Hi, That is not a problem at all for OpenJUMP because it does not even read .prj file. OpenJUMP takes the coordinates as they are and places the features on the map. Shapes can be edited and saved and projection remains the same as it was. And if you create a new layer and save that as shapefile OpenJUMP writes only the compulsory .shp, .shx and .dbf parts. It is up to user to know what coordinate system was used for creating the data. Also the native JUMP JML format does not have any place to store the projection info. For using the coordinate transformation plugin user needs to somehow know the source SRID and feed it manually. PostGIS layers seem to be exception and for those the native SRID is automatically known.
That OpenJUMP is happy without .prj does not mean that OpenJUMP user is also happy. Is your tool trying to guess the projection somehow like in this web service http://projfinder.com/? -Jukka Rahkonen- manf...@egger-gis.at wrote: Thank you for your fast response. What about shapefiles missing a .prj. Do you have a solution for this classic projection problems? This is what my tool deals with.

It is activated if layer property plugin is selected ( under layer or raster context menu ). I added on OJ nightly build a couple of months ago ). It doesn't use geotools or similar as the main aim was only proj file recognition.
