Wait for Adapter Message

See Scalability With Incoming Events in TIBCO ActiveMatrix BusinessWorks Process Design Guide for information on running the "Wait for..." activities in a multi-engine mode.

Figure 7 illustrates an adapter publishing service publishing a message and the Wait for Adapter Message activity receiving the message in a business process.

Field	Global Var?	Description
Name	No	The name to appear as the label for the activity in the process definition.
Description	No	Short description of the activity.
Adapter Service	No	The preconfigured adapter publishing service. You must specify the adapter service when configuring the adapter. Use the Browse button to locate the appropriate service for this activity.
Custom AESchema	No	Specifies whether you want to supply a class for this activity’s output.
Custom AESchema Reference	No	Only appears when the Custom AESchema field is checked. This field specifies the TIBCO ActiveEnterprise schema to use for the body of the message in the output of this activity.

Field	Description
Candidate Event Key	Expression built from the data of the incoming message. This expression should evaluate to a string and it is compared to the "key" field of the activity’s input. If the Candidate Event Key and the activity’s key match, then the process accepts the incoming message. For example, you may have a Publish to Adapter activity that sends a message with a particular ID. You are expecting a reply message that contains that same ID so that you can determine the message is a response to your sent message. You would specify the field of the incoming message that contains your ID in the Candidate Event Key. You would then use the message ID of the message you sent earlier in the process as the "key" field in the input. This expression is specified in XPath, and only data from the incoming event is available for use in this XPath expression. See TIBCO ActiveMatrix BusinessWorks Process Design for more information about XPath expressions.
Event Timeout (msec)	A message may arrive before this activity is executed. This field specifies the amount of time (in milliseconds) a message waits if it is received before this activity is executed. If the event timeout expires, an error is logged and the event is discarded. If no value is specified in this field, the message waits indefinitely. If zero is specified, the event is discarded immediately, unless this activity has already been reached.

Input Item	Datatype	Description
key	string	The value that is compared to the Candidate Event Key field of the Event tab to determine if this message applies to this process. See Event for an example of using the Candidate Event Key field with the key input item.
processTimeout	integer	The time (in milliseconds) to wait for the incoming message. An error is returned if the message is not received in this time limit.

Output Item	Datatype	Description
subject	string	The subject of the message.
replySubject	string	The reply subject of the message.
certifiedSequenceNumber	string	This element is only available when Tibrv Certified is the transport. This element contains the sequence number in which this message was received.
certifiedSender	string	This element is only available when Tibrv Certified is the transport. This element contains the cmname of the message sender.
trackingInfo	complex	The AE tracking info of the sender. This element contains the tracking ID and appInfo sent by the application.
body	complex	The class specified for the publication service of the specified adapter configuration or in the Custom AESchema Reference field on the Configuration tab.

Exception	Thrown When...
ActivityTimedOutException	The specified processTimeout has been reached.
TransportException	The transport cannot be created.
DeserializationException	The outgoing reply cannot be serialized.
ConfirmationException	The message could not be confirmed.
