Need help with S3App.java example, from RESTful Web Services (O'Reilly)
I am trying to run the S3App.java (RESTful Web Services publisher O'Reilly) and
getting a HTTP response code of 403 Forbidden. S3App.java extends
S3Authorized.java which defines the following keys (constants),
public final static String PUBLIC_KEY = 0F9DBXKB5274JKTJ8DG2;
public final static String PRIVATE_KEY =
GuUHQ086WawbwvVl3JPl9JIk4VOtLcllkvIb0b7w;
which are not allowing me to authenticate properly. I have compiled, S3App,
S3Authorized, S3Bucket, and S3Object, successfully.
Please might someone shed some light on what I am doing wrong?
I tried the following work around. I created an account at AWS. When doing so,
I was assigned an Access Key ID and a Secret Access Key. I updated the
code's original PUBLIC_KEY value by replacing it with the value of my
AWS_Access_Key_ID and PRIVATE_KEY with my AWS_Secret_Access_Key value. The work
around failed. I figured this was a long shot and would probably fail; because
I was assuming the AWS_Secret_Access_Key is suppose to be used to create
signatures for requests made to retrieve S3 content. However, I could have
misunderstood the intent of an AWS_Secret_Access_Key and how to use it properly.
I have attached all the java code.
Cheers and thanks for reading,

Timeline for Restlet M4?
Hi Jérôme co., Do you have an idea when the remaining bugs [1] are resolved? In a project I tried to support Restlet 1.x and 2.x but recently I switched over to Restlet 2.0M3 due to API incompatibilities. Now I've got the request if it wouldn't be better to switch back to Restlet 1.x. :) I could use the 2.0 SVN snapshots, but an official release would provide a better impression. It would be great if you can provide a rough time line so I can estimate if I should switch back to 1.x or support both Restlet versions or wait for the next milestone. [1] http://restlet.tigris.org/issues/buglist.cgi?Submit+query=Submit+queryissue_status=NEWissue_status=STARTEDissue_status=REOPENEDtarget_milestone=2.0+M4 Thanks in advance, Lars -- http://www.semagia.com -- http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447dsMessageId=2367063
RE: Re: Multiple content types
Okay..
I had to add an XLS Representation for a resource and I wan to support a suffix
of .json for JSON and .XLS for Excel , but using the code below (and rest of
the code in the previous thread).
no matter what extension I use (even other than XLS OR JSON). the
Variant.Representation in my represent(Variant variant) method in the resource
class always picks up JSON as the type..
Thanks
public HelloWorldResource(Context context, Request request, Response response) {
super(context, request, response);
getVariants().add(new Variant(MediaType.APPLICATION_EXCEL));
getVariants().add(new Variant(MediaType.APPLICATION_JSON));
}
Hi Sherif,
.js is javascript
.json is json :0)
There is no need to add js or json to the MetadataService as it comes
with a bunch of common ones already.
Remove that line, and try
http://localhost:8080/firstStepsServlet/Hello.json (Notice the JSON)

Thanks Jonathan..
1. Here’s what I did to support lets say “.js” as an extension to
indicate JSON as the content type
*public* *class* FirstStepsApplication *extends* Application {
/**
* Creates a root Restlet that will receive all incoming calls.
*/
@Override
*public* Restlet createRoot() {
// Create a router Restlet that routes each call to a
// new instance of HelloWorldResource.
Router router = *new* Router(getContext());
// Defines only one route
router.attachDefault(HelloWorldResource.*class*);
*this*.getTunnelService().setExtensionsTunnel(*true*);
*this*.getTunnelService().setEncodingParameter(output);
*this*.getMetadataService().addExtension(js, *new*
Metadata(MediaType./APPLICATION_JSON/.getName(),
MediaType./APPLICATION_JSON/.getDescription()), *true* );
*return* router;
}
}
*public* *class* HelloWorldResource *extends* Resource {
*public* HelloWorldResource(Context context, Request request, Response
response) {
*super*(context, request, response);
// This representation has only one type of representation.
getVariants().add(*new* Variant(MediaType./TEXT_PLAIN/));
getVariants().add(*new* Variant(MediaType./APPLICATION_JSON/));
}
/**
* Returns a full representation for a given variant.
*/
@Override
*public* Representation represent(Variant variant) *throws*
ResourceException {
Representation representation = *null*;
*if*(variant.getMediaType() == MediaType./APPLICATION_JSON/){
representation = *new* JsonRepresentation(Hello World);
}*else* *if* ( variant.getMediaType() == MediaType./TEXT_PLAIN/){
representation = *new* StringRepresentation(
hello, world, MediaType./TEXT_PLAIN/);
}
*return* representation;
}
}
However when I call the service using the following URL
http://localhost:8080/firstStepsServlet/Hello.js the Variant type in
the HelloWorldResource is of MediaType.TEXT_PLAIN
Thanks for Your help

Have a look at
http://www.restlet.org/documentation/2.0/api/org/restlet/service/TunnelService.html
getTunnelService().setExtensionsTunnel(true);

I realize RESTLet supports multiple encodings based on the Accept
Encoding
headers. Does Restlet also have a way to allow encodings based on
URI patter
e.g. http://mystores/items/1000.json or something like that ?

Re: Premature EOF / Broken Pipe
I tried adding a second resource to my sample application. But it doesn't fail. In my actual application I have a scheduled background thread doing a POST transaction, immediately followed by a GET transaction. The Premature EOF exception has always occurred in the POST transaction. Since order does not matter between these two message exchanges, I switched them around. After doing this and trying several different scheduled time intervals for the background thread, I have yet to see it fail using the org.restlet.Client.Client using org.restlet.data.Protocol.HTTP or Protocol.HTTPS. I can't say problem solved but this is interesting and confusing at the same time. -- Timothy Aanerud On Mon, Jun 29, 2009 at 9:18 AM, Timothy Aanerud tannerudATaticonsulting.com wrote: I haven't tried switching HTTP connectors. :-( But, I did build a sanitized/stripped down example.

RangeFilter and redirects
I ran across a problem that was causing the Daemon threads in our
WadlComponent-based server to enter a busy loop. Essentially, if a Range
header was in the HTTP GET request but the server wanted to return a
redirection (e.g. via response.redirectSeeOther()), the entity would be wrapped
by a RangeRepresentation. Tunnel in to that, and RangeInputStream#read would
loop here:
// Reach the start index.
while (!(position = startIndex)) {
position += skip(startIndex - position);
}
Aside from the likelihood that there's also a bug in the handling/wrapping of a
response entity that's too small for the range, my first question here had to
do with the status code of the response itself. Should responses that are not
successful (2xx) be subject to wrapping in a RangeRepresentation?
Thanks,
David
