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() > 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);
}
}
}
