The CLI commands for setting the compression and compression-mime-type
attributes for an http listener are:
asadmin set
configs.config.server-config.network-config.protocols.protocol.http-listener-1.http.compression=on
asadmin set
configs.config.server-config.network-config.protocols.protocol.http-listener-1.http.compressable-mime-type=text/html,text/xml,text/plain,text/css
Note the use of "http" under the listener name rather than property.
Also, this is set in the config for the server rather than in the server
itself.
