For educational purposes I’ve created a cookbook in powerpoint format on how to create a simple decision table in Oracle SOA Suite with a Business Rule engine.
To share this I’ve uploaded it to slideshare and post it here in the Amis blog as well.
Additional remark: xml-, xsd- and wsdl-files which are used or referenced by more than one composite or by the outside world are stored in the Meta Data Storage (MDS). This prevents having copies of the same file in projects with the risk that files become out of sync in case of changes.
Only files which are used inside one composite only (inner composite usage) are normally stored in the project of the composite.
A more difficult example of a Business Rule Engine in the Oracle SOA Suite can be found here.
