JarHack

public JarHack()

substHecl

public static void substHecl(java.io.InputStream infile,
                             java.lang.String outfile,
                             java.lang.String newname,
                             java.lang.String iconname,
                             java.lang.String scriptfile)
                      throws java.io.IOException

The substHecl method takes the filenames of two .jar's - one as input, the second as output, in addition to the name of the application. Where it counts, the old name (Hecl, usually) is overridden with the new name, and the new .jar file is written to the specified outfile. Via the iconname argument it is also possible to specify a new icon file to use.

Parameters:

infile - a FileInputStream value

outfile - a String value

newname - a String value

iconname - a String value

Throws:

java.io.IOException - if an error occurs

createJadForJar

public static void createJadForJar(java.lang.String jarfile,
                                   java.lang.String appname)
                            throws java.io.IOException

The createJadForJar method calls createJadForJar with a url created from the application's name.

Parameters:

jarfile - a String value

appname - a String value

Throws:

java.io.IOException - if an error occurs

createJadForJar

public static void createJadForJar(java.lang.String jarfile,
                                   java.lang.String appname,
                                   java.lang.String url)
                            throws java.io.IOException

The createJadForJar method creates a new .jad file that matches the .jar file passed to it. appname is the name of the new application.

Parameters:

jarfile - a String value

appname - a String value

url - a String value

Throws:

java.io.IOException - if an error occurs

main

public static void main(java.lang.String[] args)
                 throws org.apache.commons.cli.ParseException

main implements a command line version of JarHack that takes five arguments: 1. The original 'template' .jar file to use. 2. The destination directory where you want to create your new application. 3. The name of your new application as it will appear in the MIDlet. 4. The name of the Hecl script you want to use instead of the script.hcl that is included in the 'source' .jar file. 5. The URL where your jar file will reside.

Parameters:

args - a String[] value

Throws:

org.apache.commons.cli.ParseException
