yes it is possible to edit in same page.

You can use ajax for it. form of project insert in jsp using jstl

<%@ page import="java.io.*,java.util.*,java.sql.*"%>
<%@ page import="javax.servlet.http.*,javax.servlet.*" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/sql" prefix="sql"%>
<c:if test="${empty sessionScope['loginUser']}">
    <c:redirect url="login.jsp" />
</c:if>
<jsp:include page="header.jsp" />

                <!-- Basic inputs -->
                            <!-- Basic inputs -->
 <script src="http://code.jquery.com/jquery-1.10.1.min.js" ></script>
<script>
$(document).ready(function(){
    $("form").on('submit',function(event){
    event.preventDefault();

             var p_title = document.getElementById('p_title').value;                      
             var p_decription = document.getElementById('p_decription').value;
             var s_date = document.getElementById('s_date').value;                        
             var e_date = document.getElementById('e_date').value;
             var p_language = document.getElementById('p_language').value;

        $.ajax({
                    type: "POST",
                    url: "insert_project.jsp",
                    data: {p_title:p_title,p_decription:p_decription,s_date:s_date,e_date:e_date,p_language:p_language},
                }).done(function(data){
                    alert("Data Inserted succesfullly");

                });

    });

});
</script>

                          <jsp:include page="sidebar.jsp" />

insert_project.jsp

<%@ page import="java.io.*,java.util.*,java.sql.*"%>
<%@ page import="javax.servlet.http.*,javax.servlet.*" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/sql" prefix="sql"%>
<%@include file="connection.jsp"%>



<sql:update dataSource="${snapshot}" var="result">
            INSERT INTO project_master(project_title,project_description,project_start_date,project_end_date,project_language) VALUES (?,?,?,?,?);
            <sql:param value="${param.p_title}" />
            <sql:param value="${param.p_decription}" />
             <sql:param value="${param.s_date}" />
              <sql:param value="${param.e_date}" />
             <sql:param value="${param.p_language}" />
</sql:update>

this is how you can use ajax in jsp. this is demo of insert you can pass is for update and delete in ajax and make page for it write code for update and delete.
