Mobile devices use wireless networks that have limited range. Therefore, they may not always be connected to a network. This kind of intermittent connectivity in mobile devices has been one of the factors inhibiting enterprise-level adoption of pervasive mobile applications. Occasionally Connected Computing (OCC) deals with this problem. The challenge that mobile application developers face today is to develop applications that will let users interact uniformly with the application regardless of the connection status.

However, leveraging Web Services for occasionally connected mobility applications falls flat because of a lack of reliability. In t... (more)

WSDL 2.0: A Pragmatic Analysis and an Interoperation Framework

Web Service Description Language (WSDL) represents an IDL describing the contract between the service requestor and the service provider in much the same way that a Java interface represents a contract between client code and an actual Java object. The crucial difference is that WSDL is platform- and language-independent and used primarily (although not exclusively) to describe SOAP serv... (more)
