Wildfly 10 or higher, JavaEE7, EJBs and RESTful-services

[inkimannen]

Hello,

I have an application, maven multimodule, that has the following modules.

1. module-parent
2. module-ear
3. module-ejb (handles the db-connection, in my 'ServiceBean'-class )
4. module-web (restful-services)

I am able now to deploy the ear-file to Wildfly 10, access the Restful-services in the web-module and make use of the db-connection implemented in the 'ServiceBean'-class.

All is fine there. The configuration in the web.xml  is a bit 'hairy' I guess.

I found a restful-client / restful-service at howtodoinjava (as a proof-of-concept to upload large files , up to 6GB) , those project is available in this repo.

I hope that my README.md-file is uptodate, if you would like to try this out and ask for improvements if needed.You can deploy the service in Tomcat, upload a file with the TestClient.java.

As you can see in the pom.xml the project has dependencies on org.glassfish.jersey ( making this statement, it is my hypothesis that these dependencies are giving me problem later on)

What I would like to do, is to replace the current 'module-web' with a new web-module ( the web-project in the RESTfulServerClient-repo )

I can call the '/hello'-endpoint.

Doing the following addition to the JerseyService-class (adding the EJB-bean to be injected) the 'bean' variable on line 16 is always empty.

@Path("/upload")
public class JerseyService {

  private final static Logger logger = Logger.getLogger(Service.class);

  @EJB
  private ServiceBean bean;

  public Service() {
  }

  @GET
  @Path("/hello")
  public Response tst() {
  logger.info("@GET /hello");;
  logger.info("ServiceBean is "+bean);
  return Response.status(200).entity("service ok").build();
  }

my web.xml has the following content

<servlet>
   <servlet-name>jersey-serlvet</servlet-name>
   <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
   <init-param>
   <param-name>jersey.config.server.provider.packages</param-name>
   <param-value>se.nrm.bio.mediaserver.rs</param-value>
   </init-param>
   <init-param>
   <param-name>jersey.config.server.provider.classnames</param-name>
   <param-value>org.glassfish.jersey.media.multipart.MultiPartFeature</param-value>
   </init-param>
   <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
   <servlet-name>jersey-serlvet</servlet-name>
   <url-pattern>/rest/*</url-pattern>
</servlet-mapping>

So the injections does not to work now, it works in my original module-web(4) where I am using a set of different setup.

I can see the ejb:s in the wildfly admi-interface, so the ear has been deployed but the restful services seem not to be able to fetch them.

The reason why I am not using the above setup is that I am unsure on how to write a restful-service&restful-client using the below dependencies ( any suggestions ?)

    <!-- this should be the same URL pattern as the servlet-mapping property -->

        <servlet-name>resteasy-servlet</servlet-name>

        <servlet-class>

            org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher

        </servlet-class>

    </servlet>

</web-app>

I hope that you are able to give me some advice here.

and/or pinpoint me to a good book/course on JavaEE 7 or higher ( and how to deploy in Wildfly, maven ) .

best, i
