算了。。。。问点实际能解决问题的。。。

[Lie_li]

jsp页面

顶头引用javabean

body里
<%
out.print(geta()+","+getb());
int abc=1
out.print("<a href=/servlet?abc="+abc+">")
%>

javabean文件
get set a,b


JAVA方法文件
引用javabean
getinfo(int i)
if(i!=1)
{
seta(5);
setb(6);
}
else
{
seta(1);
setb(2);
}


servlet文件
不知道该怎么写了

我想的是

除了要跳到jsp外

要调用方法文件把参数给他

我是打算用setAttribute("info",getinfo(参数));









有错请帮我纠正

不完善请帮我补齐。。。


谢谢

你用过SERVLET吗？

public class CateServlet extends HttpServlet{
   StringClass sc = new StringClass();

	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

		doPost(request, response);
	}


	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
	

		
		//得到表单数据
		String todo = request.getParameter("todo")==null?"":request.getParameter("todo");
		todo   =   new   String(todo.getBytes("ISO-8859-1"),   "GBK");
		String id = request.getParameter("selectid")==null?"":request.getParameter("selectid");
		id   =   new   String(id.getBytes("ISO-8859-1"),   "GBK");
	
		String newsid = request.getParameter("id")==null?"":request.getParameter("id");
		newsid   =   new   String(newsid.getBytes("ISO-8859-1"),   "GBK");
		String key = request.getParameter("key")==null?"": sc.Html2Text(request.getParameter("key")==null?"":request.getParameter("key"));
		key   =   new   String(key.getBytes("ISO-8859-1"),   "GBK");
		String otype = request.getParameter("otype")==null?"": sc.Html2Text(request.getParameter("otype")==null?"":request.getParameter("otype")); 
		otype   =   new   String(otype.getBytes("ISO-8859-1"),   "GBK");
		String catename = request.getParameter("CateName")==null?"": sc.Html2Text(request.getParameter("CateName"));
		catename   =   new   String(catename.getBytes("ISO-8859-1"),   "GBK");
		String cateName = request.getParameter("catename")==null?"": sc.Html2Text(request.getParameter("catename"));
		cateName   =   new   String(cateName.getBytes("ISO-8859-1"),   "GBK");
		String url = "";
		String info = "";
		boolean bool = false;
		List dataList = null;
		CateModel model = new CateModel();
		CateManagerImpl manager = new CateManagerImpl();
		NewsManagerImpl newsManager = new NewsManagerImpl();
	
       try{
    	
    	   if("add".equalsIgnoreCase(todo)){
    		   model.setCateName(catename);
    		   model.setCateNum(0);
    		   bool = manager.addCateInfo(model);
    		   if(bool==true){
    			   info="信息增加成功";
    			   url="/houtai/admin_cate.jsp";
    		   }else{
    			   info="信息增加失败";
    			   url = "/houtai/info.jsp";
    		   }
    		   request.setAttribute("info", info);
    	   }

    
    
       }catch(Exception e){
    	  e.printStackTrace();
       }
		
		//页面跳转
       request.getRequestDispatcher(url).forward(request, response);
		
	}
	
	

}

这是我的一个希望对你有用。

饿。。。。。。

很遗憾。。。。。

不过很感谢

我希望是

通过servlet的操作后 jsp能获取到方法文件对javabeen set后的值
