Hello,

I want to authenticate a user's id and password.

1. The user enter the id and password in a Jsp.
2. jsp directed the request to a servlet
3. Servlet create an instance of session bean and
call one of its method "validate user"
4. Validate user method is creating an instance of "User Entity
bean" for verification and returns true or false.

My question is " is there any other alternative to Entity bean (other than
Hibernate) to verify user e.g Can I do it writing JDBC code?
if yes , where should i write the JDBC code, in another session bean
or in a simple DAO Java class?

Yes you can use anything that can access a database or even some other means, if the data isn't in a database.

If you use JDBC, I would definitely put it in a seperate DAO POJO Java class.

For another example, say you used JBoss and Tomcat, with JBoss you can create a Security Domain that uses a simple properties file, database, or LDAP, then have your WebApp use that Security Domain and you are set.

How about transaction processing? SQLException is enough to take care of transaction in a multiuser environment?
