You use the setProperty method on the Connector Object (the names are the
same as in the Tomcat docs for setting it via server.xml). So something
like:
ajp13Connector.setProperty("maxThread", "200");
ajp13Connector.setProperty("minSpareThreads", "25");

ChannelSocket is the standard Java AJP/1.3 Channel for 5.5.x. With this
channel, the Threads will block after handling a request waiting for the
next request on that particular Socket to come from Apache (or until it hits
the connectionTimeout, which ever happens first).
ChannelNioSocket is the experimental (due to a lack of community interest)
non-blocking Java Channel. It works somewhat like the APR AJP/1.3 Connector
in that Threads return to the pool after processing a request. Then when
another request comes in from Apache on a Socket, it gets a Thread from the
pool, and uses it to process the request. This means that the only active
Tomcat Threads are those that are processing requests, so depending on your
site's traffic pattern means that you can possibly handle a big pool of
Socket connections between Apache and Tomcat with relatively few Threads.
To use this one, you would specify an ajp13_port value of 0 in the
createConnector call above, and use:
ajp13Connector.setProperty("channelNioSocket.port","8009"); // required
ajp13Connector.setProperty("channelNioSocket.maxThreads", "200");
...
Property name are generally the same as for ChannelSocket, but prefixed with
channelNioSocket.<property>.
