The introduction of XML was hailed as the foundation of the latest technology that will allow interoperable businesses. Over several years, the XML standards have evolved and it has been incorporated in every facet of innovative development. All the operating systems, programming languages, application servers, web servers, networking protocols and data basis are being operated with XML.
The search of a standard way for two pieces of software to communicate with each other, led to the starting of XML in 1998. It was then incorporated into various networking protocols. SOAP which is the Simple Object Access Protocol and XML-RPC are the specifications that introduced the distributed-computing environment that provided a platform independent way for the software to communicate. SOAP was supported by each and every company as it had the potential for interoperability at a level that was not possible before.
After the success of SOAP, many other web developments came into existence. Web Services Description Language (WSDL), Universal Discovery Description, Integration (UDDI) specifications were introduced. Some more applications such as ebXML, OASIS technical communities along with a variety of SOAP extensions came on the front as well. But the industry unified around SOAP, WSDL and UDDI because they were the core technologies that were required to achieve software interoperability for the future.
Although the web services are language and platform independent, web developers are required to create programs in programming languages. It was not long when technology used J2EE platform for integrating the web services. Java programs were created to build, locate and consume web services. Now many technologies have been introduced in order to shorten the gap between Java and web services. J2EE plays an important role in the enterprise; it defines the behaviors of core capabilities that every software program requires.
Web services are now the latest approach for advertising enterprise services that are hosted on a platform. The enterprise requirements by these platforms are such as security, pooling, transactions and batch processing. Web services expose the services that provide these infrastructure capabilities. They also provide a standard method to discover the services that are installed onto a platform.
Java Web Development is a format that is designed to integrate non-Java developers with J2EE. Developers create web services and a single Java class represents web service implementation. That Java class then has simple and predefined JavaDoc tags that are inserted into the Java class, a code generator then creates important J2EE components that are required to implement web services.
Tool kits that are based on older versions of SAML have already been released by most of the single-sign-on vendors in this field. Once the specification is completed, the upgrade is available for free. Netegrity marketed the release of JSAML Toolkit in order to build Java-based applications that use SAML. This allowed the Java-based web services to incorporate single-sign-on solution that work with other SAML-based security environments.
The major differences between previous and the new breed of technology is the standardization of the web services. This new type of technology is based on standardized XML and is supported globally by major technology firms.
