## Overview
The Contivo Transformation filter uses the Liaison Contivo engine to transform messages into an alternative format. First you use the Contivo Analyst tool to define the mappings required for your transformation For example, a specific XML element is placed into a specific field in a COBOL message. In Contivo Analyst, when your mappings are defined, you automatically generate Java code, which must be placed on the Enterprise Gateway classpath. This topic explains how to add the generated Java code to the Enterprise Gateway classpath.
## Configuration
Complete the following fields to configure the Contivo Transformation filter: Name: Enter an appropriate name for this filter. Transform Class Name: Contivo Analsyt generates a Java class file that performs the transformation. You must place this class on the Enterprise Gateway classpath by copying the associated class file into the `INSTALL_DIR/ext/lib` directory, where `INSTALL_DIR` points to the root of your product installation. Enter the name of the class in this field. Source FFD: Contivo Analyst generates a Fixed File Descriptor (FFD) that describes the format of the source message to be transformed by the Contivo engine. Browse to the location of this file using the Browse button. Target FFD: Contivo Analyst also generates a Fixed File Descriptor (FFD) for the target message, which is the message generated by the Contivo engine. Browse to the location of this file using the Browse button. Transformed Content Type: Enter the Content-type of the target message used by the Enterprise Gateway when routing the output of the transformation on to the target Web Service.
