RichFaces Showcase and TomEE

[ccaspanello]

Has anyone sucessfully got RichFaces to work with TomEE?

I've downloaded the Showcase from https://github.com/richfaces4/showcase/tree/4.3.2.20130513-Final and used Maven to build the project using:  mvn clean package.  However, when I run the application I get the following stack trace in my log.

I've done some research and saw this link https://community.jboss.org/thread/221213.  I attempted the suggested solution did not have any success.

We are trying TomEE 1.5.1 and RichFaces 4.3.2.  I know there is a new version of RichFaces, however, we need to still support IE7.

The errors we are getting are the following:

The *-tomcat6 war of the showcase is meant for a tomcat (sevlet container) deployment.  You will want to use a Java EE deployment for TomEE (ie. doesn't bundle the jsf jars, etc.).  I'd recommend trying the -openshift war.

Yes, our showcase profiles names need some cleaning up...

Thank you for your response Brian, I will give that a shot today and let you know how we make out.

So I've attempted Brian's solution and I am happy to say I did get a little farther.  At least the application deploys.  However, I am still not able to get the showcase to work.  I am getting the following error:

HTTP Status 500 - java.lang.NullPointerException

Class from "GrepCode" Build 4.3.1.CR1

private static final class PersistenceServiceRef
{
  static final PersistenceService PERSISTENCE_SERVICE = (PersistenceService) FacesContext.getCurrentInstance()
                .getExternalContext().getApplicationMap().get("persistenceService");
  private  PersistenceServiceRef()
  {
  }
}
 
 . . .
 
public void execute(FacesContext context) throws FacesException
{
  try
  {
    lifecycle.execute(context);
  }
  finally
  {
    PersistenceServiceRef.PERSISTENCE_SERVICE.closeEntityManager();
  }
}

I am guessing this has to do with the DataSource and PersistenceContext not being configured properly.

Can you advise on what configuration you guys are using for the showcase and if I need to include any other jars (ie, maybe the in memory Hibernate DB if that is what your using).

Thanks,

Chris

Right, so the openshift profile gets the EE dependencies right for tomee, but uses the JBoss AS versions of the persistence.xml.  Try using the tomcat one:

https://github.com/richfaces4/showcase/blob/master/src/main/resources-tomcat/META-INF/persistence.xml

Additionally, there may be some things in the web.xml that are important for tomcat:

https://github.com/richfaces4/showcase/blob/master/src/main/webapp-tomcat/WEB-INF/web.xml

If you get this working, and are up for it, a Github pull request with a working TomEE profile would be very much appreciated!

[ccaspanello]

Thanks for your reply Brian.  I copy/modified the openshift profile to create a tomee profile.  I also copied in the persistence.xml from the tomcat profile like you suggested.  However, in doing so I came across a few issues.  The first issue was NoClassDefinition errors relating to Hibernate.  This was expected as TomEE uses OpenJPA instead of Hibernate.  I went to the TomEE site and followed their directions for hooking up Hibernate (http://tomee.apache.org/tomee-and-hibernate.html).  When I cranked up the server the NoClassDefinition errors went away; however I still got the same NullPointerExceptions as described above.  I then decided to take another approach; I reverted the hibernate libraries and changed the persistence.xml to use the OpenJPA implementation.  This resulted in the same NullPointerException as described above.

I then decided to abandon trying to get the RichFaces Showcasse to work on TomEE.  Instead I used Netbeans to create a basic Web application in which I hooked up RichFaces to it.  When I launch TomEE I was able to see a "rich:panel" with all the appropriate styling.  This was a good first step.  However, when I tried to do a basic HelloWorld AJAX call (see below) I get a different NullPointerException:

java.lang.NullPointerException

        {
            message = "Hello World!";
        }
        else

Any thoughts?

That's a shame you can't get the showcase to work, but it does highlight a problem with our current showcase.  Namely that it tries to hard to demonstrate Java EE technology, rather than simply showcasing our components.  The Java EE interop is valuable, but is better left to dedicated developer examples.  This is something we are addressing in our re-vamp of the showcase for RichFaces 5.

As for your more simple application, can you post the full stacktrace?

[bleathem]

I built a sample RichFaces application from the org.apache.openejb.maven:tomee-webapp-archetype:1.5.2 archetype, and adding RichFaces dependencies to the pom. The app deploys and runs fine, using an a4j:commandButton on the initial page.

See the Readme for instructions on building the above application, and running it in an embedded TomEE container:

https://github.com/bleathem/tomee-richfaces-app/blob/master/README.md

Note however that RichFaces Push (RF-13178)  and Resource Optimisation (RF-12801) both currently have issues when run on OpenWebBeans.
