JAXB setting javaType for xs: integer creates @XmlElement with "type = String.class"

When creating Java beans from XSD with XJC, I need to map xs:integer to Integer , not BigInteger . I added the javaType tag to my JAXB configuration file (as said in many answers from this site), and it worked fine.

But in the generated code, I noticed that the @XmlElement tag now has a type=String.class .

So now I wonder why String ?
Is it because parsing and printing methods are being converted from / to string objects?

I tried using xjc:javaType instead of jaxb:javaType , which allowed jaxb:javaType to replace the generated Adapter1<String, Integer> with the custom MyAdapter<BigInteger, Integer> , but it happened the same way.

If this is normal XJC behavior, is it possible to configure it to generate code without this parameter or with a value other than String ?

Please note that everything is working fine, but I would like to understand.
I also use Enunciate to document my API and it seems to confuse this type thing (but this is probably an error in Enunciate).

I am using JAXB RI 2.2.6, and here are some code snippets to illustrate my question:

bindings.xjb

 <jaxb:bindings version="2.0" ...> <jaxb:globalBindings> <jaxb:javaType name="java.lang.Integer" xmlType="xs:integer" parseMethod="..." printMethod="..." /> </jaxb:globalBindings> </jaxb:bindings>

Field Definition in XSD

 <xs:complexType name="MyType"> <xs:sequence> <xs:element name="myField" type="xs:integer" /> </xs:sequence> </xs:complexType>

Java generated field

 @XmlElement(namespace = "...", required = true, type = String.class) @XmlJavaTypeAdapter(Adapter1.class) @XmlSchemaType(name = "integer") protected Integer myField;

I know this is an old question, but for people who are still looking for an answer: using type xs:int instead of xs:integer will create a normal java int instead of Biginteger .
