Setting up the File Output sample

To set up the sample, complete the following tasks:

Import and deploy the sample. This action adds the following directories to the workspace:
- FileOutputNodeSampleFlowProject. This project contains one sample message flow and one .mbtest file. This project also contains a BAR file containing a compiled message flow.
- FileOutputNodeSampleJavaProject. This project contains the source code for the JavaCompute node that is used in the sample message flow.
Ensure that your default integration node has been created and is running.
Set the MQSI_FILENODES_ROOT_DIRECTORY environment variable to specify the root directory that is used by the FileOutput node.
1. Follow the instructions at Setting up a command environment to create a command environment and a command file that contains the following line (ensuring that there is no white space around the equal (=) sign):
  - On Windows:
```
SET MQSI_FILENODES_ROOT_DIRECTORY=c:\MQSIFileSamples\FileOutput
```
  - On Linux:
```
export MQSI_FILENODES_ROOT_DIRECTORY="/tmp/MQSIFileSamples/FileOutput"
```
  You can replace c:\MQSIFileSamples\FileOutput or "/tmp/MQSIFileSamples/FileOutput" with the path to the directory of your choice.
2. Stop and restart your integration node. See Starting and stopping a broker.

You can now run the sample, see Running the File Output sample.
