From the docs - "If you choose not to install Oracle HTTP Server, for example in a development environment, EPM System Installer installs an embedded WebLogic HTTP Server as part of Foundation Services that acts as a proxy server. In a production environment, Oracle recommends that you install Oracle HTTP Server for use with WebLogic. If you are deploying to WebSphere, you must use IBM HTTP Server."
