# StreamBase to StreamBase Input Adapter Sample

This sample uses the TIBCO StreamBase® SBD-to-SBD Input Adapter in a downstream application to read tuples from an upstream application.

## Importing This Sample into StreamBase Studio

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

- From the top-level menu, click File → Load StreamBase Sample.

- Enter `sbd2` to narrow the list of options.

- Select StreamBase to StreamBase input adapter from the StreamBase Standard Adapters category.

- Click OK.

StreamBase Studio creates a single project containing the sample files.

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

4. In the Manual Input view select the `InputStream` stream, then enter `123` and `abc` into the fields, then click Send Data to send the tuple.

5. In the Output Streams view, observe that the tuples enqueued to the upstream application are emitted by the downstream application.

6. 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

Load this sample in StreamBase Studio, and thereafter use the Studio workspace copy of the sample to run and test it, even when running from the command prompt.

Using the workspace copy of the sample avoids permission problems. The default workspace location for this sample is:

    studio-workspace/sample_adapter_embedded_sbd2sbdinput

See Default Installation Directories for the default location of `studio-workspace` on your system.
