Hi, The Elephant walker.
Sure the error says domain was null, but the situation is that the
servlet is just an another stand-alone program (not part of deployed Hello
Session Bean) residing in
D:\Oracle\iSuites\j2ee\home\default-web-app\WEB-INF\classes\trg\HelloServlet
directory and from there I'm trying to access Hello Session Bean which is
deployed on the Orion. Both client and server are on the same machine as
I'm testing this saught of workability. So I guess domain name won't be
needed and if yes could you elaborate on domain name you are talking about
Regards
Prashant

First, if the servlet and ejb are in the same application, you don't need to
use properties to initialize your contextbut if you did, it looks like
you left off the domain in the properties.

Subject: Calling EJB From a Servlet..
HI Friends,
I'm having a serious problem in my code and am unable to
understand. I've deployed a simple Hello bean on the orion container and
want to access it from a servlet. I have the servlet in
D:\Oracle\iSuites\j2ee\home\default-web-app\WEB-INF\classes\trg\HelloServlet
. Following is the code in servlet
try {
trace(In Try);
Hashtable h = new Hashtable();
h.put(javax.naming.Context.INITIAL_CONTEXT_FACTORY,com.evermind.server.rmi.
RMIInitialContextFactory);
h.put(javax.naming.Context.SECURITY_PRINCIPAL,
ejb);
h.put(javax.naming.Context.SECURITY_CREDENTIALS,
ejbadmin);
h.put(javax.naming.Context.PROVIDER_URL,ormi://localhost/Hello);
trace(Before Init Contect );
Context context = new InitialContext (h);
trace(after Initial context);
Object boundObject =
context.lookup(java:comp/env/ejb/HelloHome);
trace(At Trap);
helloHome = (HelloHome)
javax.rmi.PortableRemoteObject.narrow(boundObject,HelloHome.class);
}
catch (Throwable exception) {
exception.printStackTrace();
//System.out.println(Look up exception : +
exception.toString());
//throw new ServletException(
// Unable to get home interface: + exception.toString());
}
When I run servlet from browser I get an exception when the Context is
getting crerated as folloew

webserver proxy plugin + i/o question
hi all, i am new to orionserver but i have read the docs and the archives relating trying to find information relating to: i) Webserver proxy plugins ii) The type of i/o handling used. A variety of appserver vendors (BEA/IBM) recommend an architecture of a high performance webserver ( iplanet/apache ) proxying on requests to the appserver. This has several benefits including limiting the exposure of the appserver to the outside world. I was hoping to eval orionserver in a similar environment. However the only mention of a webserver handling in orion is to use the tunnelling servlet which still seems to require the orionserver to be exposed to the outside world. Is this the case? What is the I/O mechanism used in orionserver's request handling? I assume that it is using java's blocking i/o, is this correct? any help appreciated. adios -lp [EMAIL PROTECTED] Titan Court 3 Bishops Square Business Park Hatfield AL10 9NE Hertfordshire England tel : +44 01707 289 798 fax : +44 01707 289 941 __ http://www.one2one.co.uk _ NOTICE AND DISCLAIMER: This email (including attachments) is confidential.

Hi, You can use Apache as a reverse proxy (see this article http://www.orionsupport.com/articles/apachefrontend.html on orionsupport) In the future AJP13 could be provided.

look to the site www.orionserversupport.com there are many useful articles and tips, including one on how to use Apache as a proxy to orionserver ie.e. apache serves the static html, while orion serves servlets/jsp and manages ejb invocations.. -Messaggio originale- Da: Lucio Piccoli [mailto:[EMAIL PROTECTED]] Inviato: mercoledì 12 settembre 2001 11.13 A: Orion-Interest Oggetto: webserver proxy plugin + i/o question hi all, i am new to orionserver but i have read the docs and the archives relating trying to find information relating to: i) Webserver proxy plugins ii) The type of i/o handling used.

RE: Calling EJB From a Servlet..
The servlet is running on orion so you don't need to elaborate on the context. This should get your ejb: Context context = new InitialContext(); // Get home interface CommandHome cHome = (CommandHome)context.lookup(Command); // Create a command object Command command = cHome.create(); Command for me is a stateless session bean. snippet from orion-ejb-jar.xml enterprise-beans session-deployment name=Command location=Command wrapper=CommandHome_StatelessSessionHomeWrapper1 max-tx-retries=3 cache-timeout=60 persistence-filename=Command / /enterprise-beans Good Luck!
Re: Debugging with Orion/Kawa Pro 5.0
We had a problem where if you install Enterprise the uninstalled. Then installed Kawa Pro you could not run orion from inside. This is it!! I tried it on a computer that Kawa had never been installed on and it worked. Kawa is now giving me a message that it can't find server.xml so I guess I have to tell Kawa to look in the orion\config directory or add server.xml to the project. Thanks alot Owen! -Dennis Owen Fellows wrote: I remember seeing something about orion not working in Kawa Enterprise. We had a problem where if you install Enterprise the uninstalled.

Can't remember if this was orion but there where issues with changing Kawa'a (if think kawa released a patch to fix it). -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of DENNIS STRAIGHT Sent: 07 September 2001 06:48 To: Orion-Interest Subject: Debugging with Orion/Kawa Pro 5.0 I appreciate Dave Smith's write-up on debugging with Orion/Kawa but, unfortunately, I think I'm missing something and need more info. Here is what I did: Created a new project with all of my java files (servlets, EJBs, and regular Java). Added Orion.jar to the Kawa classpath. Set the class to run to com.evermind.server.ApplicationServer Made sure JVMDI was turned off Added breakpoints, hit F5 and... nothing happens, I don't see orion starting in Kawa's output pane... I don't see anything. Next, I open a web browser set to a localhost url that works fine when I run Orion from DOS and, of course, the page is not found. Because Orion hasn't started, I'm sure. Does anybody know what I'm doing wrong (Why Kawa isn't starting Orion)? Below I'll print Dave Smith's debugging tips, if anybody can tell me anything that is missing I would greatly appreciate it. Thanks, Dennis Dave Smith adds: Debugging with Orion and Kawa is a pleasure. Get Kawa Pro (not the enterprise version) from Tek-Tools and install it. Configure your JDK as required when you first run Kawa. (Note that Kawa is a Win32 application, which is one of the reasons I don't use it.) Create a new project for your servlets or EJBs. Add orion.jar, any additional jars required by the application, and the deployed class directory (i.e., c:\applications\myApp\myApp-web\WEB-INF\classes or c:\applications\myApp\myApp-ejb, or both). From the Project/Interpreter menu, set the Java class to run to com.evermind.server.ApplicationServer and remember to tell it to use this class (as this image, given me by Chris Miller, shows). Turn off JVMDI debugger from the Customize/Options/Advanced Paths form, which is for performance only and is not vital. Add the breakpoints to your servlets and/or EJBs. F5 starts debugging, and Dave adds to Relax, sit back and enjoy the ride. The speed kills NetBeans dead. Also from Dave: For a real screamer, use Jikes: Customize/Options/Advanced Paths/Compiler = D:\jikes\jikes.exe +E And set Orion to use jikes from $ORION/server.xml.
Help!!Subject.getSubject(AccessControlContext) returns null
Hi: I've been trying to send the authenticated app client's Subject to a RMI Activatable server in another JVM. In the app client, I run the follwing: AccessControlContext ac = AccessController.getContext(); Subject sbj = Subject.getSubject(ac); However, sbj turns out to be null. Is it because ac is NOT the Subject that's authenticated at the beginning of the app client run? Thanks XW
