[jira] [Resolved] (CXF-6747) XSD to Java problem with enums

["Daniel Kulp (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/CXF-6747?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Daniel Kulp resolved CXF-6747.
------------------------------
       Resolution: Workaround
         Assignee: Daniel Kulp
    Fix Version/s: Invalid


This is due to a bug in JAXB:  https://java.net/jira/browse/JAXB-986

We have a workaround via a custom JAXB plugin "cxf-xjc-bug986" which can be added to the codegen generation to strip the bad XmlSchemaType off the field.

> Starting with version 3, roundtrip wsdl -> Java -> wsdl produces output wsdl different from wsdl on input, if there are enums used. For example, I have the folowing XSD type in source wsdl:
> {code:xml}
>   <xs:simpleType name="checksumType">
>     <xs:restriction base="xs:string">
>       <xs:enumeration value="MD5"/>
>       <xs:enumeration value="SHA256"/>
>     </xs:restriction>
>   </xs:simpleType>
>   <xs:complexType name="DigestType">
>     <xs:sequence>
>       <xs:element minOccurs="0" name="digestValue" type="xs:string"/>
>       <xs:element minOccurs="0" name="digestType" type="tns:checksumType"/>
>     </xs:sequence>
>   </xs:complexType>
> {code}
> which produces (cxf-codegen-plugin:3.0.5:wsdl2java) the following Java code:
> {code:java}
> @XmlAccessorType(XmlAccessType.FIELD)
> @XmlType(name = "DigestType", propOrder = {
>     "digestValue",
>     "digestType"
> })public class DigestType {
>     protected String digestValue;
>     @XmlSchemaType(name = "string")  // WHY??
>     protected ChecksumType digestType;
> }
> {code}
> And resulting wsdl for published service looks like this:
> {code:xml}
>   <xs:simpleType name="checksumType">
>     <xs:restriction base="xs:string">
>       <xs:enumeration value="MD5"/>
>       <xs:enumeration value="SHA256"/>
>     </xs:restriction>
>   </xs:simpleType>
>   <xs:complexType name="DigestType">
>     <xs:sequence>
>       <xs:element minOccurs="0" name="digestValue" type="xs:string"/>
>       <xs:element minOccurs="0" name="digestType" type="xs:string"/>
>       <!-- xs:string instead of tns:checksumType -->
>     </xs:sequence>
>   </xs:complexType>
> {code}
> The problem is caused by @XmlSchemaType(name = "string") annotation. I think resulting wsdl should be equal to source wsdl.
