cxf-codegen-plugin produces wrong code for wsdl elements with nillable="true"
-----------------------------------------------------------------------------
Key: CXF-3449
URL: https://issues.apache.org/jira/browse/CXF-3449
Project: CXF
Issue Type: Bug
Components: Core, JAXB Databinding
Affects Versions: 2.3.3
Environment: Windows 7 Service Pack 1
Java JDK 1.60_22
Maven 3.01
cxf-codegen-plugin 2.3.3
Reporter: Jens Lauterbach
I think I found a bug in the code generation used/made by CXF. I discovered it
while using the *cxf-codegen-plugin* for Maven. The bug is related to WSDL
elements that use the attribute "nillable" set to "true". I made a little
example which I'll attach to this bug report. In the example there is a
complexType "Message":
{code}
<xsd:complexType name="Message">
<xsd:sequence>
<xsd:element minOccurs="0" name="body" nillable="true" type="xsd:string"/>
</xsd:sequence>
</xsd:complexType>
{code}
Using this complexType the resulting xml output looks like this:
{code}
<?xml version="1.0" ?>
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/";>
<S:Body>
<ns2:SendMessage xmlns:ns2="http://www.example.org/codegenbug/";>
<message>
<ns2:codegenbug>New Message</ns2:codegenbug>
</message>
</ns2:SendMessage>
</S:Body>
</S:Envelope>
{code}
(FYI: _codegenbug_ is the name of the webservice)
If you change the body element in the complexType "Message" to:
{code}<xsd:element minOccurs="0" name="body" type="xsd:string"/>{code}
you get the correct xml output:
{code}
<?xml version="1.0" ?>
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/";>
<S:Body>
<ns2:SendMessage xmlns:ns2="http://www.example.org/codegenbug/";>
<message>
<body>New Message</body>
</message>
</ns2:SendMessage>
</S:Body>
</S:Envelope>
{code}
As you can see in the above example, without *nillable=true* the xml output (or
message) is generated correct.
To test this I created a Maven Project with a test wsdl and a junit test. To
have a look at the xml output I run the query through tcpmon. You can download
tcpmon here:
http://ws.apache.org/commons/tcpmon/download.cgi
In the WSDL I set the endpoint to "http://127.0.0.1:10000";. So you need to make
tcpmon listen on port "10000". The target endpoint is "127.0.0.1" and port
"8088". To quickly create a mockup endpoint I used soapUI. You can download
soupUI here:
http://sourceforge.net/projects/soapui/files/soapui/3.6.1/
I attached the soupUI project to the ticket.
After you set up everything you can run "mvn clean test". You should get a
build failure. But this is ok. There should be a soap message in tcpmon. In
this soap message you can see the faulty xml message.
