Hi, Firstly thank you for helping me out, i just followed the example. It works fine But i have a doubt, when kabir is set as student, it works as expected, but when i change the role as "teacher". the result is same, it is giving error for division and it does subtract operation fine. My understanding is that the error which gives when kabir is student on division operation should happen for subtraction when role is configured as "teacher"(roles.properties). In this sense roles are not picked from roles.properties at all and then even in the user.properties what is the point of entering the default password (which is the correct password, which is again repeated in the client.java) Thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4199149#...
