@i wil start jboss server and my application working praperly in that day only,but i wil login next day cant login page..it go to error page(I am isong Jboss6.0 and jsf2.0)
How to solve this issue
Can't really guess based on what you have mentioned so far. You'll have to take a look at the logs (server.log) and see what's wrong or maybe debug the application.
