Wsimport error while parsing WSDL

Question

I need to consume a SOAP WebService in my application, so I got the WSDL file to generate the needed classes with help of wsimport. The problem is that during parsing I get the following error:

[ERROR] invalid extension element: "soap:body" (in namespace "http://schemas.xmlsoap.org/wsdl/soap/")

I tried the -extension flag but without success.

Has anyone ran into a similar problem in the past? And if yes, how did you solve it?

I'm on my phone now, so here is the link ws.e-podroznik.pl/?wsdl — wookie
Here's a simpler WSDL that exhibits the same problem: gist.github.com/thobbs/4ebd192dacf064d324ad6a05828ced96 — Tyler Hobbs

Not sure if this is the whole fault...

Trying wsimport against that simpler WSDL returned:

[ERROR] invalid extension element: "soap:header" (in namespace "http://schemas.xmlsoap.org/wsdl/soap/")

The error message doesn't give the location, but the problem is the <soap:header> and <soap:body> under the parent <fault>:

<fault name="Error">
    <soap:header message="sm:GetSeatMapCountsErrorOutput" part="header" use="literal"/>
    <soap:header message="sm:GetSeatMapCountsErrorOutput" part="header2" use="literal"/>
    <soap:body parts="body" use="literal" />
</fault>

Typically this would be something more like:

<fault name="Error">
    <soap:fault name="Error" use="literal" /> 
</fault>

It looks like this is correct in the link in the earlier comment (http://ws.e-podroznik.pl/?wsdl). Perhaps this has been fixed since?

To get a clue as to where the invalid <soap:header> is in the message, one trick is to use wsimport -Xdebug, which will include a stack trace for the exception in the output:

Caused by: com.sun.tools.ws.wsdl.framework.ParseException: invalid extension element: "soap:header" (in namespace "http://schemas.xmlsoap.org/wsdl/soap/")
    at com.sun.tools.ws.wsdl.parser.Util.fail(Util.java:186)
    at com.sun.tools.ws.wsdl.parser.SOAPExtensionHandler.handleFaultExtension(SOAPExtensionHandler.java:413)
    at com.sun.tools.ws.api.wsdl.TWSDLExtensionHandler.doHandleExtension(TWSDLExtensionHandler.java:87)

The clue in there is the SOAPExtensionHandler.handleFaultExtension(), which indicates the problem is under the parent <fault> element.

Similarly it could have been handleBindingExtension() under <binding>, handleOperationExtension() under <operation>, etc.
