Using Eclipse to generate Java code and Deploy Web service

NBS supplies plug-in for Eclipse Generates Java code Can generate Web service code and deployment information Deploys to a development web server running inside the plug-in

Testing the Service

Web service test via SOAP Scope

Intro to Application Composer

Creates Rich User Interfaces Using AJAX and BPEL technologies Ability to execute web services and map to data fields Exists as a plug-in for Eclipse

Author / 04/21/23 / 9 Software AG

Creating the Application Composer Project

Project contains pages and bpel sequences Can import WSDL for services that your UI will execute

Author / 04/21/23 / 10 Software AG

Importing Web services

Import the WSDL generated by NBS Project can then invoke service during BPEL sequences WSDL is physically copied to project

Creating the Page Layout

Powerful new rich GUI interface Uses AJAX at runtime Page contains user interface controls Can be designed and tested directly in Eclipse Ability to use simple controls (textboxes, labels, tables) Also use complex controls (grids, trees, Google map) Pages are deployed to create BPEL sequence for the events and

methods
