[Liferay][JSTL] Adding JSTL support for liferay portlet.

Hi,

It a good practice to use JSTL for your portlets jsp rather than using scriptlets. This blog will show how to add support of jstl for your portlets. Follow these simple steps -

1. Add portal-dependency jars to lifeary-plugin-package.properties file

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

2. Add portal-dependency tlds to liferay-plugin-package.properties file.

portal-dependency-tlds=\
    liferay-portlet_2_0.tld,\
    liferay-ui.tld,\
    fn.tld,\
    c.tld,\
    fmt.tld

3. In the JSP add taglibs.

<%@ taglib uri="http://java.sun.com/jstl/core_rt" prefix="c"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt" %>

4. And now you can use <c:xx />, <fn:xx/> and <fmt:xx> and similarly other taglibs.

Hope this helps.

Until next time. C Ya
