在HTML中按下一页或者上一页的时候有如下代码：
<logic:equal name="page" property="hasNextPage" value="true">
<html:link page="/List.do?action=nextPage">
nextPage
</html:link>
</logic:equal>
<logic:equal name="page" property="hasPreviousPage" value="true">
<html:link page="/List.do?action=previousPage">
PreviousPage
</html:link>
</logic:equal>
然后在Action中作如下处理：  
  String currentPage = request.getParameter("currentPage");
  HttpSession session = request.getSession(); 
  EmployeeForm employeeForm = (EmployeeForm) form;
  String queryString = null;
  String queryCon = null;
  String action = employeeForm.getAction();
  List list = new ArrayList();
  PageBean pb = null;
  EmployeeDao employeeDao = new EmployeeDao();
  if(action == null || action.equals("null")){
   int totalRows = employeeDao.getTotalRows();
  
    pb = new PageBean(totalRows);
    session.removeAttribute("page");
    queryString = employeeForm.getQueryString();
    queryCon = employeeForm.getQueryCon();
    session.setAttribute("queryString",queryString);
    session.setAttribute("queryCon",queryCon);   
    list = employeeDao.getAllEmployee(queryString, queryCon,
      String.valueOf(pb.getPageStartRow()),
      String.valueOf(pb.getPageRecorders()));
       
  }else if(action.equals("nextPage")){
   queryString = (String)session.getAttribute("queryString");
   queryCon = (String)session.getAttribute("queryCon");      
   employeeForm.setQueryString(queryString);
   employeeForm.setQueryCon(queryCon);
   pb = (PageBean)session.getAttribute("page");
   pb.nextPage();
   list = employeeDao.getAllEmployee(queryString, queryCon,
     String.valueOf(pb.getPageStartRow()),
     String.valueOf(pb.getPageRecorders()));
  }else if(action.equals("previousPage")){
   queryString = (String)session.getAttribute("queryString");
   queryCon = (String)session.getAttribute("queryCon");
   employeeForm.setQueryString(queryString);
   employeeForm.setQueryCon(queryCon);
   pb = (PageBean)session.getAttribute("page");   
   pb.previousPage();
   list = employeeDao.getAllEmployee(queryString, queryCon,
     String.valueOf(pb.getPageStartRow()),
     String.valueOf(pb.getPageRecorders()));
  }
        
        pb.description();
        session.setAttribute("page",pb);        
  request.setAttribute("admin", "admin");
  request.setAttribute("employee", list);
  return mapping.findForward("showlist");
  然后在数据库查询中有如下代码：
/**
*查询总记录数
*/
 public int getTotalRows() {
  int totalRows = 0;
  String sql = "select count(*) from employee";//假设是员工表
  Database db = new Database();
  ResultSet rs = db.executeQuery(sql);
  try {
   while (rs.next()) {
    String id = (String) rs.getString(1);
    totalRows = Integer.parseInt(id);
   }
  } catch (SQLException e) {
   e.printStackTrace();
  }
