Java EE6 App + EJB in Glassfish 3.0/Netbeans 6.8? - netbeans

Has anyone got this configuration working?
Latest Netbeans, latest Glassfish, I created an EJB project, also an EE Application.
The EJB in itself builds & deploys to Glassfish OK.
Now when I want to reference the EJB, I have to add the EJB jar to the EE Application path, if I don't do this the code does not compile.
But, the EJB jar gets packaged in the App jar and as a result when I try to deploy the app to Glassfish it says:
"java.lang.IllegalArgumentException:
Sniffers with type [ejb] and type
[appclient] should not claim the
archive at the same time. Please check
the packaging of your archive"
How do I tell Netbeans NOT TO package the EJB in the App jar? Or is the problem somewhere else?
btw. if I remove the EJB manually from the JAR then the app deploys successfully (with asadmin deploy), but when I try to run it with appclient, I get a NullPointerException.
Surely there must be a solution to this, I thought Netbeans was for web application development after all...
Edit: I found this:
http://forums.netbeans.org/topic23499.html
Which lists exactly the same steps that I did to resolve the problem.

Here is a solution candidate:
https://netbeans.org/bugzilla/show_bug.cgi?id=183488
Which basically says that Glassfish v3 is seriously broken, and it won't work.

Here is how I got it to work: the EJB and the EE Application MUST BE packaged in an EAR (project), and they MUST BE deployed within the EAR. Deploying the application jar individually WILL NOT WORK (at least not with Netbeans 6.8 + Glassfish v3).

Spring Petclinic (2013 version) doesn't work in JBoss AS 7

I'm trying to run the Spring Petclinic example on JBoss AS 7.1.1. I've imported the maven project from https://github.com/SpringSource/spring-petclinic/ to Eclipse Juno and successfully deployed it, but http://localhost:8080/petclinic/ gives me HTTP Status 404 error.
The only problem I can see from the log is
JBAS011006: Not installing optional component
org.springframework.web.context.request.async.StandardServletAsyncWebRequest
due to exception:
org.jboss.as.server.deployment.DeploymentUnitProcessingException:
JBAS011054: Could not find default constructor for class
org.springframework.web.context.request.async.StandardServletAsyncWebRequest
but according to Spring3.2 and jboss as 7 it's normal behavior.
I've found some advices about modifying the Petclinic sample for JBoss, but all of them are for the old version of the sample, not the updated 2013 version (http://blog.springsource.org/2013/03/21/spring-petclinic-is-on-github/).
The sample works fine with Tomcat 7.0.39.
Update:
The problem only occurs when I run the sample from Eclipse using JBoss. As Andrzej said, building the app with standalone maven and deploying the resulting war works fine.
The problem is JBoss/JBoss Tools use incorrect war name and context root when deploying from Eclipse.
In pom.xml the war name is specified as <warName>petclinic</warName>, but JBoss uses "spring-petclinic" instead. Tomcat, Glassfish, and Weblogic don't have this problem and work correctly with deployment from Eclipse.
The workaround is either to use http://localhost:8080/spring-petclinic/ instead of http://localhost:8080/petclinic/ or configure the context root via WEB-INF/jboss-web.xml:
<jboss-web>
<context-root>petclinic</context-root>
</jboss-web>
The Spring Petclinic (2013 version) works well with Jboss AS7. Tried it with two Jboss versions. What you need is to build app with maven and deploy it to standalone/deployments folder.
Problem is running it from Eclipse Juno.

JBOSS NoClassDefFoundError: org/ejbca/util/InterfaceCache

I got the error NoClassDefFoundError when trying to deploy the EJBCA API in my JSF project. When I deploy it in a simple java project, all goes fine with simple classes and JARs imported in the Java Build Path, but in the JSF that not happens.
I tried to copy the jars that I want from EJBCA folder and put in MyProject\WebContent\WEB-INF\lib and nothing happened.
What must I do?

Eclipse doesn't import all Axis2 jars but project still runs on Tomcat?

When I develop an Axis2 web service on Eclipse, I noticed that Eclipse is automatically copying the classes from the lib folder of Axis2 to the lib folder of the new project. However, not all classes from the lib folder of Axis2 are being copied. Interestingly, the web service runs without any problem when deployed to Tomcat via Eclipse even if some the jars from Axis2 were not copied. Also, when I viewed the temp file of Tomcat, Tomcat seems to generate the jars for the listed modules on modules.list of the web service.
Can someone enlighten me regarding what is happening on this? Why Eclipse doesn't copy all the jars from Axis2? Why can the web service run on Tomcat even without the other jars from Axis2? What are those temp files for? When and why is it being generated?
I tried to run the same project on WebSphere and I am encountering a ClassDefNotFound exception because of the missing jars. My problem was solved when I copied all the Axis2 jars that was not copied by Eclipse to my project. But I'm not comfortable with my solution because Tomcat can run my project even without those jars. Is my solution really the right solution? Or am I missing a configuration setting?
This is just for clarification:
My web service is already running in Axis2. My class loading policy is set to PARENT_LAST. I know that since WebSphere has its own Axis2 configuration, the class loading policy must be set to PARENT_LAST so that WebSphere will use the Axis2 from the project itself. Aside from setting the class loading policy, I did something to make my web service run on WebSphere. I describe what I did above. My question is why such method must be taken?
WebSphere has it's own axis2 configuration as part of its Java EE server spec for JAX-WS. Change your class loading policy to PARENT_LAST and check if that solves your problem.
Edit:
As the original post already states: WebSphere is a Java EE server depending on version it supports its the standard Java JAX-WS web services. Actually web services became part of the standard jdk.
If you use JAX-WS like mentioned in Introduction to JAX-WS or building web services then you don't have to add any 3rd party library for getting your web services running. As soon as you use the non JDK implementation like axis2 you have to package it with your application.
IBM didn't just pack the axis2 into their WAS/JDK, they modified it. I'm not sure what Tomcat delivers, however as long as you use JAX-WS it shouldn't matter. With JAX-WS you don't have any direct import of the org.apache.axis packages. If you use these imports you have to supply the libraries and make sure that yours are loaded.

JBoss Seam Project errors

I have a JBoss Seam project that a coworker created about a year ago. I'm taking over it now and it needs some work done. So I'm trying to setup the project in Eclipse Indigo. Here is the list of things I have installed so far:
JBoss 4.2.2 GA
JBoss Seam 2.2.0 GA
Glassfish v2.1
JBoss Seam Tools Plugin for Eclipse Indigo
For some reason I am not able to build the project to get an ear for JBoss. The errors I have are one in glassfish-builld.xml which says "Target clean does not exist in this project." And then I have errors in a bunch of generic.jsp file (I have no idea what their purpose is). The error for those is that a library for JBoss Seam called org.jboss.seam.wiki.util.WikiUtil cannot be found.
Can someone point me in the right direction to get this setup and running on JBoss?
Also org.jboss.seam.wiki.util.WikiUtil is a class that is a part of... Seam example project that is added to JBoss Seam distribution in examples/wiki directory. So if you really need it you will be able to find it there. But honestly I don't see any reason to put any dependency to Seam examples in project. Consider just deleting / commening out the code that refers to this class becasue it is probably some quick and dirty test code.
Do you want to run it on Glassfish or Jboss?
Did you import an entire eclipse project or create a new one?
I would first check the referenced libraries to see if there's anything missing(Libraries under Java Build Path for Helios, not sure if that differs from Indigo). Add a -verbose tag to the build and check out the output.

How to deploy EJB on server?

I am learning EJB3 from last few days. I have many questions regarding EJB, application servers and deployment of EJB.
To start with, I have created one simple helloworld stateless session bean but I don't know how to deploy it on server. It has single bean class, bean interface and one servlet client. I have used eclipse to develop this project.
None of the books that I read gives step by step details about how to put EJB on server and how to access those beans.
I have JBoss 6 server and I also have Java EE budle downloaded from sun website. Does this Java EE bundle contains Glassfish server? or do I need to download it separately?
Can anyone please give me step by step details of how to put my bean and its client on server (JBoss or Java EE)?
And why do we need to include bean interface class in EJB client code? I mean either we need to keep client and bean in same package or if we keep them in seperate packages we need to import bean interfaces in client code. Am I right?
With Java EE 6, you can package your Servlet and your EJB in a WAR (either package your EJB in a JAR and put it in WEB-INF/lib or simply put all classes in WEB-INF/classes). And to deploy this WAR, copy it to:
$GLASSFISH_HOME/domains/<domain1>/autodeploy for GlassFish v3*
$JBOSS_HOME/server/default/deploy for JBoss 6
With Java EE 5, you'll have to package your code in a EAR.
And if you want to deploy your application from Eclipse (using the Eclipse WTP), you'll have to install the appropriate server adapter. For Eclipse Galileo and GlassFish (there is currently no adapter for JBoss 6 AFAIK), right-click the server view, select New > Server, click on Download additional server adapters and select the GlassFish adapter. Finish to define your new GlassFish v3 Java EE 6 server and deploy your application on it (right-click on your application then Run As > Run on Server). For Eclipse Helios and GlassFish, you can follow the link given by #VonC (manual install) or check this answer (install via the Update Site).
You need to add GlassFish to your Eclipse installation (see GlassFish plugin for Eclipse).
The full process is described here (with the latest Eclipse Helios 3.6M6)
You should export as EJB into your jboss<version>\server/default/deploy folder and then add the build path for it on the servlet's web project. You can "Run on Server" and choose an application server just like you would in any project, no need to export the WAR although if you do that, you're gonna have to re-export your WAR every time you modify your code
AFAIK there's no Eclipse plugin for JBoss 6 but Eclipse provides one for 5.1
