Using Eclipse 3.4 or later it is possible to configure the help plugins to be deployed as a web archive (war file) which will act as a fully functioning information center.

git clone https://git.eclipse.org/r/platform/eclipse.platform.ua.git
git clone -q --depth 1 https://git.eclipse.org/r/platform/eclipse.platform.releng.aggregator && mvn install -N -f eclipse.platform.releng.aggregator/eclipse-platform-parent && mvn install -N -f eclipse.platform.releng.aggregator/eclipse.platform.releng.prereqs.sdk

You should see the message "Servlet delegate registered - org.eclipse.equinox.http.servlet.HttpServiceServlet". You may instead see the message "Servlet delegate not registered.". This indicates that bundle activator from bundle org.eclipse.equinox.http.servletbridge was not started or that it accesses a different instance of class org.eclipse.equinox.servletbridge.BridgeServlet.
For all available framework control endpoints refer to org.eclipse.equinox.servletbridge.BridgeServlet.serviceFrameworkControls(HttpServletRequest, HttpServletResponse).
