Class BaseTag

java.lang.Object
  javax.servlet.jsp.tagext.TagSupport
      com.cc.framework.taglib.util.BaseTag

All Implemented Interfaces:

javax.servlet.jsp.tagext.IterationTag, javax.servlet.jsp.tagext.JspTag, java.io.Serializable, javax.servlet.jsp.tagext.Tag

public class BaseTag

extends javax.servlet.jsp.tagext.TagSupport

Tag handler for the base tag. The <util:base> tag creates a html <base href="...."> element. The tag automatically sets the context root, so you can write <util:base> instead of <base href="http://localhost:8080/contextRoot/;"> if the context root of your application points to "contextRoot". The tag also sets automatically the used protocol (http, https). So you can deploy your application under differnt names, without changing the <base href="...."> element.
