I use tomcat 7 via Intellij IDEA 13. Tomcat home is /usr/share/tomcat7, tomcat base is /var/lib/tomcat7. /var/lib/tomcat7/webapps contains single folder ROOT where I can find initial tomcat webapp with different instructions.
So where can I find my local deployed webapp? or where is the server root folder?
/var/lib/tomcat7/webapps is the place where you should find your local deployed app, right next to the ROOT folder you see.
If it is not there, then there might be some problem in your deployment.
Are you sure you have deployed it correctly?

I want to know how intellij maps an artifact created in the 'out' folder to the webapps of tomcat.
My project is deployed successfully and I am able to see it in the browser. But when I check the webapps folder of the tomcat, I am not able to see my app folder.
I wanted to know how is intellij deploying to tomcat without moving the files to the webapps folder.
I found this question that is similar to mine but the answer does not mention the process.
I read about the different ways that tomcat deploys but couldn't get how exactly intellij is doing it.
I have done a maven project in my eclipse and was generated a war file in my system.I want to run that war file in another system without using eclipse.Is it possible to run without downloading JDK and eclipse..
You can refer the following link to run WAR with tomcat -
Deploy war in Tomcat
or a video - Deploy the war in Tomcat Video
Well, if this suffice your requirement, it is good else please mention the specific issue, if there is that you are facing.
The .war file stands for 'Web Archive'. This is a packaged web application, which can be run by an Application server (Examples: Glassfish / Tomcat / Weblogic, Wildfly)
The process of making an application server run the .war file is called Deployment.
For example, a .war file can be deployed to Tomcat application server (I.E., made to run by tomcat) by simply copying the .war file to the /webapps folder of Tomcat.
Here are the steps to deploy .war file on Tomcat:
Step 1: Build the .war file for the web application.
Suppose that the .war file is "my-app.war".
Verify that the my-app.war file contains the following:
/WEB-INF/ folder and
/WEB-INF/web.xml file
Step 2: Verify the following settings in Tomcat config.
(This step can be skipped if Tomcat was installed with default settings)
autoDeploy : true
unpackWARs : true
(Note: These are default values. These will be set to true if Tomcat is installed with default settings.)
Step 3: Remove any conflicting entries or stale entries from Tomcat config.
For example, if the new app to be deployed is 'my-app', then make sure that the existing config of Tomcat does not have 'my-app' already registered for another application.
This can be checked by trying to browse http://localhost:8080/my-app.
If this link works, then it means that the name 'my-app' was already taken.
Another way to find if the name already exists:
If Tomcat is installed in "C:\Tomcat8",
then the registration for 'my-app' can be found at
C:\Tomcat8\conf\Catalina\localhost\my-app.xml
Step 4: If steps 1, 2, 3 are cleared, then copy the my-app.war file to 'webapps' folder of Tomcat.
If Tomcat is installed in "C:\Tomcat8",
then the my-app.war file can be copied to
C:\Tomcat8\webapps\my-app.war
Step 5: Wait for Tomcat to automatically detect my-app.war file inside webapps and extract it to webapps/my-app folder.
Tomcat usually does this automatically. However, this process may sometimes not work either due to file permissions (Example: User does not have write permissions on webapps folder, or Tomcat is installed to C:\program files, which has read-only permissions) or due to folder being locked.
Try restarting the Tomcat service to fix the issue.
If restarting Tomcat does not fix the issue, then verify permissions of Tomcat service and re-install / execute Tomcat with the necessary permissions.

I am using Tomcat 7.0.50 server.
How can I delete the tomcat cache memory without restarting the server?
You can find how to delete Tomcat Cache here
You can delete the "work" folder under Tomcat Home. Even if it does allow you to delete the folder while tomcat is running, I would guess it will cause troubles to your running site.
If your Tomcat installation is configured to have a ROOT directory for your webapp, you will have to find a path like
/tomcat/base-myapplication/webapps/ROOT/
which contains your deployed webapp.
Just delete everything inside, including sub directories META-INF, WEB-INF, VAADIN etc., and then re-deploy your webapp. This worked for me even with tomcat running, but it doesn't hurt to restart tomcat after deployment.
I have deployed one war to tomcat7 webapps directory.
But when tomcat is starting it runs application twice.
What could cause this problem?
I have already met this case, but it was when I was mapping domain to webapp, but know all the configuration is standart, and there are two instances running.
This can happen if you have a symbolic link somewhere in your webapp directory, that points to a war file or exploded war directory. Tomcat simply follows those links and starts all application it finds.
Also check the configuration in conf/server.xml and make sure you haven't set up any other directories as appBase.
It might be possible that in your webapps directory you might have another war or another webapp already present.
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.
