Issues with Open Street Map: unknown error message

[Alexandra McInturf]

Hello! 

I’m having some issues generating a map using OSM…I’ve been trying to plot current data onto this map of the SF Bay, which my advisor has been able to do successfully on his computer but I have not. My code is attached, although the current files are too big for me to send here. I’ve also pasted the error message. If anyone has any idea what this means, I would appreciate it! 

java.lang.NullPointerException

at edu.cens.spatial.RTileController.getTileValues(RTileController.java:109)

at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

Error in osmtile(x%%nX, y, zoom, type) : 

  could not obtain tile: 653 1581 12

Thanks!

What package are you using that it requires Java?
Just post the part of your code that makes the OSM tile request and
plot. We don't need to see much else.

Thanks,
