A.2. Server configuration properties

List of server configuration properties that can be found in ServerProperties class.

Table A.2. List of server configuration properties

Constant	Value	Description
ServerProperties.APPLICATION_NAME	`jersey.config.server.application.name`	Defines the application name. The name is an arbitrary user defined name which is used to distinguish between Jersey applications in the case that more applications are deployed on the same runtime (container). The name can be used for example for purposes of monitoring by JMX when name identifies to which application deployed MBeans belong to. The name should be unique in the runtime. The property does not have a default value.
ServerProperties.BV_FEATURE_DISABLE	`jersey.config.beanValidation.disable.server`	Disables Bean Validation support. Default value is `false`.
ServerProperties .BV_DISABLE_VALIDATE_ON_EXECUTABLE_OVERRIDE_CHECK	`jersey.config.beanValidation .disable.validateOnExecutableCheck.server`	Disables `@ValidateOnExecution` check. Default value is `false`.
ServerProperties.BV_SEND_ERROR_IN_RESPONSE	`jersey.config.beanValidation .enableOutputValidationErrorEntity.server`	Enables sending validation error information to the client. Default value is `false`.
ServerProperties.EMPTY_REQUEST_MEDIA_TYPE_MATCHES_ANY_CONSUMES	`jersey.config.server.empty.request.media.matches.any.consumes`	Jakarta RESTful WebServices provides `@Consumes` annotation to accept only HTTP requests with compatible HTTP `Content-Type` header. However, when the header is missing a wildcard media type is used to match the `@Consumes` annotation. HTTP/1.1 RFC recommends that missing HTTP `Content-Type` header MAY default to `application/octet-stream`. This property makes Jersey consider the missing HTTP `Content-Type` header to be `application/octet-stream` rather than a wildcard media type. However, for a resource method without an entity argument, such as for HTTP GET, a wildcard media type is still considered to accept the HTTP request for the missing HTTP `Content-Type` header. Set this property to `false`, if the empty request media type should not to match applied `@Consumes` annotation on a resource method with an entity argument. The default is `true`.
ServerProperties.FEATURE_AUTO_DISCOVERY_DISABLE	`jersey.config.server.disableAutoDiscovery`	Disables feature auto discovery on server. Default value is `false`.
ServerProperties.HTTP_METHOD_OVERRIDE	`jersey.config.server.httpMethodOverride`	Defines configuration of HTTP method overriding. This property is used by HttpMethodOverrideFilter to determine where it should look for method override information (e.g. request header or query parameters).
ServerProperties.JSON_BINDING_FEATURE_DISABLE	`jersey.config.server.disableJsonBinding`	Disables configuration of Json Processing (JSR-353) feature. Default value is `false`.
ServerProperties.JSON_PROCESSING_FEATURE_DISABLE	`jersey.config.server.disableJsonProcessing`	Disables configuration of Json Processing (JSR-353) feature. Default value is `false`.
ServerProperties.LANGUAGE_MAPPINGS	`jersey.config.server.languageMappings`	Defines mapping of URI extensions to languages. The property is used by UriConnegFilter.
ServerProperties.MEDIA_TYPE_MAPPINGS	`jersey.config.server.mediaTypeMappings`	Defines mapping of URI extensions to media types. The property is used by UriConnegFilter.
ServerProperties.METAINF_SERVICES_LOOKUP_DISABLE	`jersey.config.server.disableMetainfServicesLookup`	Disables META-INF/services lookup on server. Default value is `false`.
ServerProperties.MOXY_JSON_FEATURE_DISABLE	`jersey.config.server.disableMoxyJson`	Disables configuration of MOXy Json feature. Default value is `false`.
ServerProperties.MONITORING_ENABLED (Jersey 2.12 or later)	`jersey.config.server .monitoring.statistics.enabled`	If `true`, then application monitoring will be enabled. This will enable the possibility of injecting ApplicationInfo into resource and providers. Default value is `false`.
ServerProperties.MONITORING_STATISTICS_ENABLED	`jersey.config.server .monitoring.enabled`	If `true`, the calculation of monitoring statistics will be enabled. This will enable the possibility of injecting MonitoringStatistics into resource and providers and also the registered listeners implementing MonitoringStatisticsListener will be called when statistics are available for processing. Monitoring statistics extends basic monitoring feature. Therefore when enabled, the monitoring gets automatically enabled too (the same result as setting the property ServerProperties.MONITORING_ENABLED to `true`). Note that enabling statistics may have a negative performance impact and therefore should be enabled only when needed. Default value is `false`.
ServerProperties.MONITORING_STATISTICS_MBEANS_ENABLED	`jersey.config.server .monitoring.statistics.mbeans.enabled`	If `true` then Jersey will expose MBeans for the collected monitoring statistics. Exposed JMX MBeans are based on MonitoringStatistics data and therefore when enabled, the calculation of monitoring statistics gets automatically enabled too (the same result as setting the property ServerProperties.MONITORING_STATISTICS_ENABLED to `true`). Note that enabling MBeans for monitoring statistics may have a negative performance impact and therefore should be enabled only when needed. Default value is `false`.
ServerProperties.MONITORING_STATISTICS_REFRESH_INTERVAL (Jersey 2.10 or later)	`jersey.config.server .monitoring.statistics.refresh.interval`	Interval (in `ms`}) indicating how often will be monitoring statistics refreshed (`onStatistics` method called). Default value is `500`.
ServerProperties.OUTBOUND_CONTENT_LENGTH_BUFFER (Jersey 2.2 or later)	`jersey.config.contentLength.server.buffer`	An integer value that defines the buffer size used to buffer the outbound message entity in order to determine its size and set the value of HTTP `Content-Length` header. Default value is `8192`.
ServerProperties.PROVIDER_CLASSNAMES	`jersey.config.server.provider.classnames`	Defines one or more class names that implement application-specific resources and providers. If the property is set, the specified classes will be instantiated and registered as either application JAX-RS root resources or providers.
ServerProperties.PROVIDER_CLASSPATH	`jersey.config.server.provider.classpath`	Defines class-path that contains application-specific resources and providers. If the property is set, the specified packages will be scanned for JAX-RS root resources and providers.
ServerProperties.PROVIDER_PACKAGES	`jersey.config.server.provider.packages`	Defines one or more packages that contain application-specific resources and providers. If the property is set, the specified packages will be scanned for JAX-RS root resources and providers.
ServerProperties.PROVIDER_SCANNING_RECURSIVE	`jersey.config.server .provider.scanning.recursive`	Sets the recursion strategy for package scanning. Default value is `true`.
ServerProperties.REDUCE_CONTEXT_PATH_SLASHES_ENABLED	`jersey.config.server.reduceContextPathSlashes.enabled`	Ignores multiple slashes between a port and a context path and will resolve it as URI with only one slash. Default value is `false`.
ServerProperties.RESOURCE_VALIDATION_DISABLE	`jersey.config.server .resource.validation.disable`	Disables `Resource` validation. Default value is `false`.
ServerProperties.RESOURCE_VALIDATION_IGNORE_ERRORS	`jersey.config.server .resource.validation.ignoreErrors`	Determines whether validation of application resource models should fail even in case of a fatal validation errors. Default value is `false`.
ServerProperties.WADL_FEATURE_DISABLE	`jersey.config.server.wadl.disableWadl`	Disables WADL generation. Default value is `false`.
ServerProperties.WADL_GENERATOR_CONFIG	`jersey.config.server.wadl.generatorConfig`	Defines the wadl generator configuration that provides a WadlGenerator.
ServerProperties.RESPONSE_SET_STATUS_OVER_SEND_ERROR	`jersey.config.server.response.setStatusOverSendError`	Whenever response status is `4xx` or `5xx` it is possible to choose between `sendError` or `setStatus` on container specific `Response` implementation. E.g. on servlet container Jersey can call `HttpServletResponse.setStatus(...)` or `HttpServletResponse.sendError(...)`. Calling `sendError(...)` method usually resets entity, response headers and provide error page for specified status code (e.g. servlet `error-page` configuration). However if you want to post-process response (e.g. by servlet filter) the only way to do it is calling `setStatus(...)` on container Response object. If property value is `true` the method `Response.setStatus(...)` is used over default `Response.sendError(...)`. Type of the property value is `boolean`. The default value is `false`.
ServerProperties.TRACING	`jersey.config.server.tracing.type`	Enables/disables tracing support. Possible values are `OFF` (default), `ON_DEMAND` and `ALL`. See Section 24.2.1, “Configuration options” for more detail.
ServerProperties.TRACING_THRESHOLD	`jersey.config.server.tracing.threshold`	Sets the amount of detail provided by tracing. Possible values are `SUMMARY`, `TRACE` and `VERBOSE`. See Section 24.2.1, “Configuration options” to learn more about the levels.
ServerProperties.PROCESSING_RESPONSE_ERRORS_ENABLED	`jersey.config.server.exception.processResponseErrors`	If property value is `true` then the errors raised during response processing are tried to be handled using available response error mappers.
ServerProperties.SUBRESOURCE_LOCATOR_CACHE_SIZE	`jersey.config.server.subresource.cache.size`	An integer value that defines the size of cache for sub-resource locator models. The cache is used to provide better performance for application that uses JAX-RS sub-resource locators.
ServerProperties.SUBRESOURCE_LOCATOR_CACHE_AGE	`jersey.config.server.subresource.cache.age`	An integer value that defines the maximum age (in seconds) for cached for sub-resource locator models. The age of an cache entry is defined as the time since the last access (read) to the entry in the cache. Entry aging is not enabled by default.
ServerProperties.SUBRESOURCE_LOCATOR_CACHE_JERSEY_RESOURCE_ENABLED	`jersey.config.server.subresource.cache.jersey.resource.enabled`	If `true` then Jersey will cache Jersey resources in addition to caching sub-resource locator classes and instances (which are cached by default). To make sure the caching is effective in this case you need to return same Jersey Resource instances for same input parameters from resource method. This means that generating new Jersey Resource instances for same input parameters would not have any performance effect and it would only fill-up the cache.
ServerProperties.LOCATION_HEADER_RELATIVE_URI_RESOLUTION_RFC7231	`jersey.config.server.headers.location.relative.resolution.rfc7231`	If `true` then Jersey will resolve relative URIs in the `Location` http header against the request URI according to `RFC7231` (new HTTP Specification)
ServerProperties.LOCATION_HEADER_RELATIVE_URI_RESOLUTION_DISABLED	`jersey.config.server.headers.location.relative.resolution.disabled`	If `true`, Jersey will not resolve relative URIs in the `Location` http header.
ServerProperties.UNWRAP_COMPLETION_STAGE_IN_WRITER_ENABLE	`jersey.config.server.unwrap.completion.stage.writer.enable`	If `true` or not set, message body writer will not use `CompletionStage` as a generic type. The `CompletionStage` value will be unwrapped and the message body writer will be invoked with the unwrapped type.
LoggingFeature.LOGGING_FEATURE_LOGGER_NAME_SERVER	`jersey.config.server.logging.logger.name`	Logger name of the logging filter. See logging chapter for more information. The default value is `org.glassfish.jersey.logging.LoggingFeature`
LoggingFeature.LOGGING_FEATURE_LOGGER_LEVEL_SERVER	`jersey.config.server.logging.logger.level`	Level of logging filter's logger at which the messages will be logged. See logging chapter for more information.
LoggingFeature.LOGGING_FEATURE_VERBOSITY_SERVER	`jersey.config.server.logging.verbosity`	Verbosity of logging filter describes how verbose the logging filter will be. There are 3 possible values `LoggingFeature.Verbosity.HEADERS_ONLY`, `LoggingFeature.Verbosity.PAYLOAD_TEXT` or `LoggingFeature.Verbosity.PAYLOAD_ANY`. See logging chapter for more information.
LoggingFeature.LOGGING_FEATURE_MAX_ENTITY_SIZE_SERVER	`jersey.config.server.logging.entity.maxSize`	The maximum number of bytes of the entity which will be logged. See logging chapter for more information.
LoggingFeature.LOGGING_FEATURE_SEPARATOR_SERVER	`jersey.config.server.logging.entity.separator`	Custom delimiter for new lines separation. See logging chapter for more information.
LoggingFeature.LOGGING_FEATURE_REDACT_HEADERS_SERVER	`jersey.config.server.logging.headers.redact`	The HTTP headers (semicolon separated) to be redacted when logging. See logging chapter for more information.

NOTE: Enabling this property may cause security related warnings/errors and it may break when other JDK implementation is used. Use only when you know what you are doing. The value MUST be an instance of `Boolean`. The default value is `false`. Since JDK 16 the JDK internal classes are not opened for reflection and the workaround method does not work, unless `--add-opens java.base/java.net=ALL-UNNAMED` for HTTP requests and additional `--add-opens java.base/sun.net.www.protocol.https=ALL-UNNAMED` for HTTPS (`javax.net.ssl.HttpsUrlConnection`) options are set.
HttpUrlConnectorProvider.USE_FIXED_LENGTH_STREAMING	`jersey.config.client.httpUrlConnector.useFixedLengthStreaming`	If `true`, the `HttpUrlConnector` (if used) will assume the content length from the value of `jakarta.ws.rs.core.HttpHeaders#CONTENT_LENGTH` request header (if present). When this property is enabled and the request has a valid non-zero content length value specified in its `jakarta.ws.rs.core.HttpHeaders#CONTENT_LENGTH` request header, that this value will be used as an input to the `java.net.HttpURLConnection#setFixedLengthStreamingMode(int)` method call invoked on the underlying `java.net.HttpURLConnection`. This will also suppress the entity buffering in the `HttpURLConnection`, which is undesirable in certain scenarios, e.g. when streaming large entities. Note that the content length value defined in the request header must exactly match the real size of the entity. If the `jakarta.ws.rs.core.HttpHeaders#CONTENT_LENGTH` header is explicitly specified in a request, this property will be ignored and the request entity will be still buffered by the underlying `HttpURLConnection` infrastructure. This property also overrides the behaviour enabled by the ClientProperties.CHUNKED_ENCODING_SIZE property. Chunked encoding will only be used, if the size is not specified in the header of the request. Note that this property only applies to client run-times that are configured to use the default `HttpUrlConnector` as the client connector. The property is ignored by other connectors. The default value is `false`.

HttpUrlConnector.SET_METHOD_WORKAROUND

jersey.config.client.httpUrlConnection.setMethodWorkaround

A value of true declares that the client will try to set unsupported HTTP method to java.net.HttpURLConnection via reflection as a workaround for a missing HTTP method.

NOTE: Enabling this property may cause security related warnings/errors and it may break when other JDK implementation is used. Use only when you know what you are doing.

The value MUST be an instance of Boolean. The default value is false.

Since JDK 16 the JDK internal classes are not opened for reflection and the workaround method does not work, unless --add-opens java.base/java.net=ALL-UNNAMED for HTTP requests and additional --add-opens java.base/sun.net.www.protocol.https=ALL-UNNAMED for HTTPS (javax.net.ssl.HttpsUrlConnection) options are set.

HttpUrlConnectorProvider.USE_FIXED_LENGTH_STREAMING

jersey.config.client.httpUrlConnector.useFixedLengthStreaming

If true, the HttpUrlConnector (if used) will assume the content length from the value of jakarta.ws.rs.core.HttpHeaders#CONTENT_LENGTH request header (if present).

When this property is enabled and the request has a valid non-zero content length value specified in its jakarta.ws.rs.core.HttpHeaders#CONTENT_LENGTH request header, that this value will be used as an input to the java.net.HttpURLConnection#setFixedLengthStreamingMode(int) method call invoked on the underlying java.net.HttpURLConnection. This will also suppress the entity buffering in the HttpURLConnection, which is undesirable in certain scenarios, e.g. when streaming large entities.

Note that the content length value defined in the request header must exactly match the real size of the entity. If the jakarta.ws.rs.core.HttpHeaders#CONTENT_LENGTH header is explicitly specified in a request, this property will be ignored and the request entity will be still buffered by the underlying HttpURLConnection infrastructure.

This property also overrides the behaviour enabled by the ClientProperties.CHUNKED_ENCODING_SIZE property. Chunked encoding will only be used, if the size is not specified in the header of the request.

Note that this property only applies to client run-times that are configured to use the default HttpUrlConnector as the client connector. The property is ignored by other connectors.

The default value is false.
