Description

The element GVWebServices allows to define the Web Services implemented by GreenVulcano® ESB.

VulCon / GV Console Configuration

The GVWebServices Element is present in the VulCon Adapter view, as a GVAdapters subelement.

The following table shows GVWebServices element's attributes:

Attribute Type Description
version fixed This attribute must assume the value 1.0.
type fixed This attribute must assume the value module.
name fixed This attribute must assume the value WEB_SERVICES.

Its subelements are:

The GreenVulcano® ESB service input GVBuffer contains the following properties:

  • WS_SERVICE : name of the invoked webservice
  • WS_OPERATION : name of the invoked webservice's operation
  • WS_REMOTE_ADDR : remote address of the invoking client
  • WS_CONTENT_TYPE : request content type
  • WS_REQ_SOAP_VERSION : request SOAP version URI

GreenVulcanoWebServices

You can expose a GreenVulcano® ESB core through the configuration of a generic Web Service. This element represents the GreenVulcano® ESB Web Services definition.

You can retrieve the WSDL at the address:
http://<host>:<port>/gvaxis2/services/GreenVulcanoWebservice?wsdl
Attribute Type Description
gv-service required Service name with which to perform the invocation of GreenVulcano ESB..
gv-operation required GreenVulcano ESB operation to invoke.
transacted optional Indicates whether the invocation to be performed in GreenVulcano is transactional or not.

Default: false

A transaction is rolled back if:

  • the service ends with exception
  • the output SOAP response is a Fault
  • the output GVBuffer contains the property WS_FORCE_TX_ROLLBACK=Y
tx-timeout optional Transaction timeout in seconds.

Default: 30s

force-https optional Indicates whether the protocol is https or not.

Default: false

intput-dp optional DataProvider be used to process input data.
output-dp optional DataProvider be used to process response data.

The following table shows the BusinessWebServices element's attributes:

Attribute Type Description
wsdl-directory required Directory containing the generated WSDL for the services exposed through Axis2.
services-directory required Directory containing the services generated from a WSDL using Axis2.
authenticated-http-soap-address optional This is the default URL that is used to build the soap:

address for Web Services that require authentication exposed with http protocol. This URL can be overridden on different services. If not specified will be required to define it on the services. The final URL will be formed by concatenating the name of the service: default-soap-address/service

authenticated-https-soap-address optional This is the default URL that is used in the build the soap:address for web services that require authentication exposed with https protocol.

This URL can be overridden on different services. If not specified will be required to define it on the services. The final URL will be formed by concatenating the name of the service: default-soap-address/service

http-soap-address optional This is the default URL that is used in the build the soap:address for web services that not require authentication exposed with http protocol.

This URL can be overridden on different services. If not specified will be required to define it on the services. The final URL will be formed by concatenating the name of the service: default-soap-address/service
