RE: Trouble Getting Query Parameters
Hi Andrew, Thanks for reporting this issue. I've just updated our FormReader logic to be more flexible. I've also added a regression test case. Checked in SVN trunk.

Re: Trouble Getting Query Parameters
Your URL has an immediate ampersand after the question mark: ?&_dc=1244741620627&callback=stcCallback1001 Maybe try removing the first ampersand: ?_dc=1244741620627&callback=stcCallback1001 I kind of hope that it doesn't care about it, but you never know.

Re: Trouble Getting Query Parameters
I'm starting to understand what may be going on... when EXT.js makes the request for my URI, the query string looks like this: ?&_dc=1244741620627&callback=stcCallback1001 And the org.restlet.engine.util.FormReader is not able to parse the parameters. Here's the error: 06/11/2009 11:33:40.640 [http-0.0.0.0-8080-1] [STDERR] [ERROR] Jun 11, 2009 11:33:40 AM org.restlet.engine.util.FormReader addParameters WARNING: Unable to parse a form parameter.

Maybe my best option is to try and modify what EXT.js is appending on my URI when it makes the request? Any thoughts?

Trouble Getting Query Parameters
I'm new to Restlet and I'm having trouble accessing the query parameters in
my ServerResource.
I'm using a URI comparable to:
http://localhost:8080/myapp/zipcodes/{zip}/locations/{location}/users/{user}?&callback=someCallbackFunction
The client is written in EXT.js and is expecting me to wrap the json object
in a function with a name the 'callback' query parameter specifies.
I can't for the life of me understand what I'm doing wrong in trying to
access this query parameter.
My application class is similar to this:
package com.myapp.applications;
import org.restlet.Application;
import org.restlet.Context;
import org.restlet.Restlet;
import org.restlet.routing.Router;
import com.myapp.resources.ZipsLocsUsersResource;
public class MyApplication extends Application {
public MyApplication() {
}
public MyApplication(Context context) {
super(context);
}
@Override
public Restlet createRoot() {
// Create a router Restlet that routes each call to a
Router router = new Router(getContext());
router.attach("/myapp/zipcodes/{zip}/locations/{location}/users/{user}",
ZipsLocsUsersResource.class);
return router;
}
}
And my ServerResource class is similar to this:
package com.myapp.resources;
import org.restlet.data.Form;
import org.restlet.data.Parameter;
import org.restlet.data.Reference;
import org.restlet.data.Request;
import org.restlet.representation.Representation;
import org.restlet.representation.StringRepresentation;
import org.restlet.resource.Get;
import org.restlet.resource.ServerResource;
import com.myapp.representation.JsonRepresentation;
public class ZipsLocsUsersResource extends ServerResource {
private String zip;
private String location;
private String user;
private String callback;
@Get
public Representation represent() {
this.zip = (String) getRequest().getAttributes().get("zip");
this.location = (String) getRequest().getAttributes().get("location");
this.user = (String) getRequest().getAttributes().get("user");
Form form = getRequest().getResourceRef().getQueryAsForm();
this.callback = form.getFirstValue("callback");
String jsonString = "{user:\"" + this.user + "\", loc: \"" +
this.location + "\", zip:\"" + this.zip + "\"}";
if (this.callback != null) {
jsonString = this.callback + "(" + jsonString + ")";
}
Representation result = new JsonRepresentation(jsonString);
return result;
}
}
When I run with a debugger, my form always ends up being empty... and when I
dig through the request I can't find the parameters anywhere. I am wanting
this parameter to be optional. I'm not sure if I'm setting my application up
wrong, or if I'm trying to get the parameters the wrong way? This is on a
GET request, and everywhere I look, folks seem to not be able to access the
query parameters until they try the
getRequest().getResourceRef().getQueryAsForm() way of doing it.
Thanks in advance for your help!
Regards,
Andrew
