Find the filesystem roots using the appropriate method in that class, use one of the listXXX methods to ... |
8. Search for a file in a drive coderanch.comWell, I was presuming you already had some code to go through directories of files. Perhaps using the listFiles method of the File class. In that case I was suggesting you use the file size as the main comparison method. IMHO timestamps are not reliable enough since (esp in Windows) they sometimes seem to change a lot. But the matching method ... |

Perhaps you're trying to use Apache httpd as a front-end to Glassfish? |
