Hi,
I want to create my own custom tag library in Liferay. The custom tag library have input parameter as categoryId and and from that categoryId I need to get documents related to it.
Which plugin I have to use to create own custom tab liberary. Is it hook or portlet ? And how to develop it.

Thanks,
Sandip Patel

A tag library is, at it's heart, a bunch of java classes along with a TLD descriptor - effectively just a jar.

You can deploy your jar using an EXT plugin to share or with each dependent plugin to use only where needed.

Hi,

Create a dir in WEB-INF with name tags (WEB-INF/tags).
Create files with extension .tag. Example: my-taglib.tag
In tag file, import:

&lt;%@ taglib uri="http://java.sun.com/portlet_2_0" prefix="portlet"%&gt;
&lt;%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%&gt;
&lt;%@ taglib uri="http://liferay.com/tld/aui" prefix="aui"%&gt;
&lt;%@ taglib uri="http://liferay.com/tld/portlet" prefix="liferay-portlet"%&gt;
&lt;%@ taglib uri="http://liferay.com/tld/theme" prefix="liferay-theme"%&gt;
&lt;%@ taglib uri="http://liferay.com/tld/ui" prefix="liferay-ui"%&gt;

To receiver parameters:

&lt;%@ attribute name="parameter" required="true" type="java.lang.String"%&gt;

To import taglib in jsp file:

&lt;%@ taglib tagdir="/WEB-INF/tags" prefix="prefix"%&gt;

To use:

<prefix:my-taglib parameter="Hello Word" />
