Properties

Start your application server with the system property"system.properties.set" set to true to load the external file calledsystem.properties. This is given as a convenient way to ensure all propertiesare set for deployment. When the server starts, the portal will loadsystem.properties and then system-ext.properties.

Start your application server with the system property"system.properties.set.override" set to true if the properties ofsystem.properties override all similar command line properties. If set tofalse, the properties of system.properties will be set if and only if thoseproperties are not currently set.

Some application servers require you to set the "file.encoding" and"user.timezone" on startup regardless of system.properties because theapplication server reads these properties before system.properties is everloaded.

CXF

Set CXF logger class.

    org.apache.cxf.Logger=com.liferay.portal.remote.jaxrs.whiteboard.internal.log.LiferayCXFLogger

Cookie

HTTP only cookies are not supposed to be exposed to client-side scripting code, and may therefore help mitigate certain kinds of cross-site scripting attacks. Input a list of comma delimited cookie names that are not HTTP only.

Env: SYSTEM_LIFERAY_COOKIE_PERIOD_HTTP_PERIOD_ONLY_PERIOD_NAMES_PERIOD_EXCLUDES

    cookie.http.only.names.excludes=

Ehcache

Set this to true to skip the update check.

    com.liferay.util.Encryptor.provider.class=com.sun.crypto.provider.SunJCE

HTTP

See portal.properties for more HTTP settings.

Set the HTTP proxy location where the portal fetches external content.

Set http.nonProxyHosts for hosts that must not be proxied. This is useful for proxied environments where you need direct access to internal servers. Follow the same semantics as the java.net package.

Env: SYSTEM_LIFERAY_HTTP_PERIOD_NON_UPPERCASEP_ROXY_UPPERCASEH_OSTS Env: SYSTEM_LIFERAY_HTTP_PERIOD_PROXY_UPPERCASEH_OST Env: SYSTEM_LIFERAY_HTTP_PERIOD_PROXY_UPPERCASEP_ORT

    http.proxyPort=4480
    http.nonProxyHosts=192.168.0.250

HTTP Header Response

See portal.properties for more HTTP Header Response settings.

Set this to true for the portal to send the "X-Content-Type-Options: nosniff" HTTP header to protect against MIME sniffing. Custom URLs that allow for unhindered MIME sniffing are specified via the "http.header.secure.x.content.type.options.urls.excludes" property.

Env: SYSTEM_LIFERAY_HTTP_PERIOD_HEADER_PERIOD_SECURE_PERIOD_X_PERIOD_CONTENT_PERIOD_TYPE_PERIOD_OPTIONS

    http.header.secure.x.content.type.options=true

Set a list of comma-delimited URL prefixes that allow for unhindered MIME sniffing. This property is used only when the property "http.header.secure.x.content.type.options" is set to true.

Env: SYSTEM_LIFERAY_HTTP_PERIOD_HEADER_PERIOD_SECURE_PERIOD_X_PERIOD_CONTENT_PERIOD_TYPE_PERIOD_OPTIONS_PERIOD_URLS_PERIOD_EXCLUDES

    http.header.secure.x.content.type.options.urls.excludes=

Set this to true for the portal to send the "X-Frame-Options: DENY" HTTP header to protect against clickjacking.

Custom HTTP header values instead of "DENY" are specified per URL via "http.header.secure.x.frame.options.*" properties.

Env: SYSTEM_LIFERAY_HTTP_PERIOD_HEADER_PERIOD_SECURE_PERIOD_X_PERIOD_FRAME_PERIOD_OPTIONS

    http.header.secure.x.frame.options=true

If the property "http.header.secure.x.frame.options" is set to true, then the portal searches the "http.header.secure.x.frame.options.*" properties for a matching pipe-delimited URL and HTTP header value pair (e.g., "/|SAMEORIGIN"). The portal iterates through the "http.header.secure.x.frame.options.*" properties where the wildcard "*" is replaced with an integer between 0 and 255 (starting with 0).

Upon finding a matched a URL, the portal uses the custom HTTP header value instead of the "DENY" value.

By default, URLs that start with "/" use the "SAMEORIGIN" custom HTTP header value. Specify another URL and HTTP header value with a number smaller than 255 to intercept this default behavior.

Env: SYSTEM_LIFERAY_HTTP_PERIOD_HEADER_PERIOD_SECURE_PERIOD_X_PERIOD_FRAME_PERIOD_OPTIONS_PERIOD__NUMBER2__NUMBER5__NUMBER5_

    http.header.secure.x.frame.options.255=/|SAMEORIGIN

HTTPS

Input a list of comma-delimited HTTPS cipher suites allowed for HTTPS connection to a 3rd party server.

Env: SYSTEM_LIFERAY_HTTPS_PERIOD_CIPHER_UPPERCASES_UITES

    https.cipherSuites=

Input a list of comma delimited protocols allowed for HTTPS connection to a 3rd party server. For example -Dhttps.protocols=TLSv1.1,TLSv1.2 disables outbound TLS 1.0 connections.

Java

The file encoding must be set to UTF-8 for internationalization to work correctly.

Env: SYSTEM_LIFERAY_FILE_PERIOD_ENCODING

    file.encoding=UTF-8

Java uses the underlying operating system to generate images. If you are using Unix and do not start the portal in an X Windows session, then Java does not generate images and lots of nasty exceptions are thrown. Setting this property to true fixes that. If this property does not set dynamically on server startup, edit your start script to include this setting as a system property.

Env: SYSTEM_LIFERAY_JAVA_PERIOD_AWT_PERIOD_HEADLESS

    java.awt.headless=true

Set the default locale to use. This locale is no longer set at the VM level. See LEP-2584.

    user.country=US

Java Advanced Imaging

JAI relies on native acceleration to improve performance. To use native acceleration, you must install the appropriate native libraries and set this property to false. Warnings are reported if this is set to false without installing the proper native libraries.

Java Architecture for XML Binding

Specify the JAXB context factory to avoid using the one detected by context. This forces Java to use the same implementation instead of different implementations for different Java versions. Set this property to a blank value to use the auto-detected JAXB context factory.

JRuby

Set this to true to enable native extensions (like JNA for non-Java APIs).

Env: SYSTEM_LIFERAY_JRUBY_PERIOD_NATIVE_PERIOD_ENABLED

    jruby.native.enabled=false

Log Sanitizer

Set this to true to enable the log sanitizer, which is a safe logging mechanism that avoids directly embedding user input in log files. The log sanitizer automatically sanitizes log messages by replacing all unexpected characters from user supplied data with safe replacement characters.

See the "log.sanitizer.escape.html.enabled" property to encode HTML entities in log messages.

Env: SYSTEM_LIFERAY_LOG_PERIOD_SANITIZER_PERIOD_ENABLED

    log.sanitizer.enabled=true

Set this to true to encode HTML data in log messages.

Env: SYSTEM_LIFERAY_LOG_PERIOD_SANITIZER_PERIOD_ESCAPE_PERIOD_HTML_PERIOD_ENABLED

    log.sanitizer.escape.html.enabled=false

Specify the code point of the character to replace forbidden characters. The underscore character, which has code point 95, is the default replacement character.

Env: SYSTEM_LIFERAY_LOG_PERIOD_SANITIZER_PERIOD_REPLACEMENT_PERIOD_CHARACTER

    log.sanitizer.replacement.character=95

Specify characters to allow in log messages. The sanitizer operates on characters with code points less than 128. Characters with code points greater than 128 are always allowed. Please see ASCII tables to look up character code points.

This default whitelist allows characters with code points 9 (tab), 32 (space), and all characters with code points greater than 32 except 127 (delete).

Env: SYSTEM_LIFERAY_LOG_NUMBER4_J_NUMBER2__PERIOD_DISABLE_PERIOD_JMX

    log4j2.disable.jmx=true

Set this to true to enable org.apache.logging.log4j.web.WebLookup. Liferay does not use Log4j 2 in webapp mode.

Set this property to tell StringBundler when to use a ThreadLocal buffer to build the output String. SoftReference marks the buffer to be removed forcibly by the GC when memory is nearly exhausted. Set the limit to a high value to balance ThreadLocal access by the garbage collection savings. Setting the limit too low may actually do more harm than good.

Set a value larger than 0 to enable this feature when using StringBundler with an output length longer than the specified value. A reasonable value is 8192 (8 kb) or 16384 (16 kb). The best value depends on how the portal is used.
