SERVICEINFO

SERVICEINFO

Examples

Used in: RESPONSE
Parent elements: RESPONSE

<SERVICEINFO > No Attributes (m) <LAYERINFO... /> <ENVIRONMENT... /> <PROPERTIES... /> </SERVICEINFO >
Bold: Attribute or child element is required. (m): Child element can be used multiple times.

Description:

Provides details about each layer in a MapService. If the layer data source is an image such as TIFF, only minimum and maximum extent is returned in the response. If the layer is a vector data source, additional information is returned such as the type of feature, feature geometry, rendering and symbolization, and extension parameters.

Restrictions:

When using an ArcIMS HTML Viewer, ArcIMS Java Viewer, ArcExplorer 3, or any other browser using the ArcIMS Servlet Connector, several elements in a SERVICEINFO response are restricted.
- In RASTERMARKERSYMBOL, RASTERFILLSYMBOL, and RASTERSHIELDSYMBOL, the attribute image is not returned.
- OUTPUT is not included in the SERVICEINFO response, even if it is included in the map configuration file.
These restrictions can be lifted by setting the property spatialServer.AllowResponsePath to true in esrimap_prop. This property file is found in the servlet engine directory. For more information on the location of esrimap_prop and its properties, see the topic "Administering the ArcIMS Servlet Connector" in the System Administration chapter of the ArcIMS Help Contents.

These restrictions apply only when the ArcIMS Servlet Connector is used. They do not apply to the ActiveX or ColdFusion Connectors or to other connectors using the ArcIMS Application Server Link.

Notes:

See GET_SERVICE_INFO for request.
SERVICEINFO element contains a LAYERINFO child element for each layer defined in the MapService.
All layer fields are described in FCLASS child element including the layer’s envelope and all available fields.
If any extensions were defined for a LAYER in a map configuration file, then information about all these extensions is also returned in EXTENSION elements.
For more details on using GET_SERVICE_INFO and SERVICEINFO including additional examples, see Using GET_SERVICE_INFO and SERVICEINFO.

Examples for SERVICEINFO:

Example 1: When layer rendering is included and RASTERFILLSYMBOL is restricted.
