Choosing the most suitable technologies and architecture has a high importance.

Efficiency of communication, data sharing and remote procedure calls is a crucial part

of the system from scalability and maintainablity viewpoints. Many solutions were

created for cooperation of components and invoking services in other components, but

the number of users often increases to the order of millions, and new tools and solutions

have to be independent of technology and programming language.

REST (Representational State Transfer) is an architectural style gaining

in popularity that was introduced and defined at the time when the HTTP protocol was

specified. The technique uses several well-defined architectural constraints for

designing distributed systems. It focuses on the interaction and roles of components and

ignores their inner structure. Applications conforming to the REST constraints are

called “RESTful”.

RESTful web applications can be developed in a technology-independent

way, using any programming language that supports HTTP protocol-based development

and RESTful principles. Such framework was created by Spring and its components,

providing a platform for the development of enterprise applications using web GUIs,

security, backend functionalities and many other facets of a web application

development can be implemented easily using Java.

The aim of this thesis is to reveal the possibilities of RESTful principles,

Java and Spring through the process of application development.
