POST with accept variants
I want to be able to return an XML or JSON response from a POST request depending on the HTTP accept header and was wondering if its possible to leverage the existing variant stuff from the represent(variant) method from within the POST handler? or do I just need to check the header manually? thanks in advance -- http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=2784424

Multiple applications with serverservlet and < v2.0
Quick question is it possible to have multiple restlet applications with restlet < 2.0 (e.g.1.1.9) when using the servlet extension and config in a web.xml file? -- http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=2719537
RE: Re: Reading/setting date header fields is extreme slow on android
I have also come across this problem, the restlet client chooses between using
simpledateformat and internetdateformat depending on the format of the date
header passed to it. simpledateformat is slow because it loads all the timezone
names for each instance.
It is possible that if your server uses internetdateformat for its date headers
then the client will too but I have not been able to actually confirm this yet
The decision code is in DateUtils.parse
if (FORMAT_RFC_3339.get(0).equals(format)) {
parser = new InternetDateFormat(TIMEZONE_GMT);
} else {
parser = new java.text.SimpleDateFormat(format,
java.util.Locale.US);
parser.setTimeZone(TIMEZONE_GMT);

RE: Re: ClientResource without error? (Restlet 2.0.5)
Oh I thought he only wanted the status. but could you not just call res.getResponse().getEntity()? -- http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=2705025
RE: ClientResource without error? (Restlet 2.0.5)
Surround the get() with a try catch, catch the resource exception and check the
status there as well as after the get(), something like
ClientResource res = new ClientResource();
Status stat;
try{
res.get();
stat = res.getStatus();
} catch (ResourceException e){
stat = res.getStatus();
}

RE: Problem using android 2.0.4 and apache http client with HTTPS
I extended the HttpClientHelper and overrode configure to register the https
scheme
schemeRegistry.register(new Scheme("https",
SSLSocketFactory.getSocketFactory(), 443));
and now have https working
So now just the other problem where the client seems to stop in the middle of
making multiple requests, see original post

RE: Problem using android 2.0.4 and apache http client with HTTPS
Ignore that last problem I mentioned it was my fault. I had a static Client object but was also using a Decoder that had a shorter lifecycle. So when the Decoder was finalized it was of course calling stop() on the Client -- http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=2702694
RE: Problem using android 2.0.4 and apache http client with HTTPS
OK I can see in the HttpClientHelper that it only registers the http scheme and
not the https as its own javadoc says
/**
* Configures the scheme registry. By default, it registers the HTTP and the
* HTTPS schemes.
*
* @param schemeRegistry
*The scheme registry to configure.
*/
protected void configure(SchemeRegistry schemeRegistry) {
schemeRegistry.register(new Scheme("http", PlainSocketFactory
.getSocketFactory(), 80));
}
Is that a bug then or am I just missing something?

Problem using android 2.0.4 and apache http client with HTTPS
Hi, I've been having trouble to getting the apache http client working on android. I have the restlet.jar and ext.httpclient.jar on my class path and I am adding the HttpClientHelper as per the instructions, Engine.getInstance().getRegisteredClients().add(new HttpClientHelper(null )); I am creating my Client as a static so I can reuse it with clientresource.setNext(client); OK first thing learnt, dont initialise your client in the member declaration because it will be created before the Engine has the client helper registered with it. doh. Second, you need to name the Apache client helper class when you create your Client otherwise the engine just uses the first helper in its list that matches the protocol which is the default http client. That is not mentioned anywhere in the docs (that I can find) So finally I got it using the apache http client but when I call get on a uri with https I get the following error: java.lang.IllegalStateException: Scheme 'https' not registered. at org.apache.http.conn.scheme.SchemeRegistry.getScheme(SchemeRegistry.java:80) at org.apache.http.impl.conn.DefaultHttpRoutePlanner.determineRoute(DefaultHttpRoutePlanner.java:107) at org.apache.http.impl.client.DefaultRequestDirector.determineRoute(DefaultRequestDirector.java:565) at org.apache.http.impl.client.DefaultRequestDirector.execute(DefaultRequestDirector.java:292) at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:555) at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:487) at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:465) at org.restlet.ext.httpclient.internal.HttpMethodCall.sendRequest(HttpMethodCall.java:331) at org.restlet.engine.http.adapter.ClientAdapter.commit(ClientAdapter.java:112) at org.restlet.engine.http.HttpClientHelper.handle(HttpClientHelper.java:110) at org.restlet.Client.handle(Client.java:177) at org.restlet.routing.Filter.doHandle(Filter.java:156) at org.restlet.routing.Filter.handle(Filter.java:203) at org.restlet.resource.ClientResource.handle(ClientResource.java:928) at org.restlet.resource.ClientResource.handle(ClientResource.java:999) at org.restlet.resource.ClientResource.handle(ClientResource.java:896) at org.restlet.resource.ClientResource.handle(ClientResource.java:851) at org.restlet.resource.ClientResource.handle(ClientResource.java:759) at org.restlet.resource.ClientResource.get(ClientResource.java:492) at com.hullomail.android.messaging.webapi.HmBaseResource.get(HmBaseResource.java:148) Any ideas how to fix that? On top of that I am finding with both clients (I tried the apache one with just http) that when I make multiple requests at the same time I see from the logs that sometimes the client stops before one the request completes and an exception is thrown.

RE: Correct way to use android ClientResource
I've traced further into the code and it seems to be the BaseHelper class that is creating a controller service and worker service. This happens for each new clientresource object.

Correct way to use android ClientResource
Just a quick one, (i hope) I am using the android ClientResource in my android app and I am wondering what is the correct way to use that object when it is necessary to make multiple requests on it. Should I be creating one resource object and holding a reference to that or is it preferable to create a new object for each call? I have tried the latter way and it seems OK except each call seems to create a new Executor service and 2 threads that are never cleared up even though I am not using the asynchronous functionality. Perhaps I am simply missing a method call or something? kind regards Chris -- http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=2641904

Considering Restlet for my web service
Hello, I am currently trying to implement web service that will run on our existing servlet based system. Restlet looks almost perfect for what I need but there are two things that I need to be sure I can do before I can proceed with it. 1) Authentication - I need to allow a user to authenticate themselves before accepting any other requests from that user 2) Server side caching - I need to keep data retrieved from a 3rd party system temporarily cached in memory for each user, to open new a connection and retrieve this data is too expensive an operation to do on every request. Of course you know I am going to say I need some sort of session :) but I also agree that to do without the session is a good way to go. So do you have any suggestions as to what to do? I am sure others must have come up against this scenario. Or perhaps restlet is not the correct solution in this case? Any advice is much appreciated, this is my first stab at a web service and I have looked at most of the other possible java web service solutions but they all seem so overweight and disparate (which I guess is why restlet was created in the first place) thanks in advance Chris D -- http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=2376280
