FAQ
Hi,

this is actually my first day working with camel and I have to admit I
allready love it. Currently I am stuck with one last thing to have my first
camel project up and running.

I have one route that starts by loading xml files from the filesystem. A
processor then adds a client-id to the requests header based on the content
of the xml.

My customers requirement is that there are some clients that need special
processing. For these customers there should be an xsl transformation with
an uri like this:
"xslt://file:custom-transformations/${headers.gst}/convert.xslt". I have
managed to check if the file exists and to use a different path in that
case. The problem is, that Camel doesn't seem to like dynamic uris ... how
could I manage to achieve this?

Here a shortend version of my route ...
<camel:route>
<camel:from
uri="file:input?move=imported&amp;moveFailed=failed&amp;filter=#xmlInputFilter"/>
<camel:convertBodyTo type="org.w3c.dom.Document"/>

<camel:process ref="gstDataCsvProcessor"/>
<camel:choice>
<camel:when>

<method ref="applyCustomTransformationPredicate"/>

<camel:to
uri="xslt://file:custom-transformations/${headers.gst}/convert.xslt"/>
<camel:to
uri="xslt://file:xslt/ToEasySPED.xslt?contentCache=false"/>
<camel:to uri="file:output"/>
</camel:when>
<camel:otherwise>
<camel:to
uri="xslt://file:xslt/ToEasySPED.xslt?contentCache=false"/>
<camel:to uri="file:output"/>
</camel:otherwise>
</camel:choice>
</camel:route>

I would really appreciate some help with this last step.

Chris

    Hi

    Welcome on the Camel ride.

    Seems you got pretty far on your first day.

    About the dynamic to, then there is a EIP pattern for that. We have
    added a FAQ about this at
    http://camel.apache.org/how-do-i-use-dynamic-uri-in-to.html

    Hi Claus,

    thanks for that hint. I have to admit that I allready saw hints on this
    while googling around, but I thougt it didn't fit my usecase. Now I tried it
    and it works :-)

    Thanks,
    Chris
