The getResourceAsStream() method is implemented by the class loader, and
if iPlanet is using their own class loader for servlets (likely) and have
not implemented this method the same way as the default class loader, you
may have a problem. One way around this problem is to make sure the pool
classes are not loaded by their special class loader, but by the primordial
class loader. Typically that's what happens if you place the classes in the
class path used by the servlet container itself as opposed to the directories
used for storing servlet classes (see the iPlanet docs for details).
As an alternative, you can use a servlet to initialize the connection pool, and
specify an init parameter for this servlet that contains the absolute path for
the properties file.
