Send Redirect in Liferay


Today we will discuss how to redirect from a portlet to another portlet which are placed on some other page. For this we need two things:-

1)Portlet Layout Id(plid)
We need the plid of the page where we want to redirect.We can get the plid by the page name as:-
2)Portlet Name
We can get the Portlet name (on which we have to redirect) by clicking on wheel icon of portlet than go to look and feel and than click on advance Styling.




So lets start this step by step:-


Step 1:-Create Liferay Project and Portlet
Inside eclipse IDE Click on File->New->Liferay plugin project and give the project name as send-redirect and click finish. After that Right Click on your project ie send-redirect and click on New than click on Liferay Portlet. Provide class name as Demo and select MVCPortlet and click finish.
