I have the latest eclipse Sept 2020 ide for java ee installed, I cannot seem to find out how to create a jakarta ee 8 project in eclipse. I have tried Help then Eclipse Marketplace, searched for jakarta, but only result was Glassfish tools.
I usually program in beans, servlet, jsp code and a brand new to trying (attempting) to learn jakarta.
I can't even figure out how to start a new jakarta web project.
Please any help would be appreciated.
You'll need to wait a little bit for the tooling to catch up.
Indeed, when you create a new Servlet in Eclipse, the only option is to use the Java EE, javax libraries. Attempts to change to Jakarta libraries will cause errors.
One trick is to switch your target runtime to a new server that has the Jakarta EE libraries such as the latest Tomcat version (currently 10). But even that has to be done manually, as the Tomcat 10 server is not yet available as a supported server.
Jakarta EE 9 is officially released December 8th, 2020. It's on that date that all the packages are renamed. We may have to wait a little bit for all of the tooling, such as the Eclipse IDE, to catch up.

It's my first day with Java EE and I would like to understand:
How I can set up a Java EE 7 project? and where can I check what Java EE version I am actually using?
I downloaded the latest Eclipse for Java EE Developers (Neon) and am now trying to understand how all these parts fit together.
I ended up downloading Java Platform, Enterprise Edition 7 Web Profile SDK Update 3 as well as a Shell file to install Java Platform, Enterprise Edition 7 SDK Update 3.
I know there is a lot of instructions provided but I would just like to set up my Eclipse environment.
Happy for any help or resource!
You can follow this tutorial http://www.edu4java.com/en/servlet/servlet4.html it's old but it basically the same thing
You have to create a new project (Dynamic Web Project)
The versions of the Facets you choose will determine which Java EE spec version it aligns with
Choose your application server (I personally recommend Wildfly http://wildfly.org/, but the built-in Java EE Preview Server can run Servlets on its own)
And you are ready to go !
I need to develop a presentation layer for an existing Java EE application running on JBoss AS 4.2.1.GA. I have been reading on JSF, Facelets and RichFaces and tried a few examples - some things worked but others didn't because of the limitations of library versions I used, considering the outdated JBoss.
Can someone recommend the direction I need to be heading to get this done as quickly as possible by using the mentioned server? By this I mean the Eclipse tool (WTP, JBoss Tools, ...), type of project, dependencies, ... Also, to shorten development time, maybe also use JRebel?
I know I would be better off using the latest server, but unfortunately it is not an option.
Also, I have installed JBoss Tools for Eclipse Indigo, but for creating RichFaces Project, it requires JBoss EAP 6 or AS 7.1.
I had created applications using JSF 1.2, RichFaces 3.3.3, JBoss Seam 2.0.2 (not required) for JBoss AS 4.2.2.GA. For development was used Eclipse (3.4/3.5) IDE for Java EE Developers. Version of Eclipse is not important. Yes, you need WTP. In my projects seam-gen was used for generating project skeleton. If you don't use Seam you can create Web project.
I'm currently struggling with the project setup while implementing a Java EE 6 application with Eclipse Indigo and JBoss 6. The application server and the IDE is pretty much set in the project. Maven 3 is used and was the base for the setup by using the WELD archetype and creating a WAR.
Now, the problem is, that I'm very disappointed about the development turnaround. I don't have a working automatic redeploying within eclipse and often need to restart JBoss since it gets confused with the new publishing and then is not able to redeploy correctly. This is very frustrating and time consuming. (Plus I feel the smirks behind me from the guys preferring script languages.)
From earlier projects we were using Seam 2 and the project created by seam-gen came with a somewhat decent republishing, although I still had to do a manual application restart whenever I changed Java classes. Then, from playing around with Netbeans 7 and the integrated GlassFish 3.1 I found that automatic redeployment was working ok. And since Java EE 6 is very wide spread, I assume, there must be a better setup than I have now.
So with this post I hope to get some more insight in having a good project setup for fluent development of Java EE 6 based WAR projects on JBoss and eclipse - who can share some best practices?
Thanks a lot!
You should use JBoss Tools plugins for Eclipse. JBoss Tools 3.3M2 is compatible with Indigo and JBoss AS 7 (which is 10 times faster than JBoss 6 for redeploy).
Regarding an equivalent to Seam Gen with CDI, you should really take a look to Seam Forge which is included in JBoss Tools 3.3 now.
Finally I'm using Jrebel to reload class and configuration without restarting the server. But for now it doesn't work yet with JBoss AS 7, so if you stick with JBoss AS 6 it's a goof combination.
This might not be the answer to your question, but if you want Java and fast turnaround look at http://www.playframework.org/ your script colleagues will be astounded.
For Eclipse to work well, use Eclipse Java EE edition and then add the JBoss server adapter.
The usual WTP-tooling then works for automatic deployments etc.
I need a step by step method because I have never used a server like this in Eclipse.
Do you have some installation tips and tutorial links for this kind of configuration?
As mentioned in this old GlassFish FAQ:
What is the difference between SunOne, SJSAS, and GlassFish?
SunOne is an old branding which was replaced by Sun Java System some time ago.
Sun Java System Application Server is the supported version of GlassFish.
Specifically, SJSAS 9.0 PE and GlassFish v1 are the same bits (except for the installer). Similarly SJS AS 9.1 and GlassFish v2 will be the same.
(See also the SO question "eclipse for sun one server for debugging and running application")
So you could rather declare a GlassFish server in your Eclipse.
Actually, at https://glassfishplugins.dev.java.net/, you have a link to download a Eclipse Galileo preconfigured with the GlassFish v3 Java EE 6 runtime.
From there, you can fond some tutorials (like this one) to configure your GlassFish server in Eclipse.
I have the WTP 3.1 plugin installed and have also installed the Glassfish v3 plugin. I am able to register my server.
When I create a dynamic web project, I can see that the maximum dynamic web module version available is 2.5. I then choose the default configuration for Glassfish v3 but, when I look at it JSF, it is not selected by default. When I select it, the maximum version available is 1.2.
I want to use JSF with facelets - does Eclipse support this? I can't seem to find anything helpful on the Eclipse WTP site.
Java EE 6 / JSF 2.0 is relatively new. Most tools are already ready, but Eclipse has to catch up it yet.
The status as far:
IntelliJ Ultimate Edition was early in this. Unfortunately not freeware. Note: the free Community Edition doesn't provide tools for much of Java EE, let alone JSF.
Netbeans 6.8 came a bit later almost full Java EE 6 support, including JSF 2.0.
Eclipse for Java EE planned to support Facelets in Galileo, but it was cancelled and postponed to the successor Helios which is currently in one of its latest Release Candidate stages been released at 24 July 2010. Helios for Java EE will ship with full fledged Java EE 6 support, including JSF 2.0.
As of now, it just works fine in Eclipse Ganymede/Galileo when you select JSF 1.2 and uses JSF 2.0 libraries. You'll only miss some code assistance which may be useful for JSF 2.0, but you can write code as good yourself.
Use Eclipse with JBoss Tools Plugin. It has support for JSF2 and CDI.

Note, that you can do JSF 2.0 development in Eclipse, but not with as much tool support as might come later.
You can always edit xhtml files directly as XML-files (and have the namespaces registered), and have Glassfish deployments. I've done that, with stock Eclipse 3.5.2 Java EE edition, and the Glassfish plugin.
Have a read on http://weblogs.java.net/blog/2009/05/18/using-ide-write-jsf-20-app
It describe in details on how to setup your eclipse for jsf 2.0 development.
