Of course with each new release of WTP the process describe for WTP 0.7 is less and less successfull. But this comes with no surprise, as those were undocumented and temporary features. For those who wonders, the assembled webapp now resides under your workspace directory in .metadata/.plugins/org.eclipse.wst.server.core/tmpX where X is the number of your server starting at 0. Using this tmp folder clearly indicate that nobody should rely on the files at this location, as they will be regenrated with the build process. Those tmp folders also allows eclipse to build a separate assembly specific to each server, which make a lot more sense than the .deployables directory which was shared amongts all server instances. If you need to explicitely reference this directory, you should probably review your build process (but you are already using Maven, right?).
