我有做的一个简单网站只有JSP。我想知道怎么部属WEB.xml文件？ 服务器是TOMCAT

Question

web.xml不是需要部署么？
我还有其它的jsp文件，怎么写进web.xml中？什么格式？或者上面的web.xml文件不需要修改？

Answer 1

你的问题跟web.xml无关，查错吧

Answer 2

         
有一段这样的代码：
  <%
                String user=request.getParameter("Name");
                String code=request.getParameter("Password");
                String purview="", str="";
                Connection conn;
                Statement st;
                ResultSet rs;
                try{
                    Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
                    conn=DriverManager.getConnection("jdbc:odbc:DatebaseDesign","sa","sa");
                    st=conn.createStatement();
                    str="select * from Users where Names=\'"+user+"\' and Passwords=\'"+code+"\'";
                    rs=st.executeQuery(str);
                    if(rs.next()){
                        purview=rs.getString("Purview");
                        System.out.println(purview);
                        conn.close();
                        if(purview.equals("admin     ")){
                            response.sendRedirect("admin.jsp");
                            return;
                        }else{
                            response.sendRedirect("user.jsp");
                            return;
                        }
                    }else{
                        response.sendRedirect("error.html");
                        return;
                    }
                    
                }catch(SQLException s){
                     s.printStackTrace();
                    //System.out.println(str);
                    out.print("<center><h3><操作失败,发生了错误!></h3></center>");
                }catch(ClassNotFoundException c){
                 c.printStackTrace();
                    //System.out.println("驱动程序出问题了");
                    out.print("<center><h3><<操作失败,发生了错误!>></h3></center>");
                }
            %>我用netbeans时没有问题。把NB里抽文件放到TOMCAT里时就出问题了。
