Re: How to get tomcat configuration inside a servlet

[Miguel Alcalde]

I'd try to use MBeans and JMX infrastructure to find out tomcat 
configuration. http://tomcat.apache.org/tomcat-5.5-doc/monitoring.html
The admin webapp depends on MBeans to 'talk' to tomcat. So try this way.
You're GREAT ;-).
Very thank you.
