Re: Ways to catch server side exception when using request factory?

Hello,

the 
DefaultExceptionHandleris
 not doing much. As you can see it only sends the message over the wire.
I think you should hook in your own implementation of an ExceptionHandler.

My ExceptionHandler, for example, sends the exception class over to the 
client, too. I don't know how far you can go (sending the whole stacktrace 
or sth.).

To use it you also need to extend RequestFactoryServlet and pass your own 
ExceptionHandler implementation in the constructor.

public MyRequestFactoryServlet() {
super(new MyExceptionHandler());
}

and add this Servlet to your web.xml for sure!

Regards
Alex

Ways to catch server side exception when using request factory?

[July]

hi all:
 I'm using RequestFactory to do B-S communication, usually the server throw 
an exception that i didn't catch, at the client side there will be an pop-up 
dialog indicating the server error, and from the exception stack, all are 
client side trace, and the message is "server error", so i have no way to 
know which method at server-side was throwing(there are more than one 
gwtrequest at one time), debugging this problem cost me much time, I was 
wondering if there a way to catch/show/debug server-side exception so i can 
get the problem immediately. 

Thanks in advance.
