Using custom Java functionality during mapping
When mapping a source field to a target field, the mapping editor provides an option called Custom Java.
You can use the Custom Java option to add application-specific calculations and functions, such as converting XSD date values to MDM-specific date values or transcoding a source reference value to a reference value that is usable by InfoSphere® MDM.
The Custom Java construct requires a callout to a Java class. The Java class must be accessible to the mapping project.
For utility classes or methods that need to be used by different mapping projects, you can create a composite bundle comprised of the utility component classes, and then export the library packages. You can then later import these library packages for use in other mapping projects.
