Are you sure that you've correctly downloaded the JAR file? First, what is the size of the file? Mine is 7Mo. answered 03 Feb '12, 13:49  NicolasDumoulin edited 03 Feb '12, 13:50 |
Have you tried downloading the latest jar file again, perhaps after deleting the copy you downloaded already? I'm using 4878 on Windows 7 without any problems (though give it a bit more memory -Xmx1500m). Having said that I only seem to be on update 22, so will update and check again. Edit: I've updated to update 30 and still all is OK. What version did you upgrade from? A few stable releases ago I had problems starting JOSM (I don't think it was a corrupt jar message though) and had to remove my settings files and start configuring it from scratch again. I renamed the folder to just to perform the test answered 03 Feb '12, 09:45  EdLoach ♦ edited 03 Feb '12, 09:51 I have downloaded the latest jarfiles a couple of times, i am thinking this might be a Java issue as i have gone back in the josm archives and downloaded previous versions that should have worked from last year and i am still getting the same problem. I have also removed my settings files which has not changed anything (03 Feb '12, 10:05) samlarsen1 Have you tried then uninstalling Java and redownloading it? (As I did to update from 22 to 30). (03 Feb '12, 11:31) EdLoach ♦ I've uninstalled & reinstalled java and still have the same problem. It must be a problem with my system, i will try to run some other executable jars.

I have downloaded from: http://josm.openstreetmap.de/josm-tested.jar Filesize is 2,441Kb Version 4878
Ok, so something is wrong with your download. Which web browser are you still using? Try another one: firefox, IE, chrome, …
I was using a python script which checks the latest online version before opening JOSM & downloads a new one if the version number has increased.
It has worked successfully for at least a year, i don't know why it is now not working. I'll try to fix the python script or just download manually in the future.
Thanks for your help
