About This Sample

This adapter sample illustrates the use of the TIBCO StreamBase® Text File Reader Adapter by reading a file and emitting a tuple that contains the file's contents in a string field.

Importing This Sample into StreamBase Studio

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

  • From the top-level menu, select FileLoad StreamBase Sample.

StreamBase Studio creates a project for the sample.

Running filereader.sbapp in StreamBase Studio

  1. In the Project Explorer, open the sample you just loaded.

  2. Open the src/main/eventflow folder.

  3. Open the package folder (most samples contain a single package folder. Open the top-level package folder if your sample contains more than one folder).

  4. Open the named application file and click the Run button. This opens the SB Test/Debug perspective and starts the application.

    If you see red marks, wait a moment for the project in Studio to load its features.

    If red marks do not resolve themselves in a moment, select the project and right-click MavenUpdate Project from the context menu.

  5. In the Manual Input view, click Send Data to send the default null tuple.

  6. In the Application Output view, observe tuples emitted on the Status and Data output streams, the latter of which contains the contents of the configured default file, MyFile.txt.

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