= Jing Component
:page-source: components/camel-jing/src/main/docs/jing-component.adoc

*Since Camel 1.1*

// HEADER START
*Only producer is supported*
// HEADER END

The Jing component uses the
http://www.thaiopensource.com/relaxng/jing.html[Jing Library] to perform
XML validation of the message body using either

* http://relaxng.org/[RelaxNG XML Syntax]
* http://relaxng.org/compact-tutorial-20030326.html[RelaxNG Compact
Syntax]

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

[source,xml]
------------------------------------------------------------
<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-jing</artifactId>
    <version>x.x.x</version>
    <!-- use the same version as your Camel core version -->
</dependency>
------------------------------------------------------------

Note that the xref:msv-component.adoc[MSV] component can also support RelaxNG XML
syntax.

== URI format

[source,text]
------------------------------
jing:someLocalOrRemoteResource
------------------------------

The component uses jing as name, and you can use the
option compactSyntax to turn on either RNG or RNC mode.

== Options


// component options: START
The Jing component supports 3 options, which are listed below.



[width="100%",cols="2,5,^1,2",options="header"]
|===
| Name | Description | Default | Type
| *basicPropertyBinding* (advanced) | Whether the component should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities | 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
| *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
|===
// component options: END




// endpoint options: START
The Jing endpoint is configured using URI syntax:

----
jing:resourceUri
----

with the following path and query parameters:

=== Path Parameters (1 parameters):


[width="100%",cols="2,5,^1,2",options="header"]
|===
| Name | Description | Default | Type
| *resourceUri* | *Required* URL to a local resource on the classpath or a full URL to a remote resource or resource on the file system which contains the schema to validate against. |  | String
|===


=== Query Parameters (4 parameters):


[width="100%",cols="2,5,^1,2",options="header"]
|===
| Name | Description | Default | Type
| *compactSyntax* (producer) | Whether to validate using RelaxNG compact syntax or not. By default this is false for using RelaxNG XML Syntax (rng) And true is for using RelaxNG Compact Syntax (rnc) | 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) | Whether the endpoint should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities | false | boolean
| *synchronous* (advanced) | Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported). | false | boolean
|===
// endpoint options: END
// spring-boot-auto-configure options: START
== Spring Boot Auto-Configuration

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

[source,xml]
----
<dependency>
  <groupId>org.apache.camel.springboot</groupId>
  <artifactId>camel-jing-starter</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>
----


The component supports 4 options, which are listed below.



[width="100%",cols="2,5,^1,2",options="header"]
|===
| Name | Description | Default | Type
| *camel.component.jing.basic-property-binding* | Whether the component should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities | false | Boolean
| *camel.component.jing.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.jing.enabled* | Whether to enable auto configuration of the jing component. This is enabled by default. |  | Boolean
| *camel.component.jing.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. | false | Boolean

// spring-boot-auto-configure options: END




== Example

The following example shows how to configure a route from the endpoint *direct:start* which
then goes to one of two endpoints, either *mock:valid* or *mock:invalid*
based on whether or not the XML matches the given
http://relaxng.org/compact-tutorial-20030326.html[RelaxNG Compact Syntax]
schema (which is supplied on the classpath).

[source,xml]
----
    <camelContext xmlns="http://camel.apache.org/schema/spring">
        <route>
            <from uri="direct:start"/>
            <doTry>
                <to uri="jing:org/apache/camel/component/validator/jing/schema.rnc?compactSyntax=true"/>
                <to uri="mock:valid"/>
                <doCatch>
                    <exception>org.apache.camel.ValidationException</exception>
                    <to uri="mock:invalid"/>
                </doCatch>
                <doFinally>
                    <to uri="mock:finally"/>
                </doFinally>
            </doTry>
        </route>
    </camelContext>
