Hi,
when I write unit tests for JOSM I also set
Main.proj = new Epsg4326(); // if null nearly every construction of a
Node
// fails
Or let josm.home point to a directory with a preferences file, i.e.
System.setProperty("josm.home", "/my/josm/home");
Then I use
Main.pref.init(false); // SIC: not true, otherwise whatever prefereces
you have
// are deleted

PS: the structure of JOSM would benefit from something called "dependency
injection". Just my two cents.

Betreff: [josm-dev] Integrating the map panel on another application
Hi,
I am trying to use the panel map integrated in JOSM (without the menus and
the
toolbars) on another Java Application, where I want to load a couple of osm
files.
I have found the MapViewer and the MapFrame classes, but when I try to
integrate them on my JFrame, it crashes. I know that there are some
preferences loaded on the Main class of JOSM and I am trying to replicate
whatever the Main loads so I can use the map panel on my project.
So far I have found this:
Main.platform = new PlatformHookUnixoid();
Main.platform.preStartupHook();
Main.pref.init(true);
which I think are necessary to load the map.
After that I try:
map = new MapView();
frame.add(map);
and it works, showing me an empty map (black), although it says that the
projection could not be read from the preferences and prints an exception:
java.lang.ClassNotFoundException:

When I try to load an osm layer from a file:
Layer layer = new OsmDataLayer(new DataSet(), "prueba", new
File(""));
map.addLayer(layer);
It simply crashes, throwing this:
Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException

I am wondering if someone can help me pointing me how can I separate the map
panel from the rest of the application. If it is possible. I just need a map
that shows osm files, nothing more.
Thanks for your help :)
