The standard Jetty Distribution ships with several modules defined in ${jetty.home}/modules/.
These modules allow flexibility for implementations and make configuration a much more plug-and-play set up.
What a Jetty Startup Module Defines:
--module=<name> command line argument to activate/enable modules, and also find dependent modules.
The filename of the module defines its name (eg: server.mod becomes the module named "server").[depend] section.
The list of dependencies is used to transitively resolve other modules that are deemed to be required based on the modules that you activate.
The order of modules defined in the graph of active modules is used to determine various execution order for configuration, such as Jetty IoC XML configurations, and to resolve conflicting property declarations.
Of note: there is a special section [optional] used to describe structurally dependent modules that are not technically required, but might be of use to your specific configuration.[lib] section declares a set of pathnames that follow the Jetty Base and Jetty Home path resolution rules.[xml] section declares a set of pathnames that follow the Jetty Base and Jetty Home path resolution rules.
Ideally, all XML files are parameterized to accept properties to configure the various elements of the standard configuration.
Allowing for a simplified configuration of Jetty for the vast majority of deployments.
The execution order of the Jetty IoC XML configurations is determined by the graph of active module dependencies resolved via the [depend] sections.
If the default XML is not sufficient to satisfy your needs, you can override this XML by making your own in the ${jetty.base}/etc/ directory, with the same name.
The resolution steps for Jetty Base and Jetty Home will ensure that your copy from ${jetty.base} will be picked up over the default one in ${jetty.home}.--list-modules command, modules will be groups by the first tag that exists in this section.
Modules can also be listed specifically by these tags using --list-modules=<tag name> on the command line.[ini] section is used to add or change server parameters at startup.
The [ini] section can also include a the path of a file or several files which should be made available to the server only.
This is helpful when you want to control what jars are available to deployed webapps.start.ini or start.d/*.ini files when using the --add-to-start=<name> command line argument in start.jar.
Commonly used to present some of the parameterized property options from the Jetty IoC XML configuration files also referenced in the same module.
The [ini-template] section declares this section of sample configuration.If the activation of a module requires some paths to exist, the [files] section defines them.
There are 2 modes of operation of the entries in this section.
"/" (slash), such as "webapps/", then that directory will be created if it does not yet exist in ${jetty.base}/<pathname> (eg: "webapps/" will result in ${jetty.base}/webapps/ being created).<url>:<pathname>.
Currently, the <url> must be a http:// scheme URL (please let us know if you need more schemes supported).
The <pathname> portion follows the Jetty Base and Jetty Home path resolution rules.
Example: http://repo.corp.com/maven/corp-security-policy-1.0.jar:lib/corp-security-policy.jar
This will check for the existence of lib/corp-security-policy.jar, and if it doesn’t exist, it will download the jar file from http://repo.corp.com/maven/corp-security-policy-1.0.jarTip
The default distribution has a co-mingled
${jetty.home}and${jetty.base}where the directories for${jetty.home}and${jetty.base}point to the same location. It is highly encouraged that you learn about the differences in Jetty Base vs Jetty Home and take full advantage of this setup.
Jetty ships with many modules defined in ${jetty.home}/modules.
Enabling a module is a simple process: simply add the --add-to-start syntax on the command line.
Doing this will enable the module and any dependent modules.
An example of this, with a new, empty, base directory. We can see from this output, that the directory is new.

Jetty Active XMLs:
------------------
${jetty.home}/etc/jetty.xml
${jetty.home}/etc/jetty-deploy.xml
${jetty.home}/etc/jetty-http.xmlYou now have a configured and functional server, albeit with no webapps deployed.
At this point you can place a webapp (war file) in the mybase/webapps/ directory and and start Jetty.
In the above example, when a module is activated the contents of that module file are added in ${jetty.base}/start.ini.
As additional modules are added, their contents are appended to this file.
This can be beneficial if you want all of your module configurations in a single file, but for large server instances with lots of modules it can pose a challenge to quickly find and make changes or to remove a module.
As an alternative to a single start.ini file you can opt to house modules in a ${jetty.base}/start.d directory.
Modules activated when a start.d directory exists will be stored as a single file per module.
Below is an example of a fresh ${jetty.base} that will create a start.d directory and activate several modules.

Next, we use the --add-to-start command which activates the modules and creates their respective ini files in the start.d directory.
If you have an existing start.ini file but would like to use the start.d structure for additional modules, you can use the --create-startd command as well.
Doing this will create the start.d directory and copy your existing start.ini file in to it.
Any new modules added to the server will have their own <module name>.ini file created in the start.d directory.

└── start.iniIt is not recommended to use both a ${jetty.base}/start.ini file and a ${jetty.base}/start.d directory at the same time and doing so can cause issues.
Once a module has been enabled for the server, it can be further configured to meet your needs.
This is done by editing the associated ini file for the module.
If your server setup is using a centralized ini configuration, you will edit the ${jetty.base}/server.ini file.
If you have elected to manage each module within it’s own ini file, you can find these files in the ${jetty.base}/start.d directory.
When a module is activated, a number of properties are set by default. To view these defaults, open up the associated ini file. Listed in the ini file is the associated module file and any properties that can be set.
Below is an example of the requestlog.ini file:
# ---------------------------------------
# Module: requestlog
--module=requestlog
## Logging directory (relative to $jetty.base)
# jetty.requestlog.dir=logs
## File path
# jetty.requestlog.filePath=${jetty.requestlog.dir}/yyyy_mm_dd.request.log
## Date format for rollovered files (uses SimpleDateFormat syntax)
# jetty.requestlog.filenameDateFormat=yyyy_MM_dd
## How many days to retain old log files
# jetty.requestlog.retainDays=90
## Whether to append to existing file
# jetty.requestlog.append=true
## Whether to use the extended log output
# jetty.requestlog.extended=true
## Whether to log http cookie information
# jetty.requestlog.cookies=true
## Timezone of the log entries
# jetty.requestlog.timezone=GMT
## Whether to log LogLatency
# jetty.requestlog.loglatency=falseThe first lines name the module file being called (located in {$jetty.home/modules}).
Subsequent lines list properties that can be changed as well as a description for each property.
To edit a property, first un-comment the line by deleting the # at the start of the line, then make the change after = sign (such as changing a true value to false).
Disabling a module is an easy process.
To disable a module, comment out the --module= line in the associated ini file.
Deleting the ini file associated with module is another option, but may not be practical in all situations.
To see which modules are available, use the --list-modules command line argument.
This command will also show you which modules are enabled.
Modules are sorted by the value in the [tags] section of the associated .mod file.
If there are multiple entries in the [tags] section, it sorts by the first tag in the list.
Note
By default, the
--list-modulescommand line argument shows all modules that do not includeinternalin the[tags]section of the associated.modfile. If you would like to see all modules, use--list-modules=*
Here’s an example of the --list-modules command:
[mybase]$ java -jar ../start.jar --list-modules

: SSL properties may be interpreted by the unixsocket-secure
: module to indicate secure HTTPS traffic. Typically this
: is an alternate to the forwarded module.

XML: etc/sessions/id-manager.xmlSince the introduction of the module system, many new modules have been added.
As a result, looking at the module list as a whole can be somewhat overwhelming.
To narrow down which modules you would like to choose from, you can search by values listed under the [tags] section.
Note that when you search this way, all modules that include your criteria in it’s [tags] section, including internal modules, will be shown.
To filter out internal modules when searching a specific module tag, simply add -internal to the command line.
For example, if you wanted to look at only the logging modules (excluding the internal implementation modules), you would use --list-modules=logging,-internal.
[mybase]$ java -jar ../start.jar --list-modules=logging,-internal
