RE: How to implement an AMQP client+server connector?

Jerome Louvel — 2013-05-14T20:24:37

Hi Paul,

The class to extend should be org.restlet.engine.ClientHelper, it will be much easier.

You can have a look at                           org.restlet.engine.local.FileClientHelper for an exmaple of binding of a pseudo-protocol to the Restlet API.

Best regards,
Jerome

How to implement an AMQP client+server connector?

Paul Sprague — 2013-05-07T14:51:25

Hello!

Can anyone on this list make some recommendations as to how a connector could be implemented that isn't based on HTTP? I was initially think that I needed to implement a connector, connection, controller, in/outbound ways, etc. But after looking at the code I'm not so sure this is the correct approach.

My thought was to leverage Apache Qpid as the underlying implementation. I just need some idea as to how I can integrate it into restlet.

Thanks,
Paul

Hi Juan,

Are you using virtual hosts with a Restlet component? What is your runtime
environment?

Thanks,
Jerome

access webservice with hostname versus localhost

Juan — 2013-01-07T20:11:59

I have been playing with the Restlet examples, seems that the URI defined in the router.attach call (http://localhost:8111/hello) needs to called exactly like it from the clients, including the host name. If my local machine is named galaxy18 and i run the webservice and local client, I can only access it via localhost:8111/hello. If I change the router.attach to http://galaxy18:8111/hello then the client can access it with galaxy18 but not with localhost.

I don't like hardcording, especially machine names, if you can imagine this will be a pain if my webservice is running on different machines.

Is this an instance where I need to use read the hostname into a variable then use that in the router.attach or am i missing something basic here?

Restlet 2.1-RC5 and GWT 2.4 POST entity issue

Cyril Lakech — 2012-07-23T17:19:20

Hi,

We use Restlet 2.1-RC5 and GWT 2.4 with restlet gwt extension and we
face a 415 error on posting content from the GWT app to the restlet
API: "Too few tokens in RPC request" (see errors below [1])

We can't find any solution to this exception. Debugging restlet/gwt
doesn't help...

Here is a sample of an entity sent to the server :

7|0|3|/wikeo-core/business/v2/families/|null|com.adeo.wikeo.business.family.domain.Family/881681172|1|2|3|

GET works perfectly, but when we try to POST/PUT content to the server
we get a 415 error

Any idea ?

RE: Restlet Framework 2.2 - Build issues and Eclipse/OSGi development

Andy Dennie — 2012-05-19T20:56:09

Thanks, Shaun.  I actually started down the road of writing a script to install all the artifacts using the maven-install-plugin, but then after rummaging around in the ant build scripts a bit (I don't really know ant) and a certain amount of trial and error, I discovered that the pom files can still be generated in a repository-style directory structure with the following custom.properties file (e.g. for building 2.1-RC4):

major-number: 2
minor-number: 1
release-number:4
version-minor: ${major-number}.${minor-number}
release-type: RC
version-full: ${version-minor} Release Candididate
version-maven: ${version-minor}-${release-type}${release-number}
version-manifest-prefix: ${version-minor}.0.0.rc4-
verify: false
maven: true


... and then I could just write a small batch file to copy/paste the generated directory structure into my maven repo.  Hopefully this capability will be retained in the ant build (presumably it would be needed to support installation into the repo at maven.restlet.org).

A request -- if you remove all of the pom.xml files, would it be possible to provide an alternate way to install the artifacts from my Restlet build into my local maven repo, after building with ant?

Re: Re: Filter/FilterChain

Sean Landis — 2012-05-15T15:08:34

The approach taken by Restlet is a well-known pipes and filters
architecture. That would resonate with people accustomed to that
common style. Have you considered coding to the JSR-311 API? I'm not
sure how well Restlet supports that, or whether it addresses your
stylistic concerns, but its worth checking out.

RE: Re: Filter/FilterChain

Dencel — 2012-05-15T14:52:48

I am using Restlet to serve my requests, no servlet container available/no need for it. 

I understand Restlets filtering mechanism, but I think it's not as clean as the Filter/FilterChain mechanism of Servlet. Imo restlets filtering mechanism requires unnecessary code and unnecessary objects. 

Check this trivial example: 
Router router = new Router();
router.attachDefault(new Directory(new File("www"));
Authorizer userAuthorizer = new Auth...;
userAuthorizer.setNext(new Directory(new File("www/secure")));
router.attach("/secure",userAuthorizer);
Authorizer adminAuthorizer = new Auth...;
adminAuthorizer.setNext(new Directory(new File("www/secure/admin")));
router.attach("/secure/admin",adminAuthorizer);
orAuthorizer = new Auth...;
orAuthorizer.setNext(new Directory(new File("www/resources")));
router.attach("/resources",orAuthorizer);


I think something like below would be more meaningful/readable: 
Authorizer userAuthorizer = new Auth...; /* Transparent filtering not support in codebase */
Authorizer admi

Re: Filter/FilterChain

Sean Landis — 2012-05-15T14:20:22

You can insert filters anywhere in the routing structure as you did.
In addition, you can deploy your Restlet WS in a servlet container if
you like, and take full advantage of that style of filtering. What
else do you need?

Filter/FilterChain

Dencel — 2012-05-15T14:01:35

I can't get my head around, why there is no filtering capability like servlet's Filter/FilterChain available in Restlet.Is there a specific design decision at the basis for this? 

Something like: 
Authenticator authenticator = new MyAuthenticator();
Router router = new Router()
router.attach("/secure",MyResource.class);
router.attachFilter("/secure",authenticator);
router.attach("/secure2",MyResource2.class);
router.attachFilter("/secure2",authenticator);
router.attachDefault(PublicResource.class);

Looks more meaningful to me then: 
Authenticator authenticator = new MyAuthenticator();
authenticator.setNext(MyResource.class);
router.attach("/secure",authenticator);
authenticator = new MyAuthenticator();
authenticator.setNext(MyResource2.class);
router.attach("/secure2",authenticator);

In the first method there is only one filter entity created vs the two entities on the 2nd example. I've implemented this already in my own project, but I like to know what the downside is of this approach. Imo the only downs

setting up git repos and branches

Andy Dennie — 2012-05-14T18:49:55

Hi everyone,

I want to be able to occasionally submit fixes to Restlet, while maintaining local branches on my dev machine that (a) keep up-to-date with Restlet's branches, and (b) contain my fixes, including those that I have not yet submitted back to Restlet, and those I have submitted but which have not yet been accepted and merged (and maybe never will be, but nevertheless I need those changes for my own use).

I'm pretty new to git, and I'd like to get off on the right foot here.

Here's what I'm thinking, please advise on whether this makes sense or if there are preferable alternatives.

As an initial setup:

- clone "https://github.com/restlet/restlet-framework-java" to my local dev environment
- in my local repo, create branches off each of the Restlet-defined branches, e.g. branch "my-master" from "master", "my-2.2" from "2.2", etc.
- on github, fork restlet/restlet-framework-java to adennie/restlet-framework-java so that I have a place to push fixes, and from which I can send pull requests to rest

Hi Tal and all,

 

I've been able to complete the first tasks in Git master branch:

·         The Eclipse projects dont rely on PDE/OSGi anymore but on regular
Eclipse projects dependencies

·         Manifest and pom.xml files have been removed

·         Only Java nature has been kept on the Eclipse project files

·         The code now uses Java 1.6 and compiles fine in Eclipse

·         Retrotranslator support (for Java 1.4) has been removed altogether


·         All unit tests pass fine in Eclipse (tested on Win 7)

 

We still need to fix some issues with the Ant build script that prevent the
whole thing to run through properly. Also, documentation needs to be updated
and completed. I have started this task in GitHub wiki, migrating/adapting
existing content from the Daisy wiki:

I had a little research in the web and a lot of developer recommend your project "restlet" that he so lite simple and give a very good performance.

but when I try to learn about it, it's very hard to learn.
you say a very little instruction and a small part of the code.

is there any where a full code sample and a guide  of restlet especially whit android an xstream?

How to use restlet with proxy and how to use extensions in general

Michael Stein — 2012-05-12T10:08:27

Hi all, 
unfortunately I am not very familiar with restlet to be able to set up a
working project where to send a getRequest over a company proxy which needs
authentication. Without a proxy  this simple snippet works perfect:

ChallengeResponse authentication  = new
ChallengeResponse(ChallengeScheme.HTTP_BASIC, user, password);
ClientResource resource = new ClientResource(this.resourceUri);
resource.setChallengeResponse(authentication);
resource.get().write(byteArrayOS);


But although I googled since some days I cannnot find a clear example on how
to use proxAuthentication. What I found is that I could use the
hhtpClient-Extension from apache for example But then the question is on who
to use this extension?? Is it necesary to use the standard methods and
classe from the httpClient lib directly? Or am I able to call everything by
the use of restlet-Api. The examples of who to use HttpClient with proxy
seems clear to me, but who does this work as part of restlet?

Thanks in advance for all replies on who to
