Tag Libs

JSP pages in the portal can use custom tag libs by doing the following:

Package the class files that implement the tag lib in the lib or classes directory of the PAR file's PORTAL-INF folder.
Add a directive to any JSP file that references the tag lib's .tld file, as follows:

Syntax Syntax

<%@ taglib uri="<uri>" prefix="<prefix>" %>

End of the code.

The following shows the possible formats for the uri attribute above:

URI	Description
Path of `.tld` file	The path to the tag lib's `.tld` file, relative to the JSP file.
Alias to `.tld` file. The alias can be provided with the prefix `prt:taglib:`	An alias for the path to the `.tld` file is defined by a `<property>` element in the `<component-profile>` element. The value of the property is provided with the following format: `/SERVICE/<portal app>/<path to .tld file>` where the path to the `.tld` file is relative to the folder that contains the portal application's public Web resources. For example, an alias for the portal's HTMLB tag lib must point to: `/SERVICE/com.sap.portal.htmlb/taglib/htmlb.tld`
