compileString/compileReader in org.mozilla.javascript.Context,
http://www.mozilla.org/rhino/apidocs/org/mozilla/javascript/Context.html 
, allow to compile scripts and check for syntax errors without executing 
any JS code. To see what functions are supplied in the script, set the 
pure interpretation mode before calling the compile functions:

contextInstance.setOptimizationLevel(-1)

Then the compiled Script object would implement 
org.mozilla.javascript.debug.DebuggableScript interface which you can 
use  to enumerate declared functions.

Checking for variables is possible in principle but then you have to 
access package-private classes as there is no public API for that in Rhino.
