Modeling and Generating Mobile Business Processes Lasse Pajunen Nokia Research Center Nokia Corporation Anna Ruokonen Institute of Software Systems Tampere University of Technology ICWS 2007

Introduction 2 We propose rules to guide modeling of mobile business processes � Import existing WSDL decriptions into UML models � Generate executable BPEL descriptions With appropriate WSDL definitions Introduce our implementation of the approach

Introduction 3 Short message services (SMS) are developing very rapidly Modern mobile devices can have support for Web services Some mobile devices have proper Web browsers

Introduction 4 A process definition is a representation of a business process in a form which supports automated manipulation Discovering and communication of Web services is based on WSDL descriptions

Introduction 5 Several languages have been developed for service coordination and orchestration � BPEL � XPDL We propose UML 2 -based rules for designing mobile processes with mapping to executable BPEL descriptions Model-driven development (MDD) � extension to an existing IBM’s UML 2 CASEtool

Introduction 6 The first step is to locate existing WSDLs and to translate them into UML model Based on operations defined in the imported WSDLs, a selection of process actions are generated Finally, the mobile process model is translated into executable BPEL code

Introduction 7

Model-based mobile process development 8 Import existing WSDL descriptions Create template for the mobile process model Define the mobile process model Export WSDL descriptions Export BPEL decription.

Group messaging process 9

Group messaging process 10 Starting from WSDLs � The process development is started by specifying the locations of the existing WSDLs and importing them into the process model as UML class model representation � Stereotyped as wsdl Starting from an empty model � Yhe user can create automatically an exemplification template of the process model
