The Portal Server software requires the following stack components:
Sun Java System Directory Server 6
Sun Java System Access Manager 7 installed in legacy mode.
Portal Server requires Access Manager, Directory Server, and a web container for its installation and configuration. If you are performing a fresh installation, Access Manager and Directory Server do not have to be pre-installed. Access Manager, Directory Server, and Portal Server can all be installed at the same time. If you have Access Manager and Directory Server installed already, point the portal installation and configuration to the existing Directory Server and Access Manager servers.
Sun Java System Web Server 7 or Sun Java System Application Server 8.2.
Sun Java System Portal Server 7.1 software does not support Sun Java System Access Manager 7 installed in realm mode. Access Manager must be installed in legacy mode before installing Portal Server 7.1 software. By default, Java ES 5 installer configures Access Manager in legacy mode in Configure Automatically During Installation mode.
For detailed instructions for installing the stack components, see the Sun Java Enterprise System 5 Installation Reference for UNIX.
