This Project contains 2 Java routines for transferring a model expressed in the Unified Modeling Language (UML) tool, Rhapsody, into the analysis tool, OPNET. This incorporates OMG's SPT (Schedulability, Performance and Time) Profile to specify the timing parameters. One Java routine (XmlTransformer) takes the output of the UML tool in the form of XML Metadata Interchange (XMI 2.1), translates it into S-PMIF (Software Performance Model Interchange Format) and the second Java routine (spmif2opnet) translates the S-PMIF into XML that can be read by OPNET. The final OPNET model utilizes the Detailed server model built into OPNET (14.5) to simulate the software performance.
