org.apache.struts.taglib.html Class BaseTag

java.lang.Object

  +--javax.servlet.jsp.tagext.TagSupport
        |
        +--org.apache.struts.taglib.html.BaseTag

All Implemented Interfaces:: java.io.Serializable, javax.servlet.jsp.tagext.Tag

public class BaseTag
extends javax.servlet.jsp.tagext.TagSupport

Renders an HTML element with an href attribute pointing to the absolute location of the enclosing JSP page. This tag is only valid when nested inside a head tag body. The presence of this tag allows the browser to resolve relative URL's to images, CSS stylesheets and other resources in a manner independent of the URL used to call the ActionServlet.
