In this tutorial, I will help you get started with RESTful web services in Java by developing a Java web application running on Apache Tomcat server – this web application hosts Restful web services powered by Jersey – an open source framework for developing RESTful web services in Java.
What are the advantages and disadvantages of RESTful Web Services?
REST is an architectural style not a protocol. Advantages of RESTful Web Services. Fast: RESTful Web Services are fast because there is no strict specification like SOAP. It consumes less bandwidth and resource. Language and Platform independent: RESTful web services can be written in any programming language and executed in any platform.
What is the difference between REST API and JAX-RS API?
REST web services request and response types can be XML, JSON, text etc. whereas SOAP works with XML only. JAX-RS is the Java API for REST web services whereas JAX-WS is the Java API for SOAP web services. There are two major implementations of JAX-RS API.
What is the difference between rest and SOAP Web Services?
REST Client applications can use HTTP GET/POST methods to invoke Restful web services. REST doesn’t specify any specific protocol to use, but in almost all cases it’s used over HTTP/HTTPS. When compared to SOAP web services, these are lightweight and doesn’t follow any standard.
What software do I need to run the RESTful service?
In order to follow this tutorial the following software is needed: 1) Eclipse. Download Eclipse Java EE IDE for Web Developers, I used Luna. 2) The Jersey framework. I used version 2.18. 3) Tomcat. The Restful service will run on a Tomcat server. I used Tomcat 8 64 bit for windows.
What is the Jersey framework for REST API?
This document contains a simple tutorial on how to build REST services using the Jersey framework. This framework is the reference implementation for the 2007 Java Specification Request (JSR) 311. This standard (also known as JAX-RS [Java API for RESTFul Services]) specifies a Java API for REST.
