Table 1–1 Preinstallation Checklist


Task	Instructions and Helpful Information
1. Plan your Java ES installation.	Refer to the Sun Java Enterprise System 5 Installation Planning Guide.
2. Determine that a valid version of Java 2 Standard Edition (J2SE^TM) for Java ES is installed on your machine.	If the installer does not find J2SE 1.5_09 or later on the machine, the installer installs J2SE in the `C:\Java` directory.
3. Determine whether any release noted issues affect your installation.	Before performing any of the procedures described in the Installation Guide, you should read the Sun Java Enterprise System 5 Release Notes for Microsoft Windows. These notes contain installation issues that might pertain to your deployment.
4. Verify that system requirements are met.	Refer to Determining Whether Your Hosts Are Ready.
5. Determine whether an installation sequence example can be used.	Refer to Chapter 2, Example Installation Sequences.
6. If you are installing Java ES components that depend on servers or services that are already installed, ensure that the existing servers and services are accessible.	For example, if you are installing a Portal Server Secure Remote Access subcomponent, the Secure Remote Access core must be running and accessible.
7. Ensure that the drive you are using is an NTFS drive.	To install Java ES on a Windows operating system, the installation drive should be an NTFS drive.
8. Stop firewall services.	If there are any firewall running on your host system, disable and stop firewall services and restart you host system. Make sure that the firewall services are disabled after restart. Once the installation of Java ES 5 is complete, you can restart these stopped firewall services.
