Danny,
We deploy our OpemMap based application using Java Web Start.
We use the MapBean (not the OpenMap app) within our application, several OpenMap layers, plus a slew of custom layers. Due to the size of our CADRG data sets (some >1GB) we elected to have users "install" the data sets locally. We initialize the RPFLayer with the locations of the data sets by canvasing predefined locations. All RPF data sets are included allowing multiple scales (ONC, TPF, etc) to be available for rendering.
We haven't had the time yet, but we have thought of extending the RPF layer to acquire the RPF data set from an http server. The data would be cached locally. Tiles, of course, would be downloaded on an as needed basis avoiding the need to download the complete data set.But once downloaded, the layer would enjoy the benefit of local access to the data sets.
Cheers,
David

Subject: [OpenMap Users] Loading OpenMap with Java Web Start
Has anyone been able to load openMap successfully using Java Web Start?
I know it can be done since one of the demos for OpenMap uses Web Start,
but I am having problems doing it in my application. The problem is
that I'm trying to find my "a.toc" file by searching through directories
in my jar, but I am having problems loading the resources as a File
object in my code and seeing if it is a directory and listing the files
underneath it. I know there's been some discussion regarding
instantiating a File object from jar resources, and I hope i'm not
rehashing old material. I really need help on this though. Thanks..
