Validate the accessibility of the non-directory file identified by name. The file must exist, must not be a directory, and must be readable. If any check fails, an error message is returned. If all checks are successful, null is returned.

Parameters:
name - the file name
desc - a short descriptive string which describes the file, suitable for inclusion in the error message
Returns:
and error message, or null if all checks pass

checkURL

public static String checkURL(URL url,
                              String desc)
Check the accessibility of the given URL. If the url is a file: url, the usual file access checks are performed. For any other url a stream is opened, and a non-exceptional return is considered a success.

Parameters:
url - the URL to check
desc - a description of the source of the url
Returns:
an error message, or null if the access check passes

checkSystemPropertyFile

public static String checkSystemPropertyFile(String prop,
                                             String desc)

The file identified by the value must exist, must not be a directory, and must be readable. If any check fails, an error message is returned. If all checks are successful, null is returned.

Parameters:
prop - name of a system property whose value must be a file name
desc - a short descriptive string which describes the file, suitable for inclusion in the error message
Returns:
an error message, or null if all checks pass

getResourceBundle

public static ResourceBundle getResourceBundle(Class clazz)
Get the resource bundle associated with class clazz. The resource bundle name is constructed by the class name to lower case and inserting .resources in front of the name. Thus, if clazz.getName() returned a.b.Foo then the associated resource bundle name would be a.b.resources.foo. If no resource bundle having the associated name is found, a stack trace is printed and null is returned. The resource bundle is loaded using the class loader for the given class, and is cached so that the search is performed only once.

Parameters:
clazz - the class for which to obtain a resource bundle
Returns:
the resource bundle
