WebSphere provides an implementation of the standard portal tag libraries to help developers in their web development tasks. You would see this in a lot of the JSPs that come with the IBM themes as well as any existing portlet project you may work on.
Provides the following constants for use in the page
<%= wpsBaseURL %>
<%= wpsDocURL %>
The documentation is a bit unclear from the IBM sites stating that this tag “Defines a set of objects…” but it only has the following available:
<%= escapeXmlwriter %>
For more information on using escapeXmlWriter, you can refer to java.io.Writer abstract class.
