You can't redirect stderr separate from stdout in csh, only both, like
this:

  javac file.java |& head -10
  javac file.java |& more

(man csh:
        A simple command, or a set of simple commands separated by |
     or |& characters, forms a pipeline. With |, the standard output
     of the preceding command is redirected to the standard input of
     the command that follows. With |&, both the standard error and
     the standard output are redirected through the pipeline.
)

So if there is stdout-output as well, you might have to wrap Joe's
suggestion inside a call to sh -c, or just invoke sh for that single
command.
