Java Example With Cxf Web Services ~ Runtime Exception

Question

I'm trying to create client with apache-cxf.
I need to run following web service http://soapclient.com/xml/soapresponder.wsdl
What i'm trying to achieve is i will give two parameters to this service and return result/response.

Here is my code below:

JaxWsDynamicClientFactory dfc = JaxWsDynamicClientFactory.newInstance();
Client client = dfc.createClient("http://soapclient.com/xml/soapresponder.wsdl");

Object res[] = client.invoke("echo", "test echo");
System.out.println("Result: " + res[0]);

I'm getting lots of error such as:

Exception in thread "main" java.lang.RuntimeException: Fatal error compiling schema from WSDL at {http://soapclient.com/xml/soapresponder.wsdl}: Unexpected <schema> appears at line 9 column 5

It's failing because the WSDL that's published at that address is invalid. The specific point of failure that CXF is complaining about is this:

<types>
    <schema xmlns="http://www.w3.org/1999/XMLSchema" targetNamespace="http://www.SoapClient.com/xml/SoapResponder.xsd"></schema>
</types>

Notice the unqualified use of the <schema> tag? That tag is provided within the http://www.w3.org/2001/XMLSchema namespace, qualified with the prefix xsd. What should be in the WSDL is:

<types>
    <xsd:schema xmlns="http://www.w3.org/1999/XMLSchema" targetNamespace="http://www.SoapClient.com/xml/SoapResponder.xsd"></xsd:schema>
</types>

Why it turned out incorrectly is beyond me; afterall, the namespace and the prefix are properly declared at the top in the wsdl:

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

To resolve, save a local copy of that wsdl, make an edit to correct the unqualified tag use, and then use the corrected local copy in your application
