how to redirect from prepare() method in struts 2
Hello friends,
I have very little experience in struts 2 I have this typical requirement
where I feel that I have to redirect form the prepare() method when the user
is not logged in (by checking whether some session entries present or not).
Actually I am trying to avoid repetitive session checking redirecting at
the beginning of every action method, for example
public String listUsers() throes Exception
{
//if (session.get(userType) != null
session.get(userType).equals(admin))
//then show the result
//otherwise redirect to the login page
}
public String viewDetails() throes Exception
{
//again code for the same checking
}
so I thought that since the prepare() method is being called every time some
action is being mapped to a method in this class so why not put the code for
checking redirecting inside of prepare
like,
public void prepare() throws Exception
{
//if the user is not logged in
//redirect to the login page
}
But the problem is that I cannot return any string (which I can specify as
result of type redirect-action in the struts.xml file)since this function
has return type void also I could not find any method to redirect forcibly.
So, my question is whether it is possible to redirect form any method which
has not been mapped as an action at all?
if it can be done then how to do it?
Any ideas regarding this problem would really help.
Thanks in advance

It would be much cleaner to put that kind of logic into an interceptor
rather than in a prepare() method. It would cut down significantly on
code duplication.

Wes is right Dave... if the guy wants to buy a book, who are we to discourage it? Your demand will not be affected in the least! Also, I would like to give a shout out to the upcoming Struts 2 in Practice book. I have been reviewing it, and it absolutely rocks!

Can I ask a personal question Dave? Does this have anything to do with your illiteracy? :) P.S. And why are you not finishing your leather bound volume? I already said I would pay in advance!
