将注册信息提交到treatUser.java里面后要进行处理，其中包括姓名或密码为空，密码和确认密码不一致，注册成功。然后要在treatResult.jsp里面显示处理结果。要怎么做？
这是treatUser.java部分代码：
response.setContentType("text/html;charset=GBK");
ServletContext application = getServletContext();
String name=request.getParameter("name");
String passw=request.getParameter("passw");
String repassw=request.getParameter("repassw");
String sex=request.getParameter("sex");
String hobby=request.getParameter("hobby");
String intro=request.getParameter("introduction");
if((name!=null&&passw!=null)&&(passw.equals(repassw))){
application.setAttribute("userName",name);
application.setAttribute("userPassword",passw);
application.setAttribute("userPassword1",repassw);
application.setAttribute("sex",sex);
application.setAttribute("hobby",hobby);
application.setAttribute("introduction",intro);
}
String url = "/zhuceResult.jsp";
ServletContext sc = getServletContext();//sc即application
RequestDispatcher rd = sc.getRequestDispatcher(url);
rd.forward(request, response);
}
