HFE - Advice Client App

[Santosh Ramachandrula]

Hello Guys,
I am trying to run the AdviceApp enterprise bean. The code compiles but when I run the AdviceClient I get the following errors.....
using SUN APP SERVER 8.0
I looked around the net and found that JSDK has to be consistent on the machine so I uninstalled JSDK/J2EE SDK on my machine and re-installed everthing (even the app server). Now the JSDK version is consistent
java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b04)
Java HotSpot(TM) Client VM (build 1.4.2_04-b04, mixed mode)
This did not fix the error..

Any help would be appreciated....

Here's what I used to run the client, FWIW:

cd \ejbbook\projects\advice
rem java 
rem -cp 
rem c:\j2sdkee1.3.1\lib\j2ee.jar;
rem (removed) c:\j2sdkee1.3.1\lib\locale;
rem (removed) c:\j2sdkee1.3.1\lib\cloudscape\cloudclient.jar;
rem c:\ejbbook\projects\advice\AdviceAppClient.jar;
rem c:\ejbbook\projects\advice
rem AdviceClient
java -cp c:\j2sdkee1.3.1\lib\j2ee.jar;c:\ejbbook\projects\advice\AdviceAppClient.jar;c:\ejbbook\projects\advice AdviceClient
pause

Here's what I have for the go method. It has a bit more than what you find in the book WRT initial context. Sometimes I find if I just start trying different things, something will fall-out...

public void go() {
try {
//Context ic = new InitialContext();
//Object o = ic.lookup("Advisor");
// set up a hashtable that contains enough information
// to obtain an InitialContext from the J2EE server
java.util.Hashtable prop = new java.util.Hashtable();
// here's the context factory's class name
prop.put(Context.INITIAL_CONTEXT_FACTORY,
 "com.sun.enterprise.naming.SerialInitContextFactory");
// here's where the JNDI (naming) server is running
prop.put(Context.PROVIDER_URL, "localhost:1050");
// now get the context
Context initial = new InitialContext(prop);
// look up the EJB's home interface
Object o = initial.lookup("Advisor");

AdviceHome home = (AdviceHome) PortableRemoteObject.narrow(o, AdviceHome.class);
Advice advisor = home.create();
System.out.println(advisor.getTheMessage());
} catch (Exception ex){
ex.printStackTrace();
}
}

Good luck.
