Hi Chihab, It looks like there are general issues with your configuration when listening on sockets.
Given you're on Linux, I can't imagine it to be permission issues. Have you tried rebooting? Do you know if any of your other apps successfully listen on a port? Could you try a quick Java sample to listen on a port? For example http://java.sun.com/docs/books/tutorial/networking/sockets/clientServer.html. jason On Sun, Mar 21, 2010 at 5:58 PM, Chihab Otmani <[email protected]> wrote: > Hi all, > > I've got the following errors when running the development mode code > server as described in this tutorial: > http://code.google.com/webtoolkit/doc/latest/tutorial/create.html, > either using eclipse or webAppcreator ant. > > When using Eclipse, the following message is displayed in the > console : > "Could not connect to remote UI listening at localhost:52134.
