Struts and JSON

What is Struts?

Struts is a popular open source framework from Apache Software Foundation based on MVC (model-view-controller) architecture. Though there are many other MVC frameworks available like Spring MVC, JSF in the market to develop web applications, Struts has retained its popularity because of its simple architecture and low learning curve. 

What is JSON?

JSON stands for Java Script Object Notation. It is a light weight data-interchange format using which we can easily parse and generate data. It is language independent, yet it uses popular object oriented convention.  Slowly and slowly it is getting accepted by the software industry as a formidable challenger to XML, the other popular format.
