---------------------------------------

             Summary: XSLT Component: Support custom URI resolver which depends on dynamic
resource URI of the endpoint
                 Key: CAMEL-9580
                 URL: https://issues.apache.org/jira/browse/CAMEL-9580
             Project: Camel
          Issue Type: Improvement
          Components: camel-core
            Reporter: Franz Forsthofer
            Assignee: Franz Forsthofer
             Fix For: 2.17.0


The XSLT component allows already specifying custom URI resolvers via the parameter uriResolver.
However, when your custom URI resolver depends on the dynamic URI of the endpoint then the
current solution is not sufficient. Suppose you have a dynamically created XSLT endpoint,
like

 <camel:recipientList>
<camel:simple>xslt:${header.XSLT_FILE}?uriResolver=#uriResolver</camel:simple>
</camel:recipientList>

where the resource URO of the XSLT document is also dynamic (in the example via the header
XSLT_File). In this case you cannot hand-over the dynamic resource URI to the custom URI resolver.


The contribution solves this problem by introducing a new parameter uriResolverFactory where
you can specify a factdory which implements the method

URIResolver createUriResolver(CamelContext camelContext, String resourceUri)

This method is called when the endpoint is created and gives you access to the endpoint resource
URI.

We also support that the resource URI factory can be set on the component so that you must
not set the factory on each endpoint.

Further advantage of the new approach is that you can now easily extend the default resource
resolver org.apache.camel.builder.xml.XsltUriResolver which also depends on the resource URI
of the endpoint.
