The tomcat is a well-known Apache licensed web server. There are many stable versions. The one I have been using is Tomcat 8.
Recently, a new NATIVE version is released as is quoted from the Apache website.
The Apache Tomcat is proud to announce the release of 1.2.24 of Tomcat Native.
Could someone explain what the difference is between Tomcat Native and Tomcat? Also, when we refer to a software framework as a NATIVE framework e.g. React Native, what do we really mean?

Tomcat Native optimizes the performance of Tomcat in high concurrency environments.
If Linux has installed APR and native, Tomcat directly supports APR.
Simply put, native is a Linux plug-in used to improve Tomcat concurrency.

I am developing a spring-boot application with the aid of the new ElasticSearch Java Client 8.4.
I need an ElasticSearch server running on docker with same version. Otherwise, some queries may not be performed because of incompatibility issues.
I know that ElasticSearh is no more open source from version 7.10, and has 2 kind of licences.
Question is, how may I implement an Elasticseach server on Docker by using free licence? What should I do at code level?
Thanks
Yes, you can and download the docker image from their website.
docker pull docker.elastic.co/elasticsearch/elasticsearch:8.4.3

I want to develop an external PC application using Java and MsSQL/MySQL.
I want to share it with all people. But I have no idea about how to install MS SQL or MySQL automatically with my Application setup, without a normal manual database installation.
Or is there any other way to develop such an app using "Java + any database server"?
Or is there any best way to success this process with Java?
If you are programming in netbeans you need include the database within netbeans? Here is a guide on how to do this.

i created war.now i need to deploy this war in tomcat.but how do i install tomcat on that remote server.I want to know A-Z how to host java web app on remote server.
I know you have said you already bought a hosting solution, but I have had good experiences with DigitalOcean. They provide lots of documentation on getting started to host web applications and servers. Here is a link to them describing how to install Apache Tomcat on a remote linux server, perhaps this will be helpful.

I used to be able to download a tar.gz version of the Java 8 JRE for Windows, now there is only the installer version. Does anybody know what happened to this or if there is another official Java "portable" download?
Edit: Same goes for Mac OS X, is there a tar.gz version of the Mac version of Java as well?
Ah, I found it. The JDK doesn't have a tar.gz, but the JRE does.

According to https://stackoverflow.com/a/5039371/769384, which clearly states the difference between servlet containers and app servers, it seems that a web container such as Tomcat should not be widely used in enterprise applications.
Lots of libraries would have to be installed additionally, so it's a lot easier to install an app server that provides it.
The question is - do I get it right? Are there any enterprise applications run on tomcat? What would be the benefit of deploying a Java EE (EJB+JPA+JSF+...) on a Tomcat instead of a GlassFish server?
Servlet containers which can be also called web containers don't support EJBs', they only support Servlets and JSPs' along with other related technologies.
If you need to deploy and EJB, you'll then need an application server.
