A little more information about this problem would help. Is this an error message displayed in the browser? What were you doing when this happened? If you were accessing an application that you deployed, I would guess that the application created an invalid URL (possibly it meant /proj?method="post" instead). In that case you need to fix the application. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4041116#...
