Invoke BPEL using Java API

This article helps you in kick start of creating your own BPEL console or automate program to do certain activities which BPEL console can perform.

All the operations performed in BPEL console can be created using the java API.

BPEL processes can be invoked using a Java API. The API will differ depending upon the type of operation involved. One way operation has an input message without result. Two way operations send and receive the message.
