Split up multiple row payload

Question

Hi guys,
I have the following problem and I am in serious need for some help.
I use JDeveloper 11g and is building a SOA Composite application. The composite uses AQ and I dequeue a message with the following structure:
<payload>
"Test", "Test_2", "20120101", 0
"Test", "Test_3", "20120102", 0
"Test", "Test_4", "20120103", 0
</payload
I.e. every row is comma separated and it could be multiple (n) rows in the payload.
What I want to do with this data is send it to a web service. The trick is that the web service need the separetead values and one row should be send each iteration of the loop.
I.e. the web service want "Test" "Test_2" "20120101" 0 as separate objects on the first iteration and then the next row etc.
My problem is that I do not know how to both loop and split the objects in BPEL (or I do not know how to do any of them).
I would really appreciate some good help, if you suggest any kind of xslt mapping solution - please explain "for dummies" :)

Answer 1

I dont quite understand what you mean by the web service not accepting the request.
I will try to illustrate with an example:
Lets say that the web service that I want to access is http://www.webservicex.net/stockquote.asmx?op=GetQuote. That service only takes one parameter which is the symbol.
Then, lets say that the payload I receive is
<payload>
"GOOG"
"BAC"
"G"
</payload>
I cant send the whole payload at once, hence I need to
1) select the first row
2) send that message
loop back
3) select the second row
4) send that message
etc..
The concept of the above example is what I want to do. (But in my case I have more than one object on each line.) So I would like to know how to single out the objects and send them to the web service and then loop back and do it all again.
Also, for that transform operation. Does that mean that I basically can connect my payload object to that transformation or how is it done?
Edit:
I tried the xsl transformation without success, for some reason I was not able to get to the content of the payload node. Howver, for a more realistic example - this is the object that I will receive:
<?xml version="1.0" encoding="UTF-8" ?>
<?xml-stylesheet type="text/xsl" href="carrierobjectschema.xsl"?> <OBJ_CARRIER_OBJECT>
<SYSTEM xmlns="">xxx</SYSTEM>
<INTERFACENAME xmlns="">yyy</INTERFACENAME>
<INTERFACEOPERATION xmlns="">zzz</INTERFACEOPERATION>
<INTERFACEVERSION xmlns="">1</INTERFACEVERSION>
<PAYLOAD>"111", "222", "333", 0
"112", "223", "334", 0</PAYLOAD>
</OBJ_CARRIER_OBJECT>
And the result I would like (or something similar) is: Note that I am only interested in the payload node.
<obj>
<1>111</1>
<2>222</2>
<3>333</3>
<4>0</4>
</obj>
<obj>
<1>112</1>
<2>223</2>
<3>334</3>
<4>0</4>
</obj>
