WSDL Import for External Definiton

Question

Hi,
I'm trying to import a wsdl document in order to create an external definition for a WS I am wishing to envoke from XI.
However I get the following error:
Cause: Unable to recognize the loaded document as valid WSDL  The value "xsd:schema" is not permitted for the attribute "ref" of the "QName" type in the "/schema/element("Browse_DataSetResponse")/complexType/sequence/element("Browse_DataSetResult")/complexType/sequence/element("http://www.w3.org/2001/XMLSchema:schema")" element
followed by more errors relating to the value xsd:schema being used. 
However I have successfully used this wsdl before and it is from a commercial service so syntactically should be correct.
Can anybody help please. 
Thanks in advance
John

Hi Jhon,
There are two ways of defining an XSD (or WSDL). Depending the complexity, while importing an WSDL file, XI will not recognise the file as valid and throws errors. It might look a vague answer, but true, because I have faced similar problem in the past. There is a work around as follows. From your description I could understand, your WSDL is equivalent to File 1. Redefine your WSDL so that it doesn't contain any refernce types.
The File 1 & 2 below defines the same XML content but they way do is different. The first one uses a 'Type and Refence Linkage' where as the second one uses 'Direct Linkage'. Redefine your file as in 2 and import, it would work.
File 1:
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified">
<xsd:element name="Root">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="Child" maxOccurs="unbounded">
<xsd:complexType>
<xsd:sequence>
<xsd:attribute name="Name" type="xsd:string"/>
<xsd:attribute name="Mobile" type="xsd:string"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:sequence>
</xsd:complexType>
</xsd:elemet>
</xsd:schema>
File 2:
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified">
<xsd:element name="Root">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="Child" type="Type" maxOccurs="unbounded"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
<xsd:complexType name="Type">
<xsd:attribute name="Name" type="xs:string"/>
<xsd:attribute name="Mobile" type="xs:string"/>
</xsd:complexType >
</xsd:schema>
Hope it would help you.
