Hi Aditi,

Can you put some light on your requirement, and please add some code that you tried to implement this, that will help ranchers to come up with some solution for you.

Thanks,
Shailesh

In userloginaction you can put userName in session(you can get session object from request which is parameter to execute method )if user id & password is validated.
Then in your changepasswrod.jsp you can retrieve it from session (In jsp we are having implicit session object).

Hi Aditi,

you can get help of API for HttpServletRequest on this link.
(you can use getSession() method of HttpServletRequest object.)

for HttpSession you will get at this link.
(you can use getAttribute & setAtttibute method of session object.)

You probably need a type cast here, because return type of getAttribute is Object.



And you should store the value of username

I don't think you need to declare session in jsp, because action is being handled by the action handler class.
What is happening here?

Have you made any change in either of the two codes? And by the way you still have this problem



"user"?? it should be the variable name.

Hi Aditi,

First of all go through getAttrubute() & setAttribute() method of HttpSession object.

in that setAttribute() first parameter is name of attribute and second parameter is object that you want to put in session.

above code will not work because you are setting string "username" in session with name as user.
So if you call you will get String object "username" in reply.

do setting attribute by following code,


and for getting from session

What changes have you made in userloginaction? One more thing I could not figure out what has invalidate got to do with login? Invalidate is typically used when you no longer wish to hold the session, so a typical situation can be when the user logs out. Apart from this have you made any change in the login jsp page?
