VJ++ Upgrade to SDK 1.1

How to Upgrade VJ++ to JDK 1.1

Step	Notes	Files
1 - Upgrading the compiler	Required
-------( a ) Back up your old compiler (jvc.exe) from the "SharedIDE\bin" subdirectory of your Visual Studio Installation	Try C:\ProgramFiles\DevStudio\SharedIDE\bin
-------( b ) Download the new version of the java compiler	Compiler.zip ~ 131KB	compiler.zip
-------( c ) Extract the files from compiler.zip into the "SharedIDE\bin" subdirectory of your Visual Studio Installation (the same directory jvc.exe was in)	This will overwrite your old jvc.exe. If you did not make a backup in step 1, you may wish to do so now...
-------( d ) You may check the compiler version either by running jvc.exe, or viewing the file properties for jvc.exe, selecting the "Version" tab, and clicking on "Product Version".	The version should be 1.02.4337
2 - Installing the new Java Virtual Machine	If you have installed IE 4.0 you may skip this step
-------( a ) Download the updated Java Virtual Machine (VM)	msjavx86.exe ~ 4.6MB	msjavx86.exe
-------( b ) Run msjavx86.exe to install the Java VM	Users of IE 3.0 may safely ignore the warnings about IE 3.01 and Authenticode 2.0
-------( c ) You may verify your installation by compiling and running this sample applet/application	Foo.java ~ 1KB This may be run as an applet or as a stand-alone application. The applet/application uses the java.math.BigInteger class introduced in Java 1.1, and should display the number 9999.	Foo.java

Notes

Many methods from Java 1.0 have been deprecated in Java 1.1. What this means is that the authors of those methods wish to phase out their usage in favor of new, improved methods. A great number of methods in the java.awt package have been deprecated, and you will probably see a good deal of warnings about this. The warnings will tell you which methods have been deprecated.
The book Java in a Nutshell, published by O'Reilly, is an excellent source for information, and gives a good description of the changes from Java 1.0 to Java 1.1. In addition, you can find material on Sun's Java web site.
As long as you are not using any new functionality of Java 1.1, you can compile your Java 1.0 code with the new compiler and run it under any environment that supports Java 1.0 (Netscape Navigator 3.x, Internet Explorer 3.x, etc.)
