can't get a client class to run
hi all,
this is my first post and i'm a j2ee newbie.
I'm studying a book 'headfirst ejb' at the moment. i've installed the server and configurated everything. the first example in the book creates a simple application where there's a string[] full of strings which are advice eg "don't eat yellow snow" :) i've three files AdviceBean, AdviceHome and advice. i can post the code if necessary. i've used the deploytool and compiled and deployed them to the server, everythings fine so far. i then have to run a client use the bean. the client class compiles but when i try to run the client it gives me a 'java.lang.noclassdeffounderror : AdviceClient '
this is what i typed to run the client
java -cp {$CLASSPATH}:AdviceAppClient.jar;C:\j2sdkee1.3.1\lib\j2ee.jar;C:\projects\advice\classes AdviceClient
has anyone got this book or can help?
thanks in advance
mat

sorry to double post but here are the.java files, the 1st 3 are on the server and the forth one is the one that is giving me the error.
Advice.java
package headfirst;
import javax.ejb.*;
import java.rmi.RemoteException;
public interface Advice extends EJBObject{
public String getAdvice() throws RemoteException;
}
AdviceBean.java
package headfirst;
import javax.ejb.*;
public class AdviceBean implements SessionBean {
private String[] adviceStrings = {"bbbbbbbb", "vvvvvvv", "gggggggggg"
, "jjjjjjj", "rrrrrrr", "qqqqqqqq"};
public void ejbActivate(){
System.out.println("ejb activate");
}
public void ejbPassivate(){
System.out.println("ejb passivate");
}
public void ejbRemove(){
System.out.println("ejb remove");
}
public void setSessionContext(SessionContext ctx){
System.out.println("SessionContext");
}
public String getAdvice(){
System.out.println("in getadvice");
int random = (int) (Math.random() * adviceStrings.length);
return adviceStrings[random];
}
public void ejbCreate(){
System.out.println("in ejbCreate");
}
AdviceHome.java
package headfirst;
import javax.ejb.*;
import java.rmi.RemoteException;
public interface AdviceHome extends EJBHome{
public Advice create() throws CreateException, RemoteException;
}
AdviceClient.java
import javax.naming.*;
import java.rmi.*;
import javax.rmi.*;
import headfirst.*;
import javax.ejb.*;
public class AdviceClient {
public static void main (String[] args){
new AdviceClient().go();
} // end of main
public void go() {
try{
Context ic = new InitialContext();
Object o = ic.lookup("Advisor");
AdviceHome home = (AdviceHome) PortableRemoteObject.narrow(o, AdviceHome.class);
Advice advisor = home.create();
System.out.println(advisor.getAdvice());
} catch (Exception ex) {
ex.printStackTrace();
} // end of try|catch
} // end of go
} // end of class
