Is it possible to deploy a java web application using Hibernate and Spring MVC to a simple website cPanel-> File Manager as we deploy a simple php/mysql application?
Thanks in Advance
With Spring Boot you can build jar with embedded Servlet container, so Java runtime has to be available at minimum.
Amount of RAM available on shared hosting PHP services is often pretty low, so may not be enough for your needs. To find hosting for your Java/Spring application, pick hosting services that specialize on Java/Servlets.
Also if you are planning to rely your business on such application you should avoid shared hosting as same machine is aggregated between various users. So aggregated users can degrade performance of your application.
Yes, it is possible to deploy war file into cPanel-> File Manager as we deploy a simple php/mysql application. But for that you required tomcat in file manager . Just zip the .war file and upload in manager directory and just extract that zip file.thats it!

I am building microservices(approx 15 to microservices) project for huge organization, I wants to know is it recommended to go for external tomcat with war file or just use the embedded tomcat of spring boot with jar file. Also I am facing issue after building my project on jenkins how to copy the file from jekins server to my server and run the file there and create and automatic build and deployment pipeline i.e. everytime I push the code it should be automatically deployed.
You need to identify what compels you to go for external tomcat deployment. As SpringBoot provides out of box facility to deploy within the container, it is not required to go for external tomcat deployment.
Besides, if you are going for many microservices, it will be good to have with built in springboot with embeded tomcat. Springboot also provides the facility to use undertow or jetty. I would recommend to use SpringBoot with either embeded tomcat or undertow with docker container for more flexibility.
It will be good if you provide the issues you are facing.
You can check the below link for reference.

I didn't encourage until today companies using Spring Boot and deploying in an external Tomcat.
If there is no requirements from your Infrastructure department, I would go with the embedded tomcat.
JARs vs WARs
I think both have their use cases, like a car vs a truck.
Getting started with jar files is definitely easier, it's provided out of the box. However, using war files in a tomcat has a few perks too:
You can use the "manager" UI to update/redeploy a webapp easely
You can monitor server status, inspect sessions, basically have a look under the hood
You can deploy/update multiple wars independently, which might be handy for larger project
...but there is definitely some learning curve to set things up, and it feels a bit ...old. So it's up to you if you want an easy "jar car" or a whole "servlet container truck". ...or you can also have multiple cars. ;) Each has ups and downs.
Pipelines
Like for any other topic, there are very different ways to achieve this. If you use an extern tomcat, you may configure a "script" user and deploy it like this (or similar):
curl -u username:pwd -d path=/something -d war=file:target/someWar.war https://someurl.com/manager/deploy
...or you can go the other way round and create Docker images, or cloud-init VMs or whatever. Or just a shell script to stop it remotely, upload it and start it.
Depending on your situation, the know how of your team mates, etc, one or the other may be easier.
What are the major differences between a web application deployed as a JAR versus it deployed on an application server as a WAR?
My case is that, I have developed a REST service using Spring Boot and that is packaged as a JAR file. The service may have to handle 500-1000 requests at the same time and I'm working on improving the performance of the service.
From a performance perspective, is it better to install an application server and deploy the application as a WAR rather than just execute the JAR as a standalone process?
Would the application server like Tomcat give more control related to number of configurable threads as compared to its JAR counterpart?
The question is a bit incorrect, as JAR and WAR are simply a packaging format.
SpringBoot uses Tomcat as an embedded server by default, so there won't be a difference between running Tomcat as application server and deploying your application as WAR, or simply running a JAR.
What really matters is your code. If you plan to serve 1000rps, I would highly advice looking at Spring Reactor (as you already use Spring) or Vert.x, to provide as much concurrency as possible.
Not sure if it is this is exactly what you are looking for.
But this link will definitely add a point to the discussion-

They are all ZIP format files, not any differents, just the ext string.
i have just created a web project that contains a bunch of jsp and html pages.i need to know how to Deploy them(or provide access) to client computers using a single server(intranet) and where do i need to install JRE because jsp have java code and sql queries in them which interacts with mysql database.
You just have to install a J2EE container into your intranet and deploy your war file on it.
You can easily do this for example using Apache Tomcat, but there is a lot of other products, free or not, on the market.
Quite simple ! Create its war file using any build tools like maven or ant and deploy it on tomcat server and start your server.
Is it possible to deploy my Spring/BlazeDS/Java application to elastic beanstalk? I'm using MyEclipse and built a Java Web Project with the required jar files etc. Do you need to specifically create an AWS Java Web Project - reason I ask is the options to include the BlazeDS files aren't there - so I'm wondering if Spring / BlazeDS is even supported? By default the turnkey blazeds runs through Port 8400 - so I imagine there are some additional tasks required to configure the endpoints to work through port 80?
Gracias!
Take a look at this example. Will be trying something similar over the next few weeks.

BlazeDS is not a standalone application, it consists from a bunch of jar files which should be added to your web application. You will also need to declare a servlet in the web.xml file. I wrote an article a couple of years ago how to add the blazeds jar files to a java web application (and what to configure), you can take a look here.
The Web Start Developers Guide states
All application resources must be retrieved from the JAR files specified
in the resources section of the JNLP file, or retrieved explicitly
using an HTTP request to the Web server.
Storing resources in JAR files is recommended, since they will be cached
on the local machine by Java Web Start.
Now, I have some resources I want to dynamically load after my application has been started (for example OSGi bundles). I can do this using plain HTTP, but I would like to make use of Web Start's support for local caching and versioned/architecture-specific resources.
Is there a way to download additional jar files from the original code base (as specified in the application's jnlp file) using the Web Start infrastructure?
Or alternatively: is there already an established way to integrate OSGi and Web Start that would relieve me of the task to install bundles from the Web Start server?
If you make your application in itself an Equinox-based OSGI application, you can web-start it with all the addition bundles you need.
This article "WebStarting Equinox OSGi Apps" can give you a good introduction on the required settings.
All bundles have to be deployed as signed JAR files
You need a feature that contains all the necessary bundles
When exporting the feature, make sure that PDE creates a JNLP (Java Network Lauching Protocol) file (a checkbox in the export wizard) for this feature
Provide a root JNLP file for you application
Deploy your application to a web server and make sure that the web server is aware of the application/x-java-jnlp-file mime type
He also has an OSGI demo.
I haven't tried it but look at the javax.jnlp.DownloadService API
