Hello,
Is it possible to do "if then else" type of processing using Struts Logic
tags? I don't see anything in the Struts Logic tags documentation at this
link http://struts.apache.org/struts-doc-1.2.7/userGuide/struts-logic.html
Here's my situation:
1) I want to put in some logic in all my jsps to check if a user has
authenticated.
2) If user has not then I want the page to display a simple message saying
that login is required and include a link back to login page.
3) If user HAS authenticated I want the page to display the normal "stuff"
(e.g. content, struts form, etc) that the page is intended for.
4) Upon valid login, a user object is placed in session and it will have a
boolean property called "authenticated"
I know I could do something like this
...
<logic:equal name="user" property="authorized" value="false">
<h3>You must be logged in to view this page. Please login <a href=
"login.jsp">here</a></h3>
</logic:equal>
<logic:equal name="user" property="authorized" value="true">
Thank you for loggin in... Normal "stuff" for this page
</logic:equal>
One of the problems is that I also need to check if the user session object
is null because a user could have tried to go directly to an "internal"
(after login page) page using a bookmark. How can I check for the presence
of an object in the session?
Any help would be greatly appreciated.
Thanks.
David.
