SMILA/Documentation/2011.Simplification

We are currently working in a branch on simplifying some core concepts of SMILA.

The URL of the branch is:

https://dev.eclipse.org/svnroot/rt/org.eclipse.smila/branches/2011-02-24_Simplification

On this page we will link new versions of documentation pages that changed because of these simplifications. When the branch is merged back to the trunk, these pages will replace the normal documentation pages under SMILA/Documentation.

The topics are:

Remove support for Processing Services in BPEL pipelines

The idea behind the distinction between pipelets and processing services was to distinguish between small lightweight processing elements (pipelets) and big ones that require more control on the lifecycle and the used resources. However, we realized that the same goal can be achieved by calling a standard OSGi service via small pipelets. This way the service can have a meaningful interface (instead of having to support a single process() method), the developer has clearer guidance on how to implement the needed functionality and last but not least the implementation of th BPEL engine integration becomes easier.

Replace Tomcat by Jetty 7 as the embedded HTTP server

• Configuration of Jetty based HTTP Server

Simplify Data Model

We also realized that the SMILA data model is too complex to understand and work with. Also it does not really match well to requirements like having to provide JSON based HTTP ReST services which we had in projects using SMILA.
