Overview of ArcGIS Server Web Services
ArcGIS Java Web Services API Walkthrough
Patterns

ArcGIS Web Services
ArcGIS Server has a rich set of GIS Web Services
You can work with Web Services using the following
AgsJWS API (SOAP)
REST
OGC

WebServices Clients and API’s
ArcGIS Server API (ArcObjects)
ArcGIS Java Web Services API (SOAP)
ArcGIS Server REST API

SOAP Web Services
Easily accessible from Java, .NET, Python, etc.
Cross Platform support, Windows/Linux
Standard Object Orientated programming
Fully integrated into IDE’s

Working with a SOAP Service
Proxy Objects
Communicate with server end points
Call methods on the proxy to execute server-side logic
Value Objects
Native types designed to support input and output from proxy objects

ArcGIS Server: Web Service URL
A Standard Scheme for all SOAP Web Service URL’s
http://<hostname>/<arcgis_instance>/services/<folder>/<service-name>/<service-type>
http://server.arcgisonline.com/arcgis/services/ESRI_StreetMap_World_2D/MapServer?wsdl

ArcGIS Java WebServices API
Coarse Grained
Stateless
Value Objects are based on existing well known ArcObjects types
Types of client applications
Desktop
Web Applications
Web Services

SOAP Web Services
Service Catalog
Map Service
Geocoding Service
Geometry Service
Network Analysis Service
Image Service
Geoprocessing Service
GeoData Service

Service Catalog
Every ArcGIS Server has a Service Catalog Web Service
http://<hostURL>/<arcgis_instance>/services?wsdl

Map Service
Retrieve information about the map
Dynamically generate map images in a variety of image formats
Can get Tile Info or Retrieve Tiles from cache map service
Query and Identify features
Results returned as recordsets
Can return densified and generalized geometries
Can return geometries as KML
Overlay additional information on top of a map

ArcGIS Web Services
SOAP requests are handled by Web Services Handler and forwarded to corresponding Server Object
ArcGIS Java Web Services implements it’s own custom SOAP stack and framework for XML serialization for ArcObjects through JAX-B.
All parameters implement IXMLSerialize
SOAP requests are deserialized and processed by the Server Object
Results are serialized into the corresponding SOAP response
