GVConnectorConfiguration

Description

This Adapter represents the GreenVulcano^® ESB client API configuration.

VulCon / GV Console Configuration

Configuration is made up of three sections:

• ConnectorServices: Contains information to identify the communication channel, according to the couple service/system or only to the service.
  Moreover, for each primitive (request, request/reply, etc.), this section declares also the extensions to invoke. For services not covered by the parameters defined in this section is used the default channel, without applying any extension.

• Extensions: Extensions are pre/post processing data that can be made by the connector immediately before invoking GreenVulcano^® ESB and/or immediately before returning the result to the caller.

• Channels: This section defines the connection parameters to GreenVulcano^® ESB. Typically there is a single channel of communication to all GreenVulcano^® ESB services required by the client. However, for special needs, you can define several channels for different services.

The following table shows the GVConnectorConfiguration's attributes:

Attribute	Type	Description
type	fixed	This attribute must assume the value module
name	fixed	This attribute must assume the value GV_CONNECTOR_J

The GVConnectorConfiguration adapter allows the following subelements:

• Description
• ConnectorServices
• Extensions
• Channels
• Transactions
• ExternalComponents

ConnectorServices

Configuration details for services and calls.

The ConnectorServices Element is used by GVConnectorConfiguration.

It has the subelements:

• Description
• ConnectorService
• Call

ConnectorService

Service configuration details.

The ConnectorService Element is used by: ConnectorServices.

The following table show the element's attributes ConnectorService:

Attribute	Type	Description
id-service	required	Service identifier. The attribute's value can't be null.
id-channel	optional	Channel for this service. If not defined a default channel is used.
id-system	optional	System identifier. If defined, you apply the parameters to the couple system/service, otherwise the parameters apply to service, independently from the value of the field System.

It has the subelements:

• Description
• OperationDetails

OperationDetails

Specific operation detail.

The OperationDetails Element is used by ConnectorService.

The following table show the element's attributes OperationDetails:

Attribute	Type	Description
id-operation	required	Operation id. The attribute's admitted values are: Request RequestReply GetReply GetRequest SendReply ReceiveMessage SendMessage
id-extension	optional	Extension applied to the invocation of the operation.

Extensions

Definition of Extensions.

Extensions are pre / post processing of data that can be made automatically from the connector before invoking GreenVulcano^® ESB and/or before returning the result to the caller.

The Extensions Element is used by GVConnectorConfiguration.

It has the subelements:

• Description
• ComplexExtension | TestExtension | CompressExtension | DecompressExtension | DecryptExtension | EncryptExtension | DTEExtension

ComplexExtension

Allows you to combine with several extensions.

Moreover for any extension you can define when it has to be applied (IN, OUT or INOUT). The output extensions are applied inversely to the declaration order.

The ComplexExtension Element is used by Extensions.

The following table show the element's attributes ComplexExtension:

Attribute	Type	Description
type	fixed	Unmodifiable. Used by GreenVulcano® ESB factory framework. This attribute must assume the value extension.
class	fixed	This attribute must assume the value it.greenvulcano.gvesb.connector.extensions.ComplexExtension.
id-ext	required	The attribute's value can't be null.

It has the subelements:

• Description
• Extension

TestExtension

Test extension used only to debug the connector

The TestExtension Element is used by Extensions.

The following table show the element's attributes TestExtension:

Attribute	Type	Description
type	fixed	Unmodifiable. Used by GreenVulcano® ESB factory framework. This attribute must assume the value extension.
class	fixed	This attribute must assume the value tests.unit.gvconnector.ExtensionTestClass.
id-ext	required	The attribute's value can't be null.
when	optional	The attribute's default value is: inout. The attribute's admitted values are: in out inout
prefix	optional
suffix	optional
