How to create asynchronous BPEL process in SOA
In the asynchronous process two one way operations ports are defined to receive the request and send the response. On the client side, the client uses the invoke activity to invoke the asynchronous BPEL process and continues with its flow. It uses the receive activity to receive the response later in the flow. The asynchronous…
How to create Synchronous BPEL process in SOA
The synchronous process defines one two-way operation port to receive the request and send the response back. Using the invoke activity, client invokes Synchronous BPEL process on this port and waits to receive response on the same port. As soon as the client receives response from BPEL process it continues with its flow. On the…
Asynchronous vs Synchronous BPEL process in SOA
This article explains the difference between an asynchronous and a synchronous process with the help of a simple example below: Suppose there are two processes SynchronousBPELProcess and AsynchronousBPELProcess. Also, there is a third process which we’ll call as Client. The Client invokes the above processes. If client invokes SynchronousBPELProcess. Client…
