I know about the actionUrl and renderUrl
But I want to know Where I can use exactly ?
when we go through actionURL and renderURL?
Hi Archana!..
There are three different types of portlet URLs:
1.Render URL —Used to ask a portlet instance to generate markup (like HTML,XML, WML) based on its current state. For example This URL you can use when if you want to go to next jsp page from current jsp page with out executing action class (linking hyper link etc). and also one more example if you want execute render method of action class you can use Render URL.
2.Action URL —Used for action processing, which results in a state change on the server. The request sent to the portlet by an action URL is referred to as an
action request. For example if you want to submit some form to action class or if you want process your request, you go for action URL. After completing the execution of action method, render method will execute once again.
3.Resource URL —Used to render content or retrieve resources (like image files).Depending upon the application requirement, a resource URL may be used for
updating application state. The request sent to the portlet by a resource URL is referred to as a resource request. For example if you want some resource from server like(Document or some download things) can go for Resource URL.
I hope so this may clear your doubt.
