AssertionError when providing both empty type definition and globalBinding to wsdl2java

[Matti Bickel <mb...@demandware.com>]

Hi,

I've got a problem trying to generate a Java webservice out of a WSDL file I got from a 3rd party. It boils down to these test-case:

test.wsdl:
<?xml version="1.0"?>
<definitions name="StockQuote"
             targetNamespace="http://example.com/stockquote.wsdl"
             xmlns:tns="http://example.com/stockquote.wsdl"
             xmlns:xsd='http://www.w3.org/2001/XMLSchema'
             xmlns:xsd1="http://example.com/stockquote.xsd"
             xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"
             xmlns="http://schemas.xmlsoap.org/wsdl/">
  <types>
  </types>

  <message name="GetLastTradePriceInput">
    <part name="body" type="xsd:string"/>
  </message>

  <message name="GetLastTradePriceOutput">
    <part name="body" type="xsd:string"/>
  </message>

  <portType name="StockQuotePortType">
    <operation name="GetLastTradePrice">
      <input message="tns:GetLastTradePriceInput"/>
      <output message="tns:GetLastTradePriceOutput"/>
    </operation>
  </portType>

  <binding name="StockQuoteSoapBinding" type="tns:StockQuotePortType">
    <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>
    <operation name="GetLastTradePrice">
      <soap:operation soapAction="http://example.com/GetLastTradePrice"/>
      <input>
        <soap:body use="literal"/>
      </input>
      <output>
        <soap:body use="literal"/>
      </output>
    </operation>
  </binding>

  <service name="StockQuoteService">
    <documentation>My first service</documentation>
    <port name="StockQuotePort" binding="tns:StockQuoteSoapBinding">
      <soap:address location="http://example.com/stockquote"/>
    </port>
  </service>
</definitions>

jaxb_bindings.xml:
<?xml version="1.0" encoding="UTF-8"?>
<jaxb:bindings version="2.0" xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
xmlns:ext="http://xml.w-wins.com/xjc-plugins/interfaces"
    jaxb:extensionBindingPrefixes="xjc">

    <jaxb:globalBindings generateElementProperty="false" choiceContentProperty="true" typesafeEnumMaxMembers="1500">
    </jaxb:globalBindings>
</jaxb:bindings>

Now, when I run wsdl2java like this:
​mbickel@neptun ~ $ apache-cxf-2.7.17/bin/wsdl2java -b ./jaxb_bindings.xml -d /tmp -compile -autoNameResolution -frontend jaxws21 ./test.wsdl

I get this output:

at org.apache.cxf.tools.wsdlto.WSDLToJava.main(WSDLToJava.java:184)

Which apparently is caused by DOMForest not including the empty <types></types> definition, so the Internalizer doesn't have anyplace to move the global bindings.
I can work-around this by not providing a jaxb:globalBindings or providing a (useless) type definition in the wsdl.

Now the question is: is this something CXF can work-around for me or even a bug that can be fixed?

Thanks, Matti
