Why Eclipse Glassfish does not support Eclipse Microprofile ?
And I am confused about Eclipse Microprofile Application,
Eclipse Microprofile Application can be a servlet application(war) nor ony a jar application?
I think servlet-api not nessary for Eclipse Microprofile Application.
I'll start with your last question and work backwards.
You are correct. The Servlet API is not part of Eclipse MicroProfile. So an implementation of the MicroProfile spec need not support servlet. If you take a look at the various MicroProfile implementations you'll see that some of them are derived from application servers, and some are not. Those that have roots in an application server might support servlet, but others might not.
The MicroProfile spec does not specify application packaging or deployment. Just the APIs that must be supported. So some MicroProfile implementations might support war files (likely those with roots in application servers) but others won't. Most of them will support some form of an executable jar and runtime dependency management so that you can create a self-contained, immutable Docker image of your application and its runtime dependencies. In this scenario the value of war packaging is questionable.
Eclipse GlassFish is a Jakarta EE implementation, and the focus has been to deliver a Jakarta EE 8 release. MicroProfile is part of Eclipse, but it is not part of Jakarta EE (at least not yet). So there is no requirement for Eclipse GlassFish to implement MicroProfile (at least not yet).

I need to create a java ee 6 project which contains:
JSF
EJB
JPA
The Web-things should be compiled to a .war file, the ejb to the ejb-jar and overall into an ear file. The application will be deployed to a Glassfish v3.
I was looking for a maven archetype which I can use and integrate into Eclipse. However I haven't found one. Can you help me?
I consider Andy Gibson's Knappsack Archetype as a good starting point for what you are looking for. It gives you certain levels of working projects from a very basic setup to one filled with examples.
Alternatively, Adam Bien's Weblog is always a good place for finding simple solutions as for example a minimal project setup.
The Java EE MVC Security Archetype is a quickstart for websites that want user self registration and security configuration.
You can try it out on Openshift, though sometimes you have to wait a couple of minutes for openshift to load and start the application.
The archetype includes the following technologies:
Java EE MVC web application for Wildly 9 environment
JSF 2.2 and Bootstrap
JPA 2.1
H2DB (H2 Development Database)
JUnit/Arquillian/Drone/Graphene for testing
Java EE SecuritySupported by JBoss/Wildfly Database Module

Is it possible to make a Java EE 6 application deployable on any Java EE 6 Container (like JBoss or GlassFish, etc) without using their modules / libraries?
If for example I want Hibernate or Weld then add these in my Maven pom.
In other words, is there any "vanilla" container or can JBoss or GlassFish be made "vanilla"?
I´m sorry... but to be honest I don´t understand your question.
Java EE applications are in most cases deployable an all containers - as long as they are not using packages or configurations which are specific to the chosen container.
Even if you add libraries in your POM and the applications are packaged as WAR or EAR this should work.
Weld is not needed because the API is part of Java EE 6. If you want to use JPA you also don´t need hibernate.
I am planning to develop a medium to large size web application using JSF (plus PrimeFaces or other) for the view layer and EJB3 for business logic. The reason we've chosen EJB3 over more lightweight JSF beans that might only require a Servlet container (as opposed to an EJB3 container) is for additional EJB3 features like security. Since we are targeting deployment on JBoss AS I was wondering what IDE solution you would recommend. I've seen that both Eclipse and Netbeans support JBoss either out-of-the-box or with plugins.
Or even you can try IntelliJ Idea. All these IDEs has a support for all common servers (including JBoss) so that's really not a criterium for choosing IDE.
It just depends on what you are used to and if you have one of these IDEs already running (with Maven, Ant, SVN, Git or whatever you use for your project) then just go with it:-)
I have a Java EE 6 application developed on Netbeans 7 and try to deploy it on a JBoss 6 instance. The application makes use of JAX-RS but I am not using any Jersey specific aspects, just standard JAX-RS features.
Deployments as a WAR fails because of some missing Jersey classes and deployment as an EAR fails due to org.jboss.deployers.spi.DeploymentException: Only one JAX-RS Application Class allowed
Any idea what the cause of this might be?
What I do not want to do is disable RESTEasy in JBoss, I'd rather produce an application that runs on any Java EE 6 container without tweaks.
Glassfish silently adds Jersey JAX-RS packages to the build. If you uncheck the 'Package' checkbox in the project's lib configuration, the application is packaged without Jersey.
This makes sense, because after all, the target of the deployment might be a non-Java EE 6 container such as 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.
