Web Services

Definition

Web Service is a software system that allows the interoperability among machines on the same network. 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 Services.VulCon^® helps the user to pubblish an ESB service as 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 more efficient pull-based 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 starting from an GreenVulcano^® ESB service and creating the WSDL and the AAR to deploy (bottom-up development method), the second one, starting from a WSDL, creating GreenVulcano^® ESB services for each operation chosen (top-down development method).
