webapp上传到局域网 其他计算机访问

学艺不精........其他计算机能够正常访问，各种操作也可以完成，但是提示信息出现在作为服务器的那一台计算机上，在服务器这边点确定了，其他计算机才能进行操作

给图呀。应该是你使用的是application（或ServletContext）存储的变量,把他换成session试试

是要代码的图么
HttpSession session=request.getSession(true);
request.setCharacterEncoding("utf-8");//防止中文乱码
response.setCharacterEncoding("utf-8");
response.setContentType("text/html");
carBean regBean = new carBean();//创建javaBean对象regBean
PreparedStatement sql;
session.setAttribute("regBean", regBean);
String inwhy = request.getParameter("why").trim();//获取网页传过来的值
String inone = request.getParameter("one").trim();
String inwho= request.getParameter("who").trim();
String indestination = request.getParameter("destination").trim();
String inonedate= request.getParameter("one_date").trim();
String inpeople= request.getParameter("people").trim();
String infzr = request.getParameter("fzr").trim();
String infgld= request.getParameter("fgld").trim();
String intwo = request.getParameter("two").trim();
String inopinion = request.getParameter("opinion").trim();
String indriver= request.getParameter("driver").trim();
String intwodate= request.getParameter("two_date").trim();
String inapplydate= request.getParameter("applydate").trim();
//String backNews="";
