Chapter 4, Migrating and Upgrading 79
Upgrading From iPlanet Web Server 4.0
Java Servlets
iPlanet Web Server now recognizes servlets in a package without requiring you
to register each servlet in the package and map the virtual paths. For more
information, see the Programmer’s Guide to Servlets in iPlanet Web Server.
Java Configuration Files
When you install the Java subcomponent, the configuration files that are
installed include a set of files that end in .default (for example,
rules.properties.default). These files contain the default values for the
Java configuration files. During migration, the Java configuration files are not
changed from the previous version. If you want to update the old files to the
new settings, refer to the .default files. You can also refer to the .default
files in the future if you want to revert to the iPlanet Web Server 4.1 default
settings.
WAI Subcomponent and Express Installation
If you installed the WAI subcomponent with your iPlanet Web Server 4.0, do
not use Express installation when you upgrade to iPlanet Web Server 4.1. Your
WAI files will not be updated, because the Express installation doesn’t install
WAI.
