| The existing GUI tools for generating BPEL have no capability to analyze data types. Therefore, users need to manually verify whether two data types are matching.Then the process sequence of web services can be confirmed. Based on the architecture of web services specification, web services matching techniques can calculate matching score between two services. By using web services matching techniques, the efficiency of generating BPEL can be improved.Firstly a novel architectonic model of web services specification based on WSDL, named RCWSSM, is proposed in this paper. RCWSSM is used to describe web services specification extracting from WSDL and XML Schema. Secondly, based on RCWSSM, struct equivalence match algorithm and struct similarity match algorithm are designed. These algorithms are used to calculate web service composition informations. Lastly, based on the web service composited information, the regulation of transforming web service into BPEL is designed. According to the study and design described above, a GUI tool for generating BPEL based on web service matching, named RCGenBpel, is presented in this paper. Using the web service composition information, RCGenBpel can aid the generating BPEL process, and feasibility and effectiveness of RCGenBpel have been certified by the experiments. |
