Web Services are Required in every domain of the Industry, be it Java, Python or in any other Language. In this article, we will discuss How to Create Web Services In Java in the following order:

 

Introduction

A web service is a software that is made available on the internet and uses an XML messaging system. It is a collection of protocols and standards.

Creating Web Services in Java

These are the steps that need to be followed to create a simple web service in java.

STEP 1:

Install Apache Tomcat Server. After this, we need to add the server to the Eclipse IDE in the server tab. The tomcat version I’m using is Tomcat v8.5.

 

STEP 2:

Next, we create a dynamic web project.

Create a java file under /src folder. Give a name to the class.

STEP 4:

Inside HelloWorld.java file create a simple main method.

public class HelloWorld {
       public float addValue(float value) {
                                    return (value + 10);
                       }
       public float subtractValue(float value) {
                                    return (value - 10);
                        }
}

 

STEP 5:

We then need to create a web service. This is done by right-clicking on the Hello World.java file. We need to find Web Services and in that click on Create Web Service.

STEP 6:

The process takes some time to complete. Once completed, we can see TestWebSiteClient in the project explorer.

STEP 7:

Both projects are automatically deployed to the server. The Web Service test client window is automatically opened by Eclipse IDE.
