# 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 File → Load StreamBase Sample.

- Enter `webser` to narrow the list of options.

- Select Web Server Request Response adapters from the StreamBase Standard Adapters category.

- Click OK.

StreamBase Studio creates a project for the sample.

## 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 `webserver.sbapp` file and click the Run button. This opens the SB Test/Debug perspective and starts the module.

4. For the example, open a web browser to `http://localhost:8080`

5. In the Output Streams view, observe tuples emitted on the RequestData and ResponseData output streams.

6. 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.

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

8. When done, press F9 or click the Terminate EventFlow Fragment button.

## Sample Location

When you load the sample into StreamBase Studio, Studio copies the sample project's files to your Studio workspace, which is normally part of your home directory, with full access rights.

### Important
