i am new to ejbs. read the tutorial “http://www.myeclipseide.com/documentation/quickstarts/ejb3/” for having a start on ejbs 3.0. i am using Application server “jboss-4.2.2.GA” and myeclipse ide “MyEclipse_5.5.1GA”.
i have created the session bean and deployed it successfully. but now when i run the client, i get the following exception

javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial
at javax.naming.spi.NamingManager.getInitialContext(Unknown Source)
at javax.naming.InitialContext.getDefaultInitCtx(Unknown Source)
at javax.naming.InitialContext.getURLOrDefaultInitCtx(Unknown Source)
at javax.naming.InitialContext.lookup(Unknown Source)
at com.myeclipseide.ejb3.MyBeanClient.main(MyBeanClient.java:16)

can anyone tell the reason for this exception and what to do in order to slve this problem. if the answer can be please in detail. thanks

Can you paste the entire error here for me. Could you cross post this query on the ejb forums as well.

Can you go to MyEclipse > Installation Summary > Installation Details and paste the information here for me.

This is the error you get from JBoss when you omit the jndi.properties file (right under src). This file should contain the following entries:

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

Cheers,
Jean-Michel

well, after adding the jndi.properties file under the src, now i get the following exception

javax.naming.NoInitialContextException: Cannot instantiate class: org.jnp.interfaces.NamingContextFactory [Root exception is java.lang.ClassNotFoundException: org.jnp.interfaces.NamingContextFactory ]
