Tag customizada

Olá pessoal!

Estou desenvolvendo minha própria tag. E ela não está aceitando delimitadores (Expression Language) gostaria que vocês me ajudassem segue a seguir o código.

Classe Taglib

package br.com.tpd.taglib; 

import java.io.IOException; 
import java.util.Collections; 
import java.util.Iterator; 
import java.util.List; 

import javax.servlet.jsp.JspException; 
import javax.servlet.jsp.tagext.SimpleTagSupport; 

import br.com.tpd.to.UsuarioTO; 

public class TaglibGrid extends SimpleTagSupport{ 
   /** 
    * 
    */ 
   private static final long serialVersionUID = 1L; 

   private List listaUsuario; 
    

   public List getListaUsuario() { 
      return listaUsuario; 
   } 



   public void setListaUsuario(List listaUsuario) { 
      this.listaUsuario = listaUsuario; 
   } 
    
   public void doTag() throws JspException, IOException { 
       
      if(listaUsuario.size() &gt 0){ 
         Collections.sort(listaUsuario, UsuarioTO.ORDER_BY_NOME); 
      } 
       
      //StringBuffer sb = new StringBuffer(); 
      Iterator<UsuarioTO> it = listaUsuario.iterator(); 
      while (it.hasNext()) { 
         UsuarioTO usuarioTO = (UsuarioTO) it.next(); 
         /**sb.append("<label for='" + usuarioTO.getNome() + "'>" 
               + usuarioTO.getNome() + "</label>"); 
         sb.append("<label for='" + usuarioTO.getCpf() + "'>" 
               + usuarioTO.getCpf() + "</label>");*/ 
            //getJspContext().setAttribute("usuario", usuarioTO); 
         getJspBody().invoke(null);       
      } 
   } 

    
}
