Problem: sending JMS message in other oc4j

I have two app server instances " OC4J (1) " and " OC4J (2) ". (snandalone 10.1.3.0.0 - Developer Preview 3 (build 041119.0001.2385)). The containers work on Windows2000 in different machines connected by the LAN.
OC4J (1):
I have J2ee of the application [app(1)] (ex. Servlet (1) or MDB (1)) in OC4J (1).
OC4J (2):
I have J2ee of the application [app(2)] deploy in OC4J (2) [included Servlet (2) or MDB (2)] . The Servlet (2), or MDB (2) - empty stub, for example code Servlet2:
package mypackage;
import javax.servlet. *;
import javax.servlet.http. *;
import java.io. PrintWriter;
import java.io. IOException;
public class Servlet1 extends HttpServlet
private static final String CONTENT_TYPE = " text/html; charset=windows-1251 ";
public void init (ServletConfig config) throws ServletException
super.init (config);
public void doGet (HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
response.setContentType (CONTENT_TYPE);
PrintWriter out = response.getWriter ();
out.println (" < html > ");
out.println (" < head > < title > Servlet1 < /title > < /head > ");
out.println (" < body > ");
out.println (" The servlet has received a GET. This is the reply. ");
out.println (" < /body > < /html > ");
out.close ();
I have configuration JMS (2) Queue in jms.xml on OC4J (2):
< jms-server...... port = "9127"
< queue name = " Demo Queue " location = "jms/demoQueue" > <description> A dummy queue </description> </queue>
< queue-connection-factory name = "jms/QueueConnectionFactory" location = "jms/QueueConnectionFactory" / >
</jms-server>
It JMS (2) Queue already is present in an OC4J 10.1.3 version.
My task:
The J2ee application (1) (ex. Servlet (1)) on OC4J (1) it is necessary to receive connection with JMS (2) (on remote OC4J (2)).
Variant 1: a code in Servlet (1):
Hashtable env=new Hashtable (8);
env.put (Context. PROVIDER_URL, " ormi: // host_OC4J (2)/app(2):23792 ");
env.put (Context. INITIAL_CONTEXT_FACTORY, " oracle.j2ee.rmi. RMIInitialContextFactory ");
env.put (Context. SECURITY_PRINCIPAL, "admin");
env.put (Context. SECURITY_CREDENTIALS, "admin");
env.put ("dedicated.connection", "true");
InitialContext ic = new InitialContext (env);
QueueConnectionFactory connectionFactory = (QueueConnectionFactory)
ic.lookup ("jms/QueueConnectionFactory");
QueueConnection connection = connectionFactory.createQueueConnection ();
connection.start ();
queueSession =
connection.createQueueSession (false, Session. AUTO_ACKNOWLEDGE);
Queue queue = (Queue) ic.lookup ("jms/demoQueue");
ic.close ();
while (true)
// - send in JMS (2)
Problem:
The Servlet (1) [in oc4j (1)] established JMS connection with oc4j (2) and begins to pass the messages [in JMS Queue (2)].
The Oc4j (2) creates some system thread for this JMS connection.
If the oc4j (1) lose network connection (example- break the cable) then created in oc4j (2) system thread is not destroyed.
Saw if this situation repeats some times that amount of the system thread in oc4j (2) is grow.
To me has answered:
In 10.1.3, the supported connection path is through the Resource Adapter (using OracleASjms.rar). The Resource Adapter offers many benefits, including the removal of stale connection threads. You have configured your application to bypass the Resource Adapter and use a direct path to OC4J JMS. You will need to create a resource mapping from your OC4J JMS admin objects (queues, topics, and connection factories) to new Resource Adapter admin objects. You can find the details of how to do this in the documentation for OC4J 10g (10.1.3) Developer Preview 3 on OTN.
You can find the link to the documentation for OC4J DP3 here:
http: // www.oracle.com/technology/tech/java/oc4 j/1013/index.html
Then I have tried Variant 2:
I need to receive connection with remote JMS (2) via generic JMS resource adapter (OracleAS Jms).
In OC4J (2), it is necessary Ñonfigure the generic JMS resource adapter (OracleAS Jms) to work with Queue "jms/demoQueue".
According to the documentation Oracle Â® Containers for J2EE Services Guide10g Release 2 (10.1.3) and example
http: // www.oracle.com/technology/tech/java/oc4 j/1013/howtos/how-to-jca-intro/doc/how- to-jca-intro.html anything it is not necessary to do.
Note that if you use the generic JMS resource adapter in an OC4J 10.1.3 version that is newer than the OC4J 10.0.3 Developer Preview 2, you can skip. In OC4J 10.1.3 it is a step is already made.
Code in Servlet (1):
Hashtable env=new Hashtable (8);
env.put (Context. PROVIDER_URL, " ormi: // host_OC4J (2) /app (2):23792 ");
env.put (Context. INITIAL_CONTEXT_FACTORY, " oracle.j2ee.rmi. RMIInitialContextFactory ");
env.put (Context. SECURITY_PRINCIPAL, "admin");
env.put (Context. SECURITY_CREDENTIALS, "admin");
env.put ("dedicated.connection", "true");
InitialContext ic = new InitialContext (env);
QueueConnectionFactory connectionFactory = (QueueConnectionFactory)
ic.lookup (" java:comp/resource/oc4jjms/jms/QueueCon nectionFactory ");
QueueConnection connection = connectionFactory.createQueueConnection ();
connection.start ();
queueSession =
connection.createQueueSession (false, Session. AUTO_ACKNOWLEDGE);
Queue queue = (Queue) ic.lookup (" java:comp/resource/oc4jjms/jms/demoQueu e ");
ic.close ();
while (true)
// - send in JMS (2)
This code works.
But!!!!!!
The problem - removal of stale connection threads in OC4J (2) instances has not solve. If the oc4j (1) lose network connection (example- break the cable) then created in oc4j (2) system thread is not destroyed.
How to me to write a code of connection with JMS (2) in Servlet (1), that Resource Adapter (in OC4J (2)) the removal of stale connection threads ???

I know the code for the jms-sending is OK (I've
tested in another application, copy of code), but i
dont know why it isn't working in this particual
Visual Web Project. It does seem like the injection
isn't taking place here; and i have no clue to
why.....where does your web.xml schema location points to ?
Injection works only with JEE 5, which means that you have to point to the right version of the servlet spec, i.e version="2.5" and web-app_2_5.xsd.

How to send JMS message from oracle to weblogic

Hello,
I am facing with a problem of sending jms message from oracle to weblogic. I am using oracle 10g and weblogic server 9.1. Here is the problem. I would like to create a trigger to send JMS message to weblogic server whenever there is an update in oracle database. So I created a java class that will send a jms message to weblogic server. But in that class I use the jndi from weblogic: weblogic.jndi.WLInitialContextFactory
when I use the loadjava utility to load that class into oracle, the status of that class is invalid though this class is working fine in eclipse with the weblogic.jar included. I was thinking because the jndi from weblogic needs the weblogic.jar in order to work, then I loaded that jar file into oracle (it took about 20 minute to load everything) and everything loaded into oracle from that jar file is invalid and missing some reference.
So my question is: how do I send a jms message from oracle to weblogic using a java class with the right jndi?
Any help will be appreciated.
Thanks
TL

It should be quite straightforward to do this. As stated you need weblogic.jar in your classpath, then use 100% standard JMS calls to publish.
Ensure that you set the following properties before getting your initial context:
java.naming.factory.initial=weblogic.jndi.WLInitialContextFactory
java.naming.provider.url=t3://node:7001 (or whatever)
this will ensure that the correct JMS implementation classes are invoked.
You can't easily (without some mucking around) build a test implementation in an AQ environment and then deploy to WebLogic because in AQ you don't tend to use JNDI lookups (unless you've implemented oracle JNDI etc) but rather use non standard factory class to create connections etc.

Is there a way to differentiate from two iPod touches that are on the same iTunes acct when using iMessage? When one child sends a message the other gets it and it says it's from our email address.

Both of my sons have iPod touches. I set them both up on my iTunes account. The problem we are having is when they are using iMessage. When one sends a message the other also receives it. The message is labeled as from my email address. Is there a way to differentiate the 2 iPods?

How to send JMS Message from a BPM Process

Hi All
I have small query regarding sending JMS Message from a bpm process. Is it possible to send JMS message from one bpm process to another bpm process.
I have a scenario in which I need to send a JMS message to a queue where another process is listening on that queue and as soon as the message is received on the queue the process instance is created.
I know how to listen for the JMS message on the queue, but I don't how to send a JMS message from a process.
Also Can I create process by sending the Notification to the process instead of a JMS message. But the process to be created is not a subprocess i.e. Can notification be send accross different processes.
Any information or example in this regard would be helpful.
Thanks in advance

Hi,
Here's one approach to sending JMS messages from an Oracle BPM process. If you're doing this just to send a message into another process, do not take this approach. It's far easier and quicker if you do this using the OOTB "send notification" logic.
These steps describe how to do this using WebLogic. The steps would be different if you're using another ap server / JMS provider.
1. Guessing you've already done this, but first expose the two required WebLogic jar files for JMS messaging as Java components in the External Resources. The two files for WebLogic are weblogic.jar and wljmsclient.jar” (located in the < WebLogic home directory > /weblogic/server/lib” directory).
AquaLogic BPM JMS Queue Listener for WebLogic 8.1
2. You've probably already done this, but add an External Resource to represent the J2EE container:
• Name: “weblogicJ2EE” - this is important and will be used in the next step
• Supported Type: “GENERIC_J2EE”
• Initial Context Factory: “weblogic.jndi.WLInitialContextFactory”
• URL: “t3://localhost:7001”
• Principal: and Credentials: whatever userid and password you defined to access theWebLogic administrative console.
3. Create the External Resource that represents the send queue configuration. In this example, I'm calling it “WebLogic Send Queue”. This is important - remember what you named it because you will use this name in the logic that sends the JMS message. This new External Resource is configured as:
• J2EE: “weblogicJ2EE” (same name as the second External Resource you created)
• Destination Type: “QUEUE”
• Lookup Name: “weblogic.examples.jms.exampleQueue”
• Connection Factory Lookup Name: “weblogic.examples.jms.QueueConnectionFactory”
4. Here's the logic to send a Message to the Queue
<pre class="jive-pre">msg as String = "Hello World"
jmsMsg as Fuego.Msg.JmsMessage
msg = "<?xml version=\"1.0\"?><Msg>" + msg + "</Msg></xml>"
jmsMsg = JmsMessage(type : JmsMessageType.TEXT)
jmsMsg.textValue = msg
sendMessage DynamicJMS
using configuration = "WebLogic Send Queue",
message = jmsMsg</pre>
Note that the “sendMessage” method uses the configuration parameter “WebLogic Send Queue”. You previously created a JMS messaging service External Resource with this name in the third step.
Again, please don't go this route if you're just using it to send notifications between processes,
Dan

Anyone have a problem sending text messages being delivered after few minutes up to five minutes?

Has anyone have a problem sending text messages and the messages won't get delivered after few minutes? From time to time I would have this problem and it's annoying. I would expect someone to receive it by then and response to my text right away. But when I look up the text it hasn't been delivered and it's in the process. I would hear that the message get delivered after few minutes? What gives? I never had a problem with my iphone 4 i think? Now with iOS 5 it let's me know whether it is delivered or not. This new feature is awesome but disappointing when I know my text hasn't been delivered right away. I'm not sure if it's the software or my iphone 4s or my carrier? anyone suggestions? Thanks!!

I have the same problem when sending iMessages.. Wasnt sure if it was apple or Sprint? But it happens VERY often and I end up having to send it as a text message instead

BusinessService which sends JMS messages to a JBoss 4.2.x server

Hi,
how do I configure my OSB so that I can send JMS messages to a JBoss server? I have added a Foreign JMS server with the appropriate initial context data and have put the jboss relevant jars into my <domain>/lib directory (javassist.jar, jbossall-client.jar, jboss-aop-jdk50.jar, jboss-messaging-client.jar, trove.jar) but I still get an error in the proxy service when it forwards the message to the business service referencing the imported JMS queues and connectionFactory. The message is:
<18.02.2010 18:00 Uhr MEZ> <Warning> <ALSB Logging> <BEA-000000> < [RouteToJboss, _onErrorHandler-1181696354513531347--39bf6a8e.126dc62f38e.-7e57, Log error, ERROR] Error occurred in flow: BEA-380002[JMSPool:169803]JNDI lookup of the JMS connection factory jboss.connectionFactory failed: javax.naming.NoInitialContextException: Cannot instantiate class: org.jnp.interfaces.NamingContextFactory [Root exception is java.lang.ClassNotFoundException: org.jnp.interfaces.NamingContextFactory]RouteToJbossrequest-pipeline>
Am I missing something?
Best regards,
Dimo
PS. I also had to put a newer log4j version in the preclasspath because jboss client seems to require verisons >= 1.2.12 and the one shipped with OSB does not cut it

There is a difference between supported and certified.
ADF was certified (meaning tested) with JBoss 4.0.4.
We didn't test with JBoss 4.2 so we don't know if it works or not.
However it is supported - meaning that if you try to deploy to 4.2 and run into issues you can open bugs with Oracle support.

Do you have MMS turn on in Settings?
Are you provisioned by your carrier to use MMS?
Lastly, give your phone carrier a call, as MMS is a carrier feature.

Send JMS Message to OJMS in a Servlet?

I'm trying to get my servlet to send a message to a JMS queue hosted by OJMS. I have had the code working with the default JMS provider (in-memory only). I can't fathom what the appropriate JNDI names are for the connection factory and queue when using the resource-provider mechanism.
The Docs suggest it's dead simple but don't give a single example to work from!
In application.xml I have:
 
 <resource-provider class="oracle.jms.OjmsContext" name="myJMS">
 <description> OJMS/AQ </description>
 <property name="datasource" value="jdbc/myDS_OCI" />
 </resource-provider>
The datasource connects to my Oracle 9i database and the schema contains a Queue Table with two queues in it. The one I want to use is called Timed_Event_Queue there.
According to the docs, I should be able to do a lookup something like
ctx.lookup("java:comp/resource/myJMS/Queues/Timed_Event_Queue")
but I can't get anything to even pretend to work!
I'm working with OC4J 9.0.4 at the moment.
Any suggestions??
Thanks,
-Dominic

Dominic,
Were you able to get the QueueConnectionFactory? I have tried this on OC4J 903 and it does work fine. Is there some error message thrown at the OC4J console?
If you want a sample code, then feel free to mail me at [email protected]
Hope this helps,

How to send JMS message from pl/SQL to jBoss

Hi all,
I need a helping. This is my problem:
There's a queue which is definitied under the Jboss. I would like send a message from pl/SQL to jBoss.
Why is't working??

thnk's,
fgy,,

You can defince a queue in Oracle, then access this queue from your Jboss application. Not sure if you need JMS, but there are some Oracle OCI functions that are certainly helpful for such a task.
You might look into further details be reading the manual on Oracle Advanced Queuing or Oracle Streams.

I have a temporary/partial solution to this problem.
As we control the application adapter that is posting messages to the MQSeries queue, we have changed the sender to put the text into the bytes message object using writeUTF rather than writeText that it was using. My reader the does a readUTF.

UnsupportedOperationException sending JMS messages

Hi everyone. I'm a bit new to OC4J, so I apologize if this is a silly question. I've got the following code:
    Hashtable environment = new Hashtable();
    environment.put("java.naming.factory.initial", "com.evermind.server.ApplicationClientInitialContextFactory");
    environment.put("java.naming.provider.url", "ormi://localhost/");
    environment.put("java.naming.security.principal", "oc4jadmin");
    environment.put("java.naming.security.credentials", "XXX");
    Context context = new InitialContext(environment);
    ConnectionFactory qcf = (ConnectionFactory)context.lookup("jms/TestConnectionFactory");
    Connection conn = qcf.createConnection();
    try
      Queue queue = (Queue)context.lookup("jms/demoQueue");
      Session qSession = conn.createSession(false, Session.AUTO_ACKNOWLEDGE);
      conn.start();
      MessageProducer producer = qSession.createProducer(queue);
      TextMessage message = qSession.createTextMessage();
      message.setText(messageText);
      producer.send(queue, "Hello to JMS!");
    finally
      conn.close();
    }And it fails with the following exception:
Exception in thread "main" java.lang.UnsupportedOperationException: MessageProducer[Oc4jJMS.Producer.matt-solnits-computer.local.db7df8:11115155f3b:-7ffb.3,Queue[Demo Queue]]: cannot send message to Queue[Demo Queue], sender has default destination.
     at com.evermind.server.jms.EvermindMessageProducer.send(EvermindMessageProducer.java:349)
     at com.evermind.server.jms.EvermindMessageProducer.send(EvermindMessageProducer.java:215)Any idea what I'm doing wrong? The JMS docs say this can happen if the MessageProducer does not have a destination, but as you can see that's not the case.
Any help would be sincerely appreciated.
-- Matt

Never mind! Just figured it out.
You can't both specify a queue in the Session.createProducer() call and in MessageProducer.send(). You have to pick one or the other.
Changing this line:
producer.send(queue, message);to:
producer.send(message);fixed it. Yay :-)
