connection problem to the X server
Dear all,
I have a web application developed using JSPs, that needs to connect to a X server to show a statistics graphic. The logs when I issue an "xhost + localhost" of Tomcat gives this :
Xlib: connection to "localhost:0.0" refused by server
Xlib: No protocol specified
xhost: unable to open display "localhost:0.0"
When I issue a xhost to a different box, it doesnt fail. I have been googling a bit, I got the impression that using xhost is not safe, and it is better to use xauth. Anyway I still dont know how to fix this.
Regards and sorry for my english
Miguel

If the X server is already using X authentication, it won't allow xhost to connect. Run xhost without arguments; if you get the response:
$ xhost access control enabled, only authorized clients can connect
then the X server is using X authentication. In that case, you will have to copy the necessary authentication credentials into a file which can be read by Tomcat, and set the environment variable XAUTHORITY to refer to that file. See "man xauth" for details.
