------------------------------------

             Summary: Incorrect code generated with wadl2java tool when use 
JAXB binding and XML symple type with restriccion.
                 Key: CXF-4292
                 URL: https://issues.apache.org/jira/browse/CXF-4292
             Project: CXF
          Issue Type: Bug
            Reporter: Zebensui Méndez
         Attachments: cxf_2_6_0_wadl.zip


If we have an XML schema with a simpleType that has a restriction, the tool is 
not able to determine the basic type of java.


Example:

    <xs:simpleType name="DetailType">
        <xs:annotation>
            <xs:documentation>DetailType for WADL is used to indicate the 
possible values for a WADL Resource parameter. 
                This parameter specifies the desired amount of information to 
be returned. 
                For example, it is possible to instruct the web service to 
return only basic information about the maintainable artefact (i.e.: id, agency 
id, version and name). 
                Most notably, items of item schemes will not be returned (for 
example, it will not return the codes in a code list query). 
                Possible values are: "allstubs" (all artefacts should be 
returned as stubs ), "referencestubs" (referenced artefacts should be returned 
as stubs ) 
                and full (all available information for all artefacts should be 
returned ).
            </xs:documentation>
        </xs:annotation>
        <xs:restriction base="xs:string">
            <xs:pattern value="allstubs"/>
            <xs:pattern value="referencestubs"/>
            <xs:pattern value="full"/>
        </xs:restriction>
    </xs:simpleType>



And the generated code is:

@Path("datastructure/{agencyID}/{resourceID}/{version}")
public interface Datastructure {

    @GET
    @Produces("application/vnd.sdmx.structure+xml;version=2.1")
    StructureType MaintainableArtefactQuery(@QueryParam("detail") 
@DefaultValue("full") DetailType detail, @QueryParam("references") 
@DefaultValue("none") ReferencesType references);

}

But DetailType doen't have JAXB binding because is a simpleType (a String). The 
the correct code would be:

@Path("datastructure/{agencyID}/{resourceID}/{version}")
public interface Datastructure {

    @GET
    @Produces("application/vnd.sdmx.structure+xml;version=2.1")
    StructureType MaintainableArtefactQuery(@QueryParam("detail") 
@DefaultValue("full") String detail, @QueryParam("references") 
@DefaultValue("none") ReferencesType references);

}

Please run the attached code (mvn generate-sources with java parameters 
-Xms512M -Xmx1024M) to reproduce the issue. Then see for example the class 
"Datastructure".
