              software that is peaceful, you must use it at your own risk.

              Please report bugs to 100435,455@CompuServe.COM. Also, feel

[ --- What is DeJAVA? --- ]

DeJAVA is a utility that allows JAVA developers to disassemble byte code files.
It is a replacement for the JAVAP utility that ships with Suns JDK. Like JAVAP
it is a 32-Bit console application which does not include a graphical user 
interface. It is designed to run under Microsoft Windows 95 or Microsoft 
Windows NT.

Main features include:

  - Full support of debug information including:
    - Java source text in disassembly listing
    - Local variables
  - All references are resolved (no 'mangled' names!)
  - Static initializers
  - Nicely formatted output

DeJAVA was initially developed for internal use at PFP, while we develop our 
upcoming JAVA compiler technology. If you would like more information on that
subject, or if you want licensing information, or if you want to be included 
in our mailing list, please send an eMail to:

        100435,455@CompuServe.COM

[ --- How do I use DeJAVA? --- ]

The original distribution archive contains some sample files which demonstrate
the usage of DeJAVA:

HelloWorldApp.java	A simple Java source file file
HelloWorldApp.class     A compiled version of HelloWorldApp.java
HelloWorldApp.dis       DeJAVAs disassembly of HelloWorldApp.java (ASCII text)

d.bat			A simple batch file to disassemble HelloWorld.java
c.bat                   A simple batch file to compile HelloWorld.java

For best results, compile your JAVA source files with debug informations (-g) 
and include the source file in the same directory as the byte code file.


[ --- Revision history --- ]

BETA 1.02

    * First public review of DeJAVA.
    * Fixed LOOKUPSWITCH/TABLESWITCH bug.

    
[ --- Known Limitations --- ]

None.


[ --- What if I find a bug? --- ]

The best way to test an application is to give it to a lot of people to try.
Although the program seems to work fine as far as we've tested, there may be
some conditions under which it might fail completely!

Since this program is still in development, we expect that bugs do exists. If
you discover a problem with the application, please report it to:

        100435,455@CompuServe.COM

To assist us in finding the source of your problem, we need information on what
input DeJAVA was not able to handle properly. The best for us to determine what 
happened is for you to send us the smallest possible offending section of code 
(we do NOT want the whole project!!!).

We realize that the portion of code in question may be confidential in nature.
If for this (or another) reason you cannot mail us the offending code section,
please describe what types of constructs you used in your source where the 
error might have happened.


Thanks again for downloading DeJAVA!
