This sample demonstrates the use of the StreamBase Wall Street Systems input and output adapters.

Importing This Sample into StreamBase Studio

In StreamBase Studio, import this sample with the following steps:

  • From the top menu, click File → Load StreamBase Sample.

  • Select this sample from the Embedded Input Adapters list.

  • Click OK.

StreamBase Studio creates a project for this sample.

Sample Location

By default, the sample files are installed in:

On Windows

C:\Program Files\StreamBase Systems\StreamBase.n.m\sample\adapter\embedded\wall-street-systems\

On UNIX

/opt/streambase/sample/adapter/embedded/wall-street-systems/

When you load the sample into StreamBase Studio, Studio copies the sample project's files to your Studio workspace. StreamBase Systems recommends that you use the workspace copy of the sample, especially on UNIX, where you may not have write access to /opt/streambase. In the default installation, the path to this sample in your Studio workspace is: 

UNIX:       
   ~/streambase-studio-n.m-workspace/
      sample_adapter_embedded_wall-street-systems
Windows XP:
   C:\Documents and Settings\username\My Documents\
      StreamBase Studio n.m Workspace\sample_embedded_wall-street-systems
Windows 7 and Windows Vista:
   C:\Users\username\Documents\StreamBase Studio n.m Workspace\
      sample_embeddedwall-street-systems

Running This Sample in StreamBase Studio

Note

To use this sample, you must have access to a valid Wall Street Systems server.

  1. In the Package Explorer view, double-click wall-street-systems.sbapp.

  2. Select the WSSInput adapter icon to open the Properties view for the adapter.

  3. Select the Adapter Properties tab and enter valid values for Host Name, Port Number, Queue Manager, Queue Name, and Channel.

  4. Repeat the previous two steps for the WSSOutput adapter. Enter values for Reply To Queue Manager and Reply To Queue Name as well.

  5. Click the Run button. This opens the SB Test/Debug perspective and starts the application.

  6. In the Test/Debug Perspective, open the Application Output view. If connectivity to your Wall Street Systems server is configured correctly, look for tuples emitted on the InputStatus and OutputStatus streams indicating the adapter has connected successfully.

  7. In the Manual Input view, select the SendMessage stream. Enter one or more values in the sub-fields of the FXTRADE field and press Send Data.

  8. Observe an FXTRADE_RESPONSE tuple emitted on the ReceivedMessage stream.

  9. When done, press F9 or click the Stop Running Application button.

Running This Sample in Terminal Windows

This section describes how to run the sample in UNIX terminal windows or Windows command prompt windows. On Windows, be sure to use the StreamBase Command Prompt from the Start menu as described in the Test/Debug Guide, not the default command prompt.

  1. Open three terminal windows on UNIX, or three StreamBase Command Prompts on Windows. In each window, navigate to the directory where the sample is installed, or to your workspace copy of the sample, as described above.

  2. In window 1, type:

    sbd wall-street-systems.sbapp

  3. In window 2, type:

    sbc dequeue -v

    This window displays the tuples dequeued from the adapters' output ports.

  4. In window 3, send a message to the Wall Street Systems server:

    echo null,"Interface ID,null,null,null,null,null,null,null,null,null,null,null,null" | sbc enqueue SendMessage

  5. Observe in windows 2 an FXTRADE_RESPONSE tuple emitted on the ReceivedMessage stream.

  6. In window 3, type the following command to terminate the server and dequeuer:

    sbadmin shutdown
