Wall Street Systems Adapter Sample

Overview

This sample demonstrates the use of the TIBCO StreamBase® Adapters for Wall Street Systems.

IBM MQ Middleware Dependencies

You must obtain the required IBM MQ Java libraries directly from IBM. The easiest way to make the IBM MQ API accessible to StreamBase is to copy the required API JARs into the StreamBase installation in the lib/ext directory.

If copying the JAR files to lib/ext is impractical, then for running IBM MQ adapter applications in StreamBase Studio, you must add the IBM MQ JARs to the Java Build Path. For running IBM MQ adapter applications from the command line, you must add the IBM MQ API JARs to the server's CLASSPATH, either by setting an environment variable, or via the <java-vm> element of the server configuration file.

Obtain the following required IBM MQ JAR files from an IBM MQ Series 7.0 installation, or directly from IBM:

com.ibm.mq.commonservices.jar

com.ibm.mq.headers.jar

com.ibm.mq.jar

com.ibm.mq.jmqi.jar

com.ibm.mq.pcf.jar

connector.jar

Running This Sample in StreamBase Studio

Note

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

In the Package Explorer view, double-click wall-street-systems.sbapp.
Select the WSSInput adapter icon to open the Properties view for the adapter.
Select the Adapter Properties tab and enter valid values for Host Name, Port Number, Queue Manager, Queue Name, and Channel.
Repeat the previous two steps for the WSSOutput adapter. Enter values for Reply To Queue Manager and Reply To Queue Name as well.
Click the Run button. This opens the SB Test/Debug perspective and starts the application.
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.
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.
Observe an FXTRADE_RESPONSE tuple emitted on the ReceivedMessage stream.
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.

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.
In window 1, type:

sbd wall-street-systems.sbapp
In window 2, type:

sbc dequeue -v

This window displays the tuples dequeued from the adapters' output ports.
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
Observe in windows 2 an FXTRADE_RESPONSE tuple emitted on the ReceivedMessage stream.
In window 3, type the following command to terminate the server and dequeuer:

sbadmin shutdown

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

When you load the sample into StreamBase Studio, Studio copies the sample project's files to your Studio workspace, which is normally part of your home directory, with full access rights.

Important

Load this sample in StreamBase Studio, and thereafter use the Studio workspace copy of the sample to run and test it, even when running from the command prompt.

Using the workspace copy of the sample avoids the permission problems that can occur when trying to work with the initially installed location of the sample. The default workspace location for this sample is:

studio-workspace/sample_adapter_embedded_wall-street-systems

See Default Installation Directories for the location of studio-workspace on your system.

In the default TIBCO StreamBase installation, this sample's files are initially installed in:

streambase-install-dir/sample/adapter/embedded/wall-street-systems

See Default Installation Directories for the location of streambase-install-dir on your system. This location may require administrator privileges for write access, depending on your platform.
