Running This Sample in StreamBase Studio

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

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

    If the red marks do not resolve themselves after a minute, select the project, right-click, and select Maven>Update Project from the context menu.

  2. Open the src/main/eventflow/packageName folder.

  3. Open the filereader.sbapp file and click the Run button. This opens the SB Test/Debug perspective and starts the module.

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

  5. In the Output Streams 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.

  6. Press F9 or click the Terminate EventFlow Fragment button.
