Hi,
I’m new to jsp and dhtmlx grid.
When I try the way that mention in this site (docs.dhtmlx.com/doku.php?id=dhtm … _rendering), I can successful to load all the data from database to the grid in my jsp page.
So, I want to try to update the data from the grid table to database, I try to use the connector.js. Unfortunately, it cannot work. Here is my code and the error.
contactMgt.jsp
<%@ page language=“java” contentType=“text/html; charset=ISO-8859-1” pageEncoding=“ISO-8859-1”%>
loadcmData
<jsp:useBean id=“db” scope=“request” class=“db.dbconnection” />
<%@ page import=“java.sql."%>
<%@ page import="java.io.”%>
<%@ page import=“com.dhtmlx.connector.*”%>
<%
Connection conn = db.connect();
GridConnector c = new GridConnector(conn);
c.render_table(“TESTING”,“ID”,“ID,NAME,DESCRIPTION”);
%>
Here is the error messages:
java.lang.NullPointerException
at com.dhtmlx.connector.BaseConnector.parse_request(BaseConnector.java:351)

I did included all the required files and classes. I hope that anyone can help me, so that I can proceed for further learning. Thank you so much.
