How to extend any Liferay Portlet

[Yogesh Prabhu, modificado hace 13 años.]

Hi,

I am working with Liferay 5.2.3 Community edition and Liferay 6 Community edition..
Are there any basic steps to follow to extend any Liferay portlet..??

If i want to extend document Library portlet or for that matter any portlet, what are the steps that should be followed..??

Any kind of ideas or suggestions are welcome..

Thanks in advance..!!!

Hi Yogesh, one easy way (which requires no programming) is by using Custom Fields in the Control Panel.

If the customizations are more complex, Amos wrote a good blog on how to go about adding customized logic.

Hi,

Going by this example what service-type do I override to create Hook for Liferay RSS portlet?

You cannot use their example, it's from 2010 and therefore quite old and out of date.
