The six blind men* who attempted to describe the elephant eventually described it only from their perspectives - the parts and not the whole. The same malady can be found lurking in one of the problems that faces many organizations that have adopted J2EE as their platform of choice: the migration of these applications between J2EE application servers - be it vendors or versions.
