What are Java web services and why are they important?
Web services are methods of communication between applications that use standard formats and protocols over a network. They allow different applications to share data and functionality regardless of their platforms, languages, or technologies. Web services are widely used in modern software development because they offer several advantages, such as:
They enable interoperability between heterogeneous systems.
They facilitate modularity, reusability, and scalability of software components.
They support loose coupling and high cohesion of software architecture.
They improve performance, reliability, and security of distributed applications.
They simplify integration, testing, maintenance, and evolution of software systems.
Java is one of the most popular languages for developing web services because it provides a rich set of APIs, tools, frameworks, libraries, and standards that support web service development. Java also offers portability, compatibility, performance, security, and robustness features that make it suitable for creating web services for various domains and scenarios.
SOAP vs REST web services
The two main types of web services are SOAP (Simple Object Access Protocol) and REST (REpresentational State Transfer). They differ in their architectural styles, message formats, communication protocols, design principles, advantages, and disadvantages. Here is a brief comparison of the two types of web services:
SOAP is a protocol for exchanging structured XML messages between applications.
REST is an architectural style for designing web services that use HTTP methods and URIs to manipulate resources.
SOAP supports multiple protocols, such as HTTP, SMTP, TCP, UDP, etc.
REST relies on HTTP as the underlying protocol.
SOAP messages are verbose and complex, requiring a lot of parsing and processing.
REST messages are simple and lightweight, requiring less overhead and bandwidth.
SOAP provides built-in security, error handling, and standardization features.
REST leverages the existing security, caching, and scalability features of HTTP.
SOAP is more suitable for enterprise-level applications that require high reliability, consistency, and transactional support.
REST is more suitable for web-based applications that require high performance, scalability, and flexibility.
JAX-WS and JAX-RS APIs
Java provides two main APIs for creating web services: JAX-WS (Java API for XML Web Services) and JAX-RS (Java API for RESTful Web Services). Both APIs are part of the Java EE platform and use annotations to simplify the development and deployment of web services. Here is a brief description of the two APIs:
JAX-WS is the Java API for creating SOAP-based web services. It supports both RPC-style and document-style web services. It also supports WS-* standards, such as WS-Security, WS-Addressing, WS-ReliableMessaging, etc. JAX-WS uses the WSDL (Web Services Description Language) to describe the web service interface and the SOAP protocol to exchange messages.
JAX-RS is the Java API for creating RESTful web services. It supports both client-side and server-side development. It also supports various media types, such as XML, JSON, plain text, etc. JAX-RS uses the HTTP methods (GET, POST, PUT, DELETE, etc.) to perform operations on resources identified by URIs. JAX-RS does not require a WSDL document to describe the web service interface.
What does the book cover and how can it help you?
Java Web Services Up and Running by Martin Kalin is a comprehensive guide that covers everything you need to know about web services in Java. The book is divided into 12 chapters that cover the following topics:
Getting started with web services in Java
This chapter introduces the concept and history of web services, explains the differences between SOAP and REST web services, and gives an overview of the JAX-WS and JAX-RS APIs. It also shows how to set up the environment and tools for developing web services in Java, such as Eclipse IDE, Tomcat server, SoapUI tool, etc.
Creating and consuming SOAP web services
This chapter shows how to create a simple SOAP web service using JAX-WS annotations and how to generate a WSDL document from it. It also shows how to create a client application that consumes the web service using various approaches, such as dynamic proxy, dispatch API, service endpoint interface (SEI), etc. It also explains how to handle exceptions and faults in SOAP web services.
Creating and consuming RESTful web services
This chapter shows how to create a simple RESTful web service using JAX-RS annotations and how to map Java objects to XML or JSON representations using JAXB or Jackson libraries. It also shows how to create a client application that consumes the web service using various approaches, such as HttpURLConnection class, Jersey client API, Apache HttpClient library, etc. It also explains how to handle errors and status codes in RESTful web services.
Advanced topics and best practices
This chapter covers some advanced topics and best practices for developing web services in Java, such as:
How to use HTTPS for secure communication between web service provider and consumer.
How to use WS-Security standard for message-level security in SOAP web services.
How to use OAuth 2.0 protocol for authorization in RESTful web services.
How to use JUnit framework for testing web services.
How to use Swagger tool for documenting web services.
How to use Apache CXF framework for developing web services with advanced features.
