getting error- cannot instantiate class

Currently Being Moderated
I am getting the following error. I hv created the HosLogin.java class and jsf page which accept user id and password. HosLogin takes user_id and password as parameters. When i get this error, i close my web logic server and then again i run my jsf page and i submit login id and password, it is logged in.
But i dnt understand why i get this error some time. Closing server and running again it, is not a proper solution I think.
So wht is the mistake there, if any?
pls advice me!!!!!!!!
