RE: [OpenMap Users] Displaying CADRG

I too am having an RPF problem.

I've successfully created my A.TOC file and placed it inside my
c:/map/RPF dir as specified. However when I start my RpfLayer and
openmap I get the following error:

RpfLayer: Need RPF directory paths.

*** ERROR ***
RPF|RpfLayer.prepare(): null frame provider - either no RPF paths were
set, or n
o frame provider was assigned. The RpfLayer has no way to get RPF data.

Here is how I create my RpfLayer. Any ideas? Thanks.

    Properties p = new Properties();

        RpfLayer rpfLayer = new RpfLayer();
