Bug JOSM

[SiiG]

Hello,

Under Windows 11 Professional, I've been unable to launch JOSM for a few days.
The following error message is displayed (see attached file):

net.sourceforge.jnlp.LaunchException: Fatal: Read Error: Could not read or parse the JNLP file at 'file:/F:/TECHNIQUE/softs/Josm/josm.jnlp'. You can try to download this file manually and send it as bug report to IcedTea-Web team.

Thank you for your help,

I'd assume that you deleted the file you used to start JOSM. Use one of the methods described in the wiki to start josm or redownload the JNLP and replace it at the filename given in the error message.

ok thanks. I downloaded the latest version of the jnlp file and JOSM is now working.
