I am a new java learner and choose idea as my ide.
Now I am confused of the meaning of "Web exploded" as the image shows.
Exploded = unpacked. Normally web apps are deployed in war/ear archives (essentially zip). Using exploded deployment allows updating application without redeploying or restarting the server. The server doesn't need to unpack the web application when it's deployed, it just uses the files that are present in the directory.
This way you can test your changes much faster when developing and debugging, then you can build war/ear artifact and deploy it on the production server.

I have a war which I deployed on a productive tomcat server. Now I have made another updated war which I want to deploy on the server in the place of the old war. I know I can just replace the old war with the new war, but I was wondering if there is a way to do this without breaking the application for the users?
Note: I am using a Jenkins script for deploying the war
If you are working with Load Balance or Cluster, you can use the Blue Green deployment methodology.
I have several web services packaged as a .war file that is build by ant. I would like to test these wars as an Eclipse Dynamic Web Service. All the examples and help I've seen are based on Eclipse building the war file but I've not seen anyone deploy an externally build war file to an Eclipse hosted Tomcat service.
I am aware that you can create a war file from a Eclipse Dynamic Web Service, but since we have multiple developers using multiple IDEs and even multiple platforms the wars need to be created via an IDE agnostic Ant script.
Wars were developed so that a service could be portable. I just want to plug one into the Eclipse Tomcat Web Server to test.
Thank you but I don't want to create the war from Eclipse (export), nor import a war into my eclipse as a project. (I know how to do these and they don't do what I want). I want to deploy a war into a Eclipse/Tomcat service to test.
Thanks for reading this.
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.
How does IntelliJ automatically deploy the webapp in tomcat?
Just wondering as after the webapp has been deployed and run, there are no traces of the web app in the tomcat folder. (Not even the servlet classes' files).
Does it create those file and delete straight after execution?
Thanks in advance.
IntelliJ is deploying the exploded WAR which exists in your compilation target directory (for my project, it's target - it could be out for yours, depends on if you're using Maven or some other dependency management application), in the process explained at this Wiki link.
So, the artifact always exists in your target or out directory. If it didn't exist, then Tomcat would pitch a fit.
I have been using IntelliJ IDE (version 5.1) with Tomcat server (version 5.5) to build my Java web applications. I'm now trying to migrate my project to Eclipse IDE.
When I run my web application from IntelliJ IDE, it creates a exploded directory inside my web application project folder and then starts the server and runs the web app. (i.e. no WAR files and no copy to tomcat\webapps folder).
But in Eclipse IDE, it usually deploys the web app inside Tomcat's webapps folder.
Is there any way to deploy web applications to a exploded directory outside the Tomcat server, from Eclipse IDE?
There is pretty neat Eclipse plug-ins you can install that will allow you to do that.
Have a look at Plug-in, tutorial and from Sysdeo.
Sysdeo is the one that both Apache and IBM suggests.
There are actually quite a bunch of these plug-ins from different vendors.
The trick is to find the one that best suits your needs.
Hope this helps.
