struts is a open source implementation of MVC design pattern to develop large scale web applications.Struts framework makes it easier to design realible scalable web applications in java.Struts is not only thread safe but also thread dependent.It instantiates each action once and allows others to be threaded through the original object.Struts reduces the for redundant jsp's.ActionForm stratagy reduces the need of sub class hierarchy.

Struts is a light weight package.It consists of 5 core packages and 5 tag lig directories.

Hi

If the client comes to the struts application then the flow of control will be..

1) The request received by hte ActionServlet which is the default Controller in Struts...

2)ActionServlet then call RequestProcesser.preProcess method to find the formbean populate the value to it validate the values..

3)Once the validating has finished the ActionServlet's RequestProcesser.preProcess() method call Action class's execute method where the original business processing begins....

4)The action class process the method and reurns the result to ActionServlet.....

5)In returning the Action class provides the key to the corresponding ActionServlet to determine the reult acqiured fromprocessing will be diplayed...

6)The ActionServlet then display results to client using the key provided by the action class..

Hope You understand well..!!

Bye!
