Question about: javax.naming.NameNotFoundException: FooBean/remote

[Thomas Chang]

I create an ejb3 running on Jboss according to (http://javahowto.blogspot.com/2007/11/simple-ejb-3-on-jboss-application.html)

First I start the Jboss AS locally on my PC and I run the Client also successful.

Later I deployed the ejb-jar to a remote Jboss AS on a LINUX machine. And I can find the jndi in the JNDIView of jmx-console as follow.

  
...
  +- FooBean (class: org.jnp.interfaces.NamingContext)
  |   +- remote (proxy: $Proxy121 implements interface foo.FooRemote,interface org.jboss.ejb3.JBossProxy,interface javax.ejb.EJBObject)
...
 

This means the deployment is successful.

Though I've changed the IP in the jndi.properties, I got exception as I start the Client.

...
D:\Temp\MyProjects\TestEjb\classes>java -cp %JBOSS_HOME%\lib\*;%JBOSS_HOME%\client\*;%JBOSS_HOME%\server\default\lib\*;.
 foo.Client

What could be the problem?

The jndi.properties looks as follow:

java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
java.naming.provider.url=172.23.17.40:1099

What version of JBoss AS are you using? That tutorial is a really old one and things have changed greatly since 5.0.0.Beta2! Here is the latest tutorial: http://docs.jboss.org/ejb3/docs/tutorial/1.0.7/html/index.html

Many thanks.

I solved the problem. It was the problem of firewall, i.e. the firewall block the communication between the two machines.


But I am still looking for example for testing the clustering of Web Application. The example in your book is about testing or playing clustering with EJB.
