i'm upgrading the Openjump ArcheOS-deb-package. I will upload the new file as soon as possible, after an hard test on different computers. I'm working with the new version since a couple of weeks and found some new functionalities that are very useful:
1) Copy and paste SCHEMA (picture below).
2) Export style as SDL file.
3) Measure a line or an area and create a new layer with the value (picture below).
The new version is more clear and all the extensions are better integrated. I add the old raster plugin because it give the possibility to cut a photomosaic using a square selection (Fence) and to save the result as tif/tfw. The picture below show the procedure.
