tli commented on CXF-29:
------------------------
With JAXB impl version 2.0.3, for schema as below:
<xs:complexType name="Base64WithDefaultValueType">
<xs:sequence>
<xs:element name="EndPart" type="xs:string" />
</xs:sequence>
<xs:attribute name="AttributeWithDefaultValue" type="xs:base64Binary"
default="1223" />
</xs:complexType>
JAXB generated code part:
public byte[] getAttributeWithDefaultValue() {
if (attributeWithDefaultValue == null) {
return DatatypeConverter.parseBase64Binary("1223");
} else {
return attributeWithDefaultValue;
}
}
Application code below will run correctly without exception.
Base64WithDefaultValueType testData = (new
ObjectFactory()).createBase64WithDefaultValueType();
byte[] checkValue = testData.getAttributeWithDefaultValue();
The JAXB impl should fixed the bug by set a concrete impl of DatatypeConverter
when create JAXB context.

> Fix For: 2.0-RC

>
> When you instantiate a class that is mapped from an element which has a
> base64Binary attribute with a default value, and subsequently call the getter
> for this attribute, the invocation will fail with a NPE unless somwhere in
> the code a DatatypeConverter was set via
> DatatypeConverter.setDatatypeConverter(javax.xml.bind.DatatypeConverterInterface
> converter):
> e.g. generated code:
> public class Foo {
> ...
> public byte[] getBase64BinaryAttr() {
> if (base64BinaryAttr == null) {
> return DatatypeConverter.parseBase64Binary("wxyz");
> } else {
> return base64BinaryAttr;
> }
> }
> }
> application code:
> Foo foo = new ObjectFactory().createFoo();
> DatatypeConverter.setDatatypeConverter(new DatatypeConverterImpl());
> byte[] value = foo.getBase64BinaryAttr()
> We should take care that somewhere in the runtime a DatatypeConverter is set,
> possibly through loading (but not necessarily registering) an extension in
> the rt-databinding-jaxb module? From the javadoc:
> " JAXB Providers are required to call this method at some point before
> allowing any of the JAXB client marshal or unmarshal operations to occur".
> We cannot take the DatatypeConverterImpl provided by sun (in the
> com.sun.xml.bind jaxb-impl.jar) as this has a protected constructor, but
> could use the one from jaxme project http://ws.apache.org/jaxme/
