Search for the old "MS SDK for Java 4.0" somewhere (no, you can't find it at Microsoft's site).
There are two files that you have to get: sdkdocs40.exe (a file with 10,895,496 bytes) and SDKJava40.exe (a file with 20,222,928 bytes).
Use the embedded jvc compiler to recompile your program. Beware: try not to rely too much in jvc. Use it only for discover that you're using methods not implemented in JDK 1.1.8, but don't use it for deploying your app.
You'll discover that you'll have to rewrite large portions of your program, and even change your program specifications to deal with the reduced functionality of the old MS JVM (for instance, say that you'll need to change the 'modified date' of a file.
In JDK >= 1.2 there's the method File.setModified(); in MS JVM you'll need to use some com.ms.wfc function.
