The OData Application is implemented in the OData Library (Core) and registers a root locator and an exception mapper.

In addition the root locator looks up a parameter <code>org.apache.olingo.odata2.path.split</code> (not present in the deployment descriptor above) which indicates how many path segments are reserved for the OData Service via an Integer value (default is 0, which means that the OData Service name corresponds to the defined <code>url-pattern</code>). </p> +</li> +</ul> +<h3
