hi.

check your ejb -jar and client jar. is there an old jar in the classpath ?
you can get an error if server and client uses different class files.

I've the same problem but i've fixed it.
i'm working with JBOSS 4.0.
personaly in my pc IIS services was running, and that was the problem, so i've stopped it : start -> configuration pannel -> administration tools -> services -> stop IIS
after that it works!! when I started the client

my client code :

public static void main(String[] args) {
String str = "This is the string being counted in the EJB.";
Hashtable environment = new Hashtable();

environment.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");

environment.put(Context.URL_PKG_PREFIXES,"org.jboss.naming:org.jnp.interfaces");

environment.put(Context.PROVIDER_URL, "jnp://127.0.0.1:1099");

Ccount cc = null;
 try {
 CcountHome home = CcountUtil.getHome(environment);
 cc = home.create();
 System.out.println(str);
 System.out.println(" Upper case: " + cc.upper(str));
 System.out.println(" Lower case: " + cc.lower(str));
 System.out.println(" Spaces: " + cc.spaces(str));
 System.out.println(" Total: " + cc.characters(str));

 } catch (Exception e) {

 e.printStackTrace();

 }
