Subject [jira] [Commented] (CXF-4113) Header fields duplication in generated wsdl file when using aegis databinding
Date Wed, 15 Feb 2012 16:18:59 GMT


Daniel Kulp commented on CXF-4113:

You should be able to.  In the "More Actions" drop down above, there should be an "Attach

> CXF generates invalid wsdl for jax-ws annotated interfaces when using aegis databinding.

> Problem is in generating schema for methods which have parameters annotated with @WebParam(
name='...', header=true).
> Such parameters are being duplicated in generated wsdl. For example:
> {code}
> ...
>   <xsd:element name="buggyWsdlDef" type="buggyWsdlDef"/>
>   <xsd:complexType name="buggyWsdlDef">
>     <xsd:sequence>
>       <xsd:element minOccurs="0" name="userName" nillable="true" type="xsd:string"/>
>     </xsd:sequence>
>   </xsd:complexType>
>   <xsd:element name="firstHeader" type="xsd:int"/>
>   <xsd:element name="secondHeader" type="xsd:string"/>
>   <xsd:element name="firstHeader" nillable="true" type="xsd:int"/>
>   <xsd:element name="secondHeader" nillable="true" type="xsd:string"/>
>   <xsd:element name="buggyWsdlDefResponse" type="buggyWsdlDefResponse"/>
> ...
> {code}
> This causes some clients totally not to work with such web service(soap ui doesn't complain
> Eclipse wsdl validator gives me this error:
> "A schema cannot contain two global components with the same name; this schema contains
two occurrences of ',firstHeader'.
> My investigation shows that:
> 1. This problem appears only when using aegis databinding.
> 2. This bug presented in versions which are >= 2.4.0 (last version without this bug
is 2.3.9)
> 3. This happens only in wsdl that is being generated for importing through wsdl:import
> In my case original wsdl is <ws-url>/service?wsdl and one that is imported is <ws-url>/service?wsdl=ExampleService.wsdl
> 4. Debugging shows that problem is probably in ReflectionServiceFactoryBean. When service
is starting, next chain of methods is called: buildServiceFromClass->...initializeParameter[many
times]->...initializeWrappedSchema[many times]
> initializeWrappedSchema method calls checkForElement(...) which adds duplications for
header parameters in service object model(ServiceInfo instance).
> Not sure why exactly this happens but hope that it will help you at least locate the
> I'm attaching maven project which demonstrates this problem.
> In order to reproduce this bug using sample project attached:
> 1. "mvn jetty:run" in project directory
> 2. Open localhost:8080/CXFExampleService/service?wsdl=ExampleService.wsdl in the browser
> Search for '<xsd:complexType name="buggyWsdlDef">' occurence in that wsdl.
