Java Webservices Soap Rest
SOAP is a standards-based Web services access protocol that has been around for a while and enjoys all of the benefits of long-term use. Originally developed by Microsoft, SOAP really isn’t as simple as the acronym would suggest.
REST is the newcomer to the block. It seeks to fix the problems with SOAP and provide a truly simple method of accessing Web services. However, sometimes SOAP is actually easier to use; sometimes REST has problems of its own. Both techniques have issues to consider when deciding which protocol to use.
SOAP is a more rigid set of messaging patterns than REST. The rules in SOAP are important because without these rules, you can’t achieve any level of standardization. REST as an architecture style does not require processing and is naturally more flexible. Both SOAP and REST rely on well-established rules that everyone has agreed to abide by in the interest of exchanging information.

Developing SOAP & REST Web-Services in JAVA
Prerequisites
- Strong Java programming skills are essential.
- Students must be able to read XML documents and to write well-formed XML by hand
- Knowledge of XML Schema will be helpful, too, but is not a strict prerequisite.
- Experience with other Java EE standards, especially servlets and JSP, will be very helpful in class, but is not strictly required.'
Learning Objectives
- Be able to describe the interoperable web services architecture, including the roles of SOAP and WSDL in component-based services and XML and HTTP in the REST architecture.
- Understand the importance of the WS-I Basic Profile for interoperable web services.
- Build JAX-WS services and clients that take full advantage of the automated data binding of JAXB.
- Build WSDL-to-Java and Java-to-WSDL services, with equal facility.
- Apply advanced techniques and best practices including proper exception handling, care around possible polymorphism, and use of context and lifecycle services.
- Use lower-level SOAP and XML APIs for services and/or clients.
- Customize data binding by specifying specific type mappings or altering method or parameter names.
- Incorporate binary data, such as images, into service and client code.
