DataMapper: Supplemental Topics (Deprecated - DataMapper)

DataMapper continues to be fully supported in all current and future versions of Mule 3.x, however it will be removed in Mule 4.0 in favor of the Transform Message component (based on DataWeave code). We recommend that if you wish to take advantage of the new capabilities of DataWeave or if you start new projects, upgrade now.

A migration tool is now included in Anypoint Studio, which assists in converting a DataMapper map to DataWeave. From the Anypoint Studio Canvas, right-click a DataMapper building block, select Migrate to DataWeave, and follow the instructions.

If you don’t see DataMapper on your palette, you can enable it by going to Preferences > Anypoint Studio > Palette Profiles and clicking the checkbox Show deprecated Mule Components and Attributes.

The following topics are likely to be of interest to advanced users of the Anypoint DataMapper Transformer.
