Hello!

I use SOA Suite 11g.

1. Composite has component

  <component name="ClientPrepare" version="2.0">

    <implementation.bpel src="ClientPrepare.bpel"/>

    <property name="bpel.config.oneWayDeliveryPolicy" type="xs:string"

              many="false">async.persist</property>

  </component>

and reference (rest service, get method)

  <reference name="PrepareService"

             ui:wsdlLocation="PrepareService.wsdl">

    <interface.wsdl interface="http://xmlns.oracle.com/pcbpel/adapter/http/ClientPrepare/PrepareService#wsdl.interface(ClientPrepare_ptt)"/>

    <binding.ws port="ns#wsdl.endpoint(srv/prt)"

                location="PrepareService.wsdl" supports="http">

      <property name="http.verb" type="xs:string" many="false">GET</property>

      <property name="endpointURI" type="xs:string" many="false">"<some url>"</property>

      <property name="http.payload" type="xs:string" many="false">url-encoded</property>

      <property name="oracle.webservices.http.invocation" type="xs:string" many="false">false</property>

    </binding.ws>

  </reference>

2. When component invokes rest service, it receives success http 200, but component process has fault

Unable to invoke endpoint URI "<some url>" successfully due to: javax.xml.soap.SOAPException: Unable to read response: org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 1; Premature end of file.

3. Rest Service receives http header only, without content:

HTTP/1.1 200 OK

Date: Tue, 14 Jan 2020 09:03:24 GMT

rlog_pk: 10005254841979

Content-Type: text/html;charset=windows-1251

Content-Language: en

Connection: Keep-Alive

Keep-Alive: timeout=5, max=999

Server: Oracle-Fusion-Middleware/11g (11.1.1.9) Apache-Coyote/1.1 Oracle-Web-Cache-11g/11.1.1.9.0 (N;ecid=733173134358256,0:1)

Content-Length: 0

4. Rest Service response is:

<html><head></head><body></body></html>

Could you please tell me, what should I do for solving?

    I added to reference in composite.xml follow property

    <property name="oracle.soa.two.way.ssl.enabled" type="xs:boolean" many="false" override="may">true</property>

      <reference name="PrepareService"

                 ui:wsdlLocation="PrepareService.wsdl">

        <interface.wsdl interface="http://xmlns.oracle.com/pcbpel/adapter/http/ClientPrepare/PrepareService#wsdl.interface(ClientPrepare_ptt)"/>

        <binding.ws port="ns#wsdl.endpoint(srv/prt)"

                    location="PrepareService.wsdl" supports="http">

          <property name="http.verb" type="xs:string" many="false">GET</property>

          <property name="endpointURI" type="xs:string" many="false">"<some url>"</property>

          <property name="http.payload" type="xs:string" many="false">url-encoded</property>

          <property name="oracle.soa.two.way.ssl.enabled" type="xs:boolean" many="false" override="may">true</property>

          <property name="oracle.webservices.http.invocation" type="xs:string" many="false">false</property>

        </binding.ws>

      </reference>

    I guess one of the problem is content

    Content-Type: text/html

    from http header of response. Because process waits xml content.

    I guess I should modify wsdl for reference PrepareService with type=text/html , to like that:

    <?xml version="1.0" encoding="UTF-8"?>

    <wsdl:definitions name="ClientPrepareService"

                      targetNamespace="http://xmlns.oracle.com/pcbpel/adapter/http/ClientPrepare/ClientPrepare/ClientPrepareService"

                      xmlns:tns="http://xmlns.oracle.com/pcbpel/adapter/http/ClientPrepare/ClientPrepare/ClientPrepareService"

                      xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"

                      xmlns:mime="http://schemas.xmlsoap.org/wsdl/mime/"

                      xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"

                      xmlns:xsd="http://www.w3.org/2001/XMLSchema"

                      xmlns:msg_in_out="http://ClientPrepareService/http"

                      xmlns:plt="http://schemas.xmlsoap.org/ws/2003/05/partner-link/">

        <plt:partnerLinkType name="ClientPrepare_plt">

            <plt:role name="ClientPrepare_role">

                <plt:portType name="tns:ClientPrepare_ptt"/>

            </plt:role>

        </plt:partnerLinkType>

        <wsdl:types>

            <schema xmlns="http://www.w3.org/2001/XMLSchema">

                <import namespace="http://ClientPrepareService/http"

                        schemaLocation="xsd/ClientPrepareService.xsd"/>

            </schema>

        </wsdl:types>

        <wsdl:message name="req_msg_in">

            <wsdl:part name="req" element="msg_in_out:req"/>

        </wsdl:message>

        <wsdl:message name="res_msg_in">

            <wsdl:part name="res" type="xsd:string"/>

        </wsdl:message>

        <wsdl:portType name="ClientPrepare_ptt">

            <wsdl:operation name="ClientPrepareOperation">

                <wsdl:input message="tns:req_msg_in"/>

                <wsdl:output message="tns:res_msg_in"/>

            </wsdl:operation>

        </wsdl:portType>

        <wsdl:binding name="ClientPrepare_Binding"

                      type="tns:ClientPrepare_ptt">

            <soap:binding transport="http://schemas.xmlsoap.org/soap/http"/>

            <wsdl:operation name="ClientPrepareOperation">

                <soap:operation soapAction="http://xmlns.oracle.com/pcbpel/adapter/http/ClientPrepare/ClientPrepare/ClientPrepareService/ClientPrepareOperation"

                                style="document"/>

                <wsdl:input>

                    <soap:body use="literal"/>

                </wsdl:input>

                <wsdl:output>

                    <mime:multipartRelated>

                        <mime:part>

                            <mime:content part="res" type="text/html"/>

                        </mime:part>

                    </mime:multipartRelated>

                </wsdl:output>

            </wsdl:operation>

        </wsdl:binding>

    </wsdl:definitions>

    But when I try recreate HTTP Binding Adapter in composite, at 5th step Reply Message Schema is not recognized.
