Instead of building legend editing into GeoNetWeaver we opted instead to use MapWindow GIS to create and edit the legend.  MapWindow GIS is a very well supported open source project.  It is installed when GeoNetWeaver is installed.

To extract a MapWindow GIS project file from a GeoNetWeaver geoproject:
  - Open the geoproject in GeoNetWeaver
  - Open the [[netweaver:windows:geonetweaver setup|geoproject editor]] from the Edit|Setup... menu.
  - Press the "next" button until you are at the last page, the "Legend" page.
  - Press the "export" button to export the legend to a MapWindow GIS project file.

To import a MapWindow GIS project file into a GeoNetWeaver geoproject:
  - Open the geoproject in GeoNetWeaver
  - Open the [[netweaver:windows:geonetweaver setup|geoproject editor]] from the Edit|Setup... menu.
  - Press the "next" button until you are at the last page, the "Legend" page.
  - Press the "import" button to import your new legend to a MapWindow GIS project file.
When importing a MapWindow GIS project file any existing legend in the geoproject is overwritten.
