userdelete.jsp

这是《JSP案例开发》的源代码,我找了好久才找到的,分享给大家

<%@ page
    language="java"
    contentType="text/html; charset=GBK"
    import="imis.*,javax.naming.*,javax.rmi.PortableRemoteObject,java.util.*"
%>
<%
  request.setCharacterEncoding("GBK");
  session=request.getSession();
  userStruct user=(userStruct)session.getAttribute("user");
  if(user==null){
  response.sendRedirect("../../login.html");
  }else if(!(user.userAccess.equals(new Integer(0))||user.userAccess.equals(new Integer(1)))){
     response.sendRedirect("../../error/user.html");
  }
else{
   try{
%>
<%
String userid=request.getParameter("userid");
userStruct us=new userStruct();
boolean ok=true;
try{
Context ctx = new InitialContext();
 //look up jndi name
     Object ref = ctx.lookup("UserController");
//cast to Home interface
     UserControllerHome userControllerHome = (UserControllerHome) PortableRemoteObject.narrow(ref, UserControllerHome.class);
     UserController userController = userControllerHome.create();
     userController.removeRecord(userid);}
     catch(Exception e){
     e.printStackTrace();
     ok=false;
     }
if(ok)
 response.sendRedirect("usercheck.jsp");
else
  response.sendRedirect("../../error/deleteerror.html");
%>
<%}
catch(Exception e){
    e.printStackTrace();
    response.sendRedirect("../../error/deleteerror.html");
}
