The Composite Application Editor

What is CASA? This blog provides a general overview of the Composite Application Service Assembly editor, which can simply just be called CASA.

The CASA (Composite Application Service Assembly) editor graphically displays a JBI Service Assembly. It allows the user to see a high-level view of how the Service Assembly is connected and configured. More importantly, users can modify connections between elements within the Service Assembly. The routing of Service Units and Binding Components can be easily tweaked, or completely redone.

Why does CASA exist?

Let us first examine what life would be like without CASA. If there were no CASA, the user could not easily visualize and edit their Service Assembly. It would be difficult for users to detect missing or erroneous internal routing. And even then, creating connections to new components or re-routing existing connections would need to be done by hand, in WSDL.

So we see that CASA makes JBI development easier. But how so?

During the development of SOA projects, CASA removes the need to include binding-specific information in your WSDL files. Thus, in your BPEL / EJB / XSLT / etc. projects, you can focus on writing the abstract interconnection logic without the concrete network protocol information. CASA generates all the necessary concrete WSDL elements automatically.

Where can I get CASA?

CASA is just one element of Open ESB. You can access the download page here: Open ESB.
