All,
Greetings. I recently inherited a project built using the Camel framework
and now have to extend it. My experience is almost zero with Camel but I am
learning and reading as fast and hard as I can.
I have seen other posts that mention my situation but dont provide the
information I am looking for ( or I dont understand enough yet ) so here
goes.
In a nutshell, I need to build a list of product ID's from the xml response
of an external webservice and then query a Solr instance for description
info about each product ( could be 0 to several hundred individual items ).
Once I have those, I need to push the original message thru XSLT to remap it
to a different tagging structure and insert the product description from the
Solr call into each node group associated with that product ID.
This is a snippet of the xml doc. Most of them are huge and contain nested,
nests of nastiness that will be corrected once it hits the XSLT transform
later on down stream.
Original xml: ( has a node for the description, but does not contain the
data in that system)
<order>
<item>
<id>12345</id>
<desc></desc>
</item>
</order>
Final xml:
<group>
<team>
<sales>
<sku>
<slotnum>12345</slotnum>
<productdesc>This is a fuzzy widget</productdesc>
</sku>
</sales>
</team>
</group>
I have no problems constructing the routes as restlets, working fine. Also
passing the docs to XSLT for remapping is working. Having a huge problem
injecting the descriptions from Solr into the original xml prior to passing
to XSLT.
Can someone show me some code that would most likely run as part of an
aggregation strategy or perhaps a Processor that takes the Solr msg,
extracts the desc using XPath and injects it into the description node?
I looked at JAXB or XStream as possible approaches, but modeling the full
document as an object when I only need to effect one small portion of it
seems like the wrong approach.
Doing my best to figure this out on my own ( very, very small shop ) but
sometimes you just need a little nudge in the right direction.
Thank any and all for their time and expertise.
Zippy
