How to call a bean from a form?

Question

hi all
i want to write a simple bean that checks the login information (userId ad Password) passed to it by a form in my jsp file.
so i think i have to call the setUser() and setPassword() methods of my bean in a single action... how to do it?
I also thought i can do it by calling a JavaScript, by I dont know how....
then, once i get the boolean value (logged) returned from my bean, i can (through jsp) redirect the logged user to another page, or send a message to the non-logged user.
is it a good solution or should I do it with a servlet?
thanx for your answers

Answer 1

u can do it using a servlet or JSP itself. Check the sample code below to see how u can validate using values from form
<%
String username=request.getString("frmUser");
String password=request.getString("frmPassword");
urBean userBean = new urBean(); //Creating instance of ur bean class.
userBean.setUserName(username); //Setting username
userBean.setPassword(password); //Setting password
boolean flag = userBean.validate(); //This functions validates against a database.
if(flag) {
response.sendRedirect("loggedin.jsp"); //redirects to page on successfull login
}else{
response.sendRedirect("error.jsp"); //redirects to error page.
%>
Hope this helps
