I've just finished developing a java ee application with tomcat and spring boot and angularjs and mysql on localhost, please can any body help how to deploy this app to run on live server and what are the changes must be done before generate the war ( i meant the porte 8080 and mysql porte) because finally i want tu run my app on http://myserver.com/myapp/ instead of http://myserver.com:8080/myapp/
If you're using Spring Boot, don't use the war option. Build a fat jar instead. That's the more common way of deploying Sprint Boot and it will save you an incredible amount of pain like this. For example, your complaint about ports is (going on memory) solved liked this:
java -Dserver.port=80 -jar some-service.jar
or
export SERVER_PORT=80
java -jar some-service.jar
FWIW, Spring Boot bundles Tomcat with the fat jar.

I'm creating a job in jenkins to deploy a springboot application to Tomcat.
I'm trying to understand why should I deploy an application to Tomcat? Why not just run the application on the server by "java -jar" command?
In my previous workplace we deployed the springboot application by creating a war file and "java -jar" command. We used "kill" to shut down the application and "java -jar" again to deploy a new version...
I understand that Tomcat has a big advantage here and I would like to understand what is it?
Google says me how to work with tomcat but I couldn't find a real explanation why need it except this that says:
It provides a management dashboard from which you can deploy a new web application, or undeploy an existing one without having to restart the container. This is especially useful in production environments.
But what do I have to manage here?
I have a Spring boot application, If I want to run that application locally we can run with spring-boot:run Or by just executing the main class our project is ready to work. But here I want to deploy the same on IIS Server.
I have an angular app, by just adding the path and running ng build --prod is sufficient to run in the IIS but when coming to java I am confused to run the application in IIS.
I dont think so it will work with spring-boot:run as it is using internal tomcat server, But in the IIS how do we need to deploy this application.
i tried it by making package and run it as a service in remote but it is not working.
You can directly install java app inside of Tomcat or docker. You can see this answer for more details https://stackoverflow.com/a/59463209/8684299 written by

P.S. I don't have enough reputation to comment hence I am writing this in answer section instead.
What are the steps I need to take to deploy my compiled jruby rails application(with warbler gem) to heroku Java servers?
I don't know Java so I hope you can help with the actions I need to take. For example, how I deal with the database connection? What configuration I need?
for deploying your Rails application as a war archive you should follow the Java web-app runner guide ... although it does require some Java domain knowledge - mostly around Maven.
probably the easiest thing is deployment using the toolbelt plugin heroku deploy:war --war <path_to_war_file> since it assumes you have packaged the .war on your own locally ...
NOTE: be advised that if you'd follow the migrating to JRuby guide than you'll end up deploying without any .war packaging being involved in the process (similar to how you deploy with MRI)
Hi I am a newbie with Spring MVC and I have a little problem.
I can't deploy this project on a Tomcat server. https://spring.io/guides/gs/securing-web/
I can run the project by running it as an application. And you see everything starting in the console, with a spring boot. And if I go to http://localhost:8080/ I see the right page.
I think this is deployed on an internal Tomcat server, but what do I have to do if I want to deploy it on another server, raspberry pi or a BeagleBone with a Tomcat server installed on it ?
I tried to use the WAR file to deploy on an external tomcat server but that doesn't work because i think its because this project doesn't use a WEB-INF folder and also has no web.xml file.
Thanks.
I guess a drawback of using such an awesome IDE like eclipse is that you miss the point for what happens behind the scenes of an application. I'm a ruby developer so not a java veteran. So I've been coding a project in java and using the spring framework for IOC and MVC. Can someone explain to me what is going on when I select run on server in eclipse? Because eventually I will be deploying this masterpiece of an application to a Linux server. Here is my setup. I am using Spring MVC 3 and the maven plugin in eclipse. In the pom.xml file, I have stuff like latest spring release version, log4j, spring mvc, spring context etc.
I have been testing my application on localhost using the handy option of run on server in the eclipse IDE. The server configuration in eclipse is pointing to the tomcat directory location for where I have installed tomcat 7. Please demystify what happens behind the scenes and what I will need to do if I want to deploy this application on a production server. The more detail the better. Thanks a ton in advance.
Deploying a web application to Tomcat is as simple as this (assuming Tomcat is installed)
Bundle your application in a .war with the correct format.
Move the generated .war file to the /webapps directory of your Tomcat installation folder.
Run the /bin/startup.[sh|bat] script in the Tomcat installation folder.
Note that there are intermediate steps you can do to configure the deployment, like changing your context path. Go through the Tomcat documentation for details.
In step 3, Tomcat will extract the .war contents to a directory in the /webapps folder with the same name as your .war file. It will use this as the context path. The script itself launches a java process by putting the WEB-INF/[class|lib|...] onto the classpath along with some Tomcat libraries.
So Eclipse basically does all the steps above for you.
Ultimately you are deploying an web application that means you are deploying a war file to the server. Regardless of using frameworks like spring, struts anything.
SO a web application request starts from web.xml file. SO for spring mvc application, you are mapping all request coming from browser to DispatcherServlet and then this guy is responsible to manage whole life cycle of your application.
For more details of how MVC works please see
http://docs.spring.io/spring/docs/3.2.x/spring-framework-reference/html/mvc.html
So in order to deploy your application (a war) on server first of all you have to create a war from your source code. You can go to traditional approach to use java given utility like using jar from command prompt or you can use ANT, GRADLE, MAVEN and such build tool that creates war for you in automated way.
Spring is not doing anything extra for you. I believe you to research a bit more on how these tools works.
Once a war is ready for you, you can simply go to tomcat UI and there you will find options to deploy your war.
I hope it helps you.
All the majic happens in two places.
The first is your 'Servers' directory in the root of your Eclipse Package Explorer. These are your server configuration files that Eclipse will use (mostly) when it creates a new server instance.
The second is in the ./metadata/.plugins/org.eclipse.wst.server.core/ file system directory in your Eclipse workspace. This is where the tomcat application is actually deployed by eclipse.
The Tomcat Documentation is pretty good actually and helps explain how to do deployments. FYI, I do not know many people that use the Manager, from my experience most people deploy their applications by hand.
