I've seen an answer to diable the org.wildfly.unsupported.skip.jakarta.transformer property by putting true but I dont know who to do this with steps. Can someone please tell me the steps to do this. I'm trying to achieve this solution.
Hot to disable WildFly 26.0.1 bytecode transformation from javax to jakarta packages
You should not need to disable bytecode transformation in WildFly 26 unless you are using WildFly 26 Preview. WildFly 26 is still Jakarta EE 8, while WildFly 26 Preview is Jakarta EE 9.1.
If you're using Jakarta EE 8 it's best to stick with WildFly 26 and not use the Preview edition.

Hi I tried to install tomcat9.0 on Eclipse but I got "unknown version of tomcat was specified" and the "next" button is dimmed. Any idea to fix it?
Tomcat 9 is not the only version that explicitly supports Java 8: If you check this page, you will see that "Supports Java version: 8 and later", which in this context means, that it officially supports only Java 8 and above. It does not mean however this is the only one supporting Java 8. Theoretically, you should be able to use any Tomcat version, in practice a.
Tomcat 8 will work perfectly: well since it supports Java 7 and above. The majority of people with a Java8 + Tomcat combination are using Tomcat 8. Tomcat 8 also has Eclipse WTP support.
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 anyone please give me the main difference between JBoss AS 7 and WildFly 8?
I'm going to start a very important project and I have to choose between JBoss AS 7 and WildFly 8 (for this project I'm going to use GWT, JPA/Hibernate and jBPM 6).
WildFly 8 is the next iteration of the JBoss application server after JBoss AS 7 / EAP 6.
Basically:
JBoss AS 7.x = JEE6
JBoss EAP 6.x = JEE6
WildFly 8.x = JEE7
Red Hat typically backports security fixes from newer versions into older versions, Red Hat also typically releases "feature packs" that allow you to access newer features/specs.
So if it is a very important project and you do not need JEE7 specs, you may want to use JBoss EAP which is the productized version of JBoss AS 7.
Otherwise you may want to use WildFly if you need the more cutting edge specs and features.

See JBoss AS / WildFly versions history for more details.
WildFly is the new name of JBoss AS so that the company JBoss and the application server JBoss cannot induce confusion anymore.
Think of WildFly 8 as JBoss AS 8, just with a different name.
JBoss 7 is an implementation of JavaEE 6.
WildFly 8 is an implementation of JavaEE 7.
The JBoss application server is the "commercialized" version of the community Wildfly application server. Red Hat offers support contracts for JBoss and has a long term maintenance schedule for JBoss.
The versions are also different. JBoss EAP 6 corresponds to Wildfly 7.
For Java EE project I use JBoss AS7.1 and Eclipse IDE. In Eclipse I can see the current version of CDI under: Project -> Properties -> ProjectFacets -> CDI
How do I change the version to CDI 1.1 ?
If you are prepared to upgrade your application server, then make the switch to WildFly 8 or higher (WildFly is the new name of JBoss AS). CDI 1.1 is part of the Java EE 7 spec, which is implemented in WildFly 8.*, GlassFish 4.*, et al. If you are not able to upgrade your application server, you might be able to drop a JAR of an implementation of CDI 1.1 into your build, but it would probably be better to upgrade to EE 7 if you can.
I'm about to start working on a project to be deployed later this year and would like to use JDK8. We use JBoss EAP for production but the latest JBoss EAP, 6.2 (based on JBoss AS 7.3) does not yet support it.
From a compatibility perspective, is it ok to start deploying in Wildfly8 now (which supports JDK8) with the expectation that later this year the corresponding EAP will come out?
It all depends on your application to be fair.
WildFly 8 support EE7 and EAP6 EE6, so it is up to you to decide what level of Java EE you need/want.
In future WildFly will be base for EAP7, which version of WildFly will depend on what is available at the time when "productivization" will begin.
As for Java 8 support goes, EAP 6.3 runs on Java 8, currently it is at Beta release which you can grab from http://jbossas.jboss.org/downloads/ with GA release coming soon.
