Re: URGENT: talking with other app server?
Hi James.
I think , you can implement it.
Your servlet will just act as a client for other Application server.
For weblogic, you can download the evaluation version of Weblogic which is
free.
After deploying the bean to Weblogic you can include following lines
in the servlet.
Properties p = new Properties();
p.put(javax.naming.Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialC
ontextFactory");
p.put(javax.naming.Context.PROVIDER_URL,"t3://host-IP:7001");
p.put(Context.SECURITY_PRINCIPAL,"username");
p.put(Context.SECURITY_CREDENTIALS,"password");
Context cx = new InitialContext(p);
Object objHome = cx.lookup("jndi-name"); [jndi-name which is
specified in weblogic-ejb-jar.xml]
.etc.
While running Orion you have to also provide the classpath for Weblogic to
get Initial Context factory
which can be
weblogic-root\classes .

Subject: URGENT: talking with other app server?
Hi everyone.
Is it possible for a servlet deployed in orion talk to other app server
to access its beans? if so, how? what is the requirement?
I have got Orion using JNDI to use another Orion's bean, my main concern
is the fact that when initiating the JNDI context, I would have to
setthe property:
Properties props = new Properties();
props.put("java.naming.factory.initial",
"com.evermind.server.rmi.RMIInitialContextFactory");
props.put("java.naming.provider.url", provider.getPath());
props.put("java.naming.security.principal",
provider.getRemoteLogin());
props.put("java.naming.security.credentials",
provider.getRemotePasswd());
props.put("dedicated.connection","true");
props.put("classLoader",StampHome.class.getClassLoader());
context = new InitialContext(props);
What if talking with weblogic? I would have to change the
ContextFactory..can I download any impl from weblogic and use it (for
free) ?
If you can help, please reply Asap, thanks a million!
James.
Re: EJB-lookup problems with moved Product ejb example
Hi Vivek. I think, the error you got in the fifth step is because you have changed from ejbsamples domain to pricing. So you have to specify it in the URL. You can use following lines while running the client. Properties p = new Properties(); p.put(Context.INITIAL_CONTEXT_FACTORY,"com.evermind.server.ApplicationClient InitialContextFactory"); p.put(Context.PROVIDER_URL,"ormi://IPAddress/pricing"); p.put(Context.SECURITY_PRINCIPAL,"username"); p.put(Context.SECURITY_CREDENTIALS,"password"); Context context = new InitialContext(p); .....context.lookup(..) etc. Shailesh Joshi Java Programmer Versaware (India) Ltd. - Original Message - From: Vivek Iyer [EMAIL PROTECTED] To: Orion-Interest [EMAIL PROTECTED] Sent: Tuesday, October 17, 2000 8:40 AM Subject: EJB-lookup problems with moved "Product" ejb example Hello all, I'm getting a frustrating problem trying to bring up the "Product" entity bean inside Orion 1.4.0 (after latest autoupdate - though I had the problem with 1.3.4 as well). It only happens _after_ I move the location of the class files from d:\orion\demo\ejb\product to d:\vivek\pricing\ejb\product.

I can't believe this is just happening because I change the location of the class files and meta-inf files. I noticed someone else got this error some time ago, but no solution was posted.

INITIALIZED ORION, deployed the ejbsamples, and the "ProductClient" successfully ran, out-of-the-box. All classes are located in d:\orion\demo\ejb\product\ 2. COPIED the jndi.properties, ProductEJB, ProductHome and Product (remote interface) and ProductClient to d:\vivek\pricing\ejb\product\ and all the meta-inf files (application-client.xml, ejb-jar.xml, orion-application-client.xml) _without change_, recompiled all the files. Added an application.xml file into d:\vivek\pricing\ejb\meta-inf\application.xml with the following lines - application display-namePricing/display-name module ejbproduct/ejb /module /application 3. COMMENTED out the "ejbsamples" part of orion's server.xml. Deleted that application's deployment files. Added the following application to server.xml: application name="pricing" path="d:\\vivek\\pricing\\ejb" / 4. RESTARTED Orion. Observed that Auto-deploying pricing (New server version detected)... Auto-deploying product (No previous deployment found)... done. Orion/1.4.0 initialized 5.

Re: Stopping the Server
Hi Miles , Youmight be using the port no in the url while stopping the server. (e.g. ormi://localhost:80) If you are using it omit it. The same exception I got while getting Initial Context, if port no. is specified. It works fine without giving the port no.

Classpath : Orion On Linux
Hi All
I have installed Orion 1.3.8 on Linux server.
I have deployed beans and running clients successfully.
The problem is the server can't get the Driver in Class.forName("
");
I have copied driver class in the orion-root directory; set the
classpath .
But still the server is not able to get the class ?
FROM WHERE ORION TAKES THE CLASSPATH ?
With regards
Shailesh
