Sample Location

This sample demonstrates the use of the TIBCO StreamBase® CSV Socket Reader to read CSV data from a TCP socket. The CSV Socket Reader is configured to connect to a server running on port 9000 of the local computer to read CSV data. The sample comes with a very simple server written in Java. The source code and compiled JAR of this server can be found in the sample's directory. The server simply listens on port 9000 and serves the contents of a file at one line per second to any connections. The default input file is input.txt, but you can specify a different file on the command line that starts the server.

Running This Sample in StreamBase Studio

  1. Open a terminal window on UNIX, or a StreamBase Command Prompt on Windows, outside of StreamBase Studio.

  2. In the window, navigate to the directory where the sample is installed, or to your workspace copy of the sample, as described above

  3. In the window, run the sample server with this command: java -jar simpleserver.jar

  4. In the Package Explorer, double-click to open the CSVSocketReader.sbapp application. Make sure the application is the currently active tab in the EventFlow Editor.

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

  6. As the server sends lines of the input file to the application, they will appear in the Application Output pane.

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

  8. In the window running simpleserver, press Ctrl+C to stop the server.

Running This Sample in Terminal Windows

  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, run the sample server with this command: java -jar simpleserver.jar

  3. In window 2, run sbd CSVSocketReader.sbapp

  4. In window 3, run sbc dequeue OutputStream1

  5. Look for the processed tuples being output in window 3, one tuple per second.

  6. When done, run sbadmin shutdown

  7. In the window running simpleserver, press Ctrl+C to stop the server.

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_csvsocketreader

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/csvsocketreader

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