使用hibernate开发一个小程序，在运行一段时间后，出现OutOf...

出现OutOfMemoryError异常，我已经在操作数据库的时候都关闭了session，哪个大哥能告诉我问题在什么地方呢？

能不能把你的程序代码贴出来？

public Vector getList(String times,String timee,String inftypeid,String dest_nbr) throws HibernateException
  {
    Vector vec=new Vector(10,2);
    Iterator it = null;
    beginTransaction();
    String queryString = "select DispenseMobileWaits from DispenseMobileWait as DispenseMobileWaits ";
    String substr="";
    if (times != null)
      substr += " DispenseMobileWaits.moTime>=:times and";
    if (timee != null)
      substr += " DispenseMobileWaits.moTime<=:timee and";
    if (inftypeid != null)
      substr += " DispenseMobileWaits.infTypeId=:inftypeid and";
    if (dest_nbr != null)
      substr += " DispenseMobileWaits.destNbr=:destbr and";
    if (!substr.equals(""))
    {
      queryString+=" where "+substr.substring(0,substr.length()-3);
    }
    Query query=session.createQuery(queryString+" order by DispenseMobileWaits.moTime ");
    if (times != null)
      query.setString("times",times);
    if (timee != null)
      query.setString("timee",timee);
    if (inftypeid != null)
     query.setString("inftypeid",inftypeid);
    if (dest_nbr != null)
      query.setString("destbr",dest_nbr);
    it=query.iterate();
    while (it.hasNext())
    {
      DispenseMobileWait dmw=(DispenseMobileWait)it.next();
      String[] stemp={"","","","","","","","","","","",""};
      stemp[0] = dmw.getSpCode();
      stemp[1] = dmw.getInfTypeId();
          stemp[2] = dmw.getReplyType();
          stemp[3] = dmw.getAcctNbr();
          stemp[4] = dmw.getDestNbr();
          stemp[5] = dmw.getServiceCode();
          stemp[6] = dmw.getInformationId()+"";
          stemp[7] = dmw.getFeeType();
          stemp[8] = dmw.getFeeCode();
          stemp[9] = dmw.getMsgContent();
          stemp[10] = dmw.getMsgPri();
          stemp[11]=dmw.getMoTime();

          vec.addElement(stemp);
    }
    endTransaction(false);
    return vec;
  }

帮帮忙撒

不太明白你这段代码要完成的工作

这段代码也不太完整，你肯定是这段代码的问题么？
