MORE INFORMATION

The following text is a copy of the missing section:

DEVELOPING JAVA APPLETS/APPLICATIONS USING THE NEW JAVA VIRTUAL MACHINE

The new Java virtual machine in this release of Internet Explorer 4.0 uses a different system of organization for packaging classes. Earlier virtual machines used Java classes packaged in an uncompressed zip archive. This zip archive could also be read by tools and compilers such as Visual J++ 1.1. Because the new virtual machine uses a package manager to organize class files, this zip archive of classes is not available by default, and no zip files will be present for compilers and other tools to use.

For developers who require a zip archive for their tools to work, the tool Clspack is provided. Clspack (available from the Windows directory in Windows 95 or the Windows\System32 directory in Windows NT) allows you to take packages that are currently installed in the package manager, and write their contents into a ZIP file that tools can use.

Running Clspack -auto creates a single Classes.zip file in the %WINDIR%\Java\Classes directory that contains all classes stored in the package manager. By default, the Microsoft Java compiler looks in this location for classes, so there is no need to set the CLASSPATH environment variable.

For other compilers that do not check this location by default, you need to set the CLASSPATH environment variable as follows before running the compiler:

     set CLASSPATH=%WINDIR%\Java\Classes\Classes.zip

For more information about CLASSPATH and other development issues, see the Microsoft Web site at http://www.microsoft.com/java/.
