WebSphere Application Server (optional)

If you implement the PKI Services web application using Java™Server pages (JSPs), you must use WebSphere Application Server 6.1 or higher. An application server is a Java virtual machine (JVM) running user applications. WebSphere Application Server provides application servers that handle web application requests.

If you implement the PKI Services web application using REXX CGI execs, WebSphere Application Server is not required.
