# Configuring the Discovery Framework on Tomcat to work with IAP 6.1.4

This topic describes how to configure a Discovery Framework implementation running on Tomcat to work with IAP 6.1.4.

To configure the Discovery Framework on Tomcat to work with IAP 6.1.4:

Copy the 6.1.4 endeca_navigation.jar file to the tomcat-<version>/lib/ext directory. This overwrites the existing version of endeca_navigation.jar.

All 6.1.4 MDEX Engine features automatically work in the Discovery Framework. However, there is no built-in support for the 6.1.4 Presentation API features. To expose the new features, you have to add your own QueryFunction using the QueryFunction extension point, or manipulate the ENEQuery directly within the component.
