This has been asked before but the only answers I saw were "restart or re-install tomcat" and similar and they're not working.
I'm trying to get a simple Java web app to work. I downloaded the example from a textbook website. The web app compiles with 0 errors but I get the following message:
org.apache.catalina.startup.Catalina start
SEVERE: Cannot start server, server instance is not configured
This is a picture view of the error
Here is images of the run configuration
I hope this helps you guys see what could possibly be going wrong. I tried to install Apache tomcat 9 and 8 and I have both and I switch between them to see if any work but I get the same error each time. I know it has nothing to do with conflicting versions because the error was happening even when I only had Tomcat 9.

I am trying to deploy my web application on my Payara 4.1 server. However I am getting the following error: java.lang.NoSuchMethodError: javax.faces.application.Application.addSearchKeywordResolver(Ljavax/faces/component/search/SearchKeywordResolver;)V
When I google this issue, I find a few people with the same problem, however they were all using outdated versions of Primefaces, but I am using the latest version (6.2) as you can see in the full logs below.
I've deployed my application before but I changed too much at one time so I don't know what triggered this error. However I did not change any of the library's/dependency's as for as I am aware.
If you need more information, let me know.

I eventually deployed my application on a Glassfish 5 server and it worked again, I have no idea why though.
Currently using custom error pages on the Java web application which is great. To cover all bases, when restarting Tomcat after pushing out an update, there is a very minor 30 second delay restarting the Tomcat service which shows the standard Apache 503 error message. It just looks horrible.
I've looked everywhere for where to find this file to customise. Any ideas? The server is running CentOS6 with Apache Tomcat 7 which has been installed via Easy Apache 3 on cPanel's WHM.
I have generated a Recommendation engine in Mahout. I have tested the Engine as a Stand Alone Java program.
Now I want to deploy it as a Web Application and hence I am using Apache Tomcat to deploy this Java Application. But when I execute my program on Tomcat Server, I get the following Error:
I have added all dependencies and tried searching the net also on this but with no success. As I am new to Tomcat, requesting you to kindly help me out in resolving the stated issue.
Any kind of help is highly appreciated.
Thank You

I have recently downloading Tomcat 6 and switch the eclipse I was using to the EE edition.I am having trouble getting eclipse to run the JPA project, and I keeping getting the error message HTTP 404. When I open a web browser and type in http://localhost/8080/ I get the tomcat 6 info page so I think the server does work eclipse cannot connect to it.
I have going into the preferences and and made sure the path to the server in the directory was correct..
If you're using "your own" instance of tomcat you must specify the location in the server configuration view. Take a look at the screenshot :
My instance is located at C:\TOMCT. Hope that helps
