Re: Orion and JMS: javax.naming.NameNotFoundException]
Hi Kesav, Thank you very much for your help, it was as simple as that. Thanks again, Dan Kesav Kumar wrote: If you want to get any resource in your Servlet/jsp you got define resource-ref in your web.xml. One basic information as long as you are in the same container you don't need any parameters to JDNI context. You need jndi.properties only when you try to access from outside the container. Your servlets/jsp/ejb/applicationclient are in the same orion container so in all these components you can directly get JNDI context by Context ctx = new InitialContext(); As long as you are in the same container there is no need for jndi.properties. Regarding the JMS you got define resource-ref in your web.xml. Any container resource of ejb resource you want to use in web tier i.e in servlets/jsp you have to define resource-ref and ejb-ref correspondingly. For JMS which is a resource so you have to declare resource-ref in your web.xml like the following. resource-ref res-ref-namejms/theQueueConnectionFactory/res-ref-name res-typejavax.jms.QueueConnectionFactory/res-type res-authContainer/res-auth /resource-ref resource-ref res-ref-namejms/myQueue/res-ref-name res-typejavax.jms.Queue/res-type res-authContainer/res-auth /resource-ref Inside your servlet/jsp for connection factory lookup for jms/theQueueConnectionFactory and for queue lookup for jms/myQueue. snip...
Re: Orion and JMS: javax.naming.NameNotFoundException]
Hi David,
Thank you for your help, this example code might be very useful. What
I'm trying to do is centralised login service, to allow a central
authentication service to control acces to different web applications
that can even be in different hosts. I already succesfully implemented
the login part, but now I want to be able to logout from all the
applications at once, and I also want to be able to trace in one place
the user movements through the different applications. That's why I
thought about using JMS to implement the communication between the
different applications and the central authorization site. My concern is
now whether JMS, specifically Orion's implementation, is mature enough
as to have all my applications depending from it. Or are JMS
implementations in general as inmature and buggy as Michel J. Cannon
stated?
Thank you again,
D.

Virtual DirecTory -- Help
Hellu, I am trying to exculde my JSP files from the war file, such that the designer can easily change them without my help (withoud deployment, etc...). Anyone any idea/advice how to do that as I tried many things, but appearantly am not able to succeed ? What I tried (I am running on a linux box, RedHat 7.0, Orion 1.5.1, JDK 1.3) ? - First I changed the jsp entry in my web.xml, from a relative path to a absolute path, that doesn't work, as he always starts looking from within the web application: --- servlet servlet-nameMainWebShop/servlet-name display-nameMain page of web-shop/display-name description/description jsp-file/home/development/vwr/web-client/jsp/webwinkel/html/main.jsp/jsp- file /servlet -- - I did add a virtual directoy entry in orion-web.xml of the the default web application, as the application runs under the default web application: - virtual-directory real-path=/home/development/vwr/web-client/jsp virtual-path=/VWR/jsp / However this doesn't work as the j2ee application itself listens to the root url /VWR/. It also tried the following: - virtual-directory real-path=/home/development/vwr/web-client/jsp virtual-path=/VWR_jsp / Which works but then the jsp's don't run in the application environment, and as such you need to make a connection as if you were an external j2ee client, which isn't very logical ofcource. - I tried to put a symbolic link in the war file to the jsp's, but jar doesn't understand that. It will just copy all the files. Any ideas are more than welcome. Eddie :(

RE: Orion and JMS: javax.naming.NameNotFoundException]
Daniel,
For the logout service I think I would use durable 'logout' topic which
would guarantee delivery. If you believe you might run into high volume
degradation, then look at SonicMQ messaging server. They wrote the book on
JMS -- literally.

Yahoo Orion List
Hello, I fully support starting another Orion list to replace this one, but could the person who started it please send a message to this group on the details of signing up for it? I would also suggest crafting a message that can be sent to this group occasionally to explain the purpose of the new list, who its moderator is, etc. Also, we should notify Orion(Ironflare) and see if they can put a link to the new list on their site. It is very possible that they would have no problem with this, since they obviously took no real interest in this list anyway. If they do agree, it would probably take them 3 months to post it on their site, but its worth a try :) Bill

Dear Group, As many of you know, I am a frequent contributor to the list. About three months ago, we had a long thread on the need for customer support for Orion. In late June, I contacted Karl Avedal with Ironflare about my company providing support for Orion. Karl was very encouraging, so my company decided to go forward with this venture. Last Friday our support site went up, www.elephantwalker.com. In the site, we provide a free public application for users to post their questions about Orion. Users can up-load files to the forum as well as bury a topic when the problem is solved...a very useful feature when a problem is solved. We hope that Elephantwalker Support Site will be useful and more reliable than the email list. We also offer subscription-based customer support for the Orion(tm) Application Server. Users may purchase on-line or phone-based support packages. In addition, we offer a client-site, two-day Orion class in the San Francisco Bay area Join us at www.elephantwalker.com, its free! As far as reliability is concerned, the site is hosted at Upnetworks in San Francisco, a telecon grade facility. This means that even during a power failure or natural disaster the site will continue to operate. We use two separate servers for the site for reliability. The back-end is Oracle which is running on a raid configured server for reliability. This site won't go down. As far as band width is concerned, Upnetworks has several OC-64 network connections to the internet. Many have asked what technology we use to power the site. Here is a short list: 1. Redhat 7.1 with the enterprise kernel is used on the application servers. 2. Two Orion application servers are used to serve up the web pages and enterprise application. 3. The enterprise application is a distributable forum application so that if one server goes down, the other server will continue to serve up web pages. The users will never know that their server has gone done, since the session are shared across the cluster. This is unlike another well known forum application, Jive's, which is not distributable. 4. The forum application allows users to up-load files and have lengthy forum messages. We have imposed a limit of 50k per message, and 2 MB for up-loads, but our technology has no limit on the message size or file size. The application is run completely within Orion as an ear file. 5. Our back-end is Oracle 8.1.7, but we do not use any special Oracle features. For those of you on the list, don't despair, I will continue to contribute to the list. regards, the elephantwalker
Re: Yahoo Orion List
Hi - nevermind. by the time this came through list, my question had already been answered. Which i guess is one of the reasons we needed a new list :) Bill Bill Clinton wrote: Hello, I fully support starting another Orion list to replace this one, but could the person who started it please send a message to this group on the details of signing up for it?

RE: I think, I will start a support site too....
Group, In order to battle the big boys, Orion needs us all. This is why I started my support site. Although this is a commercial venture, our goal is to provide a support community for Orion. If you take a look at the submissions on the Oracle container support list, you can see that even Oracle needs some help in understanding some bits of Orion. For those of you who have already signed up at the site, thanks. I thought about just providing a maillist server, but felt that what we really needed was some type of forum application. Several of you have made suggestions about improving the site, and we are making these changes: 1. automatic logins. 2. wider input forms for the messages. 3. a message thread view as well as the default forum view. 4. next and previous message buttons. 5. message filters so that html tags in the message are not necessary. 6. search engine for the messages and the site. We are also adding a news application so that members can directly add news to the site. The up-coming tips and hints page will include the steps that were taken to build the forum application, including: 1. breaking the 4k barrier for clobs and lobs in Oracle. 2. distributing the application so that session clustering works. 3. encrypted user security. Regards, the elephantwalker
