I had chance to work on both BPEL and ESB client APIs, and I found very little documentation on BPEL Client API, that made me write this BLOG entry.
BPEL Client API:
Everything we can do in BPELConsole, we can do through BPEL client API as well. BPEL client API is JAR file shipped with SOASuite, I imporeted that JAR file and I could manage my BPEL domain using stand alone Java program which calls this client APIs. Here is the usecase we had to implement: Activating and Deactivating a BPEL process using stand-alone Java program or Servlet.
Here is what I started with:
Here we can see the establishConnection, which takes oc4j server name, port, username and port to connect with BPEL server. I have couple of test service to list all domains, list all services in a domain. I have high-lighted startService and endService which has logic for activating and deactivating the service.
I had to include all libraries from, bpel/lib, opmn/lib and j2ee/home/lib. Once I included these libraries, I was able to run this Java program and activate/deactivate the process successfully.
BPEL Client API source code can be downloaded from here.
ESB Client API:
I found ESB Client API are extreamly well explained and documented, so I avoided repeating that information.
