I see where you're getting mislead. There should be two properties
files. One for workers (referenced by JkWorkersFilefrom httpd.conf) and
another one for Connector (referenced by
server-config.network-config.network-listeners.network-listener.jk-connector.jk-configuration-file).
The above example uses glassfish-jk.properties as the file name for
JkWorkersFile to define workers info where I was using
glassfish-jk.properties name to refer to the other (Connector attributes).
Try adding the following to apache/conf/httpd.conf and add worker info
in workers.properties
JkWorkersFile conf/workers.properties
Add maxThreads=256 to glassfish-jk.properties and set it either using
admin console or asadmin set command.
set
server-config.network-config.network-listeners.network-listener.jk-connector.jk-configuration-file=/home/glassfish/glassfish3/glassfish/domains/domain1/config/glassfish-jk.properties
You can find the format of Properties from
http://docs.oracle.com/javase/6/docs/api/java/util/Properties.html. See
load for key/element examples.
I will relay this input to the docs team to update the docs to be more
clear in the next release.
Thanks,
Amy
