About XML Web Service and its purpose

XML web services are the fundamental building blocks to distributed computing on the web. XML Web services are built using XML, SOAP, WSDL, and UDDI specifications. They comprise of a set of base line specifications that provide the foundation for application integration. Web Services are applications that share or exchange data, and automate processes over Internet.

There are many applications based on Bio-Informatics such as BLAST, ClustalW, and GeneScan that uses Webservice are available in a wide spread. To deploy a web service the following steps have to be followed:

• Open a document structure to contain Input and Output documents.
• Create a WSDL.
• Write a Wrapper Class around an Executable program.
• Deploy the Wrapper class.

The Web Services Resource Framework proposes a model for Web Services. The Web Services Resource Properties Specification provides a means by which the requestors can view and Edit the type and resources of Web Service Resources state through Web Service Interface.
It also defines a set of message exchanges that allows the requestor to update the property resource of the instance.

XML is also used to send SMS messages. Short Message Services (SMS) is a term that is used for sending messages through Mobile Phones.SMS is similar to sending E-Mails. Since, the transactions that are carried out through HTTP result in interoperability problems; the SMS forums have developed 2 applications:

• Short Message Application Part (SMAP) : It is an XML format for the messages themselves.
• Mobile Message Access Protocol (MMAP): It is a SOAP-based protocol for sending those messages.

SMAP Messages:

The actual message passed is expressed as SMAP message. The SMAP protocol was developed based on the fact that when compared to the Binary form that the SMS take currently,
The XML based format is more convenient to use and is interoperable.

It is more convenient to use a MMAP when it is used with the SOAP structure.

It possible to create Web Services in a network by combining the features of JAVA and XML.
The JAVA technology Web Services Model is based on open standards that allow developers to create solutions from compatible products. It allows developers to create innovative solutions to diverse problems without being locked on. The JAVA technologies for XML offer developers, powerful tool set for developing and deploying JAVA based applications of the JAVA platforms portable code and XML’s Data.

The JAVA platform and XML are two open industry standards that lower the cost of information and sharing Data.
