Re: wsdl2java generated code doesn't handle boolean correctly?

Hey Ege,
The JAXB comment snippet looks fine. Because PersonInformationProtected type comes from standard XML Schema it can miss namespace prefix. Since I haven't worked with JAXB for long time my assumptions here might be wrong. 


Have you tried to create a small JAXB generator and reader to see what 
kind of output you will get from that bean alone?
If you can prove that it codegen output works with JAXB alone then its 
probably issue for CXF, if its still fails with JAXB then it might be 
code generator or XJC bug.
If basic xml reader/writer will break you can try adjusting JAXB 
versions in order to see if any version around work. Main point to 
remember - XML is assembled back based on annotations and ObjectFactory 
classes passed to marshaller. You can try tweaking manually generated 
classes to see how it will impact output. Maybe schema declaration in 
@JAXBElement annotation namespace is missing for 
PersonInformationProtected field?


Best,
Łukasz

Hello

Thank you for taking the time to have a look at this:

I have followed the link you provided, and I have had a look at some of the 
tools. I really need some documentation in order to use them. I manage to start 
one of them (C# tool) and it failed two tests, but none specific to this field 
(but was related to the class the field was in). But again, I don't really know 
if I tested for the right stuff.

I checked the WSDL using SOAP-UI and it found no faults.

I also used wsdl-analyzer.com and it also found no problems.

I checked the WSDL using wsimport from Metro jaxws 4.0.0 and it claimed there 
was 5 errors (1 not being able to look up q1:PersonInformationDTO, and 4 
regarding the faults having namespace assigned).

I then generated the java files anew using cxf wsdl2java but used the -validate 
flag, yet no warnings/errors were shown. In the PersonInformationDTO.class file 
there is this comment:

/**
  * <p>Java class for PersonInformationDTO complex type.
  *
  * <p>The following schema fragment specifies the expected content contained 
within this class.
  *
  * <pre>
  * &lt;complexType name="PersonInformationDTO"&gt;
  *   &lt;complexContent&gt;
  *     &lt;restriction base="{http://www.w3.org/2001/XMLSchema}anyType"&gt;
  *       &lt;sequence&gt;
  *         &lt;element name="GeneralPractitioner" 
type="{http://schemas.datacontract.org/2004/07/CGM.DGWS.SSNLookup.Service.Models}GeneralPractitionerDTO"; 
minOccurs="0"/&gt;
  *         &lt;element name="PersonInformationProtected" 
type="{http://www.w3.org/2001/XMLSchema}boolean"; minOccurs="0"/&gt;
  *         &lt;element name="PersonName" 
type="{http://schemas.datacontract.org/2004/07/CGM.DGWS.SSNLookup.Service.Models}PersonNameDTO"; 
minOccurs="0"/&gt;
  *         &lt;element name="PostalAddress" 
type="{http://schemas.datacontract.org/2004/07/CGM.DGWS.SSNLookup.Service.Models}PostalAddressDTO"; 
minOccurs="0"/&gt;
  *         &lt;element name="PublicHealthInsurance" 
type="{http://schemas.datacontract.org/2004/07/CGM.DGWS.SSNLookup.Service.Models}PublicHealthInsuranceDTO"; 
minOccurs="0"/&gt;
  *         &lt;element name="SocialSecurityNumber" 
type="{http://www.w3.org/2001/XMLSchema}string"; minOccurs="0"/&gt;
  *       &lt;/sequence&gt;
  *     &lt;/restriction&gt;
  *   &lt;/complexContent&gt;
  * &lt;/complexType&gt;
  * </pre>
  *

  */

The point here is that wsdl2java clearly knows about the Boolean and the 
correct schema for it.

I'll try to look further in to the validators you linked and hope to figure out 
which one to use and how to set it up.

Thank you,

Bernhard

Hello Ege,
The ObjectFactory class which is generated out of schema includes complex types 
such as PersonInformationDTO, PersonNameDTO and so on.
All types which are of scalar (boolean, int, ...) and derivative (simple 
content, scalar type extensions) will be ommited as they are mapped to 
aproprieate Java types which are part of Java standard library.

You can find in generated code you pasted:
protected Boolean personInformationProtected

This is scalar value coming out of xs:boolean type defined in schema.
To me it looks like schema processing or JAXB runtime misses namespace information. 
Error you pasted indicate *<{}PersonInformationProtected>* which does not 
include namespace.
Can you confirm if service you work with is compatible with WS-I Basic Profile? You can use 
publicly available tools from Web Services Interopability Organization:
