Programming Java SOAP and REST Web Services – JBoss / Eclipse Training
Pre-Requisites: Knowledge of Java programming is required. Experience with Eclipse is useful but not required. Understanding basic web architecture and the HTTP protocol, Web services, Java RMI, COM objects, etc. is helpful, but not required.
This course covers how to implement web services with JBoss using the most recent Java standards, JAX-WS for SOAP web services, and JAX-RS for REST web services. Since it is possible to use both web services styles, even within the same application, this course will show the student the strengths of both techniques and how to implement both types of web services properly. Testing web services is also more complicated than “normal” web applications, so this course covers the tools and techniques used to test web services in the labs.
This course “Programming Java SOAP and REST Web Services – JBoss / Eclipse Training” is designed to guide you to the concepts of advanced programming techniques. This training requires some coding experience in Java. We recommend you to undergo our module 1 – “Java 11” of our “Java Professional” training program to strengthen your foundation in core Java coding skills. In this course we will provide you with the knowledge to mastering advanced Java topics such as JDBC, Java SOAP, Hibernate Query Language(HQL), JSP’s Servlets, service-oriented architecture (SOA), JBoss / Eclipse, REST web services and Hibernate. This course will show the student the strengths of both web services styles within the same application and how to implement both types of web services properly. Testing web services is also more complicated than “normal” web applications, so this course covers tools and techniques used to test web services in the labs.
What is a Web Service?
Web Services work on a client-server model where client applications can access web services over the network. Web services provide endpoint URLs and expose methods that can be accessed over the network through client programs written in Java, shell script or any other different technologies. Web services are stateless and don’t maintain user session like web applications.
What are the different types of Web Services?
There are two types of web services:
SOAP Web Services: Runs on SOAP protocol and uses XML technology for sending data.
Restful Web Services: It’s an architectural style and runs on HTTP/HTTPS protocol almost all the time. REST is a stateless, client-server architecture where web services are resources and can be identified by their URIs. Client applications can use HTTP GET/POST methods to invoke Restful web services.
What is SOAP?
SOAP stands for Simple Object Access Protocol. SOAP is an XML based industry-standard protocol for designing and developing web services. Since it’s XML based, it’s platform and language independent. Our server can be found on JAVA and client can be on .NET, PHP etc. and vice versa.
What is REST Web Services?
REST is the acronym for REpresentational State Transfer. REST is an architectural style for developing applications that can be accessed over the network. REST architectural style was brought in light by Roy Fielding in his doctoral thesis in 2000.
REST is a stateless client-server architecture where web services are resources and can be identified by their URIs. 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. We can use XML, JSON, text or any other type of data for request and response.
Why should I become a Java Professional?
Here are a few reasons:
1) Java is one of the most widely used programming languages. There is no denying Java’s popularity using more than nine million developers on seven billion devices worldwide. Despite being released over 20 years ago, Java has been at the top of the TIOBE index, the measure of popularity within programming languages, for the last decade. Job prospects for people with Java skills are excellent with roles available across many different sectors.
2) There is more to Java developing than coding. When you become a Java developer, your work is varied due to the many different tasks that Java developers oversee. From designing interfaces to creating and testing dynamic applications, Java developers involved in every development process stage.
3) Java development is collaborative. An advantage of being involved throughout the development process is that Java developers collaborate with other professionals, such as Web Designers, Web Developers and Software Engineers. Collaboration develops communication and other transferable skills, which help advance your career as an IT professional.
4) Java is used in real-world applications. From healthcare to financial services, Java is used across many different business sectors and popular websites such as Facebook, Amazon and eBay. So, as Java developer, it is likely that your work will benefit not just the company you work for but also many ordinary people in real-life scenarios.
What role do Java developers play in IT development?
Java developers create complex web-based applications. Some examples include animated drop-down menus, images that change as a mouse moves over them, and sounds that play when clicked. Java is used extensively on e-commerce sites to collect data and validate user information. It is the job of Java developers to use this scripting language to modify the design and functionality of websites as requested by their clients. Java developers may write programs themselves or revise existing applications. They also identify opportunities to fine-tune and optimize applications of java developed projects. Java developers will often test programs to verify that they work correctly. This responsibility includes resolving technical issues through debugging, research and investigation. Java developers will also often mentor and provide technical guidance and instruction to lower-level IT staff, assisting with specific problems requiring a broad knowledge of subject matter processing.
Technology in the IT world is constantly changing, so knowledge becomes outdated in a few years. Therefore, a love of learning is essential for Java developers. Good researching skills are also crucial because there will always be new technologies to learn about. Java developers typically work on a team, so being a team player is extremely important. Good communication skills are also a must because Java developers must communicate effectively with their team and with clients.
