. The default resource resolver reads the schema files from the classpath and the file system. This option instead of the option resourceResolver shall be used when the resource resolver depends on the resource URI of the root schema document specified in the endpoint; for example, if you want to extend the default resource resolver. This option is also available on the validator component, so that you can set the resource resolver factory only once for all endpoints. | ||

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 schema (which is supplied on the classpath). Wiki Markup
Advanced: JMX method clearCachedSchema
Since Camel 2.17, you can force that the cached schema in the validator endpoint is cleared and reread with the next process call with the JMX operation clearCachedSchema.
You can also use this method to programmatically clear the cache. This method is available on the ValidatorEndpoint
class.
Advanced: Global Option "CamelXmlValidatorAccessExternalDTD"
Since Camel 2.19, 2.18.3, and 2.17.6 the default schema factory no longer allows reading external DTDs and external DTD entities. To achieve the old behavior where it was possible to access external DTDs and DTDs entities you can set the CamelContext global option "CamelXmlValidatorAccessExternalDTD" to "true". Prior to 2.19 global options where called properties. Endpoint See Also Include Page
