comet timeout has expired after 10000ms - one resolution that worked for me #16

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Write your own code using the chat example
2. Use net.zschech.gwt.comet.server.CometServlet in the web.xml
3. Navigate to the comet servlet directly in a browser - you can see 
sun.InstantiationException

What is the expected output? What do you see instead?
... comet timeout has expired after 10000ms

What version of the product are you using? On what operating system?
GWT 1.7 , Windows Vista, JDK 1.6

Please provide any additional information below.

No need to resolve  - this is just to help others facing a similar situation. 

One possible reason is : the net.zschech.gwt.comet.server.CometServlet is 
abstract, and the servlet is not instantiated.

By using an own impl of the abstract class in web.xml : the instantiation error 
and the timeout expired error both seems to go away. At least it worked for me.

Is it not fixed currently? I see in sources that CometServlet is _not_ abstract 
(or its state is changed in runtime or some other way?). However, I get this 
error every time.

http://code.google.com/p/gwt-comet/source/browse/trunk/src/net/zschech/gwt/comet
/server/CometServlet.java

Anyway, I'll try this trick.

Not helped :(

Also, I recently get this exception when I log in from another browser

Caused by: java.io.IOException: Broken pipe

I have created an issue 20 on it.

(No, currently navigating comet servlet do not causes the instantiation error)
