In this session i have explained about the importance and role of OGNL and ValueStack in Struts2 Framework. i have explained how OGNL offers the expression language in form tags and type conversion. ValueStack has two parts – Object stack and Context map. ValueStack has access to all the objects created for requests and context map has reference to the request, session and application context maps. I have explained about the syntax used to access the objects and context map objects in Struts 2 Framework.
