As I promised in my article Developing a simple e-commerce application from scratch to production using SpringBoot , I am starting first post by introducing the application JCart that we are going to build. One of my friend makes quilling toys and she sell them by advertising on Facebook or through word of mouth. Now she is getting more and more customers and she wants to expand her business by going online.

We can find plenty of information on any technical topic, be it Java, .NET, Python or any frameworks like Spring, Hibernate, CDI, JSF etc. You can find hundreds of well written blogs on many of these topics. For example, you can find lot of tutorials on how to use SpringBoot or how to use various mappings in JPA/Hibernate or how to do form validations in JSF etc. Also, there are plenty of books published by well established publishers on most of the technologies.

As I mentioned in my previous post Thinking of moving from Windows to Linux? I am moving from Windows to Linux. Setting up my development environment is a bit tedious because I have to hunt down the applications and execute various commands to setup. So I thought of make a note of them in a post so that it will be easier for me next time. I am using Ubuntu/LinuxMint system so I am using apt-get to install, if you are using Fedora/CentOS you can use yum/dnf.

While learning some of the Linux commands we may want to use SSH commands to login into a remote Linux system and we may not have a dedicated Linux system to play with. In this post I will explain how I am using my Linux OS installed on VirtualBox to SSH from Windows OS. 1. Install openssh-server on Linux OS in VirtualBox sudo apt-get install openssh-server On some Linux distros (ex: Fedora) the openssh server won’t start automatically.

I have been using Windows operating system from the beginning. When I first started using computer Windows XP was the latest operating system and it was amazing. After few years I started my career as a Java developer and in my office also I have been using Windows only. After few years Windows Vista got released and I suffered with it for few months and then Microsoft released Windows 7 which is the best Windows operating system IMO.

I am Siva, working as a Software Developer in Hyderabad, India. Working as a Software Developer is very exciting as you see new things coming in everyday. If there are no new things at least we put a new fancy name to some old concept and celebrate (#microservices) :-). But in my opinion working as a Software Developer in India is little bit different and hard too. Few things are good, and few things are bad.

In Java community Spring vs JavaEE is a never ending debate. In such debates people form two groups consisting of evangelists, architects and hard core fans of one platform and debate endlessly. Those who participate in the debates may be architects who are responsible for platform selection. But what would developers think about this Spring vs JavaEE debate? I am a Java developer who uses both Spring and JavaEE and I am not part of Spring or JavaEE fan club.

I wanted to explore CentOS 7 Linux, so I installed it on my Oracle VirtualBox. Installation went smoothly ,but I had a hard time to install Virtualbox Guest Additions to get full screen. I thought of sharing the steps I performed so that it may be helpful for others. After installing CentOS 7, before installing Virtualbox Guest Additions first thing we need to do is update system. sudo yum update

Like many people I started working with computers on Windows XP operating system. Even after starting my career as a Java developer I have been working on Windows for all my development activities. Initially I didn’t get a chance(need) to work on Unix/Linux because we didn’t have access to any of production systems which are using Linux. After few years we got a new client for whom we need to do deployment also in QA/UAT environments which are all Linux based.

IT is one field where you can find new things coming everyday. Theses days the whole developer community websites are flooded with MicroServices and Docker related stuff. Among them the idea of MicroServices is very exciting and encourages better way of building software systems. But as with any architectural style there will be pros and cons to every approach. Before discussing what are good and bad sides of MicroServices approach, first let me say what I understood about MicroServices.
