Hello,
I am trying to find some documentation on how to programatically handle
errors. I am using the SourceGeneratorMain for now, which creates the java
files and the descriptors (for validation?).
Anyway, I am intentially trying to break some of the "validation" rules,
ie. setting incorrect data and of course getting errors. Problem is, right
now, due to my lack of understanding, I am just throwing exceptions in my
main application.
Now I would like to be able to understand how I can control what errors
are occuring, and how I can show the errors as opposed to throwing them.
Is there some documents on this? or a link somewhere?
I was thinking you would call Marshall on the object, then ask for
something back like a errors object?. Not sure how this works.
Thanks
Scott
// here is what I am doing now. How can I interrogate the errors this
produced. In this example, I set an invalid phone. It should be
\d{3}-\d{3}-\d{4}, but I left one off. This is my test. I would like to
pull back an object that would encapsulate the error as opposed to
throwing it.
public static void main(String[] args) throws Exception {
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("300-300-333");
customer.setAddress(address);
ShipTo shipto = new ShipTo();
shipto.setCustomer(customer);
ShippingMethod shipmethod = new ShippingMethod();
shipmethod.setCarrier("carrier");
shipmethod.setOption("UPS");
shipmethod.setEstimatedDelivery(new Duration("PT130S"));
ShippingDate shipDate = new ShippingDate();
shipDate.setDate(new Date());
shipDate.setTime(new Time());
Invoice inv = new Invoice();
inv.setShippingMethod(shipmethod);
inv.setShipTo(shipto);
inv.setShippingDate(shipDate);
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);
}
}
