REST on Struts2 - DAO - Service

[Frans Thamura <fr...@meruvian.org>]

hi all

we create an example using Struts2-Spring-Hibernate, using Spring way,
DAO-Services

this is the SVN

http://ugforge.gunadarma.ac.id/svn/cimande/branches/rest-struts

the project run perfectly

but we use this package for @Services and @Transactional

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

my idea to remove all depedency with Spring

any idea to replace this code?

this is the full code

/**
 * PersonServiceImpl.java
 *
 * Created on 01 Agu 2010 13:07:24
 */
package org.blueoxygen.cimande.example.geneology.service;

import java.sql.Timestamp;
import java.util.List;

import org.blueoxygen.cimande.example.geneology.Person;
import org.blueoxygen.cimande.example.geneology.dao.PersonDAO;
import org.blueoxygen.cimande.security.SessionCredentials;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

personDao.persist(c);
 }
}

personDao.remove(temp);
 }
}
