# jboss_run.sh replaces run.sh or other init scripts from the JBoss install.  #
# It is used for (start|stop)ing multiple JBoss instances individually or all #
# together.                                                                   #
#                                                                             #
# Assumptions:                                                                #
#                                                                             #
# There are no contingencies for any platform other than SunOS - so use the   #
# normal scripts for other O/Ss.                                              #
#                                                                             #
# That Java and JBoss are installed in /usr/java and /usr/local/jboss.        # 
#                                                                             #
# That you're using the Java JDK, not JRE.                                    #
#                                                                             #
# That the service name you enter is configured in service-bindings.xml,      #
# otherwise an attempt is made at starting it.                                #
#                                                                             #
# Only one instance can restart at a time - needs to be specified.            #
#                                                                             #
# The instances are derived from /usr/local/jboss/server/service-bindings.xml #
# and a comment for the jnp listening port after the server name tag, e.g.    #
#                                                                             #

# The http servlet is similarly commented, allowing it's display in the list  #
# function; the comment requires the server name tag included, i.e.           #
#                                                                             #
#                 <binding port="8080"/><!--default_tcp-->                    #
#                                                                             #

# JVM Heap sizes (-Xms and -Xmx) must be set in /etc/local.d/jvm_opts.conf    #
# e.g. for the default instance using 100MB:                                  #
#                                                                             #
