Hi,

I use vraptor and code from this https://github.com/IvoSestren/vraptor-freemarker/ project for work with Freemarker templates. I have following controller:

package com.tlogica.cyrillicexperiment.controller;

import br.com.caelum.vraptor.Controller;

import br.com.caelum.vraptor.Result;

import br.com.sestren.vraptor.freemarker.FreemarkerResult;

import com.tlogica.cyrillicexperiment.dao.PersonsDAO;

import com.tlogica.cyrillicexperiment.model.Persons;

import java.util.HashMap;

import java.util.List;

import java.util.Map;

import javax.inject.Inject;

/**

* @author tschulev

@Controller

public class PersonsController

{

@Inject

private PersonsDAO dao;

@Inject

private Result result;

public List<Persons> list() {

return dao.listAll();

}

public void form() {

}

public void all() {

Map variaveis = new HashMap();

variaveis.put("personsList", dao.listAll());

result.use(FreemarkerResult.class).addVariables(variaveis).render();

}

public void add(Persons person) {

dao.add(person);

}

When i request http://localhost:8080/TryFreeMarkerFramework/persons/all I have this exception:

Warning: StandardWrapperValve[default]: Servlet.service() for servlet default threw exception
