I am trying to migrate my spring MVC based REST application to Jboss 7.1.0. At startup, the Jboss initialisation shows that everything was started up correctly with all war files deployed successfully.

I had quite a few problems getting the integration between Spring MVN and Jboss's RestEasy service and im wondering if this is another conflict between jboss resteasy with Spring MVN.

When i make a request to the REST service i get the following error:

12:52:31,541 INFO  [org.springframework.web.context.ContextLoader] (MSC service thread 1-5) Root WebApplicationContext: initialization completed in 3035 ms

The error does not make any sense and the only thing i recognise from it is the RESTEasy service servlet name. This is configured as follows - which works fine in Jboss 7.0.2

<servlet-mapping>
        <servlet-name>javax.ws.rs.core.Application</servlet-name>
        <url-pattern>/rest/*</url-pattern>
</servlet-mapping>

I have also seen this exception when using RESTEasy on JBoss 7.1.1 (without Spring). It was wrapped like this:

Allocate exception for servlet [project class reference]: java.lang.RuntimeException: Unable to find a public constructor for class org.jboss.resteasy.core.AsynchronousDispatcher

The solution was to exclude all RESTEasy jars from the war. In Maven, you can do this by ensuring any required RESTEasy dependencies are declared with Maven's 'provided' scope, as these are provided by JBoss, and excluding any transitive RESTEasy dependencies (see this link for an example). You can check if you have any RESTEasy dependencies by changing to the directory containing your pom.xml and issuing a command such as:

mvn dependency:tree | grep "resteasy"

If you are using your web.xml for JAX-RS activation, you may also need to switch to the class-based approach demonstrated in the RESTEasy docs. These solutions to this issue are mentioned by a RESTEasy developer here and here.
