METHOD AND APPARATUS FOR PROVIDING A SERVICE IMPLEMENTATION

摘要

The invention provides a method for providing a web service comprising the steps of generating a XML (Extended Markup Language) based schema based on a service description of said web service, wherein the generated XML-based schema defines XML-based messages to be interpreted by the respective web service, generating a binary XML processor code for encoding and decoding said XML-based messages on the basis of the generated XML based schema, transforming said service description of said web service into a procedure skeleton code comprising one or several skeleton procedures each becoming an application procedure by implementing an application logic for the respective skeleton procedure, and generating a dispatcher code based on the service description, wherein said dispatcher code is adapted to interpret a byte stream produced by said binary XML processor code to invoke one of the implemented application procedures. Accordingly, the present invention presents an innovative approach to generate a source code for developing XML-based web services for small embedded devices with constraint resources. The generator enables the schemeless adoption and usage of standardized web service protocols in microcontrol based networks. This makes the development of applications of such networks much easier and also simplifies the integration of web service of other networks. The generated XML-based web service comprises a very low code footprint to be executed with microcontrollers.
