Error in looking up a session bean from simple client

Question

Hi,
I have the following problem: (*+{color:#008000}Urgent problem my project depends on this problem to solve please help{color}+*)
I completed the "Create a Simple EJB Session Bean" example from cue cards tutorials from jdeveloper 11 g final release, and run the "HelloWorldSession" and waiting for server to finish its initialization.
Note:
Session bean code:
import javax.ejb.*;
+@Stateless(name = "HelloWorldSession", mappedName = "SessionEJB-SessionEJB")+
+@Remote+
+public class HelloWorldSessionBean implements HelloWorldSession {+
+public HelloWorldSessionBean() {+
< <em>public String sayHello(String name) {+
return "Hello " name;+
+}+
HelloWorldSessionClient code:
+public class HelloWorldSessionClient {+
< <em>public static void main(String[] args) {+
+try {+
final Context context = getInitialContext();
HelloWorldSession helloWorldSession =
+(HelloWorldSession)context.lookup("*SessionEJB-SessionEJB#eg.com.efinance.HelloWorldSession*");+
System.out.println(helloWorldSession.sayHello("world"));
+} catch (Exception ex) {+
ex.printStackTrace();
< <em>+
< <em>private static Context getInitialContext() throws NamingException {+
Hashtable env = new Hashtable();
+// WebLogic Server 10.x connection details+
env.put(Context.INITIAL_CONTEXT_FACTORY,
+"weblogic.jndi.WLInitialContextFactory");+
env.put(Context.PROVIDER_URL, "t3://127.0.0.1:7101");
return new InitialContext(env);
+}+
Then on HelloWorldSessionClient right click then run I got the following errors:

Hello
The problem is beacause weblogic doesn't allow blank spaces in the CLASS PATH, so try that in your path doesn't exit blank spaces like these:
C:\Documents and Settings
