This document is one of three documents, which serves as a self learning program for developing a Web service with E2E Bridge®. The education leads you through a development process divided into three lessons, which will teach you to build services based on the E2E Bridge platform.
Welcome to lesson 3 of the E2E Education. By reading this document, you will learn
in the first iteration
how to draw more complex class diagrams
how to reuse activity diagrams
how to copy activity diagrams
how to use decisions
how to design a SOAP interface from scratch
how to work with arrays
how to use value pins
how to define iterations with an expansion region
how to use transformations
how to use static operations within action script
how to manage test cases
in the second iteration
how to read a file
how to use a backend adapter
how to use an alias
how to map XML data to objects
how to exchange messages with an external SOAP Service
how to use the E2E Action Wizard
The goal of this lesson is to model a Web service that receives a search request. The requested items are searched in an XML data source file. For each found record a currency conversion is performed. The necessary exchange rate is received from an external SOAP Service. If the search is successful, the Web service sends the search result back to the client.
Documentation Map
The BRIDGE is delivered with comprehensive documentation. Apart from this self-study, the BRIDGE also comes with many examples you can have a look at. Each feature is subject of an example that is ready to run.
This chapter provides an overview about all documentation available after installation. How to access the xUML examples is explained on Unzipping Examples. The complete documentation is available online.
