# Control Script for the CATALINA Server

#

# Environment Variable Prerequisites

#

#   Do not set the variables in this script. Instead put them into a script

#   setenv.sh in CATALINA_BASE/bin to keep your customizations separate.

#

#   CATALINA_HOME   May point at your Catalina "build" directory.

#

#   CATALINA_BASE   (Optional) Base directory for resolving dynamic portions

#                   of a Catalina installation.  If not present, resolves to

#                   the same directory that CATALINA_HOME points to.

#

#   CATALINA_OUT    (Optional) Full path to a file where stdout and stderr

#                   will be redirected.

#                   Default is $CATALINA_BASE/logs/catalina.out

#

#   CATALINA_OPTS   (Optional) Java runtime options used when the "start",

#                   "run" or "debug" command is executed.

#                   Include here and not in JAVA_OPTS all options, that should

#                   only be used by Tomcat itself, not by the stop process,

#                   the version command etc.

#                   Examples are heap size, GC logging, JMX ports etc.

#

#   CATALINA_TMPDIR (Optional) Directory path location of temporary directory

#                   the JVM should use (java.io.tmpdir).  Defaults to

#                   $CATALINA_BASE/temp.

#

#   JAVA_HOME       Must point at your Java Development Kit installation.

#                   Required to run the with the "debug" argument.

#

#   JRE_HOME        Must point at your Java Runtime installation.

#                   Defaults to JAVA_HOME if empty. If JRE_HOME and JAVA_HOME

#                   are both set, JRE_HOME is used.

#

#   JAVA_OPTS       (Optional) Java runtime options used when any command

#                   is executed.

#                   Include here and not in CATALINA_OPTS all options, that

#                   should be used by Tomcat and also by the stop process,

#                   the version command etc.

#                   Most options should go into CATALINA_OPTS.

#

#   JAVA_ENDORSED_DIRS (Optional) Lists of of colon separated directories

#                   containing some jars in order to allow replacement of APIs

#                   created outside of the JCP (i.e. DOM and SAX from W3C).

#                   It can also be used to update the XML parser implementation.

#                   This is only supported for Java <= .

#                   Defaults to $CATALINA_HOME/endorsed.

#

#   JPDA_TRANSPORT  (Optional) JPDA transport used when the "jpda start"

#                   command is executed. The default is "dt_socket".

#

#   JPDA_ADDRESS    (Optional) Java runtime options used when the "jpda start"

#                   command is executed. The default is localhost:.

#

#   JPDA_SUSPEND    (Optional) Java runtime options used when the "jpda start"

#                   command is executed. Specifies whether JVM should suspend

#                   execution immediately after startup. Default is "n".

#

#   JPDA_OPTS       (Optional) Java runtime options used when the "jpda start"

#                   command is executed. If used, JPDA_TRANSPORT, JPDA_ADDRESS,

#                   and JPDA_SUSPEND are ignored. Thus, all required jpda

#                   options MUST be specified. The default is:

#

#                   -agentlib:jdwp=transport=$JPDA_TRANSPORT,

#                       address=$JPDA_ADDRESS,server=y,suspend=$JPDA_SUSPEND

#

#   JSSE_OPTS       (Optional) Java runtime options used to control the TLS

#                   implementation when JSSE is used. Default is:

#

#   CATALINA_PID    (Optional) Path of the file which should contains the pid

#                   Example (all one line)

#                   Example (all one line)

#

#   USE_NOHUP       (Optional) If set to the string true the start command will
