The requirements to use either BEA WebLogic Server or IBM WebSphere Application Server as the web container include:
WebLogic Server and WebSphere Application Server are not part of the Sun Java Enterprise System (Java ES). Therefore, you must obtain the web container software from BEA or IBM and then install and configure them independently of the Java ES installer.
You should be familiar with administration tasks for the web container, including configuring, starting, and stopping an instance.
When you configure Access Manager by running the amconfig script (or amconfig.bat on Windows systems), the web container must be installed, configured, and running.
Access Manager requires Sun Java System Directory Server. Either install a new Directory Server using the Java ES installer or specify an existing Directory Server.
