Mathematica 5.1 JLink problem

I've recently installed Mathematica 5.1 on a Mac OS X box (running 
Panther 10.3.7).  After copying the Mathematica bundle to 
/Applications/ as the Administrator, then switching back to my ordinary 
user account, I found that JLink could not be started.  Evaluating 
(from a fresh kernel session)


Gives, as error messages,

	The separate Java user-interface link could not be established.

	A link to the Java runtime could not be established.

However, if I evaluate the above when logged in as Administrator, JLink 
starts just fine.  JLink under Mathematica 5.0 (which I still have 
installed as well) works just fine from my ordinary user account.

Any guesses as to what might be wrong?
