"XML-24500: (Error) Can not build schema" in JDeveloper 11g

Problem:

We migrated an ESB 10g project to Mediator 11g. What is strange is that this project works completely fine in the 10g world. However, when we try to make or deploy it in JDeveloper 11g, we receive the following error:
Investigation:

Oracle JDeveloper 10g is more liberal in its verification. In fact, our problem was the following.
  • Our JDeveloper 11g composite looks like this:
  • There are 2 external SOAP services, each having its own WSDL. For example:
http://external.ipnweb.org/Location/AddressWebService.svc?wsdl
http://external.ipnweb.org/Contact/ContactWebService.svc?wsdl
  • Observe the schema definition in each of the WSDLs. You will notice that the same namespace is used across both references, but related to different XSDs.
First WSDL
<xsd:schema targetNamespace="http://ns.ipnweb.com/MyApp/AddressWebService/20090101/Imports">
  <xsd:import schemaLocation="http://external.ipnweb.org/Location/AddressWebService.xsd" namespace="http://ns.ipnweb.com/MyApp/Contact/20090101"/>
  <xsd:import schemaLocation="http://external.ipnweb.org/Location/AddressWebService.xsd" namespace="http://ns.ipnweb.com/MyApp/AuditableDomainBase/20090101"/>
</xsd:schema>

Second WSDL
<xsd:schema targetNamespace="http://ns.ipnweb.com/MyApp/ContactWebService/20090101/Imports">
  <xsd:import schemaLocation="http://external.ipnweb.org/Contact/ContactWebService.xsd" namespace="http://ns.ipnweb.com/MyApp/Contact/20090101"/>
  <xsd:import schemaLocation="http://external.ipnweb.org/Contact/ContactWebService.xsd" namespace="http://ns.ipnweb.com/MyApp/Enums/20090101"/>
</xsd:schema>
  • When we open both the XSDs, we can see that the same element is defined identically, but the problem is, the annotations are defined in one of them, but not the other.
First XSD
<xs:complexType name="Organization">
  <xs:complexContent mixed="false">
    <xs:extension base="q1:DomainBase">
      <xs:sequence>
        <xs:element minOccurs="0" name="OrgId" nillable="true" type="xs:string"/>
      </xs:sequence>
    </xs:extension>
  </xs:complexContent>

Second XSD
<xs:complexType name="Organization">
  <xs:annotation>
    <xs:appinfo>
      <Surrogate i:type="d1p1:Annotation"/>
    </xs:appinfo>
  </xs:annotation>
  <xs:complexContent mixed="false">
    <xs:extension base="q1:DomainBase">
      <xs:sequence>
        <xs:element minOccurs="0" name="OrgId" nillable="true" type="xs:string">
          <xs:annotation>
            <xs:appinfo>
              <Surrogate i:type="d1p1:Annotation"/>
            </xs:appinfo>
          </xs:annotation>
        </xs:element>
      </xs:sequence>
    </xs:extension>
  </xs:complexContent>
The fact that the annotations are different is what is causing the XML-24500 error seen above.

Resolution:

Ensure that the XSDs are identical in terms of definition, including annotations.
