How to pass the current logged in username to struts2 action from spring security 3

[Omar Ngarigari]

Hello,

Thanks in advance. I have an application that uses Spring Security 3 + Struts2. 
The integration works just fine. I can login without an issue. However, I would 
like to get the username in the Struts2 action class so that I can display in 
the Struts2 tags jsp pages.
