Web Server Request And Response Input and Output Adapter Samples

About The Samples

In these samples, the TIBCO StreamBase® Web Server Request input adapter and TIBCO StreamBase® Web Server Response output adapter work together to serve up HTTP content, response to AJAX queries, web sockets, file downloads, and file uploads.

When you start this sample, a web server is created on port 8080. This web server will server up the demo web site to demonstrate the various requests that can be performed against this server.

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.

Running webserver.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. For the example, open a web browser to http://localhost:8080

  6. In the Application Output view, observe tuples emitted on the RequestData and ResponseData output streams.

  7. Select the tuple emitted from the RequestData and ResponseData streams, then use the triangles next to the data fields displayed to analyze and understand their structure.

  8. Now on the demo web page severed by this example try various operations and observe the results on the web page, and in Studio.

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

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