package com.mycompany.struts.components;  import javax.servlet.http.httpservletrequest; import javax.servlet.http.httpservletresponse;  import org.apache.struts2.components.component;  import com.opensymphony.xwork2.util.valuestack;  public class anchortag extends org.apache.struts2.views.jsp.ui.anchortag { private static final long serialversionuid = 5811285953670562288l;  protected string token;   public component getbean(valuestack stack, httpservletrequest req,                          httpservletresponse res) {     return new anchor(stack, req, res); }  protected void populateparams() {     super.populateparams();     anchor anchor = ((anchor) component);     anchor.settoken(token);   }   public void settoken(string token) {     this.token = token;   } }
