I've got the initial version of xjc plugin working for supporting the
fluent api requested in RFE 115.
Any idea how I can host it at jaxb2-common ?
See below for sample usage and configuration.

build.xml
-------------
<taskdef name="xjc"
classname="com.sun.tools.xjc.XJCTask">
<classpath>
<pathelement path="/path/to/jaxb-xjc.jar"/>
<pathelement path="/path/to/jaxb-ri-fluent-api.jar" />
</classpath>
</taskdef>
<xjc ...>
<arg value="-Xfluent-api" />
...
</xjc>
Sample Usage
---------------------
Contrast the following code (which is simpler and clearer) against the
original jaxb's samples/create-marshal/src/Main.java
// Modified to use the fluent api generated by enabling the fluent-api
xjc plugin.
public class Main {
// This sample application demonstrates how to construct value classes
// and create a java content tree from scratch and marshal it
// to XML data
public static void main( String[] args ) {
try {
// create a JAXBContext
JAXBContext jc = JAXBContext.newInstance( "primer.po" );
// create an empty PurchaseOrder
PurchaseOrderType po = new PurchaseOrderType()
// set the required orderDate attribute
.withOrderDate( getDate() )
// set the required shipTo address
.withShipTo( new USAddress()
.withName("Alice Smith")
.withStreet("123 Maple Street")
.withCity("Cambridge")
.withState("MA")
.withZip( new BigDecimal("12345")) )
// set the requred billTo address
.withBillTo( new USAddress()
.withName("Robert Smith")
.withStreet("8 Oak Avenue")
.withCity("Cambridge")
.withState("MA")
.withZip( new BigDecimal("12345" )) )
;
// create an empty Items object
Items items = new Items();
// get a reference to the ItemType list
List<Items.Item> itemList = items.getItem();
// start adding ItemType objects into it
itemList.add( new Items.Item()
.withProductName("Nosferatu - Special Edition (1929)")
.withQuantity(5)
.withUSPrice(new BigDecimal( "19.99" ))
.withComment(null)
.withShipDate(null)
.withPartNum("242-NO"))
;
itemList.add( new Items.Item()
.withProductName("The Mummy (1959)")
.withQuantity(3)
.withUSPrice(new BigDecimal( "19.98" ))
.withComment(null)
.withShipDate(null)
.withPartNum("242-MU"))
;
itemList.add( new Items.Item()
.withProductName("Godzilla and Mothra: Battle for
Earth/Godzilla vs. King Ghidora")
.withQuantity(3)
.withUSPrice(new BigDecimal( "27.95" ))
.withComment(null)
.withShipDate(null)
.withPartNum("242-GZ"))
;
// set the required Items list
po.setItems( items );
// create an element for marshalling
JAXBElement<PurchaseOrderType> poElement = (new
ObjectFactory()).createPurchaseOrder(po);
// create a Marshaller and marshal to System.out
Marshaller m = jc.createMarshaller();
m.setProperty( Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE );
m.marshal( poElement, System.out );
} catch( JAXBException je ) {
je.printStackTrace();
}
}
private static XMLGregorianCalendar getDate() {
try {
return DatatypeFactory.newInstance().newXMLGregorianCalendar(new
GregorianCalendar());
} catch (DatatypeConfigurationException e) {
throw new Error(e);
}
}
}

However, although JMods has an internal "mods" int field, there seems no API to gain access to it. (I don't want to resort to reflection to break the API.) Meanwhile, the required "mods" parameter of JDefinedClass.method is an int.
