Embedded Web Server

Apache ActiveMQ Artemis embeds the Jetty web server. Its main purpose is to host the Management Console. However, it can also host other web applications like the REST interface or even Spring-based web applications (e.g. using Camel).

Configuration

The embedded Jetty instance is configured in etc/bootstrap.xml via the web element, e.g.:

<web path="web">
   <binding uri="http://localhost:8161">
      <app url="activemq-branding" war="activemq-branding.war"/>
      <app url="artemis-plugin" war="artemis-plugin.war"/>
      <app url="console" war="console.war"/>
   </binding>
</web>

The web element has the following attributes:

  • path The name of the subdirectory in which to find the web application archives (i.e. WAR files). This is a subdirectory of the broker's home or instance directory.
  • customizer The name of customizer class to load.

The web element should contain at least one binding element to configure how clients can connect to the web-server. A binding element has the following attributes:

  • uri The protocol to use (i.e. http or https) as well as the host and port on which to listen. This attribute is required.
  • clientAuth Whether or not clients should present an SSL certificate when they connect. Only applicable when using https.
  • passwordCodec The custom coded to use for unmasking the keystorePassword and trustStorePassword.
  • keyStorePath The location on disk of the keystore. Only applicable when using https.
  • keyStorePassword The password to the keystore. Only applicable when using https. Can be masked using ENC() syntax or by defining passwordCodec. See more in the password masking chapter.
  • trustStorePath The location on disk for the truststore. Only applicable when using https.
  • trustStorePassword The password to the truststore. Only applicable when using https. Can be masked using ENC() syntax or by defining passwordCodec. See more in the password masking chapter.
  • includedTLSProtocols A comma seperated list of included TLS protocols, ie "TLSv1,TLSv1.1,TLSv1.2". Only applicable when using https.
  • excludedTLSProtocols A comma seperated list of excluded TLS protocols, ie "TLSv1,TLSv1.1,TLSv1.2". Only applicable when using https.
  • includedCipherSuites A comma seperated list of included cipher suites. Only applicable when using https.
  • excludedCipherSuites A comma seperated list of excluded cipher suites. Only applicable when using https.

Each web application should be defined in an app element inside an binding element. The app element has the following attributes:

  • url The context to use for the web application.
  • war The name of the web application archive on disk.

It's also possible to configure HTTP/S request logging via the request-log element which has the following attributes:

  • filename The full path of the request log. This attribute is required.
  • append Whether or not to append to the existing log or truncate it. Boolean flag.
  • extended Whether or not to use the extended request log format. Boolean flag.
  • logCookies Logging of the request cookies. Boolean flag.
  • logTimeZone The output file name of the request log.
  • filenameDateFormat The log file name date format.
  • retainDays The number of days before rotated log files are deleted.
  • ignorePaths Request paths that will not be logged. Comma delimited list.
  • logDateFormat The timestamp format string for request log entries.
  • logLocale The locale of the request log.
  • logLatency Logging of request processing time. Boolean flag.
  • logServer Logging of the request hostname. Boolean flag.
  • preferProxiedForAddress Whether the actual IP address of the connection or the IP address from the X-Forwarded-For header will be logged. Boolean flag.

These attributes are essentially passed straight through to the underlying org.eclipse.jetty.server.NCSARequestLog instance. Default values are based on this implementation.

Here is an example configuration:

<web path="web">
   <binding uri="http://localhost:8161">
      <app url="activemq-branding" war="activemq-branding.war"/>
      <app url="artemis-plugin" war="artemis-plugin.war"/>
      <app url="console" war="console.war"/>
   </binding>
   <request-log filename="${artemis.instance}/log/http-access-yyyy_MM_dd.log" append="true" extended="true"/>
</web>

Proxy Forwarding

The proxies and load balancers usually support X-Forwarded headers to send information altered or lost when a proxy is involved in the path of the request. Jetty supports the ForwardedRequestCustomizer customizer to handle X-Forwarded headers. Set the customizer attribute via the web element to enable the ForwardedRequestCustomizer customizer, ie:

<web path="web" customizer="org.eclipse.jetty.server.ForwardedRequestCustomizer">
   <binding uri="http://localhost:8161">
      <app url="activemq-branding" war="activemq-branding.war"/>
      <app url="artemis-plugin" war="artemis-plugin.war"/>
      <app url="console" war="console.war"/>
   </binding>
</web>
