Java Unit Testing with JUnit 4.x from Terminal

JUnit

In this tutorial I will guide you through the process of installing and writing a simple java unit test all from the terminal (command line). I'm not going to go through explaining why test driven development is the way to go for most serious programmers out there, but rather explain how tests are created and then performed. Hopefully, when you go through this tutorial you will finally understand the advantages of unit testing yourself if not already so!

This tutorial assumes that you have a basic text-editor installed. In my demonstrations, I will be using the famous Vim text-editor; however, you can use your preferred text-editor let it be NotePad or any other text-editor you find suitable to your needs. Also, it is assumed that you have the Java Compiler and JVM installed.

Java Web Service Client with JAX-WS in Eclipse

In this tutorial, I will show how simple it is to create a web service client that consumes the web service created in the previous blog post. We will be using JAX-WS annotations to inject a reference to the web service in our web service client code. I will be using the Eclipse IDE (Indigo) to  build the web service client.

First let us start by creating a standard Java Project. I will name the project "SimpleCalculatorWebServiceClient". Click finish to allow Eclipse to create the Java Project.

Java EE Web Service with JAX-WS in Eclipse

In this simple tutorial I will demonstrate step-by-step how to build a java web service using Java API for XML Web Services JAX-WS in Eclipse. The JAX-WS API is available in Java SE 1.5 and later. JAX-WS can be used to build web services and web service clients that communicate using XML messages. For the purpose of this tutorial I will be using:

1. Eclipse IDE (Indigo) to create the web service.
2. Glassfish application server to host the web service.

Make sure Glassfish is installed and configured in your Eclipse IDE. For more information on how to configure Glassfish in Eclipse refer to this link.

First open Eclipse and create a "Dynamic Web Project". Name the project "SimpleCalculatorWebService". Set the Target Runtime to Glassfish, and the configuration to minimal.
