Class Resource

java.lang.Object

ucar.unidata.util.Resource

public class Resource
extends java.lang.Object

Cover for fetching files using Class.getResource(). If the application is started from a jar file, then it looks in there. If the application is started from a class file, then it looks in the disk file heirarchy, using directories in the classpath as root(s). 1. Filenames. use "/" as path seperator when embedded in a string. This works on both Windows and Unix. 2. Filepath. Use a resourcePath starting with a forward slash. getResource() then searches relative to the classpath. otherwise it will search reletive to ucar.unidata.util, which is probably not what you want.
