The Validation component performs XML validation of the message body using the JAXP Validation API and based on any of the supported XML schema languages, which defaults to XML Schema
Note that the Jing component also supports the following useful schema languages:
The MSV component also supports RelaxNG XML Syntax.
validator:someLocalOrRemoteResource
Where someLocalOrRemoteResource
is some 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
XSD to validate against. For example:
msv:org/foo/bar.xsd
msv:file:../foo/bar.xsd
validator:com/mypackage/myschema.xsd
Maven users need to add the following dependency to their
pom.xml

Camel 2.8 or earlier:
<dependency> <groupId>org.apache.camel</groupId> <artifactId>camel-spring</artifactId> <version>x.x.x</version> <!-- use the same version as your Camel core version --> </dependency>
Apache Camel 2.9 onwards: The
Validation component is provided directly in camel-core
.

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 the XML matches the given schema (which is supplied on the classpath).
<camelContext xmlns="http://camel.apache.org/schema/spring"> <route> <from uri="direct:start"/> <doTry> <to uri="validator:org/apache/camel/component/validator/schema.xsd"/> <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>
