#Netbeans rest web services full#
This article explores lightweight Restful services in Java through a full code example. The client makes requests in HTTP(S) and receives text responses in a format suitable for modern data interchange (e.g., JSON).Īlmost every general-purpose programming language has at least adequate (and often strong) support for HTTP/HTTPS, which means that web-service clients can be written in those languages. (The attendant downside is that it may be hard to determine what does not count as a Restful service.)įor a consumer or client, Restful web services are language- and platform-neutral. Restful is a style-indeed, a very flexible one-rather than a set of prescriptions about how services should be designed and structured. Restful web services can be as simple or complicated as needed. For example, the Restful API supports the standard CRUD (Create-Read-Update-Delete) operations through the HTTP verbs POST-GET-PUT-DELETE, respectively HTTP status codes inform a requester whether a request succeeded or why it failed.

Restful services treat HTTP as an API, thereby avoiding the complicated software layering that has come to characterize the SOAP-based approach to web services. Amazon, for example, has pioneered making the same information and functionality available through both websites and web services, either SOAP-based or Restful. An organization that has HTML-based websites can readily add web services for clients interested more in the data and underlying functionality than in the HTML presentation. Restful services build upon existing infrastructure and protocols, in particular, web servers and the HTTP/HTTPS protocols. Despite the alternatives to web services for distributed computing (e.g., web sockets, microservices, and new frameworks for remote-procedure calls), Restful web services remain attractive for several reasons: REST-style (hereafter, Restful) services now dominate in popular sites such as eBay, Facebook, and Twitter.
Services in the REST architectural style also made the scene about two decades ago, soon after the XML-RPC and SOAP trailblazers. For example, XML-RPC services appeared in the late 1990s, followed shortly by ones written in the SOAP offshoot. Web services, in one form or another, have been around for more than two decades.
