How to know regions in a RegionServer?

How could I know with Java which Regions are served for each RegionServer?
I want to execute an parallel scan, one thread for each regionServer
because I think that's better than one for region, or is it not??

For 0.98, please take a look at this method in HTable:

  public NavigableMap<HRegionInfo, ServerName> getRegionLocations() throws
IOException {

Cheers
