            /* Now awaitening messages from JMS */
            subscribe(sessionID);
    public void subscribe(Long sessionID) {
        String selector = "SessionID='" + sessionID.toString() + "'";
        gui.logInfo("Selector: " + selector);
        try {
            //subscriber = topicSession.createSubscriber(topic, selector, true);
            subscriber = topicSession.createSubscriber(topic);
            JMSListener listener = new JMSListener(gui);
            subscriber.setMessageListener(listener);
            connection.start();
            gui.logOK("Verbindung zu JMS erfolgreich");
        } catch (JMSException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
}and finally the JMSListener:
ackage de.dtnet.client.listener;
public class JMSListener implements MessageListener {
    private SWDemoGUI gui = null;
    private String logLevel = null;
    private String logMessage = null;
    public JMSListener(SWDemoGUI gui) {
        super();
        this.gui = gui;
    public void onMessage(Message incomingMessage) {
        System.out.println("You got message!");
        try {
            MapMessage msg = (MapMessage) incomingMessage;
            logMessage = msg.getString("Message");
            logLevel = msg.getString("Level");
        } catch (JMSException e) {
            e.printStackTrace();
        Runnable logTopicMessage = new Runnable() {
            public void run() {
                System.out.println("Now updating the GUI");
                gui.log(logLevel, logMessage);
        SwingUtilities.invokeLater(logTopicMessage);
        System.out.println("Message fully retrieved!");
}I spent a whole day on this and I'm really becoming desperate as I can't see where the problem is and my time is running out (this is for my diploma thesis)! Does anyone of you? Please!
Thank you!

Debatching is possible when we are reading messages from JMS queue

Hi all,
If i place a message in a queue can i read the message from JMS using BPEL ( JMS Adapter ) or OSB( JMS Transport ) like batcth rather than reading the whole message in to the OSB or BPEL at the same time .
is this option is available in OSB/BPEL ??
Thanks

Recieve/Read Messages from JMS Queue through ALSB

Hi,
I have configured JMS Queue in weblogic server.
I have created Messaging Service in ALSB which sends messages in MESSAGE QUEUE.
Now Is it possinle to receive messages from JMS Queue by creating business service in Aqualogic Service bus???

Hi dear,
 
I am sending Message through Serializable Object.
 
I have JMS Proxy which gets invoked when i send message to JMs Queue. JMS Proxy then calls business service.
 
 
Business Service has two functions. One is taking String as input and one is taking Serializable Object as Input.
 
 
public void recieveString(String str) 
public void recieveObject(Trade obj) 
-------------------------------------------------- 
Now I have configured Proxy Services' Request and Response
Message Type as a "TEXT". and I am sending ObjectMessage here so what kind of change I require.
 
I also want to configure my proxy so that if JMS queue recieves TextMessage then it should invoke reciveString() function and if Object Message then vice versa.....
 
But i am not able to handle object even...
When I am sending Object Message it takes as a TextMessage.
I am getting following exception when I am sending Object Message to JMS QUEUE. Request and Response Message types are XML Schema of that object.

Mail 2.1 recently stopped downloading messages from POP server

Hi there,
I am struggling with this one.
My mail has previously been workoing no problems, through a POP server (doctors.net.uk)
Since 26/06/06 it has stopped downloading messages from the server.
I can send mail from Mail no problem and it appears on the server.
The system preferences/network is fine.
The connection Dr tells me that it can access the account no problem.
The SOCKS proxy is not enabled.
I even altered the POP account preferences to delete all messages from the server older than 1 month (previously not enabled) whic it duly did without problem.
When I click get mail, it spins, there is no error message, but no new messages appear.
I have followed this with my POP account service who insist all is fine at their end.
Any ideas?
Thanks

Try this in case the problem is that Mail is actually downloading the messages but they are being incorrectly processed by the rules:
1. Quit Mail.
2. In the Finder, go to ~/Library/Mail/.
3. Locate MessageRules.plist and move it to the Desktop. If there is a file called MessageRules.plist.backup, move it to the Desktop too. You may also see MessageSorting.plist files there; this is where Mail 1.x stored the rules, and they are no longer used by Mail 2.0, so just move them to the Trash if you see them.
4. Open Mail. As a result of removing the rules file, the junk filter will be disabled now. You may want to either tell Mail to go offline immediately after opening it, or shut down the Internet connection before opening Mail, to prevent it from downloading anything until the junk mail filter has been enabled again.
5. Go to Mail > Preferences > Junk Mail, enable junk filtering, and configure it however you wish.
6. Go online again if you went offline in step 4.
If the problem persists after doing this, then you know the rules have no bearing on it, and you may move the files on the Desktop back to the ~/Library/Mail/ folder, overwriting any files Mail may have created anew there (quit Mail first).
Note however that, if you want to test this with messages already on the server, you need to also remove the MessageUidsAlreadyDownloaded2 file again.
