IMPLEMENTATION OF PORTLET

We can implement the portlet by two ways.

1.  Generic portlet: It is build on top of JSR 168 and JSR 286. Can run on any server.

2.  MVC Portlet:  It is Liferay specific. This works on only liferay portal server. (This is not in use as much as generic portlet).

DIFFERENCE BETWEEN GENERIC & MVC PORTLET

  Generic portlet:

     Generic portlet is implemented by the JSR 168 & 286.

    Used to work on any servers.

     Generic portlet provides default implementation for the portlet interface.

MVC Portlet:

    MVC portlet is implemented by the liferay server.

     Used to work only on liferay portal server.

    MVC portlet extends from Generic portlet and add to it several convenience methods.
