I'm new to Struts 2 and I'm trying to figure out why my s:if is not working.

If I enter this:

it returns Y.

However, if I enter this:

It returns No.


What am I doing wrong?

The expressions you are using are OGNL expresssions, not Java expressions. The expression "#{session.admin}" is a valid OGNL expression, while "#{session.admin.trim()}" is not.

Thank you for your assistance. However, I changed the code and it still gives me the incorrect response.



Could the problem be that I'm comparing a String to a char? If so, how is this solved?

Thank you for your help! I figured out the problem. I initially set the session variable as a String (session.setAttribute("admin", "Y")). Changing it to a char (session.setAttribute("admin", 'Y')) solved the problem.
