JBI

JBI Component

The jbi: component is provided by the ServiceMix Camel module and provides integration with a JBI Normalized Message Router such as provided by Apache ServiceMix

Following code

from("jbi:endpoint:http://foo.bar.org/MyService/MyEndpoint")

automatically exposes new endpoint to the bus where service qname is {http://foo.bar.org}MyService and endpoint name is MyEndpoint (refer to URI format later).

All that has to be done to use this endpoint is to send messages from some endpoint already declared (for example with jms:endpoint) to this JBI camel endpoint (the same way as messages are sent to EIP endpoints or any other endpoint) and camel will pick it up the same way as it picks any other messages.

Sending works in the same way:

to("jbi:endpoint:http://foo.bar.org/MyService/MyEndpoint")

Is used to send messages to JBI endpoint already deployed to the bus. It could be an endpoint exposed by jms:endpoint, http:provider or anything else.

URI format

jbi:service:serviceNamespace[sep]serviceName
jbi:endpoint:serviceNamespace[sep]serviceName[sep]endpointName
jbi:name:endpointName

The separator used will be:

'/' if the namespace looks like 'http://'
':' if the namespace looks like 'urn:foo:bar'

For more details of valid JBI URIs see the ServiceMix URI Guide.

Using the jbi:service: or jbi:endpoint: URI forms will set the service QName on the JBI endpoint to the exact one you give. Otherwise the default Camel JBI Service QName will be used which is

{http://activemq.apache.org/camel/schema/jbi}endpoint

Examples

jbi:service:http://foo.bar.org/MyService
jbi:endpoint:urn:foo:bar:MyService:MyEndpoint
jbi:endpoint:http://foo.bar.org/MyService/MyEndpoint
jbi:name:cheese

URI options

Name	Default value	Description
mep	<MEP of Camel Exchange>	Allows users to override the MEP being used for interacting with JBI (values are `in-only`, `in-out`, `robust-in-out` and `in-optional-out`)

Examples

jbi:service:http://foo.bar.org/MyService?mep=in-out       (override the MEP, use InOut JBI MessageExchanges)
jbi:endpoint:urn:foo:bar:MyService:MyEndpoint?mep=in      (override the MEP, use InOnly JBI MessageExchanges)

Creating a JBI Service Unit

If you have some Camel routes you want to deploy inside JBI as a Service Unit you can use the JBI Service Unit Archetype to create a new project.

If you have an existing maven project which you need to convert into a JBI Service Unit you may want to refer to the ServiceMix Maven JBI Plugins for further help. Basically you just need to make sure

you have a spring XML file at src/main/resources/camel-context.xml which is used to boot up your routes inside the JBI Service Unit
you change the pom's packaging to jbi-service-unit

Your pom.xml should look something like this to enable the jbi-service-unit packaging.
