Definition
A dh-call is the operation that must be configured into VulCon® or GV Console® System section, to define the parameters for making a call to the DataHandler.
The DBOBuilder to be invoked is defined by:
- the input GVBuffer DH_SERVICE_NAME property value
- the input GVBuffer.service field value
VulCon / GV Console Configuration
In order to add a dh-call operation you must define the following fields:
| Attribute | Type | Description |
|---|---|---|
| type | fixed | This attribute must assume the value call. |
| class | fixed | This attribute must assume the value it.greenvulcano.gvesb.virtual.datahandler.DataHandlerCallOperation |
| name | required | This field identifies the operation name that you will use in service definition. |
The following example shows the configuration generated from VulCon® or GV Console® when you configure a dh-call operation:
<?xml version="1.0" encoding="UTF-8"?>
<GVSystems name="SYSTEMS" type="module">
<Systems>
<System id-system="system-name" system-activation="on">
<Channel id-channel="CHANNEL_NAME">
<dh-call class="it.greenvulcano.gvesb.virtual.datahandler.DataHandlerCallOperation"
name="TestInsertXML" type="call"/>
</Channel>
</System>
</Systems>
</GVSystems>
To use a dh-call in a GreenVulcano® ESB service, you need to define a node of type GVOperationNode into your Service element and define in the field operation-name the name defined in the dh-call operation.
The following example shows the configuration generated from VulCon® or GV Console® when you configure a dh-call operation in GreenVulcano® ESB service:
<?xml version="1.0" encoding="UTF-8"?>
<GVServices name="SERVICES" type="module">
<Groups>
<Group group-activation="on" id-group="DEFAULT_GRP"/>
</Groups>
<Services>
<Service group-name="DEFAULT_GRP" id-service="SERVICE-NAME"
service-activation="on">
<Client id-system="SYSTEM-NAME" statistics="off" system-activation="on">
<Operation name="RequestReply" operation-activation="on"
out-check-type="none" type="operation">
<Participant id-channel="CHANNEL-NAME" id-system="SYSTEM-NAME"/>
<Flow first-node="excel_reader" point-x="20" point-y="112">
<GVOperationNode
class="it.greenvulcano.gvesb.core.flow.GVOperationNode"
dump-in-out="false" id="process"
id-system="GVESB" input="input"
next-node-id="end" op-type="call"
operation-name="TestInsertXML" output="output"
point-x="127" point-y="139" type="flow-node"/>
<GVEndNode class="it.greenvulcano.gvesb.core.flow.GVEndNode"
end-business-process="yes" id="end" op-type="end"
output="excel_xml" point-x="358" point-y="112"
type="flow-node"/>
</Flow>
</Operation>
</Client>
</Service>
</Services>
</GVServices>
At this point you have configured a service with a dh-call operation.
Into the dh-call it is possible to insert three elements:
