accessing settings in server.xml from the servlet

Hi,

how can a servlet access maxThreads settings defined in server.xml? I
tried getServletContext(), getServletConfig(), getInitParameter(..),
getAttribute(..), etc, but I still can't find a way to access
server.xml
configuration. I guess I need to get ahold of the catalina engine and
the get the setting from the http connector. But what is the right way
to
do this?

Thanks.

Alec

Take a look at

Other than rolling your own infrastructure, probably not, at least not
easily.  That's what MBeans are for and why Tomcat utilizes them.

Charles ,

I agree with you that this starting point is rather terse.

Is there a way to access settings in server.xml without MBeans? I would like
to write a simple servlet that doesn't require special configuraion, such as
mbeans-descriptor.xml file.

Is it possible to get ahold of catalina engine from the servlet code and
then somehow inspect http connectors?

Thanks.

Usually via JMX.  This is your rather terse starting point:
http://tomcat.apache.org/tomcat-5.5-doc/mbeans-descriptor-howto.html

Look at code in Tomcat's manager and admin apps for examples.
