Chapter 174. Jetty 9 Component

httpUri

Required The url of the HTTP endpoint to call.

URI

chunked (common)

If this option is false the Servlet will disable the HTTP streaming and set the content-length header on the response

true

boolean

disableStreamCache (common)

Determines whether or not the raw input stream from Servlet is cached or not (Camel will read the stream into a in memory/overflow to file, Stream caching) cache. By default Camel will cache the Servlet input stream to support reading it multiple times to ensure it Camel can retrieve all data from the stream. However you can set this option to true when you for example need to access the raw stream, such as streaming it directly to a file or other persistent store. DefaultHttpBinding will copy the request input stream into a stream cache and put it into message body if this option is false to support reading the stream multiple times. If you use Servlet to bridge/proxy an endpoint then consider enabling this option to improve performance, in case you do not need to read the message payload multiple times. The http/http4 producer will by default cache the response body stream. If setting this option to true, then the producers will not cache the response body stream but use the response stream as-is as the message body.

false

boolean

enableMultipartFilter (common)

Whether Jetty org.eclipse.jetty.servlets.MultiPartFilter is enabled or not. You should set this value to false when bridging endpoints, to ensure multipart requests is proxied/bridged as well.

false

boolean

headerFilterStrategy (common)

To use a custom HeaderFilterStrategy to filter header to and from Camel message.

HeaderFilterStrategy

transferException (common)

If enabled and an Exchange failed processing on the consumer side, and if the caused Exception was send back serialized in the response as a application/x-java-serialized-object content type. On the producer side the exception will be deserialized and thrown as is, instead of the HttpOperationFailedException. The caused exception is required to be serialized. This is by default turned off. If you enable this then be aware that Java will deserialize the incoming data from the request to Java and that can be a potential security risk.

false

boolean

httpBinding (common)

To use a custom HttpBinding to control the mapping between Camel message and HttpClient.

HttpBinding

async (consumer)

Configure the consumer to work in async mode

false

boolean

bridgeErrorHandler (consumer)

Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.

false

boolean

continuationTimeout (consumer)

Allows to set a timeout in millis when using Jetty as consumer (server). By default Jetty uses 30000. You can use a value of = 0 to never expire. If a timeout occurs then the request will be expired and Jetty will return back a http error 503 to the client. This option is only in use when using Jetty with the Asynchronous Routing Engine.

30000

Long

enableCORS (consumer)

If the option is true, Jetty server will setup the CrossOriginFilter which supports the CORS out of box.

false

boolean

false

boolean

responseBufferSize (consumer)

To use a custom buffer size on the javax.servlet.ServletResponse.

Integer

sendDateHeader (consumer)

If the option is true, jetty server will send the date header to the client which sends the request. NOTE please make sure there is no any other camel-jetty endpoint is share the same port, otherwise this option may not work as expected.

false

boolean

sendServerVersion (consumer)

If the option is true, jetty will send the server header with the jetty version information to the client which sends the request. NOTE please make sure there is no any other camel-jetty endpoint is share the same port, otherwise this option may not work as expected.

true

boolean

sessionSupport (consumer)

Specifies whether to enable the session manager on the server side of Jetty.

false

boolean

useContinuation (consumer)

Whether or not to use Jetty continuations for the Jetty Server.

Boolean

eagerCheckContentAvailable (consumer)

Whether to eager check whether the HTTP requests has content if the content-length header is 0 or not present. This can be turned on in case HTTP clients do not send streamed data.

false

boolean

exceptionHandler (consumer)

To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this option is not in use. By default the consumer will deal with exceptions, that will be logged at WARN or ERROR level and ignored.

ExceptionHandler

exchangePattern (consumer)

Sets the exchange pattern when the consumer creates an exchange.

ExchangePattern

filterInitParameters (consumer)

Configuration of the filter init parameters. These parameters will be applied to the filter list before starting the jetty server.

Map

filtersRef (consumer)

Allows using a custom filters which is putted into a list and can be find in the Registry. Multiple values can be separated by comma.

String

handlers (consumer)

Specifies a comma-delimited set of Handler instances to lookup in your Registry. These handlers are added to the Jetty servlet context (for example, to add security). Important: You can not use different handlers with different Jetty endpoints using the same port number. The handlers is associated to the port number. If you need different handlers, then use different port numbers.

String

httpBindingRef (consumer)

Deprecated Option to disable throwing the HttpOperationFailedException in case of failed responses from the remote server. This allows you to get all responses regardless of the HTTP status code.

String

multipartFilter (consumer)

Allows using a custom multipart filter. Note: setting multipartFilterRef forces the value of enableMultipartFilter to true.

Filter

multipartFilterRef (consumer)

Deprecated Allows using a custom multipart filter. Note: setting multipartFilterRef forces the value of enableMultipartFilter to true.

String

optionsEnabled (consumer)

Specifies whether to enable HTTP OPTIONS for this Servlet consumer. By default OPTIONS is turned off.

false

boolean

traceEnabled (consumer)

Specifies whether to enable HTTP TRACE for this Servlet consumer. By default TRACE is turned off.

false

boolean

bridgeEndpoint (producer)

If the option is true, HttpProducer will ignore the Exchange.HTTP_URI header, and use the endpoint’s URI for request. You may also set the option throwExceptionOnFailure to be false to let the HttpProducer send all the fault response back.

false

boolean

Specifies whether a Connection Close header must be added to HTTP Request. By default connectionClose is false.

false

boolean

cookieHandler (producer)

To set a value for maximum number of threads in HttpClient thread pool. This setting override any setting configured on component level. Notice that both a min and max size must be configured. If not set it default to max 254 threads used in Jettys thread pool.

254

Integer

httpClientMinThreads (producer)

To set a value for minimum number of threads in HttpClient thread pool. This setting override any setting configured on component level. Notice that both a min and max size must be configured. If not set it default to min 8 threads used in Jettys thread pool.

If this option is true, The http producer won’t read response body and cache the input stream

false

boolean

preserveHostHeader (producer)

If the option is true, HttpProducer will set the Host header to the value contained in the current exchange Host header, useful in reverse proxy applications where you want the Host header received by the downstream server to reflect the URL called by the upstream client, this allows applications which use the Host header to generate accurate URL’s for a proxied service

false

boolean

throwExceptionOnFailure (producer)

Option to disable throwing the HttpOperationFailedException in case of failed responses from the remote server. This allows you to get all responses regardless of the HTTP status code.

true

boolean

httpClient (producer)

Sets a shared HttpClient to use for all producers created by this endpoint. By default each producer will use a new http client, and not share. Important: Make sure to handle the lifecycle of the shared client, such as stopping the client, when it is no longer in use. Camel will call the start method on the client to ensure its started when this endpoint creates a producer. This options should only be used in special circumstances.

HttpClient

httpClientParameters (producer)

Configuration of Jetty’s HttpClient. For example, setting httpClient.idleTimeout=30000 sets the idle timeout to 30 seconds. And httpClient.timeout=30000 sets the request timeout to 30 seconds, in case you want to timeout sooner if you have long running request/response calls.
