Identifying the Client Channel in a Service Call

Most WorkPresentationService calls require you to identify the channel to be used.

The service call from WorkPresentationService) passes the following items in the request message:

• channelId is the identifier of the channel to which the client is bound.
• channelType is an enumerated value associated with that channel type.

The following table shows:

• the channel types supported by TIBCO Business Studio.
• the format of different channelIds used to identify individual channels of each presentation type. ChannelName is the label of the parent presentation channel - for example, DefaultChannel or CustChannel1.
• the channelType enumeration that should be specified for each channelId.

  TIBCO Business Studio channel type	channelId	channelType
  Openspace Google Web Toolkit	openspaceGWTPull_ChannelName	openspaceChannel
  Workspace Google Web Toolkit	GIGWTPull_ChannelName	openspaceChannel
  Openspace Mobile	MobileGWTPull_ChannelName	MobileChannel
  Openspace Email	openspaceEmailPush_ChannelName	EmailChannel
  Workspace Email	EmailGIPush_ChannelName	EmailChannel

  Note: The channelType enumerations JSPChannel, PageflowChannel and RssChannel are currently not supported.

You cannot obtain channelIds programmatically. Instead, you must obtain them directly from TIBCO Business Studio. The following screenshot shows:

• the channel types used by the default presentation channel. (Form artifacts are automatically generated for each of these channel types.)
• how to obtain the channelId of a particular channel. In this example, openspaceGWTPull_DefaultChannel identifies the channel in the Default Channel presentation channel that uses the Openspace Google Web Toolkit channel type.

Note: See "Using Presentation Channels to Display Tasks to Users" in TIBCO Business Studio BPM Implementation for more information.
