Thanks for the info, still trying to get my head around this.
The actual example I am working with is the "invoice.xsd" that is included
in the source. < found here:
http://www.castor.org/srcgen-example.html#Running-the-XML-code-generator>
It was analogous to what I am trying to achieve. So I took the invoice.xsd
and simply ran source generator command like so:
<
java -cp %CP% org.exolab.castor.builder.SourceGeneratorMain -i invoice.xsd
-package test
That command created java files for each of the complex types and a
directory named "descriptors" which also have java files in there.
Could someone explain the difference between the src and the descriptors?
What is each of their jobs? This is my first run with XML to java binding.
Secondly, I decided to try and marshall this, so I created a Invoice item,
and added ShipTo, Customer, Item, ItemAttributes, etc. objects to the
invoice in an attempt to marshall the data like so: (see test class), but
I am unable to get the "duration" to work. I get errors like so:
see (error below).
// test class
public static void main(String[] args) {
Item item = new Item();
item.setQuantity(100000);
item.setId("1");
item.setInStock(false);
item.setCategory("my_category");
item.setPrice(new BigDecimal("100.00"));
Address address = new Address();
address.setCity("my_city");
address.setState("MO");
address.setStreet1("76777777 mockingbird");
address.setStreet2("other street");
address.setZipCode("77779");
Customer customer = new Customer();
customer.setName("Scott");
customer.setPhone("300-300-3333");
customer.setAddress(address);
ShipTo shipto = new ShipTo();
shipto.setCustomer(customer);
ShippingMethod shipmethod = new ShippingMethod();
shipmethod.setCarrier("carrier");
shipmethod.setOption("UPS");
Invoice inv = new Invoice();
inv.setShippingMethod(shipmethod);
inv.setShipTo(shipto);
inv.addItem(item);
try {
FileWriter writer = new FileWriter("invoice.xml");
Marshaller.marshal(inv, writer);
} catch (Exception e) {
System.err.println(e.getMessage());
e.printStackTrace(System.err);
}
}

Hmm ... let me try to understand one thing here. When you have used the
XML code generator, you have turned off creastion of descriptor classes
and turned on creation of a mapping file, correct ? If that's the case,
why ? It should be the other way around. See below .....
Please note, that a binding file is something completely different.
The term 'binding file' is used in the context of code generation to
overcome naming collisions.

Assuming that you have generated source code (including descriptor
classes, that is) from your XML schema, here's what you have to do to
marshal an object instance to XML.
<code>
XMLContext context = new XMLContext();
Marsdaller marshaller = context.createMarshaller();
YourObject yourObject = .... ;
marshaller.marshal(yourObject);
</code>
If (and only if) you have the descriptor classes on your classpath,
Castor will just marshal XML according to your definitions in your XMl
schema.
Does this make sense ?
