XJC javaType adapter in complexType

问题

I want to get XJC to use the javaType tag in a complexType when generation beans. Is this not allowed? I'm really missing good documentation and some understandable error message.

Here is what I am trying which fails with the errors:

• compiler was unable to honor this conversion customization. It is attached to a wrong place, or its inconsistent with other bindings.
• (the above customization is attached to the following location in the schema)

Here is the XSD:

<xs:complexType name="MyMap">
  <xs:annotation>
    <xs:appinfo>
      <xjc:javaType name="my.company.HashMapHidingGenerics" adapter="my.company.adapter.MyMapAdapter" />
    </xs:appinfo>
  </xs:annotation>
  <xs:sequence>
    <xs:element minOccurs="0" maxOccurs="unbounded" name="entry" type="MyEntry"/>
  </xs:sequence>
</xs:complexType>
<xs:complexType name="MyEntry">
  <xs:attribute name="someAttribute" use="optional"/>
</xs:complexType>

Bad news: <javaType> only supports simple types (see Binding Declarations and Is it possible to use JAXB to map from schema to a java.util.Map?).

However you can achieve what you need by using @XmlAdapter.
