Resteasy (or not Jersey - JAXRS implementation) on

I have a web application with a restful web service APIs. The application is now developed and works perfectly on Glassfish Server (3.1.x).

As implementation of jax-rs the webapp use Rest-easy, because present features that are no present at Jersey.

Now, it is necessary to deploy the Web application in WebLogic 12c, specifically in weblogic 12.1.2. But it seemed impossible to do so. Weblogic uses Jersey for restful services and gives conflict if it is to use a different implementation jax-rs. Then the question... is it possible to use an implementation of JAX-RS Jersey different. (in my case RestEasy).

Eventhough, the web.xml archive is configured for using the RestEasy Servlet, still show errors like if is used Jersey (<BEA-101216> <Servlet: "Jersey" failed to preload on startup in Web application: "pruebaRestWL-1.0-SNAPSHOT") and ( <Error> com.sun.jersey.spi.inject.Errors>).

The error is:

web.xml (This is the configuration necessary for Resteasy and work in GF)

<web-app xmlns="http://java.sun.com/xml/ns/javaee"

</web-app>

One of the approach that i try was disabled Jersey on WebLogic. I try with removing jersey libraries used for weblogic in ORACLE_HOME/oracle_common/modules.

jersey-client-1.17.1
jersey-core-1.17.1
jersey-json-1.17.1
jersey-multipart-1.17.1
jersey-server-1.17.1
jersey-servlet-1.17.1

But i have this error: weblogic.application.ModuleException: java.lang.ArrayStoreException: sun.reflect.annotation.TypeNotPresentExceptionProxy

<17/12/2013 10:07:15 AM CST> <Error> <Deployer> <BEA-149265> <Failure occurred in the execution of deployment request with ID "1387296431330" for task "0". Error is: "weblogic.application.ModuleException: java.lang.ArrayStoreException: sun.reflect.annotation.TypeNotPresentExceptionProxy"

Edited: Share a little maven project with only one Restful service and configured for using RestEasy. This project work in GF.

Link for download a Maven Project for test de behavior

Can test with de follow URI. GET.

    Here is working solution on WebLogic 12.2.1 and WebLogic 10.3.6

    Changes in pom.xml
         <dependency>
            <groupId>org.jboss.resteasy</groupId>
            <artifactId>resteasy-jaxrs</artifactId>

    Changes in web.xml
        <!-- A comma delimited list of fully qualified JAX-RS resource class names you want to register -->

            <param-value>com.***.RestServiceClass</param-value>

            <param-value>/rest</param-value>

   @POST
   @Path("/doJob1")
   @GZIP

   {
      return "Ok";
   }
...

It is possible to deploy RESTeasy and make use of it. Make sure to setup your weblogic.xml correctly so to isolate the classpath. There is no need, and in fact you should not, disable the Jersey module.
