Chapter 28. Jing

Jing Component

The Jing component uses the Jing Library to perform XML validation of the message body using either

Note that the MSV component can also support RelaxNG XML syntax.

URI format

rng:someLocalOrRemoteResource
rnc:someLocalOrRemoteResource

Where rng means use the RelaxNG XML Syntax whereas rnc means use RelaxNG Compact Syntax. The following examples show possible URI values

Example	Description
rng:foo/bar.rng	Will take the XML file foo/bar.rng on the classpath
rnc:http://foo.com/bar.rnc	Will use the RelaxNG Compact Syntax file from the URL http://foo.com/bar.rnc

Example

The following example shows how to configure a route from 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 RelaxNG Compact Syntax schema (which is supplied on the classpath).

<camelContext xmlns="http://camel.apache.org/schema/spring">
    <route>
        <from uri="direct:start"/>
        <doTry>
            <to uri="rnc:org/apache/camel/component/validator/jing/schema.rnc"/>
            <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>
