I am invoking a business service from OSB 12C that accepts POST methods. I added a REST adapter in the business column after making the request and response XSD's. In the pipeline, I use an XQuery file for transformation of the proxy service's request body to the business service's body.
Examining the receiving app as well as the network traffic, I see that the request is being submitted with a Content-Type: application/x-www-form-urlencoded header, but the payload is completely blank.
As a test, I changed the method to GET. This places the form fields within the URL, so the transformation, etc. is correct. It just doesn't work in the POST method. I've been stuck for a week on this.
Here's the XSD for the business request:
<?xml version = '1.0' encoding = 'UTF-8'?>
<xsd:schema

targetNamespace="http://TargetNamespace.com/SmartCardBusiness_GetPendingRequests_request"
elementFormDefault="qualified" attributeFormDefault="unqualified" nxsd:encoding="US-ASCII">
<xsd:element name="GetPendingRequests-BusinessRequest-Root-Element">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="db" type="xsd:string"/>
<xsd:element name="fromDate" type="xsd:string"/>
<xsd:element name="max" type="xsd:integer"/>
<xsd:element name="page" type="xsd:integer"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
<xsd:annotation>
<xsd:appinfo>NXSDSAMPLE=</xsd:appinfo>
<xsd:appinfo>USEHEADER=false</xsd:appinfo>
</xsd:annotation>
</xsd:schema>
And the XQuery file:
xquery version "1.0" encoding "utf-8";
(:: OracleAnnotationVersion "1.0" ::)
declare namespace smar="http://TargetNamespace.com/SmartCardBusiness_GetPendingRequests_request";
(:: import schema at "GetPendingRequestsBusinessRequest.xsd" ::)
declare variable $db as xs:string external;
declare variable $fromDate as xs:string external;
declare variable $max as xs:integer external;
declare variable $page as xs:integer external;
declare function local:func($db as xs:string, $fromDate as xs:string, $max as xs:integer, $page as xs:integer) as element()
(:: schema-element(smar:GetPendingRequests-BusinessRequest-Root-Element) ::) {
<smar:GetPendingRequests-BusinessRequest-Root-Element
xmlns:smar="http://TargetNamespace.com/SmartCardBusiness_GetPendingRequests_request">
<smar:db>{fn:data($db)}</smar:db>

<smar:max>{fn:data($max)}</smar:max>
<smar:page>{fn:data($page)}</smar:page>
</smar:GetPendingRequests-BusinessRequest-Root-Element>
};
local:func($db, $fromDate, $max, $page)
