[ravishastri]

I am getting the following error when I run Client.java
javax.naming.NoInitialContextException: Cannot instantiate class: org.jnp.interf
aces.NamingContextFactory [Root exception is java.lang.ClassNotFoundException: o
rg.jnp.interfaces.NamingContextFactory]

my client.java(bean deployed successfully)


import javax.naming.*;
import javax.rmi.PortableRemoteObject;
import java.util.Properties;
import com.javapro.ejb.StringProcessor;
import com.javapro.ejb.StringProcessorHome;

public class Client {

public static void main(String[] args) {

// first argument must be the input
if (args.length==0) {
System.out.println("Please specify the input to convert to upper case.");
return;
}
String input = args[0];
//Properties properties=System.getProperties();
// preparing properties for constructing an InitialContext object
Properties properties = new Properties();
properties.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
properties.put(Context.PROVIDER_URL, "165.197.127.98:8080");

try {
// Get an initial context
InitialContext jndiContext = new InitialContext(properties);
System.out.println("Got context");

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

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

// Create an Adder object from the Home interface
StringProcessor sp = home.create();
System.out.println ("Uppercase of '" + input + "' is " +
sp.toUpperCase(input));
}
catch(Exception e) {
System.out.println(e.toString());
}
}
}

make sure jnp-client.jar is in your classpath

[ravishastri]

java -classpath C:\JBoss-3.0.6\client\jboss-client.jar;C:\JBoss-3.0.6\client\jnp-client.jar;. Client "golden retriever"

make sure the jars from jboss/client dir are in your classpath

[ravishastri]

I have done that,but still error persists
set path=%PATH%;C:\jBoss-3.0.6\client\*.jar

[cbwilliams]

You've changed the PATH. You need to change the classpath...

set CLASSPATH=%JBOSS_HOME%\client\jnp-client.jar;%CLASSPATH%

this of course assumes that you've set the JBOSS_HOME environment variable.
