The following sample configuration files included with mod_jk are quite old and
do not conform to the standard optimal configuration:
This causes an issue with support, as the first support step is to ask the user to update their setup to match the standard configuration. This is especially true with 1.2.27, which introduced a new worker property, ping_mode.
Also, there really is no need to have separate JBoss samples. Really the samples are the same for JBoss and Tomcat.
I recommend removing workers.properties.jboss.sample and
I will attach revised workers.properties.sample and mod_jk.conf.sample that will apply to JBoss or Tomcat back ends.
