Re: howto add a UDP Listener
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.

Re: howto add a UDP Listener
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. sebastian 2009/9/13 Caldarale, Charles R > > From: Sebastian Wagner [mailto:seba.wag...@gmail.com] > > Subject: Re: howto add a UDP Listener > > > > I am working on a Desktop Sharing application that is sending the > > Desktop Images over UDP to Tomcat. > > Why doesn't the Desktop Sharing application use a reliable protocol (e.g., > HTTP over TCP) to talk to Tomcat? > > - Chuck > > > THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY > MATERIAL and is thus for use only by the intended recipient.

Re: howto add a UDP Listener
Thanks for your answers. I am working on a Desktop Sharing application that is sending the Desktop Images over UDP to Tomcat. As this is quite time-critical I need to integrate the UDP-handler into my webapp. It seems like using MINA does solve my Issues. thanks, sebastian 2009/9/13 Andre-John Mas > > On 13-Sep-2009, at 14:19, Caldarale, Charles R wrote: > > From: Sebastian Wagner [mailto:seba.wag...@gmail.com] >>> Subject: howto add a UDP Listener >>> >>> 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.

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.
