The evolution of more powerful processors for mobile devices (such as mobile phones, PDAs, etc.) has opened up new possibilities. These devices are small processing elements which can do a certain amount of work. They are becoming so powerful that they are able to run more complex software solutions such as web services. There exists a subdivision of these devices called cellular phones. Today's cellular phones are able to run web services. Web Services are Web APIs that can be accessed over a network and executed on a remote machine hosting the services. The frameworks that are now available (e.g. gSOAP 1, Nokia WS Framework 2 or Java ME3) for Web Service development come with a tool to generate C++ methods out of a WSDL [1] document at design time and have support for XML based communication at runtime. This approach of developing a Web Service means that the WSDL document must be known in advance to the programmer of the Web Service. This is actually a shortcoming for mobile devices, because it means that Web Services running on mobile devices can't be as portable and adaptable to change as they can be. By writing a library, which contains support for runtime WSDL and SOAP parsing, we try to make mobile phone applications more portable and adaptable to change. This paper illustrates an implementation of a solution that provides good support for developing web services for Symbian OS [2], which is an operating system designed for mobile devices. The second chapter of this thesis provides an introduction to web services on mobile phones, introducing the features and highlighting the bene ts. The third chapter provides an analysis of the web services library architecture (WESSYL). The fourth chapter illustrates an example of using library and the fth chapter provides the conclusion.
