How can I chose a specific version of Java EE in Eclipse? - eclipse

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 !

Jakarta ee web project in Eclipse ide

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.

Can't install glassfish server in eclipse oxygen

Hi I am using Eclipse Oxygen in Ubuntu 18.4 with Oracle Java 10. I tried to install glassfish server in Eclipse but failed. every time I tried it said java development kit is required instead of JRE. I had given the path "/usr/lib/jvm/java-10-oracle". Even if I put the path as "/var/cache/oracle-jdk 10-installer/",it says "Java installer not found in the specified folder". i am putting the two screenshots here for your reference. Please help.Here are the 2 screenshots for the above two cases
[Note that in this answer I am assuming you are using GlassFish 5.0, which is the latest version]
GlassFish will not currently work on Java 10 due to the JPMS (module system). You need to use Java 8 instead.
You should also be aware that you need specifically Java 8u161 or lower for GlassFish, but the latest release of Java 8 can be used with Payara Server which will work in the same way as GlassFish.
If you really need to use GlassFish on a version of Java 8 higher than u161, then you can use the latest 5.0.1 nightly build

Here is the information about my Development Environment:

Trial version SAP HANA Cloud Platform Cockpit
Please forgive me if the question sounds naive but I'm been a .NET Developer for past few years, and I'm trying to learn SAP Hana Cloud technology.
I've learned that you have to develop code on Eclipse Java EE IDE for Web Developers in order deploy to the Trial version SAP HANA Cloud Platform
I was trying to use Tomcat 8.5 in my local development environment.
How can I add the the Apache Tomcat v8.5 icon taht is missing from the list within the "New Server Run Time Environment"?
The version of Eclipse WTP that supports Tomcat 8.5 is not out yet and is expected in the 1st maintenance release.
If you need it sooner, you can find instructions on how to get it to run in this bug report: https://bugs.eclipse.org/bugs/show_bug.cgi?id=494936

Does glassfish 3.1.2 Open source edition contain all Java EE 6 components?

Does glassfish 3.1.2 Open source edition contain all Java EE 6 components? I'm trying to figure out my project dependencies
Depends on the profile you choose. Java EE 6 Web Profile or Full Platform.
A quick Google search will provide you with a comparison of features/components

Does the Eclipse IDE support JSF 2.0?

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.
