jarDirectoriesAndFiles

public static byte[] jarDirectoriesAndFiles(String[] directoriesAndFiles,
                                            String manifestVerion,
                                            String mainClass,
                                            String jarInternalClasspath,
                                            CRC32 crc)
                                     throws IOException

Create a jar file that contains all the directory listed in directories parameter.

Parameters:

directoriesAndFiles - the list of directories and files to be jarred.

manifestVerion - the version of the jar manifest (can be null).

mainClass - the main class of the jar (can be null).

jarInternalClasspath - the class-path of the jar (can be null).

crc - the CRC32 of all jar entries. Can be null if no crc is needed.

Returns:

the jar file as a byte[].

Throws:

IOException - if the jar file cannot be created.

                     throws IOException

Jar directory content in the given output stream

Parameters:

zos - the output stream in which to store the jarred directory

directoriesAndFiles - a list of directories and files to be jarred

Throws:

IOException - if a jar entry cannot be created.

jar

public static void jar(String[] directoriesAndFiles,
                       File dest,

dest - the jar destination file that will contains the jarred version of the first argument.

manifestVerion - the version of the jar manifest (can be null).

mainClass - the main class of the jar (can be null).

jarInternalClasspath - the class-path of the jar (can be null).

crc - the CRC32 of all ajr entries. Can be null if no crc is needed.

Throws:

IOException - if the zip file cannot be created.

unjar

public static void unjar(JarFile jarFile,
