Is there a bug in the WebService tutorial for JDeveloper 9i?

Question

In reading through the JDeveloper 9i tutorial for building a web service, the final step generates the DateTimeServiceStub.java, but the testing that follows does not use this class, it uses the DateTimeService class.
I built a Web Service based on the this tutorial and when I test with "MyClass.java" it works fine, but when I try to use "MyClassStub.java" it throws the ClassNotFound Exception below:
java.lang.NoClassDefFoundError: HTTPClient/ModuleException
     at mypackage.RandomQuoteStub.<init>(RandomQuoteStub.java:21)
     at mypackage.RandomQuoteServlet.doGet(RandomQuoteServlet.java:27)
     at javax.servlet.http.HttpServlet.service(HttpServlet.java:195)
     at javax.servlet.http.HttpServlet.service(HttpServlet.java:309)
     at javax.servlet.http.HttpServlet.service(HttpServlet.java:336)
If we are supposed to use the Stub methods, any thought as to why it fails?
If we are NOT supposed to use the Stub methods, any thought as to why they are generated.
(Yes, I am a bit new to Web Service development).
Thanks in advance for any answers,

Hi Richard,
I ran into another problem when I tried to create a web service and call this web service following the tutorial from Oracle9i JDeveloper Release 2.
The following error message occured after I ran DateTimeClient class:
[SOAPException: faultCode=SOAP-ENV:Protocol; msg=Unsupported response content type &quot;text/html&quot;, must be: &quot;text/xml&quot;. Response was:
          &lt;DIV class=Section1&gt;

          &lt;P class=MsoNormal&gt;&lt;B&gt;Problem Report&lt;/B&gt;&lt;/P&gt;
             &lt;/TD&gt;

          &lt;P class=MsoNormal&gt;The Web proxy was not able to authenticate you through
                the authentication server because:&amp;#32&amp;#32&lt;b&gt;General authentication failure due to bad user ID or authentication token.&lt;/b&gt;
                You will not be able to browse the Web through this proxy until your
                credentials can be retrieved and verified.&lt;/P&gt;
             &lt;/TD&gt;

          &lt;P class=MsoNormal&gt;This might be due to transient network problems or due to the
                user&apos;s not being authorized to use this Web proxy.&lt;/P&gt;
             &lt;/TD&gt;
             &lt;/TR&gt;
             &lt;TR&gt;

                      &lt;P class=MsoNormal&gt;Contact your network support team
                              if this problem persists, and provide the team your
                              account information.&lt;/P&gt;
             &lt;/TD&gt;
             &lt;/T

Exception in thread main
Process exited with exit code 1.
By the way, I got the correct information when I tried to load:
(1) http://159.249.94.139:8888
(2) http://159.249.94.139:8888/soap/servlet/soaprouter
which means that oc4j and SOAP server are running properly.
Do you have any idea what went wrong?
Thank you in advance.
