To Call a Business Process From a POJO Service

Before You Begin

This task requires that the business process being called is already created. For information on creating a business process, see BPEL Designer and Service Engine User’s Guide.

Create the business process with any necessary activities and WSDL documents.

For more information about creating business processes, see the BPEL Designer and Service Engine User’s Guide.

Create a new Java Application project for a POJO consumer, as described under Creating a POJO Service Consumer (Without Binding) or Creating a POJO Service Consumer (With Binding).

Standard code is automatically generated for the consumer.

Modify the code between the Consumer Invoke comments to handle the input from the business process.

Below is a simple example of adding a response string to the message received from the business process.

@Operation (outMessageTypeQN="{http://jseecho/Echo/}EchoOperationResponse")
public String receive(String input) {
    /* Consumer Invoke - Begin */
    {
        String inputMessage = null;
        try {
            String outputMsg = (String) sepEchoInterfaceEchoOperation.
                   sendSynchInOut(inputMessage, org.glassfish.openesb.pojose.
                   api.Consumer.MessageObjectType.String);
            return "Hello from POJO: " + outputMsg;
        } catch (Exception ex) {
            ex.printStackTrace();
        }
    } /* Consumer Invoke - End */
    return "Hello from POJO: " + input;
}
// Logger
private static final Logger logger = Logger.getLogger(Echo.class.getName());
// POJO Context
@Resource
private Context jbiCtx;
@ConsumerEndpoint(serviceQN = 
   "{http://jseecho/Echo/}epEchoInterfaceEchoOperatioService",
   interfaceQN = "{http://jseecho/Echo/}EchoInterface", 
   name = "epEchoInterfaceEchoOperatio", 
   operationQN = "{http://jseecho/Echo/}EchoOperation", 
   inMessageTypeQN = "{http://jseecho/Echo/}EchoOperationRequest")
   private Consumer sepEchoInterfaceEchoOperation;
