Not really.
I stumbled upon this doubt when developing my application.
I have a List of Principals on my session. The first element is a
UserPrincipal and the rest are RolePrincipal.
What I want is to simply have in a JSP:
Welcome, USERNAME
And I want to retrieve USERNAME from that list. Which, in Java, is something
like Principals[0].getName()
or iterate through the principals List, see if the Principal is of instance
UserPrincipal and, if true, return the current principal's name.
On a general idea, I'm trying to find:
1) How to retrieve an item from a List using OGNL
2) What's the best approach for getting users info on JSP pages, either:
a) Getting them like <s:property id="assert"
value="[EMAIL PROTECTED]@getRequest().userPrincipal.name}"
/>
b) Developing a custom JSP tag to get these kinds of information (name,
email, etc). This would also be an exercise, as I have never developed a
custom JSP tag library.
So, any feedback on questions 1) and 2) would be great!
