    Problem with Resteasy: NoMessageBodyWriterFoundFailure

    Johannes Hollerer Newbie

      I tried the RESTEasy configuration (for interconnection with GWT) by modifying the components.xml file but when calling the method i get the failure:



      02:40:18,452 ERROR [SynchronousDispatcher] Failed executing GET /customer
      org.jboss.resteasy.core.NoMessageBodyWriterFoundFailure: Could not find MessageBodyWriter for response object of type: java.util.ArrayList of media type: application/xml

           at javax.servlet.http.HttpServlet.service(HttpServlet.java:717)



      The configuration is like that:




      <framework:entity-home name="customerHome"
                             entity-class="com.amergy.restfultestapp.entity.Customer"
                             auto-create="true"/>
      
      <framework:entity-query name="customerQuery"
                        ejbql="select c from Customer c" order="lastname"/>
      
      <resteasy:resource-home path="/customer" name="resourceCustomerHome"
                              entity-home="#{customerHome}" entity-id-class="java.lang.Long"
                              media-types="application/xml application/json"/>
      
      <resteasy:resource-query path="/customer" name="resourceCustomerQuery"
                               entity-query="#{customerQuery}" entity-class="com.amergy.restfultestapp.entity.Customer"
                               media-types="application/xml application/json"/>




      Can someone point me a hint - what the problem is - as i cannot define any Writer within the Components.xml file ??
      Is there some docu regarding that configuration within the components.xml file ?

          Solved it - the problem where some missing jars !


          thanks

            It still does not work !!


            When i make the whole function manually with functions (and specify as return type application/xml - it works!
            But when i try to use the build in function out of the components.xml it still shows the error !

              Is the exception still the same? If yes you are probably missing the resteasy-jaxb-provider.jar in your classpath. This library contains ready-made reader and writer support for JAXB classes. Thus you do not need to implement the writer yourself.
              Also make sure you have @XMLRoot annotation on your Customer class.

                Johannes Hollerer Newbie

                Yes the issue is still the same - i included the resteasy-jaxrs.jar, resteasy-jaxb-provider.jar, resteasy-atom-provider.jar, jaxb-impl-2.1.12.jar, resteasy-jaxb-provider-1.2.1.GA.jar (and some other which he complained at startup) and the jboss-seam-resteasy.jar within my ear project! My classes are annotated with the @XMLRootElement on the class level!


                And the strange thing is - that if i use that class within an manual written code - the transformation takes place without any error.



                This works:



                @GET
                @Path("/list")
                @Produces("application/json")
                public List<Customer> getList();





                But with the definition within the components.xml i get still the error from above !
                I use JBOSS AS 5.1 - could there be any issue ??

                  I believe this is a configuration issue. Take a look at the Seam Tasks example (bundled with Seam distribution). That one uses ResourceQuery set up via components.xml and is tested on JBoss AS 5.1. Or if you provide a reproducible code, I can take a look.

                    Johannes Hollerer Newbie

                    I stripped the example down - still the problem exists - how should i make the code available to you ?

                      Jozef Hartinger Master

                      Can you create a JIRA issue for this and attach the application?

                        Hi,


                        has the cause for this problem been found? I am having the same problem. I started by using the task example and added my own entity classes. When I configure a resource query in components.xml I get the same exception

                        When I try to use a ResourceHome in Java I get the following exeption:

                        }




                        Any idea of what might go wrong here?

                          I cannot see any problem with your class. Could you provide your modified tasks application so that I can reproduce?

                            I managed to solve my earlier problem by starting again with seam-gen this time (before I used the Eclipse based seam tools).


                            I still had to do some other config work as described here:
                            My Link


                            It now works for ResourceQuery and ResourceHome.


                            Then I wrote my own class using AbstractResource and MatrixParameters to return a List of entities. Works fine.


                            But now I am trying to return a simple String List only to get the

                            The getResourceList() Method works fine but the getCountryList() throws that NoMessageBodyWriterFoundFailure.

                              Do you have resteasy built-in providers enabled in the resteasy project web xml?

                                Your problem is related to JAXB. While getResourceList() returns a list of @XmlRootElements, getCountryList() returns a list of Strings (which are not JAXB classes). Therefore, you need to create a list wrapper

                                          this.list=list;

                                  Not sure what's going wrong now.
                                  I managed to work around it by creating a wrapper class for a String which has @XmlRootElement etc. But that is just a hack, I would like to know what is going wrong. It seems to work for others so something in my setup must be wrong.


                                  The context-parm for web.xml didn't seem to make a difference.


                                  Thanks for your help. Very much appreciated.


                                  Regards
