By looking at the runtime attributes of the web connector, some of them, are exposed in the .xsd file. Here's a sample connector configuration:
<connector enable-lookups="false" enabled="true"
executor="idvalue0" max-connections="200"
max-post-size="" max-save-post-size="4096"
name="http" protocol="HTTP/1.1"
proxy-name="proxy" proxy-port="8081"
redirect-port="8443" scheme=""
secure="false" socket-binding="http" />
I guess that max-connections should map to maxThreads.
By the way: the element executor is mentioned, does it reference an executor from JBoss Thread's pool or rather an Executor element to be defined in the Web subsystem ? (Just like Tomcat 6 and onwards).
