In this ‘How to?’ series of posts, I am talking about different hooks and steps to create hook in Liferay 7/DXP.

In case you have question why you need to implement JSP hook then here is the answer.
hook can help to override a behaviour of out-of-the box portlet’s user interface. For example, you want to display some caution message on Liferay login page, you can override login.jsp using hook.

Creating a jsp hook is most straightforward and easy among other hook types. In this post, I have taken example to override login.jsp of login portlet. Following are the steps to create hook in Liferay 7/DXP.

With this you successfully created JSP hook for Liferay 7/DXP and its ready to deploy. Hope you find these ‘How to? ‘series of posts useful. Please try the steps mention in blog and keep learning!
