Set Tomcat to show deprecation warnings

[Boemio, Neil (GEI, FGI)]

When I hit a JSP page and there are errors, Tomcat shows a page with all the errors.  
If there are no errors, but there are deprecated methods being used, Tomcat does not 
show this.  Is there a way I can set it up so that deprecation warnings are shown when 
I hit a JSP page?
 
Thanks,
Neil
