Possible values for protocol are
Http11NioProtocol or
AJP/1.3.
If you are not using a native Web Server as a proxy or load balancer, then specify
Http11NioProtocol.
If you are using a load balancer, and you specify AJP, then set
secretRequired=false.
Note: By default, Tomcat sets this value to
true, which can cause your service to fail.
If you modify the port, you must change the
service.url property in the
spserver.properties configuration file to reflect the new value. See
service.url for more information.
