5 BPEL Process Manager Integration Examples

Design Time

Creating a Channel

You must create a separate channel for every inbound J2CA service and select that channel when you generate WSDL for inbound interaction using Application Explorer.

To create a channel:

1. Click the Events node.

2. Expand the PeopleSoft node.

   The ports and channels nodes appear in the left pane.

   
   Description of the illustration addchannel.gif
   
   

3. Right-click Channels and select Add Channel.

   The Add Channel dialog box is displayed.

   
   Description of the illustration addchannel_2.gif
   
   

   Provide the following information:

   1. Enter a name for the channel, for example, PSFT_Channel.

   2. Enter a brief description (optional).

   3. From the Protocol list, select HTTP Listener.

4. Click Next.

5. When the Basic dialog box is displayed, enter the system information as specified in the following table:

   Parameter	Description
   Port	Port on which to listen for PeopleSoft event data.
   Server port	Port on which the host database is listening.
   Synchronization Type	Choose from three synchronization options:REQUESTREQUEST_RESPONSEREQUEST_ACK

   
   

6. Click OK.

   The channel appears under the channels node in the left pane. An X over the icon indicates that the channel is currently disconnected.

   
   

   Note: Do not start the channel, as it is managed by BPEL PM Server. If you start the channel for testing and debugging purposes, stop it before runtime.

   
   

Creating an Event

After you create a channel and verify that it is not started, you must create an event using Application Explorer.

To establish a connection to the PeopleSoft system and locate LOCATION:

1. Start Application Explorer.

2. Expand the Adapters node.

   A list of all available adapters is displayed.

3. Expand PeopleSoft.

4. Click a target name under the PeopleSoft node, for example, PSFTtarget.

   The Logon pane on the right displays the saved parameters.

5. Verify your connection parameters and provide the required password.

6. Right-click the target name and select Connect.

   The x icon disappears, indicating that the target is connected.

   
   Description of the illustration select_psft.gif
   
   

7. Expand Messages and select LOCATION_SYNC.VERSION_1.

8. Right-click LOCATION_SYNC.VERSION_1.
