How to configure Tomcat 9 Spring REST app WAR on Jelastic? - spring

I'm migrating a Spring REST app WAR, that's running fine on a cPanel Tomcat 9 installation, to a Jelastic Tomcat 9 environment. All my content is returning 404's.
My first question is, what to put into the Jelastic Context field, during deployment? I have tried two different names: (1) ROOT- (e.g. ROOT-067) that Jelastic provides, and (2) my preferred webapp name. Both yield same 404 errors. When I study the webapps Directories, in both cases my WAR is correctly unpacked.
My second question is, do I need to modify the Tomcat conf/server.xml or conf/web.xml, that Jelastic generates? I have tried leaving them as originally generated, and making similar changes that I made to both files in the cPanel deployment. With the changed files, the Jelastic deployment fails due to Timeout error after 15 minutes.
Thanks for any and all help!

Usually you don't have to do any changes in your server.xml / web.xml unless you need to have something very specific in it, did you try to set your context name just as ROOT (without index and a dash)? Could you please provide your environment name and a hosting service provider name? I will contact providers tech guys and we will investigate why that problem occurs. Will be glad to help.

How I get IntelliJ UE and Tomcat 9 to run my web application? (Mac OS)

I have searched everywhere for this. I'm sure I have read the information correctly but can't seem to get a full understanding of it.
I used this tutorial to get things going (https://www.jetbrains.com/help/idea/2016.3/creating-and-running-your-first-web-application.html). I do everything step by step but when it comes to running my web app, The localhost shows the official page of Tomcat and not my index.jsp that I have created. I've tried every path combination to try to get my index to show but I have had no luck.
I have done a lot of googling on this and it seems to be that when I run tomcat it reads the files from the webapps/ROOT folder instead of my project folder. How can I get my intellij or tomcat to read the files from my project? I keep reading that its my run configurations but everything looks good to me, and no one really shows what to actually do.
I wouldn't be asking unless I have tried doing this my self for hours. I'm sorry if it is really simple I just can't see it and would really appreciate your help. Thanks in advance

It looks like you already have Tomcat service started on port 8080, therefore IntelliJ IDEA cannot start another instance and perform the deployment.
You need to shut down the service running on port 8080 so that IDE can start its own copy of the server and perform the configuration/deployment on start.
brew services stop tomcat should help in your case.

Deploy on Elastick Beanstack (Tomcat) index page not served

I'm trying to load my Spring Boot REST application on amazon AWS, specifically I'm using the Elastick Beanstack service.
I can configure everything correctly, but the public address (http://socialnotes-env-tomcat.eu-west-1.elasticbeanstalk.com/) does not serve the index html page. In local with
java -jar ...... snapshot.war
everything works correctly, but on amazon aws it seems not to find the index page (even if decompressing the war I see it in the main folder)
It seems very strange and I can not solve, the endpoints seem to work properly and I can also access the static files (http://socialnotes-env-tomcat.eu-west-1.elasticbeanstalk.com/static/assets/images/coffee.jpg)
I followed this guide to create the war file: https://www.mkyong.com/spring-boot/spring-boot-deploy-war-file-to-tomcat/
But I can not in any way make the index page return, I always get a 404.
Can you look in "Logs" of your project at AWS what caused the problem? You can choose option "Last 100 lines" and scrole down. That may help or at least may give some clues.

Websphere application modify web.xml doesn't work

I have deployed applications in Websphere 8.5, and I want to modify web.xml, but it seems not working. What I am supposed to do?
While there are documented ways of updating enterprise application files, those were conceived for multi-server deployments and partly are legacy of the previous decade of monster application servers. They are inconvenient for making changes to local development server and it wastes a lot of time.
Upon application deployment, WAS creates (copies/updates) deployment descriptors in the config directory. Then web.xml is used from that location.
You are probably changing web.xml in the location where original application files are kept, thus no effect. You should change the one in config\cells\<cell_name>\applications\<ear_name>\deployments\<app_name>\<war_name>\WEB-INF.
WebSphere writes a second file named web_merged.xml. If you only update the web.xml and replace it you will not update the runtime file used by the container.
Best result I had was using the single file upload function provided within the Admin console or to use the wsadmin or jacl cmd.
The proper way is to update application via console/script.
But I'm assuming you are editing file directly (very hard to guess from your description, I've asked you to describe your procedure).
You need to restart the application to pick up changes in web.xml. See the Hot deploy in WAR files
Two ways:
Update web.xml with WebSphere Web Console
Update web_merged.xml at the same time, and also update the two files in config\cells\<cell_name>\applications\<ear_name>\deployments\<app_name>\<war_name>\WEB-INF

How to get rid of this error when starting Tomcat

I am adding some things in an existing Android app, which connects to a Apache Tomcat server to get information from a database, but some of the changes required that I also make minor changes on the webapp (changing some database fields).
I had never used tomcat, but managed to do the simple changes here and there.
But when I deployed it, I noticed some errors(see the photo).
How can I fix them ?
The app works regardless of them, but the server takes a few more seconds to start up.
P.S.I read somewhere that this means that the server already has these libs, and doesnt need to use the ones from the lib folder of the app ?

How to deploy Camunda BPM to Tomcat in Jelastic

I would like to setup Camunda-BPM in a Tomcat 7 running on Jelastic. I followed the instructions.
The problem now is that Jelastic does not allow to add the file bpm-platform.xml into the catalina-home/conf directory. So when I start the tomcat I get
...
Caused by: org.camunda.bpm.engine.ProcessEngineException: /opt/tomcat/conf/bpm-platform.xml does not exist. This file is necessary for deploying the camunda BPM platform
Can someone please give me a hint where I can place bpm-platform.xml so that the BPM engine starts?
The directory you're looking for is labelled as 'server' in the Jelastic dashboard - but sadly you cannot upload new files to this directory via the dashboard (only edit the existing ones).
However, you can write to this directory via FTP (http://docs.jelastic.com/ftp-ftps-support), so you should be able to add the file that way.
If you are just using a trial account at the moment, you may need to seek assistance from your hosting provider to add the file there for you manually from their side (since trial accounts do not have public IP, so can't use FTP).
