經過hibernate生成表的測試代碼:sql

package com.xjz.jbpm.db;數據庫

import org.hibernate.cfg.Configuration;
import org.junit.Test;api

public class CreateDB {

@Test
public void test(){
Configuration configuration = new Configuration();
configuration.configure("jbpm.hibernate.cfg.xml");
configuration.buildSessionFactory();
}
}session

 

JBPM4.4的API測試代碼:app

package com.xjz.jbpm.pd;

import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream;
import java.util.List;
import java.util.zip.ZipInputStream;

import org.jbpm.api.Configuration;
import org.jbpm.api.Deployment;
import org.jbpm.api.ProcessDefinition;
import org.jbpm.api.ProcessEngine;
import org.junit.Test;
