2.一下是Action

/* 
* Generated by MyEclipse Struts 
* Template path: templates/java/JavaClass.vtl 
*/ 
package struts.action; 
import java.util.Collection; 
import javax.servlet.http.HttpServletRequest; 
import javax.servlet.http.HttpServletResponse; 
import org.apache.struts.action.Action; 
import org.apache.struts.action.ActionForm; 
import org.apache.struts.action.ActionForward; 
import org.apache.struts.action.ActionMapping; 
import page.bean.DatabaseConn; 
import page.bean.PageResultSet; 
import page.bean.ContactBO; 
import struts.form.LoginForm; 
/** 
* MyEclipse Struts 
* Creation date: 04-02-2008 
* 
* XDoclet definition: 
* @struts.action path="/login" name="loginForm" input="/login.jsp" scope="request" validate="true" 
* @struts.action-forward name="sss" path="/index.jsp" 
*/ 
public class LoginAction extends Action { 
/* 
* Generated Methods 
*/ 
/** 
* Method execute 
* @param mapping 
* @param form 
* @param request 
* @param response 
* @return ActionForward 
*/ 
public ActionForward execute(ActionMapping mapping, ActionForm form, 
HttpServletRequest request, HttpServletResponse response) { 
LoginForm loginForm = (LoginForm) form; 
ContactBO userBO=new ContactBO(); 
//先从业务处理逻辑类中取出数据(ArrayList或Vector格式) 
Collection data; 
try { 
data = userBO.findContact(DatabaseConn.getConnection()); 
//再得到当前页curPage和每页记录数pageSize 
//int curPage = Integer.parseInt((String)request.getParameter("cur_page")); 
int curPage = 1; 
String cur = request.getParameter("cur_page"); 
System.out.println("--------------: "+cur); 
if(cur!=null && cur !=""){ 
curPage = new Integer(cur).intValue(); 
} 
int pageSize=10; 
//然后生成PageResultSet对象 
PageResultSet dataList = new PageResultSet(data, curPage, pageSize); 
request.setAttribute("usersList", dataList); 
return mapping.findForward("sss"); 
} catch (Exception e) { 
e.printStackTrace(); 
return mapping.getInputForward(); 
} 
} 
}

3.以下是显示分页的页面
