One of our customers operates an ArcGIS Server using Oracle as DBMS. We would like to introduce a RESTful WebService as high level interface for our Wicket application. However, some custom data has both to be processed and returned, so we need to implement additional business logic. As far as we can see, 'Relational Catalog Services' are closest to our requirements:
They provide means to extract tuples from the database but do not support additional data processing.
Is it possible to develop custom Java WebServices (e.g. based on JAX-RS) and deploy them on ArcGIS Server?
