JavaToWS generating non-working WSDL
------------------------------------
Key: CXF-4089
URL: https://issues.apache.org/jira/browse/CXF-4089
Project: CXF
Issue Type: Bug
Affects Versions: 2.4.6, 2.4.5, 2.4.4, 2.4.3
Environment: N/A
Reporter: Pranab Mehta
I use JavaToWS to generate the WSDL on my development box. After migrating to
2.4.3 (from 2.4.1) I noticed that the WSDL being generated is slightly
different (uses references). And any clients generated using wsdl2java, on that
WSDL do not work. This issue is easily reproducible.
The data object in question is, lets say, a Widget, and the SOAP API call is
getWidget(). Here is what Widget looks like:
<code>
@XmlRootElement(name = "Widget")
@XmlAccessorType(XmlAccessType.PROPERTY)
@XmlType(name = "Widget")
public class Widget {
private FOO foo;
private Bar bar;
public FOO getFOO() {
return foo;
}
public void setFOO(FOO foo) {
this.foo = foo;
}
public Bar getBar() {
return bar;
}
public void setBar(Bar bar) {
this.bar = bar;
}
}
</code>
The WSDL generated by JavaToWS looks like this:
<wsdl>
<xs:complexType name="Widget">
<xs:sequence>
<xs:element minOccurs="0" name="bar" type="tns:Bar"/>
<xs:element minOccurs="0" ref="tns:FOO"/>
</xs:sequence>
</xs:complexType>
</wsdl>
Notice how bar is explicitly listed inline, but FOO is referred to via a
reference. Both bar and FOO have the exact same annotations. In CXF 2.4.1, both
of these elements would be explicitly listed inline.
And the generated code using wsdl2java looks like this:
<code>
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "Widget", propOrder = { "bar", "foo" })
public class Widget {
protected Bar bar;
@XmlElement(name = "FOO", namespace = "http://example.com/";)
protected FOO foo;
<SNIP>
}
</code>
Notice, that FOO is explicitly marked to be in a namespace in the generated
code, and bar is in no explicit namespace.
Now, when we call the getWidget() on the web service, we get back:
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/";>
<soap:Body>
<ns2:getWidgetResponse xmlns:ns2="http://example.com/";>
<return>
<bar>
<intBar>7</intBar>
</bar>
<FOO>
<fooInt>99</fooInt>
</FOO>
</return>
</ns2:getWidgetResponse>
</soap:Body>
</soap:Envelope>
And CXF throws the exception:
org.apache.cxf.phase.PhaseInterceptorChain doDefaultLogging
WARNING: Interceptor for
{http://example.com/}FooWebService#{http://example.com/}getWidget has thrown
exception, unwinding now
org.apache.cxf.interceptor.Fault: Unmarshalling Error: unexpected element
(uri:"", local:"FOO"). Expected elements are <{http://example.com/}FOO>,<{}bar>
The CXF client is expecting FOO to be in the namespace http://example.com, but
JAXB does not namespace elements. Hence the exception. bar is unmarshalled just
fine. Now this worked fine in when we used JavaToWS in 2.4.1 and is broke now.
Note I have done some more testing, and 2.4.2 is fine, but 2.4.3 onwards is
broke. I switched out the CXF 2.4.3 to use CXF 2.4.1's JAXB jars, and the
problem still exists.
The bug is easily reproducible - but I can add sample code if required.
