Method Detail

loadProperties

public static void loadProperties(java.util.Properties props,
                                  java.lang.String fileName)

canSave

public static boolean canSave()

saveProperties

public static void saveProperties(java.util.Properties props,
                                  java.lang.String fileName)

openFile

public static java.io.InputStream openFile(java.lang.String fileName)

Opens a single file. For the exact rules on where this method looks, see scanForFiles(String, boolean).

openFileForWriting

public static java.io.OutputStream openFileForWriting(java.lang.String fileName,
                                                      boolean createIfNew)

Opens a single file for writing. For the exact rules on where this method looks, see scanForFiles(String, boolean). It may also create the required file if not found, if you request it to do so.

scanForFiles

public static java.util.List scanForFiles(java.lang.String fileNameOrExtension,
                                          boolean exactMatch)

Scans for files that match exactly or have a specified extension. If the application is running in a web container the method scans:

1. WEB-INF/classes
2. WEB-INF/lib (all jars)

If the application is running outside a web container (eg. unit testing) the method scans: *

1. all jars on the classpath
2. all folders on the classpath

Returns a list of URLs pointing to the matching files.

getAllJarFileURLs

scanForFilesInJars

                                                boolean exactMatch)

scanForFilesInFolder
