File Template Sample

About This Sample

This sample illustrates the use of the TIBCO StreamBase® File Reader Adapter and TIBCO StreamBase® File Writer Adapter working together to read a templated file into the system and use the inbound tuple to replace values in the read file and then write that information back out to another file.

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.

  • Type filet to narrow the list of options.

  • Select File reader input adapter using replacement fields to write a template file output from the StreamBase Standard Adapters category.

  • Click OK.

StreamBase Studio creates a project for the sample.

Running TemplatedReadWrite.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, fill out the fields available and then click Send Data.

  6. In the Application Output view, observe tuples emitted on the ReadStatus and Data output streams.

  7. Repeat the process and send as many tuples as desired to test the functionality.

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

  9. The sample application produces an Output.txt file in your node's temp folder with the results formatted per the Template.txt template file.
