1. INTRODUCTION
ServletExec 4.1 Installation Guide 2
If you’re using Microsoft IIS or NES/iWS and you aren’t sure whether the Servlet Engine
or Application Server configuration is best for you, we recommend starting with the
Servlet Engine version of ServletExec (ServletExec/ISAPI or ServletExec/NSAPI). If
you’re using Apache, only the ServletExec/AS version is currently available.
ServletExec Servlet Engine ServletExec Application Server
• Runs within the web server process
(loaded as a Windows DLL or
UNIX .so)
• Runs as a standalone process,
separate from the web server
• Best performance • Greatest architectural flexibility
• Easiest to install and configure • Enhanced safety (process isolation)
• Single Java VM per web server • Multiple Java VMs per web server
• ServletExec starts/stops
automatically when the web server
starts/stops
• ServletExec starts/stops
independently of the web server
Table 1. ServletExec Configurations
There are separate ServletExec installers based on your web server, operating system, and
choice of Servlet Engine or Application Server product. Make sure you’ve downloaded
the correct installer, and then refer to the appropriate chapter of this manual for detailed
installation instructions.
