# Installing the Discovery Framework on the WebSphere Application Server version 6.1

You can deploy the Discovery Framework as a standalone application on WebSphere Application Server (WAS) version 6.1. (6.1.0.1 or higher).

Before following the steps here, consult the Liferay Portal Administrator's Guide, which contains portal deployment instructions and examples for WebSphere Application Server 6.1.

Note: The examples in this section are based on a Linux server WAS deployment. If you are installing on Windows, the steps will be similar, though you will need to substitute Windows executables and paths. In certain examples, backslashes are used to escape the dollar sign ($) character on Linux, because the shell would otherwise attempt a variable substitution for this character. These backslashes should not be required on a Windows system.
Note: Among the data sources in your Discovery Framework application, you must always include a default data source. This data source is automatically assigned to all data-source-backed components when they are initially added to a page. For details, see the topic "Specifying a default data source," located in the chapter "About data source configuration."
Note: When the Discovery Framework is running on WAS 6.1 on Linux, some of its administrative components require the compat-libstdc++-33 library to function. If this library is not already installed, you can install it with a command such as `yum install compat-libstdc++-33.` For more information, see the IBM WebSphere documentation.
