No political boundaries

[sebastian_b]

Hello,
today I noticed that in my application the political boundaries are not displayed anymore. As I haven't changed the code in the past days, I don't know what causes the problem. Any hints?

Bye,
Sebastian

Network problem probably.

Do you have the layer listed?
new CountryBoundariesLayer(),
Look at JavaOneDemoA.java that sets it to
wwd.setModel(new BasicModel());
this does not use the CountryBoundariesLayer
Look at JavaOneDemoB.java which does not list the CountryBoundariesLayer
Not knowing how your app is set up it is hard to tell why it is not showing up if it was before. If your app is set up similar to JavaOneDemoB.java then just add the line:
new CountryBoundariesLayer(),

edit: If it was a network problem it seems the boundaries that were downloaded when your app was working before should be in your cache and at least those should show up.

Network problems on my side? If that's the case, then I shouldn't receive any data - right? But beside the political boundaries everything else works fine (as far as I know).

Here's there code that used to work in the past:

myCountryBoundariesLayer = new CountryBoundariesLayer();
myCountryBoundariesLayer.setEnabled(true );
insertBeforeCompass(getWwd(), myCountryBoundariesLayer);

@nlneilson:
I add the line "new CountryBoundariesLayer()" in JavaOneDemoB but unfortunately without success.
One possible reason is, that I'm working on another computer now (the harddisk in my laptop crashed). But everything else works fine.

Open JavaOneDemoB.java and add the line:
new CountryBoundariesLayer(),
If this shows the Boundaries then you will need to debug you app to see why yours is not showing the layer.
Does the check box for turning the layer off and on show up?

edit: I posted this before your last post showed up.
The WWJ SDK DemoB with the line added should work. You may need to re-install on the new hard drive.

If I understand the class CountryBoundariesLayer correct, then the application tries to receive the data from an URL like this: http://worldwind21.arc.nasa.gov/geos...ansparent=true

If I copy this link in my browser I got an error message (can't connect to the server). Maybe that's the problem?

CU,
Sebastian

He is probably right there is a problem with the server at worldwind21.arc.nasa.gov.
I get this error:
can't establish a connection to the server at worldwind21.arc.nasa.gov.

worldwind25.arc.nasa.gov that has many of the other tiles is OK.

Look in the cache on the computer you are now using, there are probably no files in the Boundaries so none will display until the server for worldwind21.arc.nasa.gov. is working so the tiles can be downloaded.

Any information when the server will be back online?

Change the server called to worldwind25. worldwind21 is now out of commission, and will likely remain so.
