Details
This course will teach you the essentials of Java Web Services. You’ll first explore the most widely adopted technologies for Java-based web services: SOAP and REST, as they allow standardized, scalable, and language-independent external application communication. You’ll also learn to work with the Jersey framework to build the REST APIs (application programming interface). Web services for Java applications based on the REST technology provide a normalized and scalable means to set up client communication with external applications. You’ll learn how to integrate RESTful applications with a relational database so that clients can interact with it and perform create, read, update, and delete (CRUD) operations on it.
Result
After completing this course, you are ready to built Java Web Services.
Prerequisites
You have programming experience and knowledge of the Java programming language.

Java Web Services: Getting Started with SOAP-based Web Services
- If you work on a team offering data or services to clients, you'll likely need to build web services. The most widely adopted technologies for Java-based web services are SOAP and REST, as they allow standardized, scalable, and language-independent external application communication.
- Use this course shows to learn how to build a web service that adopts the SOAP protocol. Use Maven to create a web service project and the JAX-WS library to build a web service class and a method that remote client applications can invoke. Then, deploy this service to a URL endpoint where clients can access it.
- Next, explore the automatically generated JAX-WS artifacts, including the WSDL file. Then, use the WSDL file to build a client application and interact with the server-side web service.
- Bu the end of this course, you'll be able to build SOAP-based web services using JAX-WS and Maven.
Java Web Services: Integrating Web Services with a Database
- SOAP-based web services for Java applications offer a standardized and scalable means to communicate with external applications. In this course, you'll build a SOAP-based web service app for a fictitious book store that will enable client apps to view, add, update, and delete books whose details are stored in a database.
- Begin by defining a Book class whose instances can be transmitted between applications using the SOAP protocol. Then, integrate a MySQL database with the web services app and load it with data that will be made accessible to client applications using CRUD techniques.
- Lastly, host your web service application in a production environment by deploying it to an Apache Tomcat web server.
- When you're done, you'll know how to use the SOAP protocol to enable client apps to interact with a remote database.
Java Web Services: Building REST APIs
- Web services for Java applications based on the REST architectural style allow you to communicate with external apps in a standardized and scalable manner independent of the programming language. This course demonstrates using the Jersey framework to build REST APIs in Java.
- Begin by implementing a simple method that returns data in response to a GET request. While doing so, explore the use of Jersey annotations to construct a URL to a particular web method and set it to respond to GET requests.
- As you advance, construct a response to incoming requests that includes HTTP status codes. Furthermore, examine the transmission of Java objects in the form of JSON structures as a response to an HTTP request.
- When you're done, you'll be able to use Java to build RESTful applications that can respond to HTTP GET requests.
Java Web Services: Enabling CRUD Operations with REST APIs
Web services for Java applications based on the REST technology
- provide a normalized and scalable means to set up client
- communication with external applications. This course demonstrates
- how to integrate RESTful applications with a relational database so
- that clients can interact with it and perform create, read, update,
- and delete (CRUD) operations on it. Learn how to link a MySQL
- database with a RESTful app. Set it up to respond to a GET request
- by looking up a table in your database. Advancing from read
- operations, establish add, update, and delete operations, defining
- methods that can respond to POST, PUT, and DELETE requests. By the
- end of the course, you'll be able to facilitate your clients to use
- your web service app to interact with a database.
Course options
We offer several optional training products to enhance your learning experience. If you are planning to use our training course in preperation for an official exam then whe highly recommend using these optional training products to ensure an optimal learning experience. Sometimes there is only a practice exam or/and practice lab available.
Optional practice exam (trial exam)
To supplement this training course you may add a special practice exam. This practice exam comprises a number of trial exams which are very similar to the real exam, both in terms of form and content. This is the ultimate way to test whether you are ready for the exam.
Optional practice lab
To supplement this training course you may add a special practice lab. You perform the tasks on real hardware and/or software applicable to your Lab. The labs are fully hosted in our cloud. The only thing you need to use our practice labs is a web browser. In the LiveLab environment you will find exercises which you can start immediately. The lab enviromentconsist of complete networks containing for example, clients, servers,etc. This is the ultimate way to gain extensive hands-on experience.
