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>本人的聊天器,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("<html>");
out.println("<head><title>MainServlet</title></head>");
out.println("<body bgcolor="#ffffff">");
out.println("<h3>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("</body>");
out.println("</html>");
out.flush();
out.close();
}
@Override
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doGet(request, response);
}
}
用的是weblogic服务器
从UserServlet跳转到MainServlet出现HTTP405错误，求高手指点.

MainServlet中又跳到了MessageServlet，MessageServlet是怎么写的？
全部servlet的配置又是怎么定义的，都贴出来看看。

题主,你用的是doGet和doPost方法,你加一个service方法,把逻辑写在service方法里面就O了

MessageServlet 没有doPost()？
