AS2

Since Camel 2.22

Both producer and consumer are supported

The AS2 component provides transport of EDI messages using the HTTP transfer protocol as specified in RFC4130.

This component is currently a work in progress. Expect URI options and path and query parameters to change in future versions of this component.

Maven users will need to add the following dependency to their pom.xml for this component:

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-as2</artifactId>
    <version>x.x.x</version>
    <!-- use the same version as your Camel core version -->
</dependency>

URI format

as2://apiName/methodName

apiName can be one of:

  • client

  • server

AS2 Options

The AS2 component supports 4 options, which are listed below.

Name Description Default Type

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

lazyStartProducer (producer)

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.

false

boolean

basicPropertyBinding (advanced)

Deprecated Whether the component should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities

false

boolean

API Parameters (2 APIs):

The AS2 endpoint is an API based component and has additional parameters based on which API name and API method is used. The API name and API method is located in the endpoint URI as the apiName/methodName path parameters:

as2:apiName/methodName

There are 2 API names as listed in the table below:

API Name Type Description

client

Producer

Sends EDI Messages over HTTP

server

Consumer

Each API is documented in the following sections to come.

API: client

Only producer is supported

The client API has 1 method(s) which is represented by the following method signatures (an API method may have multiple signatures due to overloading):

Any of the parameters can be provided in either the endpoint URI, or dynamically in a message header. The message header name must be of the format CamelAs2.parameter. The inBody parameter overrides message header, i.e. the endpoint parameter inBody=myParameterNameHere would override a CamelAs2.myParameterNameHere header.

In addition to the parameters above, the server API can also use from the 32 endpoint query option which is listed in the Query Parameters section.

Any of the parameters can be provided in either the endpoint URI, or dynamically in a message header. The message header name must be of the format CamelAs2.parameter. The inBody parameter overrides message header, i.e. the endpoint parameter inBody=myParameterNameHere would override a CamelAs2.myParameterNameHere header.

Spring Boot Auto-Configuration

When using as2 with Spring Boot make sure to use the following Maven dependency to have support for auto configuration:

<dependency>
  <groupId>org.apache.camel.springboot</groupId>
  <artifactId>camel-as2-starter</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>

The component supports 5 options, which are listed below.

Name Description Default Type

camel.component.as2.autowired-enabled

Whether autowiring is enabled. This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component. This can be used for automatic configuring JDBC data sources, JMS connection factories, AWS Clients, etc.

true

Boolean

camel.component.as2.bridge-error-handler

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

camel.component.as2.configuration

Component configuration. The option is a org.apache.camel.component.as2.AS2Configuration type.

AS2Configuration

camel.component.as2.enabled

Whether to enable auto configuration of the as2 component. This is enabled by default.

Boolean

camel.component.as2.lazy-start-producer

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.
