WebSphere Portal supports the use of tags from the JSP Standard Tag Library (JSTL), which originated from the Java Community Process to promote the adoption of common JSP tags that would be available in all compliant JSP containers.

Portal themes, skins, and screens can retrieve translated text by using the fmt tags from the JSP Standard Tag Library (JSTL). This method is preferred over using the <portal:text/> tag from the engine tag library, which is deprecated. The following tags from the JSTL tag library are used to retrieve translated text:

The underlying getLocales() method of the HTTPServletRequest is overwritten to return the language preference in the user profile, if available.

Support for the JSTL tag library is provided by WebSphere Portal. To use the JSTL tags, the following directive must be provided in the JSP. 

<%@ taglib uri="http://java.sun.com/jstl/fmt" prefix="fmt" %>

The following example shows how the HTML help link in the toolbar can be created using the JSTL tags for the link text. 

<%-- help button --%>

<td class="wpsToolBar" 
    valign="middle" 
    align="<%=bidiAlignRight%>" 
    nowrap="nowrap">

   <a class="wpsToolBarLink" 
      href='<%= wpsDocURL %>/InfoCenter/help/index.html' 
      target="...

        <fmt:setBundle baseName="nls.engine">
           <fmt:message key="link.help"/>
        </fmt:setBundle>
   </a>

</td>

Test this code by changing the language preference in the portal user profile and logging back in to the portal.
