Introduction
GreenVulcano® ESB connects applications and heterogeneous technologies, providing services of orchestration in a consistent way , security, messaging, intelligent routing and data transformation, acting as a backbone through which software services and application components traveling. The key figures that come into play in the configuration of an ESB are the Business Analyst, the person who creates the flow and the Technical Specialist, the person who implements the flow drawn from the Business Analyst. VulCon is designed as a plug-in for Eclipse.
Requirements
The following are the requiriments for the VulCon plugin installation:
JDK 1.6 or higher
Eclipse 3.5 or higher
Installation
The installation procedure consists in decompressing the vulcon-(Version Number).zip file and then copying the jar file in the Eclipse dropins folder. After starting eclipse, you can check if the plugin has been installed correctly, following the menu item Help > About Eclipse Platform > Installation Details If present, the installation of the plugin has been successful. The VulCon License View shows your VulCon plugin License, the features enabled and the validity. Exploren menu of Eclipse Windows > Preferences > VulCon > VulCon License
Create New Project
VulCon has its own type of project, in which files are created for the initial operation of the views of the new project in more than one switch to the perspective VulCon where there are three views for configuration. The three views for configuring VulCon are:
| Core: | Represents the core configuration file of GreenVulcano® ESB. |
|---|---|
| Adapters: | Represents the configuration file of the adapters of GreenVulcano® ESB.The adapters view may change depending on the installation or the license of VulCon that you use. |
| Variables: | Represents the file where you define the variables identified in previous views. |
Example Creating a new VulCon project
First flow service
The easiest way to create a VulCon Service is interacting with the “Wizard New Service” option. From the Core view, select the wizard item in the drop down menu shown expanding the GVServices element and clicking on the Services element with the right mouse button. In addition to service name, user may select a group (among those ones already configured) and a communication paradigm between the couples Client-ESB and ESB-Server. In this new service, client will be any system suggested with GreenVulcano® ESB name, and server will be an internal GreenVulcano® ESB test service.
VulCon Context Menus and Tooltips
Elements of VulCon views are described by an associated DTD. Each element has both formal and improved controls defined in the same DTD. Context menu and popups works through this mechanism, and they appear clicking on a VulCon views element with mouse right button (Fig.1)
In addition, comments and warnings (reported in red colour background) of DTD elements appears as tooltip when user hovers the cursor over an item. (Fig.2)
Web Services
One of the most commonly used technologies are Web Services, that are the exposure of business services to the external world, using a contract called WSDL. VulCon helps the user to expose an ESB service as a web service, leaving the user the task to define data structures in order to interact with the external world. VulCon provides two wizards to create new Web Services. The first one starting from an ESB service and creating the WSDL and the AAR to deploy (bottom-up development method), the second one, starting from a WSDL, creating ESB services for each operation chosen (top-down development method).
