RE: ClassCastException Error in a Java Servlet

Barry,
I tried that and now get the following:

Error: 500
Location: /PVSW/servlet/hello
Internal Servlet Error:

I'm not sure what to do now.  I'll be looking up the NullPointerException.
Thanks,
Eric

Put the html form in your webapps/PVSW  folder.  Lets assume you call it
hello.html.  If your program is called Hello.class, then the action
statement in the form tag of hello.html should be action="servlet/Hello".
The Hello.class should be in the webapps/PVSW/WEB-INF/classes folder.  Then
try executing the http://myas400.com:8000/test/hello.html.
