Naming Context problem

[A Kumar]

Hi all,

I am trying to develop a simple session bean and deploy in jbos..but am getting an error while running the client..I was able to deppoy the EJB on the server but the client is giving errors....Can u please tell me Where i have to correct??


The Client

package org.jboss.docs.interest;

import javax.naming.InitialContext;
import javax.rmi.PortableRemoteObject;

import org.jboss.docs.interest.Interest;
import org.jboss.docs.interest.InterestHome;

/** This simple application tests the 'Interest' Enterprise JavaBean which is
implemented in the package 'org.jboss.docs.interest'. For this to work, the
Bean must be deployed on an EJB server.
*/
class InterestClient
{
/** This method does all the work. It creates an instance of the Interest EJB on
the EJB server, and calls its `calculateCompoundInterest()' method, then prints
the result of the calculation.
*/
public static void main(String[] args)
{
// Enclosing the whole process in a single `try' block is not an ideal way
// to do exception handling, but I don't want to clutter the program up
// with catch blocks
System.out.println("Inside the program");
try
{

System.out.println("before the context");
// Get a naming context
InitialContext jndiContext = new InitialContext();
System.out.println("Got context");

// Get a reference to the Interest Bean
Object ref = jndiContext.lookup("interest/Interest");
System.out.println("Got reference");


// Get a reference from this to the Bean's Home interface
InterestHome home = (InterestHome)
PortableRemoteObject.narrow(ref, InterestHome.class);

// Create an Interest object from the Home interface
Interest interest = home.create();


// call the calculateCompoundInterest() method to do the calculation
System.out.println("Interest on 1000 units, at 10% per period, compounded over 2 periods is:");
System.out.println(interest.calculateCompoundInterest(1000, 0.10, 2));
}
catch(Exception e)
{
System.out.println(e.toString());
System.out.println(e.getCause());
}

}
}

The jndi.properties file has the following entries...

Add jboss/client/jbossall-client.jar to you client classpath.

Thanks buddy....It worked fine...i got the rezult..

Instead of using a .properties file i tried to supply them

in the source code and it worked..

i made the change in the above code of the client file..

/**********
//Add a hashtable

Hashtable props = new Hashtable();
props.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
props.put(Context.PROVIDER_URL, "jnp://localhost:1099");
//props.put(Context.URL_PKG_PREFIXES,"org.jboss.naming rg.jnp.interfaces");

System.out.println("Inside the program");
try
{

System.out.println("before the context");
// Get a naming context
InitialContext jndiContext =new InitialContext(props);

..........
...
..

Thanks
