Messaging services support (xml messaging services)

[Ken Lee-2]

Hello, I am doing research for currently available open-source
tools/framework to build a e-commerce site for a small business.  Ofbiz
seems to offer a great fit and much more, which is wonderful.

A unique requirement for this project is the product catalog comes from a
data-feed, via xml messaging services over http.   (not quite sure if these
services are based on established standards like soap, most likely not)
Anyway, I did some search in ofbiz's documentations and mailing list, tried
to find existing example/use case for messaging support but couldn't find
anything.  Before I re-invent the wheel, I am wondering if ofbiz already has
any form of supports for xml messaging services where I can use as a
starting point for modification.   If not, what's recommended
approach/practice to implement such service.  Any help or questions would be
greatly appreciated.

it is in here as the responses to xml responses from USP and USPS.
I use http and https from external sources to receive orders in XML format.
I have found it is easier to write the xml to a file than try to process it
immediately. I may receive as many as 95 xml files per sec.
I then have a service that processes the xml files

BJ, my apology if these should be obvious to more experience ones, I am not
very fluent with the ofbiz at this point.  In your reply, it sounds like
ofbiz has services or low level codes that can be config to communicate with
USPS via xml messging? that would be a good starting point if that's the
case.  Thanks for the reply and your advice on processing xml strings, I'll
keep that in mind.

if you look in
OfBiz_home\applications\product\src\org\ofbiz\shipment\thirdparty
you will see the lowlevel code for UPs, USPS, and DHL
I don't use this code, but myown I ported over from a previous application
The USPS is a mock up.

you can find the service defs in
OfBiz_home\applications\product\servicedef

OfBiz_home\applications\product\config\shipment.properties
will give you some of the static config data.

in short in
UspsMockApiServlet
you do a post then do a get for something like interactive communications.
for some that sends to a url, Like a webstore posting a order, or a
supplier posting inventory, you
put a line in the conroller.xml

<!-- these orginate from vendor as Posts -->
     <request-map uri="realtimeorders">
         <security https="true" direct-request="true"/>
         <event type="java"
path="com.businessesnetwork.realtime.vendorTimeEvents" invoke="inventory"/>
         <response name="success" type="view" value="venordorsuccess"/>
         <response name="error" type="view" value="vendorerror"/>
     </request-map>


and the class that has the real time event has a
        public static String inventory(HttpServletRequest request,
                        HttpServletResponse response) {}:
that processes the request.

note if you want the status to show up in the header and show in the
access log use
                response.setHeader("status", "200 OK");//let sender know everything is ok
                response.setStatus(200);//put ok in the access log.

Great, these are excellent info and should be what I am looking for, thank
you BJ.  I'll post some feedback if I find anything that might be useful to
the group.
