You're making method calls in the sample you posted. java.lang.String  
has a "length" method, but no method named "isEmpty". Here is (one  
version of) a page with docs for java.lang.String:

http://java.sun.com/j2se/1.4.2/docs/api/java/lang/String.html

You might also consider these Clojure functions:

user=> (count "")
0
user=> (empty? "")
true
user=>
