REST adapter 12c - DELETE with payload

Naveent_2785

Hi,

Can we invoke a REST resource with a DELETE verb by sending a payload i.e. having representation. When I created a REST reference(using WSDL approach)  by selecting a request schema in the payload for the DELETE method, the below WADL config is created(see 1) , however when I try to send the payload while invoking the rest service the body is going as null.

1) WADL config Default created

<resource path="/cim/{market}/{lang}/v1/{puid}/sms-identity">

         <method name="DELETE" soa:wsdlOperation="CIAM_DeleteSMSIdentity">

            <request soa:paramElement="pns:Request" xmlns:pns="http://ikea/system/ciam/ru/api/CIAM_RU_IntegrationProvABCS_CIAMUnlinkAccount_request">

               <param name="market" style="template" soa:expression="$property.rest.template.market_code" type="xsd:string"/>

               <param name="lang" style="template" soa:expression="$property.rest.template.language_code" type="xsd:string"/>

               <param name="puid" style="template" soa:expression="$property.rest.template.partyUID" type="xsd:string"/>          

            </request>

2) I tried to change the WADL config as below and send a payload but this time it fails with below remote fault while invoking. What is the issue in both the cases.

<resource path="/cim/{market}/{lang}/v1/{puid}/sms-identity">

         <method name="DELETE" soa:wsdlOperation="CIAM_DeleteSMSIdentity">

            <request>

               <param name="market" style="template" soa:expression="$property.rest.template.market_code" type="xsd:string"/>

               <param name="lang" style="template" soa:expression="$property.rest.template.language_code" type="xsd:string"/>

               <param name="puid" style="template" soa:expression="$property.rest.template.partyUID" type="xsd:string"/>

           <representation mediaType="application/json" element="cns:Request" xmlns:cns="http://ikea/system/ciam/ru/api/CIAM_RU_IntegrationProvABCS_CIAMUnlinkAccount_request"/>

            </request>

Hi

Did you get this working?

Hi,

Just seen your query. It seems it is expected behavior of the Jersey Rest Client used internally by the adapter.

As confirmed by Oracle, this is not a bug but due to configuration of JerseyInvocation class, which validate request body for all HTTP methods. In case of DELETE method, is marked as MUST_BE_NULL. Even they confirmed SOA version upgrade will not help with this issue.

I think it is standard of not allowing entities in the DELETE HTTP Method invocation.

map.put("DELETE", EntityPresence.MUST_BE_NULL);

So, possible options I can think of are instead of using a REST adapter, create a java class(spring rest) and use that to invoke as a spring component in your BPEL process.
