Java Blender Guide

What is Java Blender?

Java Blender is an iAppli compression tool. Using single-character identifiers and using as few classes as possible, code size can be considerably reduced, which is important given limits on iAppli size. The management [of this kind of optimization] can be automated by using Java Blender. Java Blender makes it easier to write "normal Java" in iAppli even for programs that couldn't load without this sort of compression.

How to use Java Blender

First, get your iAppli perfect. I.e., prepare a proper JAR and JAM file. Then, using Java Blender, put the JAM file in a designated place. [???] After that, push the "compress" ("圧縮") button, and with the image going "bakabaka" [like I do all the time - transl.] the program will get compressed. At this point, the original JAR and JAM files will be overwritten -- so be careful now.

Concerning differences in compressability

With compressibility set to "Strong" ("強"), you can make iAppli quite small. However, this setting can also increase the memory requirement.

How to get Java Blender

The installer is freely distributed.

Installer Java Blender version 1.00alpha for Windows 95, 98, 2000. (3MB)
Installer Java Blender version 1.01alpha for Windows 95, 98, 2000. (3MB)
Points of difference: META-INF not included in resulting jar file.
Installer Java Blender version 1.02alpha for Windows 95, 98, 2000. (3MB)
Points of difference: can't correctly recognize when there are [already] classes of the same name as the abbreviated forms [generated] (e.g., "D", "Z", "I", etc.). Also, the date format changed from "%2d" to "%02d".
Installer Java Blender version 1.03alpha for Windows 95, 98, 2000. (3MB)
Points of difference: Name-shortening algorithm revised

License terms

For those interested in the compression algorithm

Look here for the home page for my literature on the subject. I'll be releasing the source code soon.

Caveats

This software is not guaranteed. Cocoa bears no responsibility for the results of anything produced by Java Blender.
Make sure it's OK to delete everything in the installation directory when you do "uninstall".
iAppli that rely on Class.forName will no longer work correctly.
