Field Detail

JETTY_PORT

static final String JETTY_PORT

The name of the system property that can be used to override the default HTTP port in the bundled jetty.xml file.

Constant Field Values

JETTY_XML

static final String JETTY_XML

The name of the system property that can be used to override the location of the jetty.xml file that will be used to configure jetty (default "jetty.xml").

DEFAULT_JETTY_XML

static final String DEFAULT_JETTY_XML

The default value works when deployed under the IDE with the bigdata-war/src directory on the classpath. When deploying outside of that context, the value needs to be set explicitly.

JETTY_STARTUP_TIMEOUT

static final String JETTY_STARTUP_TIMEOUT

The timeout in seconds that we will await the start of the jetty Server (default ).

static final String JETTY_DUMP_START

When true, the state of jetty will be dumped onto a logger after the server start.

JETTY_RESOURCE_BASE

static final String JETTY_RESOURCE_BASE

This property specifies the resource path for the web application. In order for this mechanism to work, the jetty.xml file MUST contain a line which allows the resourceBase of the web application to be set from an environment variable. For example:

 <SystemProperty name="jetty.resourceBase" default="bigdata-war/src" />
 

The jetty.resourceBase variable may identify either a file or a resource on the class path. To force the use of the web application embedded within the bigdata.jar you need to specify a JAR URL along the following lines (using the appropriate file path and jar name and version:

 jar:file:../lib/bigdata-1.3.0.jar!/bigdata-war/src
 

The use of absolute file paths are recommended for reliable resolution.

The order of preference is:

1. jetty.resourceBase is specified. The value of this environment variable will be used to locate the web application.
2. jetty.resourceBase is not specified (either null or whitespace).
   1. An attempt is made to locate the bigdata-war/src resource in the file system (relative to the current working directory). If found, the jetty.resourceBase environment variable is set to this resource using a file: style URL. This will cause jetty to use the web application directory in the file system.
   2. An attempt is made to locate the resource /WEB-INF/web.xml using the classpath (this handles the case when running under the eclipse IDE). If found, the the jetty.resourceBase is set to the URL formed by removing the trailing WEB-INF/web.xml for the located resource. This will cause jetty to use the web application resource on the classpath. If there are multiple such resources on the classpath, the first such resource will be discovered and used.
   3. An attempt is made to locate the resource bigdata-war/src/main/webapp/WEB-INF/web.xml using the classpath (this handles the case when running from the command line using a bigdata JAR). If found, the the jetty.resourceBase is set to the URL formed by the trailing WEB-INF/web.xml for the located resource. This will cause jetty to use the web application resource on the classpath. If there are multiple such resources on the classpath, the first such resource will be discovered and used.
   4. Otherwise, the jetty.resourceBase environment variable is not modified and the default location specified in the jetty.xml file will be used. If jetty is unable to resolve that resource, then the web application will not start.

JETTY_OVERRIDE_WEB_XML

static final String JETTY_OVERRIDE_WEB_XML

The location of the override-web.xml resource. The default is given in jetty.xml and serves to locate the resource when deployed under an IDE. If not explicitly given, value of the environment variable is set by the same logic that sets the JETTY_RESOURCE_BASE environment variable. This allows the override-web.xml resource to be found in its default location (which is the same directory / package as the web.xml file) while still preserving the ability to override the location of that resource explicitly by setting the environment variable before starting the server.

BIGDATA_PROPERTY_FILE

static final String BIGDATA_PROPERTY_FILE

The location to over propertyFile used to create the servlet. This to allow overriding the default value via passing a Java Property at the command line.

JETTY_HOME

static final String JETTY_HOME

The jetty.home property.
