I am a newbie to Struts2.Have a few questions related to tag library of struts2.
Q1) I would like to know about <s:action> in strust2. How does it differ from <s:a> tag.
Q2) What is the usage of <s:tree>, <s:treenode>& <s:tabbedpanel>
Q3)To interact with Ajax Model, Struts2 uses Topic. What exactly is a Topic & how does it work?
