DFHPI9027E XML parser error

Technote (troubleshooting)


You are using DFHWS2LS to create a COBOL copybook from a vendor supplied WSDL for an outbound Web service. You receive error message DFHPI9027E The XML parser error has found an error.


DFHPI9027E The XML parser error has found an error: "XSD: Element reference '' is unresolved" at line "296" and column "2319" in document "name.wsdl".


The statement causing the error message is <s:element ref="s:schema" />

Diagnosing the problem

The WSDL was evaluated with the ECLIPSE Validation Tool and it pointed to the line below as being incorrect, just as the DFHPI9027E message stated: line 296 column 19. The <s:element ref="s:schema"/> statement is causing the error:

000294            <s:complexType>
=COLS> ----+----1----+----2----+----3----+----4----+----5
000295              <s:sequence>
000296                <s:element ref="s:schema" /> <-- Bad Line
000297                <s:any />
000298              </s:sequence>
000299            </s:complexType>

The error issued by the Validation Tool reads as follows:

Error resolving component 's:schema'. It was detected that 's:schema' is in namespace '', but components from this namespace are not referenceable from schema document "wsdlname.wsdl". If this is the incorrect namespace, perhaps the prefix of 's:schema' needs to be changed. If this is the correct namespace, then an appropriate 'import' tag should be added to 'wsdlname.wsdl'.

Resolving the problem

You need to replace the <s:element ref="s:schema"/> with an <s:any/> element. If that is done in this WSDL then there would be 2 s:any elements in the same scope and CICS does not support this. However, you can use a minOccurs and maxOccurs to get around this problem, as shown below:

The original XML:

    <s:element ref="s schema  />
    <s:any />

Would be replaced with:

    <s:any maxOccurs="2" minOccurs="2"/>

With MAPPING-LEVEL=2.1 or higher this will be processed by CICS. The application in CICS will receive raw XML in a container that is the content of the s:any elements. The application is responsible for processing the contents of the container.
