WEB-INF/lib ignored in Tomcat 6

It seems that Tomcat 6 is not finding the jars in the application 
library WEB-INF/lib.

If I put the spring.jar in the tomcat lib directory it is found.
If I put it in the application lib directory it is not found.

If I fix the spring.jar issue, I just get an Class not found error on 
the next library.

Hi Ron--

.\META-INF\context.xml has a reloadable attribute which must be set to true to tell tomcat to monitor jars in .\WEB-INF\lib
http://tomcat.apache.org/tomcat-5.5-doc/config/loader.html

also take a look at the delegate attribute to specifically load classes via parent class loader before looking in WEB-INF

HTH,
