I am running the program by Scott in the server/default/deploy rather than in a new create howto server.
problem in finding the authintication question is :
where to keep the server file auth.conf. I placed it in default/conf and both tutorial.ears 1 and 2 in the default/deploy. they deploy, access the client file and throws error to not dind the source file for authintication.
if anyone is ready that I zip my program to him to check, i am so grateful.
