    The chance of them knowing Chelsea football club back then was very unlikely.

    I'd say it's more of an area in London, and not the football club. After all, they call it soccer!

Getting height and width of image in Java

Yesterday I was working on something that requires manipulation of image for getting its properties. After searching over the internet I found a very intersting class on Java i.e ImageIO and BufferedImage class. These classes are good enough to manipulate images. there are many other claases also. But what I need i got it from these. I found many developers searching over internet for getting properties of image and there is no good small example for that. Thats why I thought why not creating a simple code to manipulate the image and help the developers. Here is the small code that helps to get the height and width of the image. Enjoy it!! import java.awt.image.BufferedImage; import java.io.File; import java.io.IOException; import javax.imageio.ImageIO; public class GetImage { public static void main(String[] args) { try { File f = new File("E:/Vinod/Docs/Pics/krishna_01.jpg"); BufferedImage image = ImageIO.read(f); int height = image.getHeight(); in...

We need the following things to work: CA certificates including, private key and certificate. In this article, we are using the GoDaddy wild card certificate. Spring Boot application OpenSSL library Convert the certificate and private key to PKCS 12 First of all, we need to convert the CA certificate to .p12 format . We need to have OpenSSL on the system to work with command. Also, we need to have all files in the same directory where we are running this command.

First Time Deployment of war file to IBM Cloud

In this post, I will put a very basic deployment of Java war file on the IBM Cloud . Previously, IBM Cloud was known as IBM Bluemix . But in this post, I will prefer using the IBM Cloud and not the bluemix. I was facing problem while deploying the war file on the IBM Cloud for the first time. I am not a DevOps person who knows about the servers as well. But my job was to deploy the application on the IBM Cloud I need to do it. So, I tried googling around but have no idea about how to do it. There are some examples are given but they are not so basic to be understood by a developer who wants to deploy the application in Cloud. But I manage to do it. And I will explain all the steps that are needed to deploy the application to the Cloud. The application I am going to deploy is the Spring Boot application. Requirements 1. IBM Cloud account. 2. IBM Bluemix CLI 3. war file (spring-boot application) IBM Cloud  Setup After signing for IBM Cloud, go to the IBM Cloud Dashboard...
