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. -- Glynn Clements <glynn.clements@xxxxxxxxxx> - : send the line "unsubscribe linux-admin" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
