URL for webapp Docker Tomcat IntelliJ

I'm using a Tomcat 9 server in a Docker container to deploy locally a webapp for development purposes. I can connect to my Tomcat using http://localhost:8080/ But I can't find my webapp URL anywhere. My Docker container is deployed from IntelliJ, and I have no URL field in the configuration of the Container.
Does anyone know where to find/set the URL ?

There is no URL to be set, at least not explicitly.
Once you have your application started in a container (either started through IntelliJ IDEA, Docker Desktop (for), command line...) with the port binding configuration (the Bind ports config section in your screenshot), you are only left with the application as if it was started on the host on the mapped port (the first section before the colon : in the port binding).
Which means you can simply access your application on:
http://localhost:8080
following the pattern for a URL: (protocol)://(host)(:port) where:
protocol is HTTP since you mentioned using Tomcat as a web server
host being you local station where the docker daemon is running on
port being the port you chose to map to the started container port

Cant run index.jsp from web aplication

I made Java Enterprise app using Java 15.0.2 and GlassFish 4.1.1.
This is what I got in glassfish output:

Unable to ping server at localhost 4848

Use the ping-connection-pool subcommand in remote mode to test if a connection pool is usable. For example, if you create a new JDBC connection pool for an application that is expected to be deployed later, you can test the JDBC pool with this subcommand before the application is deployed. Running a ping will force the creation of the pool if it hasn't already been created.
Before You Begin
According to Oracle Glassfish admin guide
Before you can contact a connection pool, the connection pool must be created with authentication, and the server or database must be running.
Ensure that the server is running.
Remote subcommands require a running server.
Ping a connection pool by using the ping-connection-pool(1) subcommand.

Why does Port 9721 intermittently refuse connections on Apache Tomcat 8.5 running on Windows Server 2012 R2?

Web Server: Apache Tomcat 8.5
Operating System: Windows Server 2012 R2
Port: 9721
We are running a Web server on our internal network and have about 8500 kiosks connecting through our VPN to a Java servlet that is running on this port: <Server IP Address>:9721
This Web server was set up by a former employee and we are not sure how it was originally configured.
We noticed recently that about 25% of the connection attempts are being refused (Connection Refused error). We found this information by monitoring Port 9721 using PRTG and this monitoring tool is reporting that this port is refusing connections on multiple occasions within each hour throughout the day. I have not been able to find a pattern to the refused connections...it appears to be intermittent.
Our network administrator says it is not a firewall issue, but I have not ruled out this possibility. We have tried to review the "maxconnections" setting in the Tomcat server.xml configuration file, but cannot find the "maxconnections" attribute included in that configuration file. We do not have the Tomcat Manager Application installed on this server that I can find.
How do I troubleshoot and resolve this port connection issue?

Grails https port closes application

Running a grails application with grails 2.4, i specify the server port and https ports (9191 and 9192, respectively) in a run-app command:
grails -Dgrails.env=dev -Dgrails.server.port.http=9191 -Dgrails.server.port.https=9192 run-app -https
which gets the server up and running. I can go to the http port just fine, but when i access the https port, i get the following message and then the browser shows a "could not connect" page:
| Server running. Browse to http://localhost:9191/inventory or https://localhost:9192/inventory
14:35:58,091 DEBUG [DefaultListableBeanFactory:128] {localhost-startStop-2} Returning cached instance of singleton bean 'grailsApplication'
14:35:58,092 INFO [GrailsWebApplicationContext:152] {localhost-startStop-2} Closing org.codehaus.groovy.grails.commons.spring.GrailsWebApplicationContext#26a2bd15: startup date [Mon Aug 24 14:35:17 PDT 2015]; parent: Root WebApplicationContext
It looks like going to this non-default port is closing my application! when i don't specify the port, and the default of 8443 is used, the application works fine. I've upgraded this app from a grails 1.3.7 version and never had this issue, now i can only use 8443 as my port, which doesn't work as we have multiple services on this machine requiring HTTPS.

When not running in "production" mode, whatever the port is for http, if you add one and make a request to that URL, it will stop your application. This is used for killing forked grails processes during development.
Just put a gap between your above ports you should be good to go.

Weblogic 10.3 can not be accessed after enableing Administrator port

I was was following this blog to set up some SSL connection. One-Way SSL with JAX-WS using JDeveloper 11gR1 and WLS 10.3.1
One of the steps mentioned is to enable the Administration port from weblogic console. I did that and change the Admin port. But, after saving everything get missed up the conclose closed and the I could not run the application form Jdeveloper .
The Error message is:
User 'principals=[weblogic, Administrators]' has administration role. All tasks by adminstrators must go through an Administration Port.
**** Authentication error while connecting to application server IntegratedWebLogicServer. Please check settings.
**** Failed to complete start-up of application server IntegratedWebLogicServer.
[Server Instance IntegratedWebLogicServer is shutting down. All applications currently running will be terminated and undeployed.]
[Forcing termination of IntegratedWebLogicServer]
taskkill /F /PID 7480
Process exited.
This blog: SOA OIM integration and WebLogic administration port
discuss this issue BUT under the assumption that I can access the weblogic console. But it is not happening for me.
I am using Jdeveloper 11.1.1.7 and the weblogic 10.3

The problem solved by deleting the system files for jdeveloper. This action will re insinuate the weblogic server. This file is located in my case in the following path: C:\Users\[UserName goes here]\AppData\Roaming\JDeveloper.
