TwineBallRequest node

Use the TwineBallRequest node to find out how WebSphere® Adapters nodes work.

This topic contains the following sections:

Purpose

The TwineBallRequest node is provided for educational purposes and allows you to see how the WebSphere Adapters nodes work. The TwineBallRequest node is a sample node with its own sample EIS. You cannot use the TwineBall nodes to connect to the external SAP, Siebel, and PeopleSoft EIS systems.

The TwineBallRequest node is contained in the WebSphere Adapters drawer of the message flow node palette, and is represented in the workbench by the following icon:

Configuring the TwineBallRequest node

When you have put an instance of the TwineBallRequest node into a message flow, you can configure it. For more information, see Configuring a message flow node. To display its properties, either double-click the node, or right-click the node and click Properties. All mandatory properties for which you must enter a value (those that do not have a default value defined) are marked with an asterisk.

Terminals and properties

The TwineBallRequest node terminals are described in the following table.

Terminal Description
In The input terminal that accepts the request business object.
Out The output terminal to which the result business object is sent if it represents successful completion of the request, and if further processing is required within this message flow.
Failure The output terminal to which the business object is routed if a failure is detected during processing in the node.

The following tables describe the node properties. The column headed M indicates whether the property is mandatory (marked with an asterisk on the panel if you must enter a value when no default is defined); the column headed C indicates whether the property is configurable (you can change the value when you add the message flow to the bar file to deploy it).

The TwineBallRequest node Description properties are described in the following table.

Property M C Default Description
Node name No No The node type, e.g. TwineBallRequest The name of the node.
Short Description No No   A brief description of the node.
Long Description No No   Text that describes the purpose of the node in the message flow.
The TwineBallRequest node Basic properties are described in the following table.
Property M C Default Description
Adapter component Yes No   The name of the adapter component that contains configuration properties for the adapter. Either enter a name of an adapter file, or click Browse to select an adapter file from the list of files that are available in referenced message set projects.
Default method Yes Yes   The default method binding to use.
The TwineBallRequest node Response Message Parsing properties are described in the following table.
Property M C Default Description
Message domain No No DataObject The domain that is used to parse the incoming message. By default, the message that is propagated from the TwineBallRequest node is in the DataObject domain. You cannot specify a different domain.
Message set Yes No   The name or identifier of the message set in which the incoming message is defined.
Message type No No   The name of the incoming message. The node detects the message type automatically. You cannot set this property.
Message format No No   The name of the physical format of the incoming message. You cannot set this property.
The TwineBallRequest node Transactionality properties are described in the following table.
Property M C Default Description
Transaction mode No No Automatic This property specifies how updates are handled. If you select Yes, updates are performed in a single transaction (coordinated message flows). If you select No, updates are performed independently (uncoordinated message flows).
The TwineBallRequest node Request properties are described in the following table.
Property M C Default Description
Method Location Yes No $LocalEnvironment/Adapter/MethodName The business method that is used to trigger the TwineBallRequest node to perform an action on the external system. For example:
  • createPurchaseOrder causes the TwineBallRequest node to create a purchase order in the EIS.
  • deletePurchaseOrder causes the TwineBallRequest node to delete a purchase order in the EIS.
Data Location Yes No $Body The location in the incoming message tree from which data is retrieved to form the request that is sent from the TwineBallRequest node to the EIS.
The TwineBallRequest node Result properties are described in the following table.
Property M C Default Description
Output data location No No $OutputRoot The message tree location to which the TwineBallRequest node sends output.
Copy local environment No No Selected Select this check box to copy the local environment.
