I believe that the OP was wondering about the apparent discrepancy between his setting of 
the JAVA_HOME environment variable, and then what Tomcat prints as a "java.library.path" 
in the log messages.
(And I do not know if there is actually here a real discrepancy; just that the OP mentions 
there might be one).
