One way to do this is to override BaseEngine.createVisit to construct 
your Visit passing Global (from getGlobal()) to it's constructor or 
setter.  Be sure to set your custom engine class in your .application 
file.

While there are solutions to this problem (like Erik's), I'd
like to suggest that you store data in your Visit object only.
If you need processing logic, you should put it somewhere
else (eg, in Global) and pass the data contained in the Visit 
object to it:

class Global {
  void someProcessing(User user) {
    ...
  }
}

Call it like:

void someListener(IRequestCycle cycle) {
  ((Global)getGlobal()).someProcessing(((Visit)getVisit()).getUser());
}
