JAXB Unmarshalling
I am going on playing with the restful_jaxrs sample demo
In the Client.java there are these lines
...
URL url = new URL("http://localhost:9000/customerservice/customers/123");
InputStream in = url.openStream();
System.out.println(getStringFromInputStream(in));
....
What if I did not want to display the XML content (ie the XML
representation of customer whose Id is 123)
But rather I would like to get the actual instance of Customer with id is 123
Is there some Unmarshalling method to do that , something like
...
URL url = new URL("http://localhost:9000/customerservice/customers/123");
InputStream in = url.openStream();
// Hypothetic code
Customer customer = (Customer) getObjectFromInputStream(in);
...
How would I implement this
Object getObjectFromInputStream(InputStream in)
method ?
I guess I would have to get a JaxbContext before I can get an Unmarshaller ?
Thanks for your help
Eric

Hi
I'm wondering, are you actually asking for a code generation be done on a client side with the help of a description language like WSDL 2.0 or WADL ?

This is a nice refactoring effort and indeed the code looks simplier.
My point was not really to do with the fact that the code in your original proposal was a bit verbose.
IMHO it's kind of trying to catch 2 rabbits at the same time : attempt to write just a simple HTTP code and still expect the
runtime to nicely map the incoming data into classes like Customer.
In the end one does not get the flexibilty the client code can get from technologies like XPath (as far as writing a robust cliend code is concerned). And one needs to write manually some utility code which will map the in XMl to *generated* types like Customer. What's the point ?
I'd either go for a pure XML approach or would use a description language to do all the client bootsrapping stuff for me.

RE: JAXB Unmarshalling
Posted by "Liu, Jervis" <jl...@iona.com>.
Well, if you REALLY want, you can hide the calling of JAXB in an util, for example you can extend HTTP Client to make it aware of a JAXBContext and be able to accept and return a JAXB object, for example following code:
String inputFile = client.getClass().getResource("update_customer.txt").getFile();
File input = new File(inputFile);
PutMethod put = new PutMethod("http://localhost:9000/customerservice/customers");
RequestEntity entity = new FileRequestEntity(input, "text/xml; charset=ISO-8859-1");
put.setRequestEntity(entity);
HttpClient httpclient = new HttpClient();
int result = httpclient.executeMethod(put);
String response = put.getResponseBodyAsString()
Will become:
PutMethod put = new PutMethod("http://localhost:9000/customerservice/customers");
Customer customer = new Customer();
RequestEntity entity = new JAXBRequestEntity(customer);
put.setRequestEntity(entity);
HttpClient httpclient = new JAXBHttpClient(jaxbcontext);
int result = httpclient.executeMethod(put);
Customer updatedCustomer = put.getResponseBodyAsJAXB()
Of course, you can also add some nice things such as handle checked exception in this HTTP Client extension, so that it becomes:
try {
int result = httpclient.executeMethod(put);
Customer updatedCustomer = put.getResponseBodyAsJAXB()
} catch (CustomerNotFoundException e) {
} catch (WebServiceException e) {
}
Does this make sense?

That's pretty interesting all right.

that your code is so light and free :-)

Jervis,

BTW I had to replace with
public Object getObjectFromInputStream (Class<?> type, InputStream is) {
so that I could call a getObjectFromInputStream(Customer.class, is)
Would not it be nice if this piece of code was part of CXF , because I
guess I am not the only one who needs this

By the way, can this approach (which uses JAXBContexts) work for you in CXF? :
http://weblogs.java.net/blog/mhadley/archive/2006/03/restful_web_ser_1.html
You'd still need a schema describing the data like Customer, etc...
