    JWT example for Picketlink 2.6.0

    Esteve Aviles Newbie



      We  are interested in using picketlink-json package to implenent JWT. We have seen that the documentation is not ready. Is there any example out there showing how to use this package?


      Does this package implements the filter to allow Stateless Rest Web services?


      Thanks in advance,

          Please check AngularJS quick start under https://github.com/jboss-developer/jboss-picketlink-quickstarts/tree/master/picketlink-angularjs-rest

          After I digged into details I understand that initial authentication request is performed with BASIC authentication (check servlet filter class defined in web.xml) and then token is generated. That token is exchanged between client and servier in HTTP header. For your use case it would be good to use stateless Identity which also is available in Picketlink 2.6.0.Final.


          I have spent some time recently to find out how JWT is implemented in Picketlink and realized that JWT and JWS (signed token) is implemented but there are still some things to implement for example JWE (check class JsonWebEncryption).


          I'm currently working on stateless token-based authentication for REST services too. Will put some code later.


          I encourage you to check Picketlink source code. It's well written and easy to understand.

            Hi Esteve,


                There is not docs for PicketLink JSON, yet. We're working to support JWE and JWK. Once we finish that we're going to provide more docs.


                For now, I would suggest you to take a look at the test cases provided by this module. I think they are a useful source to understand and see how to use it.

              Hey Esteve,


                  You can check an initial documentation for the PicketLink JSON API here.


                  It still need a review before push that to our official documentation. But it can help you meanwhile.

                The picketlink-angularjs-rest quickstart has provided good insights to the JSON implementation and usage. During signin, a POST to <contextRoot>/authc is sent from the angular app using the LoginResource


                I have been selectively adding components from the quickstart to ensure understanding of implementation in the quickstart and where likely to enhance, etc within my add. Registration and activation services are working as expected. /authc returns a 404 in my app

                No such endpoint in the quickstart, so can only assume it is being contributed by picketlink-json. Initial investigation of source has not made me any the wiser.


                My question is what is contributing this REST endpoint.

                  Hey Mike,


                      The "/authc/" does not exists. You may notice that the security filter is intercepting every single URL from "/rest/private/*.


                      What the filter does is check if the request is authenticated, if not try to extract credentials from it. In this case, BASIC credentials. Once the user provides valid credentials, the filter will validate them and issue a token accordingly. The token is written to the response. All that is done by a specific authentication scheme, the TokenAuthenticationScheme.

                    Dear Pedro,


                    I have a problem that i don't understand... when i try to use your code for picketlink-angularjs app i'm aple to register and autentichate the token..

                    but if i try to log in.. i have this error :

                    i tryed to debug all the steps and i noticed that the security listners seem not be called !

                        Hi Pedro,


                        I found the problem, i'm using an  EAR application  derived from your example picketlink-angularjs-rest 2.7.0 CR1.

                        i have the ejb part with the logic into the jar and all the web in war.

                        i'm using wildfly 8.1 final.


                        I think there are some problems in the listener, so if i put all the jars into the war, everything is correctly running, if i move the picketlink jars

                        and the code from web to ejb jar, i have that problem...


                        any ideas?

                          I know Resteasy provides some default provider implementation to transform basic types such as Map and List. Maybe you are missing some resteasy dependency in your EAR's jboss-deployment-structure.xml.

                              Dear Pedro

                              Unfortunally, this kind of application ONLY works if you put all the requestet jars into WEB-INF/lib folder... if you try to migrate from Uber picketlink jar to Wildfly/picketlink/module and import it with jboss-deployment-structure.xml or maven manifest import, simply you receive back the problem that i have...


                              I tryed to debug a lot wildfly and picketlink to find the problem but is too deep ..


                              did you never try to migrate Rest Picketlink security into and EAR project with module dependencies?

                                Hey Andrea,


                                   I have reproduced your issue. You are not alone


                                   However, I don't have a solution for that yet. I'm trying to get some feedback from Resteasy team and check if we're missing something when using dependencies from modules.


                                   This is probably a classloader issue when using modules, not sure if it is related with PL.

                                  I'm facing the same problem on JBoss EAP 6.3.


                                  Caused by: org.jboss.resteasy.core.NoMessageBodyWriterFoundFailure: Could not find MessageBodyWriter for response object of type: java.util.HashMap of media type: application/octet-stream


                                  In my case it occurs when a REST method that return a List is accessed .


                                  pcraveiro I think is related to picketlink because before setup Picketlink token authentication on my project all rest resources are ok.
