JMS Question
I've inherited some code and it doesn't look complete, and I'm not even sure that it will work- at least with Orion. So... We've got multiple servers- some are always connected, some are only connected periodically, some are only connected when the sysadmin physically performs some task and then only for a limited time. The goal is that we'd like to be able to "push" a message to a specific server through user control. We know all of the addresses of all the possible machines ahead of time, so having the user enter a JNDI name is not an issue, and I can setup a servlet/whatever to provide this selection process. The previous programmer on this project thought that JMS would be a good solution for this, with each server being a JMS server. However I'm not certain that this is going to work-- at least not with Orion out of the box. Current Basic flow: Client creates a temporary queue for message responses Client selects a particular machine (i.e. JNDI name) We write to a Queue on the remote server, setting reply to to be the temp queue on the "local" JMS server. Remote system processes message and sends back a response to the temp queue. Is the above in any way, shape, or form feasible with Orion? I've been doing a crash course on JMS (thanks to O'reilly), but after reading the books and the Orion docs, I'm thinking that this may be better suited for a servlet based approach. Any help is appreciated! robert hedin NDS Systems, Inc.
RE: JMS question: How to connect to a remote host
In your orion/config/jms.xml, change host="localhost" to a public IP, such as: Hi folks, I'm just tring out the JMSChat sample. I'm want to run it from another host as the orion server is running. But this seems not possible since I got the following error message "Communication error: Unable to connect to JMSServer (localhost/127.0.0.1:9127): Connection refused:" So is there a Property or method which I can use to connect to another host.

Hani, >Try again, the mailing list software was down for a couple of days last >week(See Jay, other people lost emails too!) > >Hani I don't think this explains why Karl failed to check out the license violation I reported, to respond to my request for an update on that, or why my three attempts (June 7, 8, and 10) to respond to Karl on the "Oracle deal" have not shown up. Would you agree that it's possible for both intentional and unintentional blocking to occur? Threads like "Orion Team Needs New List Software" (Mar 14), almost 3 months ago, apparently have not resulted in a working list. If Orion is distributed with a demo news server, how can they not be able to create one that works on their own? They said they would hire additional staff, but they didn't. If the list server is really the problem, then wouldn't additional staff or a volunteer from the interest group could have solved this long ago? Regarding my sanity and my response to Jeff Schnitzer, I was very pissed off and I forgot that what is commonly known in the intelligence community may seem "over the top" to private citizens. Again, I apologize to the group and ask forgiveness for losing my temper. I do not believe that Karl and Magnus are part of some ridiculous conspiracy. I think they've made some fabulous business decisions, but also some incredibly stupid ones (like not fulfilling their pledge to hire more staff or supporting me when I reported a license violation). The real purpose of my original message was to get them to acknowledge the free labor they've gotten from the orion community, and to have them encourage Oracle to tap into that (paid, not for free). What's wrong with that? I confess that I also wanted some vindication for my defense of Randy Kemp's "A Swedish Idea" suggestion, in which I suggested that Karl and Magnus were not just angelic geeks in computer heaven -- they have a profit motive. I see nothing wrong with that. Is there something wrong with me pointing that out? The discussion went off course when I suggested that my response to Saint Karl may have been blocked (i.e., censored). I will apologize immediately and publicly when any one of my three attempts to post that response goes through. I did not publicly discuss the license violation until my sanity and credibility was publicly challenged. So, you and Jeff touched a raw nerve with me. I'd really like for you both to lay off the mental stability cracks.

Try again, the mailing list software was down for a couple of days last week(See Jay, other people lost emails too!)

What does it take to unsubscribe from this group ? I have followed the instructions, but I am still getting email.

JMS question: How to connect to a remote host
Hi folks, I'm just tring out the JMSChat sample. I'm want to run it from another host as the orion server is running. But this seems not possible since I got the following error message "Communication error: Unable to connect to JMSServer (localhost/127.0.0.1:9127): Connection refused:" So is there a Property or method which I can use to connect to another host.

JMS question
Some of us noticed that when you are programming JMS w/ orion, the strange NULLPointerException goes away when you take the connectionfactory lines out of the jms.xml in 1.4.7. Can anyone explain why the NPE goes away when those connectionfactory lines are taken out of the jms.xml in 1.4.7 but not in 1.5.1. thank you very much __ Do You Yahoo!? Yahoo!

Re: JMS question, topics mixed up? Problem fixed.
Hello everyone again! The problem has been solved. I missed to fill in the declarations in config/jms.xml. However, the error was confusing, and a good guess is that the application should not be able be run in the first place without the declarations in jms.xml. I would still be interested in clarifications and experiences about these matters. Also the status of the Orion JMS server would be very interesting to know more about, mostly since we consider to use Orion as a production platform. /August - Original Message - From: August Linnman To: Orion-Interest Cc: Robin Rosenberg Sent: Tuesday, August 22, 2000 12:08 AM Subject: JMS question, topics mixed up? Hello everyone! I have a rather mysterious problem related to Topic Pub/Sub. My application defines two separate topics used for different purposes, but no matter what I try all TopicSubscribers will receive data posted on *both* topics. I am somewhat a newbie to JMS, but not to messaging systems, and this is not what I expect from the Orion JMS server. Am I running into a known problem? The mailing list contains so far very few postings on JMS. What is the status of the Orion JMS server? Thanks in advance for all advice. /August
