after create the bean the server was halt
Hi All, I am moving my weblogic6.1 EJBs to my orion 1.5.2 server. Ican deploy thoseEJB in Orion1.5.2 server on NT platform.I use a test program to invoke that bean. It works fine at the first time. However, I lookup again. The orion was halt ever I use the control C. The server seemsholding some service or background jobs. Is that because of Weblogic6.1 using ejb2.0 and orion using ejb1.0?

Re: Urgent :: How to access JMS service from Servlet/JSP
You don't need application-client.xml if you want to access JMS from servlets. You have to write your queueconnection and queues in web.xml. Add resoure-ref entries in web.xml 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/processQueue/res-ref-name res-typejavax.jms.Queue/res-type res-authContainer/res-auth /resource-ref Once you have the resource-ref entries in web.xml from your servlet write the following Context ctx = new InitialContext(); QueueConnection con = (QueueConnection)ctx.lookup(java:comp/env/jms/theQueueConnectionFactory); Queue queue = (Queue)ctx.lookup(java:comp/env/jms/processQueue); I didn't understand your question of different containers? Do you mean different containers different orion server? If you want to get access JMS queue/connection of different orion server provide proper JNDI properties for obtaining InitialContext. Example: Hashtable env = new Hashtable(); env.put(Context.INITIAL_CONTEXT_FACTORY, com.evermind.server.ApplicationClientInitialContextFactory); env.put(Context.PROVIDER_URL, ormi://host/applicationname); env.put(Context.SECURITY_PRINCIPAL, username); env.put(Context.SECURITY_CREDENTIALS, password); Context ctx = new InitialContext(env); Rest of the code is common.

RE: How can I start Orion Server as a service in Windows NT/2000 ?
Hi Vu, You need the JNT application from http://www.eworksmart.com/JNT/ Install this and type a command similar to the following, from where you installed Orion: jnt "/InstallAsService:Orion Application Server" "/SD[ORION_HOME]" -jar orion.jar where [ORION_HOME] is where you installed Orion. Worked for me, anyway. I had a job getting other java apps to run using this tool though :( This has come up in the list before, so do a search on the archive for more info. One thing I have noticed is that Orion runs slower this way than if you start it from a command prompt. Anyone know anything about this? I've asked this before.

Login from client and retrieving info thru Ldap
I have worked for some time on the subj. To make it very clear I will start telling in a few words about the system. On the client side we are going to use Swing, connecting to a Orion server. We will just use simple authentication based on the System.getProperty(user.name); The server should then look up the user in Active Directory, and get the groups he is a member of. Based on these groups and the roles in ejb-jar.xml the server should administer access to the application. That's very short the application. Now my problem is implementing all this. I can not find any documentation telling me how to do it. Matthew Porter has been so kind to send me an implementation he has made called LdapUserManager. Based on this Manager I have the following questions: Firstly I would like to know how the client identifies to the UserMAnager/Orion who he is. It needs just to give the user.name of the user. Secondly, how do I tell the UserManager which attributes to take from the Active Directory in order to find out which groups he is a member of? How do I inform Orion on using LdapUserManager, and other classes from the com.linjafoo package? Reaching this point I believe that the server should do the rest by itself. The rest I reffer to adminestring the roles and access to the application. Please, correct me if I'm wrong. Now what I _think_ Orion will do, is that it will manage the access to methods and beans using the LdapUserManager. In my program code I will then also be able to ask isCallerInRole(role). One last thing is: Does there exits an independent implementation instead of using something based on the Orion model. I mean, is roles and grouips not part of the J2EE? I would prefer a independent way - write once run anywhere. That was many questions but I hope someone out their has been thru all this, and just knows how to do it :-) Thanks for any kind of help or comments.

Re: Monitoring web apps
Hi David, We don't have a sophisticated system, but it works well for us. What we do is put an Apache web server, acting as a proxy, in front of the orion server. Then, in the proxy configuration you can specify a redirect page in case something goes wrong, and we use it to redirect to a SSI script that determines which application is down and which page should be shown as an error message. This way you show automatically an error message, just by shutting down orion or by returning a 500 code from your application. I hope it helps, D. David Pérez Villanueva wrote: Hi! We have several applications running in an Orion web server. Our server is allocated in a hosting corporation.

Re: Monitoring web apps
Hi Eddie, Here it goes: .- Environment - An apache web server configured with mod_proxy and SSI, running in port 80. Several orion instances with applications running in other ports. .- in httpd.conf - ... VirtualHost _default_:80 ProxyVia On # Proxy configuration for the different applications # Application X ProxyPass /nameX http://hostx.com:portX/nameX ProxyPassReverse /nameX http://hostx.com:portX/nameX # Application Y ProxyPass /nameY http://hostx.com:portY/nameY ProxyPassReverse /nameY http://hostx.com:portY/nameY # Error configuration for the Cannot establish connection case ErrorDocument 502 /SSIErrorHandler.shtml /VirtualHost ... .- Then the SSIErrorHandler.shtml looks like - !-- Define application paths -- !-- Define the path for application X -- !--#set var=appX value=/^\/nameX/ -- !-- Define the path for application Y -- !--#set var=appY value=/^\/nameY/ -- ... !-- Check which was the redirected path and include the appropriate error page -- !-- If the original url was from application X -- !--#if expr=$REDIRECT_URL=$appX -- !-- Include the app X is not running, sorry error page -- !--#include file=localApacheDirX/index.html -- !-- If the original url was from application Y -- !--#elif expr=$REDIRECT_URL=$appY -- !-- Include the app Y is not running, sorry error page -- !--#include file=localApacheDirY/index.html -- !-- Error in an application with no specific message defined -- !--#else -- !-- Include the this app is not running, sorry error page -- !--#include file=localApacheDirCommon/index.html -- !--#endif -- And that's pretty much all. Just some catches: .- In the Error pages, ALL the links have to be absolute and start with a different name than the proxied path. Otherwise you get an infinite loop between the proxied page and the error page. So make sure that nameX and localApacheDirX are ALWAYS different and that all links in localApacheDirX/index.html start with /localApacheDirX or http://. .- If inside the applications you want to get the real remote IP instead of the proxy one, then you can use, for example, the mod_proxy patch written by Bjoern Hansen which includes the original IP in an http header (X-Forwarded-For). We used it because we needed to implement IP based security restrictions, which are not defined in the JSDK spec. We also used this IP based security restrictions to prevent acces to the applications by-passing the proxy, which is very important with SSL protected applications. .- It also works with ssl. .- To improve performance, you can also use the apache proxy as proxy-cache, to get the static content faster, but then be careful not to allow it to cache the dynamic pages you don't want to be cached. And make sure you have enough disk space ;). .- We haven't specified and ErrorDocument directive for the code 500 (internal server error) because we wanted to be able to see this kind of messages, but you can put it later on to show more graceful messages. .- We use SSI to define the error hanlding page, but you could use a JSP if you wished. We just did it to have a light weight proxy with no special add ons. I hope it helps, D. Eddie wrote: Daniel, The way you do this with Apache sounds very nice.
