Definition

Web Service is a software system that allows the interoperability among different machines. Through a Web Service it is possible to pubblish business services using a contract, called WSDL.

GreenVulcano® ESB provides a very simple method that helps developers to manage Web Services operations as:

  • create
  • invoke
  • deploy
  • publishing
  • undeploy

Any service flow can be pubblished in GreenVulcano® ESB as a Web Service.VulCon® helps the user to create or invoke a web service, leaving the user the only task to define the data structures in order to interact with the external world.

GreenVulcano® ESB provides a complete management of Web Services through Axis2 platform. It supports:

  • Web Services stateful and asynchronous
  • Processing SOAP Messages with XML parsing using the more efficient AXIOM pull-parser instead of DOM (Document Object Model)
  • Increased Scalability
  • Hot deploy and undeploy

Create new Web Services with VulCon

VulCon provides two wizards to create new Web Services. The first one starts from a GreenVulcano® ESB service and creates the WSDL and the AAR to deploy (bottom-up development method), the second one, starts from a WSDL and creates GreenVulcano® ESB services for each chosen operation(top-down development method). If you want to invoke a Web Service operation, instead, you can choose Wizard Call Web Service or if you want to simply redirect a Web Service call to a different endpoint you can choose Wizard Proxy Web Service

The section Web Service in GvConsole contains three main pages:

  1. 'General parameter', shows the general configuration of business web services and the UDDI Registry's configuration,
  2. WSDL, allows to generate or delete WSDL files, and to deploy the Web Service
  3. UDDI, allows to publish Web Service in UDDI registry, if the UDDI registry has bean configured.
