这是UserServlet
public class UserServlet extends HttpServlet{
@Override
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html;charset=GBK");
request.setCharacterEncoding("GBK");
PrintWriter out = response.getWriter();
out.println("<html>");
out.println("<head><title>UserServlet</title></head>");
out.println("<body bgcolor=\"#ffffff\">");
out.println("<h3>我的聊天器,进入聊天系统...");
ServletContext context = getServletContext();
//判断用户列表存在
if(context.getAttribute("userlist")==null){
Vector aduser = new Vector();
context.setAttribute("userlist",aduser);
}
//判断信息列表存在
if(context.getAttribute("messagelist")==null){
Vector message = new Vector();
context.setAttribute("messagelist",message);
}
out.println("<form method='post' action='/SessionTrackingDemo/servlet/MainServlet'>");
out.println("昵称<input type='text' name='uname'/>");
out.println("<input type=submit value='登录'/>");
out.println("</form>");
out.println("</body>");
out.println("</html>");
out.flush();
out.close();
}
@Override
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doGet(request, response);
}
}
这是MainServlet
public class MainServlet extends HttpServlet {
private static final String CONTEXT_TYPE = "text/html;charset=GBK";
//添加用户请求分派
@Override
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType(CONTEXT_TYPE);
request.setCharacterEncoding("GBK");
PrintWriter out = response.getWriter();
out.println("");
out.println("
out.println("");
out.println("
进入聊天系统...");
ServletContext context = getServletContext();
Vector vc = (Vector)context.getAttribute("userlist");
String username = request.getParameter("uname");
vc.add(username);
RequestDispatcher view = request.getRequestDispatcher("/servlet/MessageServlet?uname="+username);
view.forward(request, response);
out.println("");
out.println("");
out.flush();
out.close();
}
@Override
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doGet(request, response);
}
}
从UserServlet跳转到MainServlet时出现HTTP４０５错误，求高手指点迷津
用的是weblogic服务器
