Re: howto add a UDP Listener

The problem is that Sharer  Viewer should be a Java Application that does
not require Installation on the client machine and it has to be available
for all plattforms. So Java Web Start is our choice.

The solution will be part of a GPL-Project so it cannot be based on
commercial products.

 You may want to look at the Java VNC Viewer:

 http://www.realvnc.com/support/javavncviewer.html

 or TightVNC:

 http://www.tightvnc.com/download.html

 it may save you repeating work which has already been done elsewhere.

They are both licensed under the GPL. You can web start enable any  
Java application.


BTW Just in case I am detecting a misunderstanding, Java Web Start is  
not the same thing as a webapp. You don't need Tomcat to 'web start' a  
Java application. Apache HTTPD will do the job just fine.

 Is there a way of telling tomcat to receive UDP Packets and forward
 them to my Handlers?

No.  Tomcat is a server for HTTP requests running over TCP protocol.  You'll 
need to implement your own UDP handler.  You might want to look over this 
thread, which sounds similar to your situation (ignore the last message of the 
thread, which is a hijack):
http://marc.info/?t=11356216962r=1w=2

You might be able to make use of this within your code:

I am just curious what problem the original poster is trying to address?

The approach I would probably take is to make an external proxy  
application that accepts the UDP requests and then submits the data as  
an HTTP request to the web server using a GET or POST request. The  
advantage with this is that it helps keep the webapp focused on HTTP  
and not stuff that doesn't really fit with web server.

 I am working on a Desktop Sharing application that is sending the

Why doesn't the Desktop Sharing application use a reliable protocol (e.g., HTTP

I think you mean why it does NOT use a reliable protocol ... ?

Iit is not that important if some packages are lost in this case and I hope
to gain some performance by using UDP.

Which is what I said:

  Why *doesn't* the Desktop Sharing application use a reliable protocol

 I hope to gain some performance by using UDP.

Simply by eliminating the ACKs?  I think you'd be hard pressed to measure a 
real-world difference.
