Nico, Thanks for your response. However, what will happen to the existing code in the doStartTag of the org.apache.struts.taglib.html.LinkTag? Because I will still need the existing functionality of the org.apache.struts.taglib.html.LinkTag as well !! Should I make a call to the super.doStartTag()?
Please advise. Thanks.
