how to make method for hibernate read data from database???
I'm missing the code for your User and there will very likely be a bunch of "caused by" stacktraces in your exception which will point you to the problem (check your logs and not just the tapestry error page). You seem to be mixing your Service layer, DAO layer and model layer all into one here. Also you are caching your users in a Map and I can't seem to find the trace to you actual hibernate session calls. I'm trying to trace those as pretty certain your problem lies there.
The session.get(UserBean.class, userName); takes the primary key of the UserBean, but in your case UserBean seems to be a Service without any mapping associated with it. Also, generally primary keys are Long's. To retrieve a UserBean by its username have a look at the hiberante criteria documentation.
The exception you are seeing might happen when you call get with a null primary key. But you'll need to post the full stacktrace for me to be sure.
I would advice you to have a good look at the tapestry hibernate examples as you are setting yourself up for quite an unreadable project like this.
Good luck, Joost
