java实现的可配置的工作流引擎,采用jsp+javabean实现

				package com.hongsoft.res.pojo;
				
				import org.hibernate.Session;
				
				import com.hongsoft.res.database.ResHibernateFactory;
				
				public class OrgUnitElement extends ResObjectElement {
				  private OrgUnit ou = null;
				  public OrgUnitElement(ResObjectElement element){
				    super(element);
				  }
				  /**
				   * 获取该Element相应的组织对象
				   * @return OrgUnit
				   */
				  public OrgUnit getOrgUnit(Session session)throws ResException{
				  	try
					{  	
				    if(ou==null)
				      ou=ResHibernateFactory.createOrgUnitHibernate().getOrgUnit(session,this.getID());
				   	}
				  	catch(Exception e)
					{
				  		e.printStackTrace();
					}
				    return ou;
				  }
