I have a vps set up to running a MySQL database already by zpanel but when I try to connect to the database with Java I am unable to connect and receive the message:
com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure
The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server."
I have MySQL Connector(dev.mysql.com/downloads/connector/j) already added to my build and tried it with both the url and the ip. This is my connection code:
package net;
import java.sql.*;
import javax.swing.JOptionPane;
public class LoginDatabaseConnection {
Connection conn = null;
[Code] ....
The code is from youtube but when I connect to localhost it works fine however when I try to connect to the VPS the above error happens.
i want o know that how can i connect my sql database to java

I am creating a JSP page with a html table to display employee directory. This is scriptlet :
<%
List<Employee> list = new ArrayList<Employee>();
PhoneListController controller = new PhoneListController();
list = controller.getAllContacts();
for (Employee eachEmp : list) {
%>
and then i display the table rows and columns for each employee object(PS: I know scriptlets are bad and obsolete but this is my first individual project.)
I would like to change the background color of certain rows based on value of one particular value(based on eachEmp.getManagerCode).
How can i achieve that by using javascript? I tried to call a js function by calling onload event on . But as I need to check for each row that is not the possible solution. I have not tried jquery yet as I am very new to jquery and I didnt quite understand how to do it in jquery.

I get this error when I load a HTML page with WebEngine. The HTML is getting generated by an own (Java-)ServerSocket. How can I figure out where the problem is? I can load the HTML file successfully when loading the(same) generated HTML file from the local filesystem. Maybe the http headers causing these problems ? On the other hand I can load the page without problems in Firefox. How to get more information ?
View Replies View RelatedI would like to make a database using HTML and Java. I already made something like this using swing. I am just looking for some pointers here. I just started looking into Java Play 2 and I have a feeling this is what I am looking for. JavaEE is very complicated and I have read that it is being phased out. What is your opinion on this?
I want to make a static HTML page and put it on my home network and treat one of my computers as the sever accessing mySQL.

I want to extract a specific String from HTML, specifically, I want to extract a String from in between <...>
So far, I've got this
package main;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.URL;
import java.net.URLConnection;
public class HTMLGrabber {
static String allOneString = "";

The problem I have is when I change the last parameter in this line:
System.out.println("And the Keywords are:
" +allOneString.substring(allOneString.lastIndexOf("meta name="keywords" content=") + 30, allOneString.indexOf("Fictional History">")+17));
to
System.out.println("And the Keywords are:
" +allOneString.substring(allOneString.lastIndexOf("meta name="keywords" content=") + 30, allOneString.indexOf("">")));
i.e. the generic alternative, I get this error message:
Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String index out of range: -366
at java.lang.String.substring(Unknown Source)
at main.HTMLGrabber.main(HTMLGrabber.java:45)
Is there a better and simple way to extract a substring?

View Replies View RelatedI have a assignment in which the code has to scrape a web page for a little bit of data including the link to the next page, follow the link, and do this 100 times. It is scraping all the data correctly, including the link, but it isn't following the link to scrape the data on that next page. Instead, it is displaying the first page's data 100 times. I have the code in a while loop where it reads in one character at a time from the page into a string and then uses pattern matching to get the data and the next link from the string. Then it correctly displays the data and should loop back to connect to that next link and read one character at a time into the string and so on.
I have printed the link to the console and it is good. I don't get any errors. I just can't figure out where exactly the problem is. Here is my code:
import java.awt.*;
import java.io.*;
import java.net.*;
import java.util.regex.*;
