Generating stubs with jax-ws fails

Question

I am trying to generate a stub using jax-ws for the WSO2 Identity Server admin service https://xx.xx.xx.xx:9447/services/RemoteUserStoreManagerService?wsdl.

I've downloaded the wsdl but when I run:

wsimport -p org.wso2 RemoteUserStoreManagerService.xml

I get the following errors

        Failed to parse the WSDL.

Here's the wsdl schema around line 679 of the file where the first error appears (not posting the whole schema, because it's rather large):

       <wsdl:operation name="updateCredential">
        <wsdl:input message="ns:updateCredentialRequest" wsaw:Action="urn:updateCredential"/>
        <wsdl:fault message="ns:RemoteUserStoreManagerServiceUserStoreException" name="RemoteUserStoreManagerServiceUserStoreException" wsaw:Action="urn:updateCredentialRemoteUserStoreManagerServiceUserStoreException"/>
    </wsdl:operation>
    <wsdl:operation name="setUserClaimValue">
        <wsdl:input message="ns:setUserClaimValueRequest" wsaw:Action="urn:setUserClaimValue"/>
        <wsdl:fault message="ns:RemoteUserStoreManagerServiceUserStoreException" name="RemoteUserStoreManagerServiceUserStoreException" wsaw:Action="urn:setUserClaimValueRemoteUserStoreManagerServiceUserStoreException"/>
    </wsdl:operation>
    <wsdl:operation name="getUserClaimValuesForClaims">
        <wsdl:input message="ns:getUserClaimValuesForClaimsRequest" wsaw:Action="urn:getUserClaimValuesForClaims"/>
        <wsdl:output message="ns:getUserClaimValuesForClaimsResponse" wsaw:Action="urn:getUserClaimValuesForClaimsResponse"/>
        <wsdl:fault message="ns:RemoteUserStoreManagerServiceUserStoreException" name="RemoteUserStoreManagerServiceUserStoreException" wsaw:Action="urn:getUserClaimValuesForClaimsRemoteUserStoreManagerServiceUserStoreException"/>
    </wsdl:operation>

Answer 1

Try adding output message in all wsdl operations. It is interesting to notice that wsimport doesn't complain on getUserClaimValuesForClaims operation, and that method has output message defined.

EDIT: You can edit wsdl without fear because these problematic methods have void return type so you can put whatever you want as a return type and simply ignore it. In other words, when calling Web service you are only interested in the input parameters since these methods actually don't return anything. Therefore, do the following:

1. Make a copy of wsdl, for example name it client.wsdl
2. Add output message to all operations which don't have it
3. Generate a Web service client from client.wsdl (don't change the service!)
4. Call Web service methods and ignore the return type for these "problematic" ones

Answer 2

Miljen Mikic's answer was excellent and got me to the right solution. I thought I would give an example of how to do what he suggested. Notice from the error list that the errors come in pairs:

[ERROR] operation "updateCredential" has an invalid style
line 679 of file:/C:/tmp/RemoteUserStoreManagerService.xml
.
.
.
[ERROR] operation "updateCredential" has an invalid style
line 1205 of file:/C:/tmp/RemoteUserStoreManagerService.xml
.
.
.

The OP's wsdl sample only included the first 2 errors, but the solution is similar for all. The result becomes:

<wsdl:operation name="updateCredential">
    <wsdl:input message="ns:updateCredentialRequest" wsaw:Action="urn:updateCredential"/>
    <wsdl:output message="" />
    <wsdl:fault message="ns:RemoteUserStoreManagerServiceUserStoreException" name="RemoteUserStoreManagerServiceUserStoreException" wsaw:Action="urn:updateCredentialRemoteUserStoreManagerServiceUserStoreException"/>
</wsdl:operation>
<wsdl:operation name="setUserClaimValue">
    <wsdl:input message="ns:setUserClaimValueRequest" wsaw:Action="urn:setUserClaimValue"/>
    <wsdl:output message="" />
    <wsdl:fault message="ns:RemoteUserStoreManagerServiceUserStoreException" name="RemoteUserStoreManagerServiceUserStoreException" wsaw:Action="urn:setUserClaimValueRemoteUserStoreManagerServiceUserStoreException"/>
</wsdl:operation>
