RE: Help me please domain was nul message is killing me here...
Ray, the problem is quite simple. I have two Orion servers. One server is running an EJB application model, the other server is running JSP client application. From the JSP server, I try to access the EJB server, by creating an InitialContext with the same parameters that I would if I was trying to connect to the EJB application using a standalone client (appplication-client.xml and ApplicationClientInitialContextFactory). At this point, I get a NullPointerException on the Client (JSP Server) side telling me that the "domain was null". The exact same code, works correctly when running as a standalone application, however, when put into the JSP Server, produces this exception. Some people suggested using ApplictionInitialContextFactory, however, since ApplicationInitialContextFactory reads application.xml, I have no place to put my ejb-ref tags to reference the objects in the EJB application. Other people suggested playing around with rmi.xml. This, however, hardly seems standard. I am trying to write code that is J2EE compliant without having to use any of the Orion specific features. So I am at a standstill. It's hard to believe that no one ran into this problem. In many cases it does not make sense to deploy the client and server on the same physical machine. Our JSP clients are running on the public internet while our EJB models are running on the private internet not accessible from the outside. Also, since we have many clients, we anticipate having a "farm" of EJB servers running the model, and a "farm" of JSP servers accessing this model. I am amazed that no one has stumbled onto this problem. If you have two Orion servers running, put the following code on one of the servers: Properties p = new Properties(); p.setProperty(Context.PROVIDER_URL, "ormi://target-host/application-name"); p.setProperty(Context.INITIAL_CONTEXT_FACTORY, "com.evermind.server.ApplicationClientInitialContextFactory"); p.setProperty(Context.SECURITY_PRINCIPAL, "user"); p.setProperty(Context.SECURITY_CREDENTIALS, "password"); InitialContext ctx = new InitialContext(p); You will need to replace target-host, application-name, user and password with values for your system. You will need to put the application-client.xml in to the proper directory. For a web application, this file should go into WEB-INF/classes/META-INF/application-client.xml. -AP_ -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Ray Harrison Sent: Monday, April 02, 2001 8:16 PM To: Orion-Interest Subject: Re: Help me please "domain was nul" message is killing me here...

Re: Help me please domain was nul message is killing me here...
i am also trying to get two orion servers talking to each other, on server A i have declared an ejb-module to be remote (orion-application.xml), this module runs on server B. Server B is declared in the rmi.xml file as another rmi server for server A, I lookup the ejb from the remote module, and then get a Class Cast exception when trying to narrow the object, to the home interface. any advice on how to get this working would be much appreciated, colin.. - Original Message - From: "Alex Paransky" [EMAIL PROTECTED] To: "Orion-Interest" [EMAIL PROTECTED] Sent: Tuesday, April 03, 2001 7:28 AM Subject: RE: Help me please "domain was nul" message is killing me here...

Re: Help me please domain was nul message is killing me here...
I've gone back through your emails and don't have an overall picture of your application. Perhaps I am more dense than the average bear, but go ahead and give an overall picture of your application - like: This app is distributed over N orion server[s] and the configuration is done in the following manner... and I am trying to accomplish the followingand then I get this "domain was null" error, etc. That way myself and perhaps others can help out and it won't take 4 weeks to do so. Just a question out of curiosity: Have you looked at other app servers and do they support what you want to do in the way you want to do it - like JBoss,WebLogic,EAServer? Cheers!

Re: Help me please domain was nul message is killing me here...
PS: Is this what it takes to get a question answered? Is there a different forum for paying customers? If I pay $1500, will I get my questions answered faster? One would assume so. Paying customers are prioritised in the support queue (from personal experience). Hani Interesting. As another paying customer, this hasn't been my experience. I'm ignored just as completely as non-paying customers. This ignoring includes formal messages to Orion's support email address as well. We're still in development, but purchased a license in the hope that something resembling support would be forthcoming. It was a misguided expenditure in that regard. P.

RE: Help me please domain was nul message is killing me here...
I have had the same problem Alexto further muddy the matter I still
haven't figured it out. I have opted to sipmply circumvent this option
and do my own method of remote invocation (EJB in one server invoking an
EJB in a another server). What I do remember reading , is that you need
to set the "parent attribute" in the application definition in server
.xml. If you look at the docs it specifies that this kind of scenario
can be accomplished by doing just this..
i.e. the invoker is a child of the invoked.
The problem I had, with this , is that I could never get it to work; I
could never figure out the syntax.- parent ="ParentApp". - This only
works if the other application is on the same physical server. The
moment you try to append a server name to this application name i.e.
parent = "remote-host/ParentApp" or even parent =
"ormi://remote-host/ParentApp" this goes to hell !!! If this is supposed
to work, that implies that the syntax tried out was wrong
Anyway this might not be of any help, but you may want to try
investigating the parent deal further (in server.xml when you define the
application). It might lead to some undiscovered truth
If you do find out, could you please let me know as well !! I developed
a kludge to bypass this scenariowhich I would like to rep-lace with
a functional soloution
Good Luck !

If you have two Orion servers running, put the following code on
one of the

Properties p = new Properties();
p.setProperty(Context.PROVIDER_URL,
"ormi://target-host/application-name");
p.setProperty(Context.INITIAL_CONTEXT_FACTORY,

p.setProperty(Context.SECURITY_PRINCIPAL, "user");
p.setProperty(Context.SECURITY_CREDENTIALS, "password");
InitialContext ctx = new InitialContext(p);
You will need to replace target-host, application-name,
user and
password with values for your system. You will need to put
the
application-client.xml in to the proper directory. For a web
application,
this file should go into
WEB-INF/classes/META-INF/application-client.xml.
