FTP Operator Sample

About This Sample

This operator sample illustrates the use of the TIBCO StreamBase® operator for FTP by sending an FTP client GET command to an FTP server to retrieve a file.

Running This Sample in StreamBase Studio

  1. First, ensure that you have imported the sample by following the section above: Importing This Sample into StreamBase Studio.

  2. This sample is ready to run out of the box. Click the Run button to start the application and enter the SB Test/Debug perspective.

    Enter no values and press Send Data.

  3. Press F9 or click the Stop Running Application button.

  4. Refresh your project, by selecting the project from the resource menu and pressing F5.

    You should notice that there is now a new file in your project. This was the file retrieved via the FTP GET command.

  5. Restart the application

    In the field cmd, enter the value FREE_FORM and press Send Data.

    You should see, in the Output Streams tab, that the object field contains two numbers. The first is the server response code and the second is the size of the file that you just retrieved, in bytes.

  6. Experiment with different values for cmd, local, remote and the operator properties.

    If you want to have more functionality, be sure to change the Server hostname, Username and Password operator properties to a server on which you have write access.
