I just started to build a new Java EE Web Application based on the new MVC 1.0 Framework which will become part of Java EE8. I tried to run the application on Wildfly 9.0.2.

Setup a Maven Project

To setup a MVC 1.0 Web Application with maven is tquite simple. I Just added the following dependencies into my pom.xm :

<!-- mvc-api -->
<dependency>
  <groupId>javax.mvc</groupId>
  <artifactId>javax.mvc-api</artifactId>
  <version>1.0-pr</version>
</dependency>
<dependency>
  <groupId>org.mvc-spec.ozark</groupId>
  <artifactId>ozark-resteasy</artifactId>
  <version>1.0.0-m03</version>
</dependency>

As ozark is based on jersey you need the jersey-container-servlet. As ozark is based on Java 8 it is also necessary to start Wildfly with JDK 8. Otherwise the war file can not be deployed.

The application class

Next I added an application class with a resurce mapping /api/

@ApplicationPath("api")
public class MyApplication extends Application {
}

This class is necessary to call the application URL like

/myapp/api/hello?name=xx

Here is my controller class:

@Path("hello")
public class HelloController {
 @Inject 
 private Greeting greeting; 
 private static Logger logger = Logger.getLogger(HelloController.class.getName());

 @GET
 @Controller
 @View("/pages/hello.xhtml")
 public void hello(@QueryParam("name") String name) {
 logger.info("set new message: "+name);
 greeting.setMessage("Hello "+name);
 }
}

On the first look the conroller is triggered. But currently I am not able to return the target page (in my example /pages/hello.xhtml)

The reason seems to be that the jersey servlet container will not replace the resteasy implementation for the application.

Maybe someone knows how to solve this problem?

Update 15.Aug. 2017

Finally I solved the deployment issues in Wildfly. To get Ozark running together with Wildfly first you need to add the Jersey Dependencies to your project. So the pom.xml looks like this:

 ....
<dependencies>
 <!-- JEE Dependencies -->
 <dependency>
 <groupId>javax</groupId>
   <artifactId>javaee-api</artifactId>
   <version>7.0</version>
   <scope>provided</scope>
 </dependency>
 <!-- MVC Dependencies -->
 <dependency>
   <groupId>javax.mvc</groupId>
   <artifactId>javax.mvc-api</artifactId>
   <version>1.0-edr2</version>
 </dependency>
 <dependency>
   <groupId>org.glassfish.ozark</groupId>
   <artifactId>ozark</artifactId>
   <version>1.0.0-m02</version>
 </dependency>
 <dependency>
   <groupId>org.glassfish.jersey.containers</groupId>
   <artifactId>jersey-container-servlet</artifactId>
   <version>2.23.1</version>
 </dependency>
 <dependency>
   <groupId>org.glassfish.jersey.ext.cdi</groupId>
   <artifactId>jersey-cdi1x</artifactId>
   <version>2.23.1</version>
 </dependency>
 <dependency>
 <groupId>org.glassfish.jersey.ext</groupId>
 <artifactId>jersey-bean-validation</artifactId>
 <version>2.23.1</version>
   <exclusions>
     <exclusion>
      <groupId>org.hibernate</groupId>
      <artifactId>hibernate-validator</artifactId>
     </exclusion>
   </exclusions>
 </dependency>
  ....
 </dependencies>
....

The important part here is to deactivate the jersey hibernate-validation. This can be don with the ‘exclusion’ tag of maven.

Wildfly Deployment Descriptors

In the next step we need to provide two wildfly deployment descriptors to ensure that the RestEasy Subsystem is deactivated.

1. Deactivate Wildfly JAX-RS RestEasy Subsystem

To deactivate RestEasy add the file “jboss-deployment-structure.xml” into the WEB-INF-folder with the following content:

<?xml version="1.0" encoding="UTF-8"?> 
<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.2"> 
 <deployment> 
  <exclude-subsystems> 
   <subsystem name="jaxrs" /> 
  </exclude-subsystems> 
 </deployment> 
</jboss-deployment-structure>

2. Prevent implizit bean archives without beans.xml

To deactivate bean archives with a beans.xml add the file “jboss-all.xml” into the Web-INF folder with the following content:

<jboss xmlns="urn:jboss:1.0"> 
   <weld xmlns="urn:jboss:weld:1.0" require-bean-descriptor="true"/> 
</jboss>

See also: https://docs.jboss.org/author/display/WFLY8/CDI+Reference

3. Add the bean.xml file

Finally make sure that your web project contain an empty beans.xml file in the WEB-INF folder:

<?xml version="1.0"?>
<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/beans_1_1.xsd"
       version="1.1" bean-discovery-mode="all">
</beans>

Update 18.Sep. 2017

In the meantime the Ozark project worked on a new implementation to make the MVC implementation independend from Jersey. So now it is possible to user Ozark together with Wildfly without changing the configuration. You need to include the following dependencies:

 <dependency>
   <groupId>javax.mvc</groupId>
   <artifactId>javax.mvc-api</artifactId>
   <version>1.0-SNAPSHOT</version>
 </dependency>
 <dependency>
   <groupId>org.mvc-spec.ozark</groupId>
   <artifactId>ozark-resteasy</artifactId>
   <version>1.0.0-m03-SNAPSHOT</version>
 </dependency>
