Please read the make documentation on pattern rules, specifically the
section on automatic variables. 
  
  $ info make "Pattern Rules" Automatic

You're confusing targets vs dependencies (and perhaps the old suffix
rules syntax vs gnu make's). Also, I'm assuming that you know about 
the required TAB character before the echo command.

  all: someclass.class

  %.class:
	  echo $@ ;

should echo what you expect.

Please follow up in one of the gnu newsgroups, where general questions
about make is more appropriate.
