ServletExec 4.1 Installation Guide 68

6. ServletExec/AS: Application Server

(UNIX/Linux)

Installing the UNIX web server adapters for Netscape Enterprise Server,

iPlanet Web Server, and Apache HTTP Server

he ServletExec Application Server (ServletExec/AS) is a standalone web

application server that hosts Java Servlets and JavaServer Pages (JSP).

ServletExec/AS does not contain a built-in HTTP (web) server. Therefore, it must

be used in conjunction with Netscape Enterprise Server (NES), iPlanet Web Server

(iWS), or Apache HTTP Server. Web server adapters for these web servers are included

in the ServletExec/AS installer.

The ServletExec/AS for UNIX® installer is named

ServletExec_AS_41.sh. If you

haven’t already done so, you can download the installer from:

http://www.newatlanta.com/downloads/index.jsp

This chapter contains important information that will allow you to verify your installation

of ServletExec/AS for UNIX. It will also be useful should you decide to uninstall

ServletExec/AS and need to make sure you’ve completely removed all installed

components.

6.1 Upgrading From a Previous Version

You can upgrade to ServletExec 4.1 from all previous versions except versions 3.0C or

3.0E. If you have either of these versions installed, you will need to completely uninstall

that version and do a clean installation of ServletExec 4.1.

ServletExec/AS 3.0 and later replaces the ServletExec/Apache and ServletExec/WAI

implementations of ServletExec 2.2 and earlier. However, the ServletExec/AS

configuration files are slightly different from those for ServletExec/Apache and

ServletExec/WAI. Therefore, it is not possible to automatically upgrade from

ServletExec/Apache or ServletExec/WAI to ServletExec/AS. Instead, you must do a

clean install of ServletExec/AS and manually re-enter your configuration data using the

ServletExec Admin UI.
