Reading Properties File
Hello Everybody, I have to read a properties file inside my EJB's method(I know the about EJB specs. restriction). As far as I know, to read a properties file in Orion we can specify the name of properties file with -p switch at orion server starting, or copy the properties file in ORION_HOME\lib directory(this directory is included in classpath setting through the manifest file). This solution works for me only if i read the properties file using getResource method of java.lang.Classloader for getting the URL of the resource, but if i use getSystemResource it fails. 1) So what's the difference in between getResource and getSystemResource method of java.lang.Classloader?? I read the java docs for these methods but it is still not very clear to me. Secondly, But In our application we don't want anything like above solution, we wish to include the Properties file in system classpath, and then our EJB should be able to read the properties file. 2) Is this is the right way ?? I tried but it was unsuccessful. May be i am missing something. I couldn't figure out why getSystemResource method is failing in this scenario, where system Classpath contains the conf file. any clue?? Thanks Naresh
Invoke a method on myself in a Stateful Session Bean.

Is there any other way to do this? I don't want to invoke the methods

Stateful session bean creating two entity beans
App-server: Orion 1.51, Windows 2000 Databas: Sybase 11.9.2 on Solaris JDBC: JConnect 5.2 Hi! We have a problem with an stateful session bean creating two entity beans. About one time out of four, only one of them is created and we get a rollback. We cannot find a pattern. And the exception we get is really hard to decipher. We have tested the application on other machines, and cannot reproduce the bug. We have Orion and Sybase running in the developing environment too. The big things that happen in the code is this: We try to create a entity bean called WizardData. This always succeedes. Then we try to create another entity bean, and that fails sometimes. The message from the exception is this: Exception.toString()- java.lang.ClassCastException: [Ljava.lang.String; Exception.getMessage()- [Ljava.lang.String; [Ljava.lang.String seems to be an array of Strings. Why does the exception return an array? How can we get more information about this exception from Orion? /Markus

I happened to be deleting the 7000 emails I have in archive of the Orion-list and decided to search for clustering. I cam across your thread, and I am having EXACTLY the same problem you are. The only difference is, I have the load-on-startup in my web-site tag, and I am still seeing the same results. One server shows the Sending... the other one shows nothing. Not sure if it is supposed to or not. I would list my config, but its at home. I am hoping you can help me figure this out as I am writing a chapter on scalability using a simple cart based web-app, and I want to test it for session fail-over, and explain how it works in this chapter. In my email to the list I am trying to find out how in general servlet containers fail over. When you use the setAttribute() call, does it copy the entire session of that user to the other server(s) in the cluster? Or does it just copy the one object and the other server(s) are smart enough to insert it into the right session? OR..worse..does it copy ALL sessions of all users to the other servers??!! If so, what happens when you have a session of 500MB of objects..does it take like 2 minutes to replicate the session, bring Orion to a crawl, etc? Thanks for your help and info.

RE: SMP/Linux/Hotspot/Orion problem.
I currently have several SMP machines running Redhat 6.2 or 7.0, running Orion 1.5.2, and using Suns JDK 1.3.0_02 or 1.3.1. We did see some problems on hotspot when we were using 1.3.0 that caused long unexplainable pauses (although ours were about 30 to 60 seconds). We spent a long time watching things like memory footprint (thinking it was maybe garbage collection) and CPU load, but nothing seemed related. With a lot of beating our head into a wall and a week of high pressure, we found that using the interpretted switch (-Xint) fixed these problems but still retained a reasonable performance. It appeared that just-in-time compiling was causing big problems on SMP machines, but more interesting was that moving to a newer JDK (e.g. 1.3.0_02 or 1.3.1) appears to fix the problem without any options to the JVM. -Original Message- From: James Hill [mailto:[EMAIL PROTECTED]] Sent: Tuesday, August 21, 2001 1:35 PM To: Orion-Interest Subject: SMP/Linux/Hotspot/Orion problem.

If foo() is under a transaction then calling bar() from foo() puts bar()
under the same tranaction.
The question becomes does bar() really need to be public? Is bar() called by
the Foo client directly?

EJB1.1 - dependent objects are not deleted...
I have an ejb called PersonEJB that is an 1.1 EJB. PersonEJB has PersonOrdersDO dependent objects. The dependent objects are mapped to a second table in the database. When I deploy the bean in Orion1.3.8, if I change the dependent objects, the container will update the records in the database, which is what I want. I just upgraded to Orion1.5.2 and deployed the same bean. There is one difference: when the dependent objects get changed the container will insert new records in the second table, rather than updating the existent ones. This is wrong, because it should just update the records, not produce new ones.This worked in 1.3.8, so is it a bug, and if it is in which server? Any help is appreciated. Thank you. ** This e-mail message is intended solely for the use of the addressee. The message may contain information that is privileged and confidential.

This solution works for me only if i read the properties file using getResource method of java.lang.Classloader for getting the URL of the resource, but if i use getSystemResource it fails. 1) So what's the difference in between getResource and getSystemResource method of java.lang.Classloader?? I read the java docs for these methods but it is still not very clear to me. Secondly, But In our application we don't want anything like above solution, we wish to include the Properties file in system classpath, and then our EJB should be able to read the properties file. 2) Is this is the right way ??

I couldn't figure out why getSystemResource method is failing in this scenario, where system Classpath contains the conf file. any clue?? Thanks Naresh

Trouble with Tomcat Client connecting to Orion Server EJB Bean
I have a java bean in a JSP page on a Tomcat Server that is
trying to talk to a EJB on an Orion Server.
The connection hangs trying to establish initialContext with the
remote server. No error message appears, and the connection never times
out.
Note: The Orion Server also has a client that talks to the EJB
locally and this works.
If I sit on the console of the Tomcat server, and "telnet
OrionServer 23971" then type some crap, I get:
"illegal ORMI request or request performed" proving the Orion
Server is listening on the port.
Client Code:
// Our Main Query
public String getResults(String UserName) {
try {
System.out.println("Start GetResults");
SecurityHome secHome = lookupSecurityHome();
Security secObject = secHome.create();
System.out.println("After Create secObject");
} catch (javax.naming.NamingException ne) {
System.out.println("lookupHome, NamingException:

}

I think, I will start a support site too....
(in style of Andy Rooney) I see everyone is starting their support sites for Orion. I think it's a poor solution for something that's broken, mainly, this mailing list. How many support sites do we actually have now? Why is it such a problem to keep the mailing list up and running? Now, we need to post the message to at least 3 places to make sure it gets maximum exposure. I think I will start a support site, that posts to all other support sites, just so that people don't have to search various support sites for help. I don't mind so many support sites starting up, I just think they are starting up for poor reasons and fragmenting what little knowledge we already have about this product. What is the problem with the list? Why is it down half the time? I hope it's not running under Orion... -AP_
Orion Clustering problems..
HI all, Hopefully this will make the list. I am working on a chapter for a book about scalability. I am also needing to get our site ready for scaling. I am using Orion to test my web-app that needs to be a demonstration of a scalable Servlet 2.2 web application. I have a couple of questions to ask about session fail-over, and how to get Orion to do this. I followed the cluster doc to the tee, and everything works fine except that the SessionServlet example does NOT keep the count going when I shut down the server that the first request to it created a session on. It starts over on the count. So I assume either my config is somehow just not correct, or that this is a bug with Orion. Here is what I have in my web-site.xml file: ?xml version=1.0? !DOCTYPE web-site PUBLIC Orion Web Site http://www.orionserver.com/dtds/web-site.dtd web-site host=192.168.0.10 port=8080 display-name=My Cluster Site cluster-island=1 frontend host=192.168.0.20 port=80/ default-web-app application=MyApp name=www/ access-log path=./logs/access.log/ /web-site I have the identical web-app and orion config setup for two machines. The second machine uses a different host ip address, but does use port 8080. Same island, and the frontend is set to the same IP as the one above. I also set the cluster-config/ tag in the /config/global-web-app.xml file of Orion, so that all web-apps deployed will be clustered. Finally, each web-app web.xml has the distirbutable/ tag in it. I run the loadbalance.jar file with the -debug option, and run each orion server with the two HTTP debug options. Everything runs fine. The loadbalancer starts up, I start the two servers, I see them both being added. I then make a request to the /servlet/SessionServlet. Comes up fine. The loadbalancer window shows the session id and what server it goes to. That server's orion window shows the session being created, etc. I open a new window and do the same thing, and this time the loadbalancer routes it to the other server and all is fine. Continuing requests from both browsers continue to send the requests to the same server their original request/session was created on. Now, if I shut one of the two down, the browser that has requests going to that server sometimes shows the 404 error as if the loadbalancer is not able to redirect its requests to the other server still running. Other times, it works, but the session counter starts over again. Also, I DO see from both orion server windows when I hit the SessionServlet and refresh it that it says sending.. or something like that, which I assumes means its sending the session data. However, on the other orion window I don't see receiving.. if that is even supposed to show up. Also, this doesn't do it every time I refresh the window..just some of the times. This I attribute to possible browser caching of the page..not sure though. So I am stumped as to why the sessions are not replicating properly, or at all. If someone can help out on this, that would be great. But this leads me into a few technical questions about session fail-over in general. First, I read one article, and someone here (or in the jsp-interest list) had explained how to replicate a session you must always use the setAttribute() or putValue() calls. The reason makes sense. If you run this code: MyBean myBean = (MyBean) session.getAttribute(MyBean); myBean.setName(SomeName); RequestDispatcher rd = request.getRequestDispatcher(/somepage.jsp).forward(request,response); then in the JSP page have: jsp:useBean id=MyBean scope=session class=mypackage.MyBean/ %= MyBean.getName() % You'll see that it works correctly..spits out the SomeName. However, the problem with this..at least from what I have read about writing scalable web-apps, is that the container has not replicated this change to another server (or servers) in the same cluster. The reason is, there is no way for the container to know a change to a field of an object in the HtppSession has changed. So this leads me to believe one of two things. Session fail-over only works if you call the setAttribute() call, which the container can implement to properly replicate the session to another server (in whatever manner is needed but I think multi-cast is the most common), or that the container MUST constantly replicate the session at some interval in order to make sure the other servers sessions are all kept in sync with this one (and vice versa for those servers sessions). So this raises a few problems and/or questions. First, if the container constantly replicates the session at some interval, how badly does that degrade the performance of the server (and the cluster as replicating involves serializing, sending, then deserializing and storing the deseralized objects (or object) into that servers session)? Also, how exactly is this done..I mean, is the entire Hashtable of ALL user sessions serialized, sent, and deserialized by the other servers, and at that point each of
Re: I think, I will start a support site too....
I personally think third-party support sites are a good thing. All of them I have seen so far are primarily commercial in nature, in order to counter the complaints of the corporate users that there was no 'credible support.' It's capitalism in action: see a need in the market and meet it. ...as to what the maillist runs, it really doesn't matter. All websites go down...Hotmail, Yahoo, even Slashdot...the rumor - never confirmed - was that it did indeed run on Orionserver. So what? Now you have another place to go when it is down (the new support sites). ...and if Orion is good enough for you to run a web site - (and it is: http:/www.standardset.com/ ) well, it should be good enough for Orion, especially since they developed it and this is one of the 'load and valence test platforms (if it does indeed run on Orion) for the product. Finally, the more info the merrier, and, given the levels of interest and participation by the people who have started these support sites and the support they have shown everyone on this maillist, I don't think any of us are going to suffer.
