Using the MetaData Services (MDS) in a SOA environment by Robert van Molken

It has been almost a year since my last post about the metadata services. I talked about how-to set up a File-based MDS and DB-based MDS. This post talks about the usage of the files, placed in the MDS, in the different components available in a SOA composite. If the MDS is a new thing for you then I advise to read my previous about this subject first.

You can spot the presence of a file that is a reference to the MDS if it uses the oramds: URI annotation. Files are no longer referenced to a hardcoded or relative file path.

To start using you’re MDS that you have set up we will create a new SOA application. Let call the application WorkflowSOAapp and create a SOA project and call it WebformService.

Use MDS resources for exposed services

After creating the new SOA project it will open the composite editor automatically. Exposed services are always created in the left swim lane. Because this project deals with a WSDL resource to expose a webservice, a Web Service component is first dragged to the left swim lane.

Drag Web Service Component to left swimlane

A dialog “Create Web Service” will open. Give the service a good name, preferred the same as the name in the WSDL (e.g. WebFormService). The next thing to do is to choose the WSDL URL. Click on the document icon at the right side of the WSDL URL input to find an existing WSDL. Read the full article here & Read part II here.
