| * <p> |
| * either ROOT.WAR or / denotes root context |
| * <p> |
| * anything of form FOO.?AR (ending .?AR) is copied with that name (unless copying not necessary) |
| * and is expected to be served from /FOO |
| * <p> |
| * anything of form /FOO (with leading slash) is expected to be served from /FOO |
| * (and is copied as FOO.WAR) |
| * <p> |
| * anything of form FOO (without a dot) is expected to be served from /FOO |
| * (and is copied as FOO.WAR) |
| * <p> |
| * otherwise <i>please note</i> behaviour may vary on different appservers; |
| * e.g. FOO.FOO would probably be ignored on appservers which expect a file copied across (usually), |
| * but served as /FOO.FOO on systems that take a deployment context. |
| * <p> |
| * See {@link FileNameToContextMappingTest} for definitive examples! |
| * |
| * @param url where to get the war, as a URL, either classpath://xxx or file:///home/xxx or http(s)... |
| * @param targetName where to tell the server to serve the WAR, see above |
