You need to perform this task only if you are setting up prerequisite products for PKI Services for the first time, or if you are implementing the PKI Services Web application using Java™ server pages (JSPs) for the first time.

If you implement the PKI Services Web application using Java server pages (JSPs), you must install Websphere Application Server 6.1 or higher and configure an SSL configuration that uses client authentication. For more information, see Implementing the Web application using Java server pages and the online information center for your release of Websphere Application Server at http://www.ibm.com/software/webservers/appserv/was/library/.

You do not need to install Websphere Application Server if you implement the PKI Services Web application using REXX CGI execs.
