Resolution History
21-APR-04 13:58:48 GMT Can you easily recover from, bypass or work around the problem? = NO Does your system or application continue normally after the problem occurs? = NO Are the standard features of the system or application still available; is the loss of s ervice minor? = NO ### Detailed Problem Statement: ### Need details to connect to a JMS queue on a 10g server from another machine,but do not know all the required information, especially the URL (or JavaNamingProviderURL). Can get a connection but appears to be the wrong queue! ### What were you trying to accomplish when the problem occurred? ### OC4J JMS connection to queues on a Oracle 10g Server from a different machine running a standalone java program. ### The step-by-step actions which preceded the problem: ### Please read TAR 3656046.996 as it provides exact history. ### Has this ever worked? ### No ### Can you reproduce the problem at will? ### Yes ### Reproducible on other platforms, systems, environments? ### No ### Known recent changes to your computer environment: ### no Contact me via : E-mail -> Michael.Wever@bokklubbene.no 21-APR-04 14:04:59 GMT New info : The client and the server do not appear to be accessing the same oc4j jms queue! <br/> I cannot get any messages across the two program?!

Yes. Is this a standalone instance of ias or is associated with an infrastructure? Infrastructure. (Database listeners, and another server running portal application). Does this machine have a static ip address? Yes. 21-APR-04 14:15:50 GMT New info : Please do not ask me to try ODC. It does not work on linux machines. 21-APR-04 14:47:41 GMT This seems to be a spin off from 3656046.996 21-APR-04 14:48:50 GMT Hi Michael, Thank you for using MetaLink. We are currently reviewing/researching the situation and will update the SR / call you as soon as we have relevant in formation. Thank you for your patience. Best Regards, Prag Oracle Support Services STATUS ======= @WIP -- Work In Progress 21-APR-04 16:45:59 GMT Hi Michael, It is not possible to have two Queues with the same name. Can you read the messages queued in the server from server itself rather than from cli ent. This will prove in the first place if message is queued. If not we need to investigate this. Secondly do you have any jms.xml file on the client side or any other configuration file which has queueConnectionfactory details. What you are doing is pretty much the same as the demo which is sending & receiving mess ages from standalone java code. It is only that you are connecting to a differe nt server & this could be accomplished. Regards, Prag EMEA IP Support 21-APR-04 16:46:12 GMT Email Update button has been pressed: Sending email to Michael.Wever@bokklubbene .no. 21-APR-04 16:54:55 GMT New info : There are messages in the queues on the server, and they can be browsed from the server. The queues are called "jms/SmsInQueue" and "jms/SmsOutQueue". From the client connection seems to occur without problems, but there is no crossover of messages. That is, it is like there are separate queues and the client can only browse the messages it itself puts into the queues, and the server can only browse messages it places into the queues. 21-APR-04 16:59:48 GMT New info : there is a jms.xml (j2ee/home/config/) under the standalone oc4j on the client machine but it does not describe the specified queues, it is the default file that comes from oracle. 21-APR-04 17:21:57 GMT New info : I am available 24-7 to help prioritise this TAR. It is quite serious and has already set the project's deadline back 2 months. 22-APR-04 08:20:41 GMT ok, thanks for the update, investigating.. Will escalate this RS as the original one was escalated & this SR is a branch off it 22-APR-04 11:42:48 GMT New info : I submitted the client program's log files to the third party company and recieved the following reply: The exception below signals that you cannot connect to your jms server. There should be NO exceptions. The connection fails actually when it does the naming lookup on the queues, not when trying to connect to the actual queues. At least that's what seems to be the case to me :) Lars Ove The exception was: 15:04.52.484 21.04.2004 SEVERE IF-HANDLER Exception occurred during connection: Lookup error: java.net.ConnectException: Connection timed out; nested exception is: <LF><TAB>java.net.ConnectException: Connection timed outjavax.naming.NamingException: Lookup error: java.net.ConnectException: Connection timed out; nested exception is: <LF><TAB>java.net.ConnectException: Connection timed out [Root exception is java.net.ConnectException: Connection timed out] javax.naming.NamingException: Lookup error: java.net.ConnectException: Connection timed out; nested exception is: java.net.ConnectException: Connection timed out [Root exception is java.net.ConnectException: Connection timed out] at com.evermind.server.rmi.RMIContext.lookup(RMIContext.java:153) at com.evermind.naming.FilterContext.lookup(FilterContext.java:138) at com.evermind.naming.SubFilterContext.lookup(SubFilterContext.java:55) at javax.naming.InitialContext.lookup(InitialContext.java:347) at com.datek.cpas5.interfaceHandler.JMSInterfaceHandler.initializeConnectio n(JMSInterfaceHandler.java:388) at com.datek.cpas5.interfaceHandler.JMSInterfaceHandler.access$200(JMSInter faceHandler.java:36) at com.datek.cpas5.interfaceHandler.JMSInterfaceHandler$ConnectionWorker.ma keConnection(JMSInterfaceHandler.java:780) at com.datek.cpas5.interfaceHandler.JMSInterfaceHandler$ConnectionWorker.ru n(JMSInterfaceHandler.java:742) at java.lang.Thread.run(Thread.java:534) Caused by: java.net.ConnectException: Connection timed out at java.net.PlainSocketImpl.socketConnect(Native Method) at java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:305) at java.net.PlainSocketImpl.connectToAddress(PlainSocketImpl.java:171) at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:158) at java.net.Socket.connect(Socket.java:452) at java.net.Socket.connect(Socket.java:402) at java.net.Socket.<init>(Socket.java:309) at java.net.Socket.<init>(Socket.java:153) at Text continued in next action... 22-APR-04 11:43:51 GMT Text continued from previous action... com.evermind.server.rmi.RMIConnection.connect(RMIConnection.java:2209) at com.evermind.server.rmi.RMIConnection.lookup(RMIConnection.java:1685) at com.evermind.server.rmi.RMIServer.lookup(RMIServer.java:727) at com.evermind.server.rmi.RMIContext.lookup(RMIContext.java:134) ... 8 more 22-APR-04 15:33:39 GMT Hi Michael, Please provide your contact no for the evening.

I will provide the update here as to where the testcase can be downloaded from and what steps are needed to use. Regards, Andy @WIP 22-APR-04 18:20:05 GMT Email Update button has been pressed: Sending email to Michael.Wever@bokklubbene .no. 23-APR-04 03:49:24 GMT Hi, Since you are using a third party client which we are unfamiliar with, I have produced a test case to validate for my self that the functionality is worki ng correctly. I have uploaded this test case to the following anonymous FTP loca tion: ftp://oracle-ftp.us.oracle.com/server/outgoing/3682720.994/OJMS_CLIENT_SERVER.zip The zip file contains a self contained workspace for JDeveloper. It will unpack to it's own directory "OJMS_CLIENT_SERVER". If you are a user of our JDeveloper 9.0.5.1 product (freely downloadable from Oracle Technology Network) then you can open up the OJMS_CLIENT_SERVER.jws in JDeveloper. If you are not a user of JDeveloper, then the "OJMS_CLIENT_SERVER_APP/deploy" folder contains a pre-built EAR file, that you should be able to deploy without making any changes . For deployment you can use Enterprise Manager or "dcmctl" command line: dcmctl deployApplication -a OJMS_CLIENT_SERVER_APP -f OJMS_CLIENT_SERVER_APP.ear -co <OC4J Instance> -v -d Before deploying, you will need to define the following queue in the $ORACLE_HOME/j2ee/<instance name>/config/jms.xml file: <queue name="OJMS_CLIENT_SERVER_Q" location="jms/OJMS_CLIENT_SERVER_Q"> <description>QUEUE FOR OJMS_CLIENT_SERVER_APP</description> </queue> This can be done at the top of the file, immediately inside the <jms-server> tag. In case you are not yet familiar with the Centralized Management Features of OC4J, after changing configuration files in the file system you would need to propagate the changed file back into the DCM repository: % dcmctl updateConfig -co <OC4J Instance Name> -v -d You should then restart the modified OC4J instance to pick up the changes: % opmnctl stopproc process-type=<OC4J Instance Name> % opmnctl startproc process-type=<OC4J Instance Name> After this, you should be able to reach the following URL's: (a) http://server:port/jmstest/browseQueue - browses the queue without removing items from it (b) http://server:port/jmstest/submitMessage - is a servlet whose doGet() method displays a form that allows you to enter an ID property and text for a JMS message. The form submits (via POST) back to the same servlet, whos doPost() method JMS directly to submit the J MS Message (c) http://server:port/jmstest/submitMessageToEJB - same as above except the doPost() method retrieves a local reference to a Stateless Session B ean (SLSB) facade which creates the JMS Message. So you can post a few message and browser them server side. Now, to match up with your concerns about the client not seeing the same queue contents, I have written a remote client. Again, if you use JDeveloper it it really simple to run it by right clicking on the "JMSQueueConsumer.java" in the "CLIENT" project. Then you can click on "run". Before doing so, you will need to update "jndi.properties" to fit your location. If you do not use JDeveloper, you can still use the precompiled class file "JMS QueueConsumer.class" but will need to setup your environment to run it (same requirements as in the preceeding service request). You should ensure that the clas spath picks up the "jndi.properties", "application-client.xml" and "orion-applic ation-client.xml" files. The client will run until interrupted and for each message that gets placed on the queue it will consume it and print it out to stdout , for example: JMSQueueConsumer::onMessage()::CALLED; TIME=22-Apr-2004@11:43:21:966 JMSQueueConsumer::################ JMSQueueConsumer::### JMSQueueConsumer::### MESSAGE JMSQueueConsumer::### ======= JMSQueueConsumer::### ID: 1 JMSQueueConsumer::### SUBMIT_TIME: 22-Apr-2004@11:39:37:321 JMSQueueConsumer::### TEXT: Test OJMS Message JMSQueueConsumer::### JMSQueueConsumer::################ You can mix and match creating messages with the servlet and browsing. This can be done while the client is running (if so, the browse serv let won;t get a chance to catch anything in the queue). I would like you to use this as a test harness to confirm that your environment works the same as ours. 23-APR-04 04:33:42 GMT Email Update button has been pressed: Sending email to Michael.Wever@bokklubbene .no. 23-APR-04 12:38:54 GMT Hello, Also, based on my exposure to your other service request and my perception that your are coming to grips with the flexibility of OC4J when running as a component of Application Server (as compared to the simpler "standalone" OC4J t hat is installed by unzipping a file), I believe it may help you to read: 245805.1 BEST PRACTICES FOR MANAGING OC4J DYNAMIC PORT ALLOCATIONS VIA OPMN I am still curious if you have multiple JVM's running for the same OC4J instance, whic h would be the only reason that you would need to use the "opmn:ormi" lookup syn tax. In the event that there are multiple OC4J instances, each instance would (u nless configured appropriately) have it's own queue. I just want to rule out any complications of this nature that might explain why you can browse the queues o n the server but the client does not see the messages. Also, I am a little confused by your description of the problem (that you can see the message queue on t he server, but not from the remote client) and the view of your third party supp ort team, that you are not able to connect to the server, which seem to be contr adicting to some extent. As we did in the other service request, I would recommend as a first step simplifying by removing "opmn:ormi". You should be able to do this by using the information in 245805.1 to control the port assignments. To show the current port assignments for your OC4J instance, you can even use: % $ORACLE_HOME/opmn/bin/opmnctl status -l which will list rows similar to: OC4J | ANDY | 27232 | Alive | 512229555 | 109864 | 9:52:45 | jms:5067,rmi:5034,ajp:5000 Then, change your third party configuration from: <JavaNamingProviderURL>opmn:ormi://samboapp-1.bokklubbene.no:6003:home</JavaNamingProviderURL> to using the rmi port: <JavaNamingProviderURL>ormi://samboapp-1.bokklubbene.no:5034:home</JavaNamingProviderURL> Regards, Andy Parkman 23-APR-04 12:52:19 GMT Email Update button has been pressed: Sending email to Michael.Wever@bokklubbene .no. 23-APR-04 14:59:13 GMT I tried to reach you on the contact details provided: > New info : Work phone: +47 2202 2067 > After Hours: +47 92221689 but did not receive a reply on the work number and did not understand the answer message (German) on the after hours number.
