Re: [Resteasy-users] Classpath issue with Jackson 2

[Bill B. <bb...@re...>]

In JAX-RS 2.0 clients do not scan your classpath for classes annotated 
with @Provider.  So you have to manually register the JAckson2 provider.

Resteasy does provide a way to package up built-in providers.  If there 
is a META-INF/services/javax.ws.rs.ext.Providers file, resteasy will 
register all classes listed in this file. This is a resteasy specific thing.

So, what you could do instead is load the resteasy integration for Jackson2:

         <dependency>
             <groupId>org.jboss.resteasy</groupId>
             <artifactId>resteasy-jackson2-provider</artifactId>
             <scope>provided</scope>
         </dependency>
