Java Spring with Hibernate Integrating Hibernate with Spring Configure Spring for Hibernate

Stuck on Task 3/3 on Configure Spring with Hibernate Challenge...

I can't figure out what code is required in Task 3 of this exercise. When I run it, it tells me: "Oops! It looks like Task 2 is no longer passing." Except when I go back to Task 2 and re-run that code without changing anything, it still passes.

My code should be attached to this post. Any help or guidance would be appreciated.

com/teamtreehouse/contactmgr/config/DataConfig.java 
package com.teamtreehouse.contactmgr.config;

import org.apache.tomcat.dbcp.dbcp2.BasicDataSource;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
import org.springframework.core.env.Environment;
import org.springframework.core.io.ClassPathResource;
import org.springframework.core.io.Resource;
import org.springframework.orm.hibernate5.LocalSessionFactoryBean;

import javax.sql.DataSource;

@Configuration
@PropertySource("app.properties")
public class DataConfig {
  @Autowired
  private Environment env;

  @Bean
    public LocalSessionFactoryBean sessionFactory() {
      LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
      sessionFactory.setPackagesToScan(env.getProperty("com.teamtreehouse.contactmgr.model"));
      sessionFactory.setDataSource(dataSource());
      return sessionFactory;
    }

  @Bean
    public DataSource dataSource() {
      BasicDataSource ds = new BasicDataSource();

      // Driver class name
      ds.setDriverClassName(env.getProperty("giflib.db.driver"));

      // Set URL
      ds.setUrl(env.getProperty("giflib.db.url"));

      return ds;
    }
}
app.properties 
giflib.db.driver = org.h2.Driver
giflib.db.url = jdbc:h2:mem:contactmgr

Remove "env.getProperty" from 

sessionFactory.setPackagesToScan(env.getProperty("com.teamtreehouse.contactmgr.model"));

There is no such property. It is simple string that you should set:

sessionFactory.setPackagesToScan("com.teamtreehouse.contactmgr.model");

Should work...
