Question

 public Users loginUser(String username,String password)
{
    Users user;
    org.hibernate.Transaction tx = session.beginTransaction();
    Query q = session.createQuery("from Users as users where Username ="+ username + " && Password = " +password);
    user = (Users) q.uniqueResult();
    return user;
}

I am trying to return the user who is trying to login but it gives me an error from the line which is calling the method above.

org.apache.jasper.JasperException: An exception occurred processing JSP page /loginlogout.jsp at line 21

I think you can try below query:

Query q = session.createQuery("from Users as users where users.Username=:username and users.Password=:password") ;
