Maybe it has something to do with the way I am invoking the servlet. What
is the correct way? These I have tried:

 

http://localhost:8080/examples/ChatServlet

http://localhost:8080/examples/ChatServlet?action=openchat

http://localhost:8080/examples/chat.jsp

 

Which (if any) is correct? All produce the same exception.

 

Thanks,

Subject: Grizzly Comet hasn't been registered

 

I am trying to implement the chat example that Jean-Francois used in his
blog but I get this exception in the same place that other people have
reported it in the past (namely cometContext.addCometHandler(handler); in
doPost()) only I have checked that the context used to invoke the servlet is
the same as that in its mapping configuration. I am using the latest
Grizzly.

 

Are there other possible reasons for getting this exception? The servlet
mapping is "/ChatServlet" and the code to register it is:

 

        contextPath = config.getServletContext().getContextPath() +
"/ChatServlet";

 

The chat.jsp used to invoke the servlet has:

 

<frameset>

  <iframe src ="/examples/ChatServlet?action=openchat" name="CometChat"
width="100%" scrolling="auto"> </iframe>

  <iframe name="post" src="post.jsp" width="100%" scrolling="no"/>

</frameset>

 

 

Any ideas?

 

Thanks,
