An Eclipse based WAR product is a WAR archive built with the Eclipse platform. A WAR product will be packaged and delivered as one .war archive file.
WAR Products include all the code and plug-ins needed to run the WAR on a Servlet-Container. A WAR product typically contains all bundles that are needed to run Equinox on the server side.
Once deployed, a user accesses the application with the URL specified in the containing web.xml file.
PDE provides a WAR product configuration file and associated editor to make it easy to create WAR products in the correct format.
