Sun Java System Application Server Enterprise Edition 8.2 Release Notes


If you install the Load Balancing plugin against an installation of the Application Server that already has a Load Balancer plugin installed (for example, from 7.1EE), then the 8.2EE plugin will silently replace any existing Load Balancer, even if you have created a new server instance in which to run the plugin.

The plugin files are installed by default under the install_dir/plugins/lbplugin directory, which means that only one version of a plugin can be used with any one Application Server installation. Note that the console installer does display a message indicating that an uninstall is being performed, but this message can sometimes be easy to miss.
