Can I deploy multiple WAR archive files to local Tomcat with IntelliJ IDEA?

I have two applications with two separate WAR artifacts. One is a WAR exploded directory for my front-end Angular app, and one is a WAR archive file for my back-end Spring REST api. I'm currently using IntelliJ IDEA to deploy my front-end to a local Tomcat server and was wondering how, if at all possible, I could configure IntelliJ to run my two artifacts on Tomcat simultaneously. I know I can do this by putting both under Tomcat webapps directory manually, but I was wondering if it was configurable in IntelliJ, and if so, how?

Yes, you should be able to do that.
If you are using Ultimate, you can create a "Local Tomcat" run
configuration in Project1, and go to the "Deployment" tab and drop in
the WAR file for your Project1. Then drop in the WAR file from your
other project (call it Project2) as an External Source. You would
then have both WARs in one run configuration.
This is the answer I found out under this link.

Tomcat in Eclipse not starting my webapp

I'm trying to do something which is normally a no brainer. I want to start my webapp in Tomcat from Eclipse.
Here the steps I followed:
Creating the server using the server wizard
Adding the webapp
The server is starting without any problem, but it's not starting the webapp. I should get the webapp starting logs, but I only get the standard Tomcat logs, like it would log if I started it without a webapp. And trying to access the webapp in a browser gets me a 404 error. Any ideas?
Last thing: when I add the war file manually in the webapp folder, it deploys, starts and runs without any problem.
I'm using Eclipse Luna with Tomcat 7.0.55 and the JDK 1.6, on a Mavericks Mac. I'm building my project with Maven 3.
Edit: After some searching, it seems the problem happens at the deployment step. When I look in my target/majrouting-web-1.1.4 folder, I can see my WEB-INF, META-INF, css, img, and js folders. But when I look in my deployment folder in wtpwebapps, only the WEB-INF exists. Still, when I deploy manually (copying the war file in the /webapp folder and starting Tomcat), it's deploying and working ok. The content of the war file seems ok, also. I don't get it.

I faced same problem ,and here is my solution it works for me:
right click the project->Properties->Deployment Assembly->Add..,
select Folder and select the folder that contains the js/css/other resources, and after restart it works.
I encounter this while update eclipse from Kepler to Neon, this step is not required in Kepler. (at least in my side)

Did you added the application to tomcat?

Make IntelliJ 13 run web application from tomcat directory

I'm having issues with running my application through intellij. I would like intellij to not run my application from its own folder (C:\Users[name].IntelliJIdea13...) but instead place my war file or exploded war into my tomcat /webapps folder and run form there. What is happening is i'm having issues accessing resources as my servletcontext points to my tomcat instance by the exploded war is not there, its in Ideas folder structure.
Currently I set CATALINA_BASE in my launch options which allows me to pull the correct keystore to run but that is living outside of the war.
I have tried changing where my artifact outputs too but what ends up happening is I get weird webclassloader errors due to library collision.

Deploying Eclipse Java Dynamic web project on Apache Tomcat permanently

I have a Java web project in Eclipse which I run through Eclipse on Apache Tomcat.
Is there a way for me to permanently deploy the project on Tomcat such that it runs without having to open Eclipse and rather just starting Tomcat?
If yes, then what steps do I need to follow?
*UPDATE*
If I take the .war file and deploy it on another system will it work? Note that I am using a MySql database in this project. So will transferring the .war file also transfer the database?

You package the project into a war file (since it is a web project) and put that one into the Tomcat's webapps folder. The deployment should then happen automatically, when Tomcat is started.

Generate a WAR file within Eclipse. (Properties->Export->WAR File)
Place this file in the {installation}/webapps folder of Tomcat.
It should deploy now.

Deploy Java Web Project on Tomcat without WAR or EAR

I have a Java Web project (Struts + Spring) working perfectly in my localhost. I have to deploy it on my website, but the Tomcat Manager interface given by the webhost says it cannot upload a WAR file due to safety reasons. When contacting the tech support I was told it is not possible to upload a WAR and that I should try deploying my project by uploading the files directly (I have FTP access).
My problem is that no one at the tech support gave specific instructions on where I should put my project files (I don't know if it should be on de same folder the WAR would be sent to) neither how to start/stop it (Will the Tomcat Manager recognize it once I upload the files?).

You can always try to upload a war file to webapps folder of tomcat.
if tomcat is running with autoDeploy set to true it will auto deploy your application.
i think that the same will happen if you upload the exploded war to the webapps, the context will be the name of the directory you put your files in.

Just place your apllication's root folder to the Tomcat's directory webapps and configure tomcat to auto deploy. Restart the server and your application will be deployed.

You transfer the files to the same place as the war file would go - but just as an expanded war.
Whether or not tomcat will recognise that the files have changed depends on the configuration of the tomcat server. I'd just give it a go - transfer the files and see what happens. If it doesn't pick up the changes then you'll need to find out from tech support how to restart tomcat.
