Receiving Various Messages to Start a Process
Introduction
This sample demonstrates how to start a process when the message exchange involves different incoming messages and/or multiple partner links.
In this example, two different types of messages are received over two different partner links. The process consists of the following:
- Two sequence activities, each containing a receive-reply activity pair with an assign in between.
- The receives handle different message types and have the
"createInstance" attribute set to yes
- The two types of messages that the process handles are a custom order message and a UBL order message. UBL is the Universal Business Language, a "generic XML interchange format for business documents that can be extended to meet the requirements of particular industries." UBL is published by the same organization that publishes the BPEL specification, OASIS.
- The assigns each create an acknowledgment response message corresponding to the received message. Each response message includes data from the received message.
- The reply activities send the response messages back via the same partner link through which the received message arrived.
The following diagram represents the process. Note that the process may directly contain only one activity. The process contains an implicit flow primary activity that contains the two sequence activities. The flow activity is hidden (to save space) because ActiveBPEL Designer has added it automatically.
Deploying the Process
Running the Process
The OASIS-provided sample ublOrderMessage.xml does not comply with their schema. Therefore, you must disable validation before simulating the process in ActiveBPEL Designer or running it in the ActiveBPEL engine or an ActiveBPEL Server. This is done by un-checking the "Validate Input/Output messages against schema" option:
- For ActiveBPEL Designer, visit "Window > Preferences > ActiveBPEL > Simulation".
- For the ActiveBPEL Server, visit the administration console's "Configuration" page.
To run the sample, see Running
the
Samples. There are two separate services, one for the order process
message and one for the UBL order message. For the order process
message, use
the service name orderProcessPLTService and the sample data file
orderMessage.xml. For the UBL order message, use the
service name
ublOrderPLTService and the sample data file
ublOrderMessage117.xml (not
ublOrderMessage.xml).
