[OSM-talk] Running JOSM

[Immanuel Scholz]

Hi,

I'm answer to an rather old post from May, 12th.

As said before, JOSM does not run with the Java implementation from GNU
together with Classpath, which is preinstalled for many Linux
distributions for today.

That looks strange. How do you tried to start the it and see this message?
If you did something like entering into a command shell:

java josm-latest.jar

then replace it with

java -jar josm-latest.jar

;-). On any recently intstalled java binary from SUN you should also be
able to just double click on the jar file.

If you have 10.3, then you have not the correct java version (at least 1.5
required). If you have 10.4, then maybe no java is installed for your OS
version at all?


Some explanation on how to start and how to obtain the correct Java
version (especally for Linux) is at
