-----------------------------
Component/s: Soap Binding
> Dealing with empty soap:body together with MIME-Attachment in wsdl
> ------------------------------------------------------------------
>
> Key: CXF-6937
> URL: https://issues.apache.org/jira/browse/CXF-6937
> Project: CXF
> Issue Type: Bug
> Components: Soap Binding
> Affects Versions: 3.1.6
> Environment: Windows 7, Java 1.8_74
> Reporter: Stefan Laube
> Priority: Minor
>
> There are problems validating a wsdl and generating java-stubs from wsdl when the wsdl-file contains an empty soap:body-definition while data is put to MIME-Attachment.
> In a wsdl-file, i need to specify an empty soap:body, while the <message>-specific data needs to go to header and/ or attachment.
> As far as i know, an empty soap:body is defined with:
> {{<soap:body parts=""/>}}
> This construct is used in two cases in the following showcase in line 61 and line 71.

> {code}
> In the wsdl:input-definition (line 57ff.), the message-part "Version" is put into soap:header, as mentioned no part shall be put into soap:body and the "DataReq"-part is put into attachment.
> In the wsdl:output-definition (line 68ff.), again, nothing shall be put into soap:body while the "DataRsp"-part is put into attachment.
> Now, when i validate this wsdl-file using the command line:
> {{apache-cxf-3.1.6\bin\wsdlvalidator.bat showcase.wsdl}}
> i get multiple error messages, basically saying:
> {{cvc-minLength-valid: Value '' with length = '0' is not facet-valid with respect to minLength '1' for type 'NMTOKENS'.}}
> {{cvc-attribute.3: The value '' of attribute 'parts' on element 'soap:body' is not valid with respect to its type, 'NMTOKENS'}}
> As far as i understand these output, it is not allowed to define an empty "parts"-element, thus no empty soap:body.
> *But why?*
> Now when i generate java-stubs from this wsdl-file, using the command line:
> {{apache-cxf-3.1.6\bin\wsdl2java.bat" -verbose -d java_out showcase.wsdl}}
> the resulting files seem to be ok (generated interfaces and classes can be implemented/ extended) but during stub-generation i get the message:
> {{INFORMATION: Operation \{http://showcase.de/v1}MyFunc cannot be unwrapped, input and output messages (if present) must contain only a single part}}
> which i don't know how to interpret. For me, it seems to be connected to the error-messages during validation.
> *Can this be ignored?* *Is anything left out in the generated stubs?*
> Interestingly i get no such messages when generating the java-stubs using the ant-task "com.sun.tools.ws.ant.WsImport" (having verbose=true).
> Any clarification is appreciated.
