How to add jstl to a Liferay portlet?

Question

I have been looking here in SO and other places and I have not found the exact answer to this question. So here goes:

What is the best way to add support in my Liferay portlets to use JSTL tags?

Of course, I have found generic answers about how to add a taglib to a web app, but not specifically for Liferay.

Answer 1

You just need to add jstl-api.jar and jstl-impl.jar to your portlet dependencies.

These jar files are already in Liferay webapps/ROOT/WEB-INF/lib.

So just add this to the file liferay-plugin-package.properties:

portal-dependency-jars=jstl-api.jar,jstl-impl.jar
