Web Services
Definition
Web Service is a method of communication between different machines. Using a Web Service it is possible to publish 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 published 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:
- Stateful and asynchronous Web Services
- 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 for creating 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), while the second one starts from a WSDL and creates GreenVulcano® ESB services for each chosen operation (top-down development method). If you need 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.
You can publish a GreenVulcano® ESB service as a generic Web Service with the following operations:
- requestReply
- requestReplyResponse
- request
- requestResponse
- getReply
- getReplyResponse
- getRequest
- getRequestResponse
- sendReply
- sendReplyResponse
- execute
You can get the WSDL for the service at location:
http://<host>:<port>/gvaxis2/services/GreenVulcanoWebservice?wsdl
you can choose Wizard Enable GreenVulcano Web Service
GV Console Web service section
The Web Service section in GV Console contains five main pages:
- General parameter: shows the general configuration of business web services and the UDDI Registry's configuration,
- WSDL Section: allows to generate or delete WSDL files, and to deploy the Web Service
- UDDI Section: allows to publish Web Service in UDDI registry, if the UDDI registry has been configured.
- BPEL Deployed Processes
- BPEL Currently Available Instances
