I have eclipse juno and jboss AS 7.1 final running on my machine and configured it through it (eclipse juno). I hava a simple stateless bean and its interface (in fact is exactly the same example from the book Enterprise Java Beans 3.1 6th Edition). Here is the code:

package beans;

public class CalculatorBeanBase implements CalculatorCommonBusiness{

    public int add(int[] opers){

        int sum = 0;
        for(int c:opers){
            sum+=c;
        }
        return sum;
    }

}

package beans;

public interface CalculatorCommonBusiness {

    public int add(int[] opers);

}

package beans;

public interface CalculatorRemoteBusiness extends CalculatorCommonBusiness {}

package beans;

import javax.ejb.LocalBean;
import javax.ejb.Stateless;

@Stateless
@LocalBean
public class SimpleCalculatorBean extends CalculatorBeanBase {}

I am trying to do the following JUnit testing, unfortunately the example mentions something like “using a standard jndi.properties file that we assume to be presente on the classpath” (here is my first problem, I have no idea what this means, I in fact did some research but I cant quite understand how it works, confuses me, and ultimately cant seem to make it work).

package beans;

import javax.naming.Context;
import javax.naming.InitialContext;
import junit.framework.TestCase;
import org.junit.BeforeClass;
import org.junit.Test;

public class CalculatorIntegrationTestCase {

    private static Context namingContext;
    private static SimpleCalculatorBean cal;
    private static final String JNDI_NAME_CALC = "java:global/jndi.properties/SimpleCalculatorBean";

    @BeforeClass
    public static void obtainProxyReferences() throws Throwable {
        namingContext = new InitialContext();
        cal = (SimpleCalculatorBean)namingContext.lookup(JNDI_NAME_CALC);
    }

    private void assertAdditionSucceeds(SimpleCalculatorBean cal){
        final int[] oper = {2,3,4};
        final int expectedSum = 9;
        final int actualSum = cal.add(oper);

        TestCase.assertEquals("Assert Failed!!. The actual value is not the expected",expectedSum, actualSum);
    }

    @Test
    public void testAdditionUsingBusinessReference() throws Throwable {
        this.assertAdditionSucceeds(cal);
    }
}

I need to know how that jndi. properties file works and how I have to set it up. (I read about this last issue, and I got the folloing .txt file and changed its extension to .jar, I dont know if that was right):

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

Finally I put that .jar file into the classpath (Don´t know if I did it right: rigth-click on project, build path, libraries, add external jars).

I did all the above stuff but I keep getting the following:

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

Of course I published the Project (through eclipse though, project>run>run on server). Help would be appreciated
