An exception occurred while running. null: InvocationTargetException: Connector configured to listen on port 8080 failed to start -> [Help 1]

I am using Spring Tool Suite. I check out demo projects in STS. It works fine without any problem before I installed updates in STS today or I installed Oracle SQL Developer recently.
The steps to reproduce my bug：
In STS, in "File" -> "New" -> "Import Spring Getting Started Content", then check out "Building a RESTful Web Service" this project.
https://spring.io/guides/gs/rest-service/ I go to my project folder, type 'mvnw spring-root:run' (I am using Windows). Then got following error.
I do not if this bug related to I installed two updated in STS today or I installed Oracle SQL Developer recently.
Here is the error:
[ERROR] Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:1.5.6.RELEASE:run (default-cli) on project gs-rest-service: An exception occurred while running. null: InvocationTargetException: Connector configured to listen on port 8080 failed to start -> [Help 1]
Then, I checked out the solution in here:
https://stackoverflow.com/a/27416379/8229192
It works after I kill the task which uses the port 8080.
c:\>netstat -ano | find "8080"
TCP 0.0.0.0:8080 0.0.0.0:0 LISTENING 3088
TCP [::]:8080 [::]:0 LISTENING 3088
c:\>taskkill /F /PID 3088
SUCCESS: The process with PID 1196 has been terminated.
My questions are:
Why will I have port conflict? Because I installed Oracle SQL Developer? How can I know exactly which software is using port 8080 also?
I want to know if I kill the task (A) which uses that port 8080, will it cause an issue when this task (A) run later?
I have checked out other projects (like: https://spring.io/guides/gs/scheduling-tasks/). I did not need to kill the task which is also using port 8080, I just directly run "mvnw spring-boot:run". It works and it does not have port number 8080 conflict. Why? Why some have port 8080 conflict, why some are not? This is very confused me. Thanks.

Oracle-XE, OracleXETNSListener service, uses port 8080 to serve its
Application Express.
You kill OracleXETNSListener service, it has no problem at all because you
use SQL Developer not Application Express. Or you can disable its auto start configuration.
Spring Boot's project, serves web server, uses port 8080 by default, you can run with different port Spring Boot - how to configure port, and https://spring.io/guides/gs/scheduling-tasks is not web serving project so it doesn't use any port.
hope this can help you

build-impl.xml:1045: The module has not been deployed error

Trying to setup glassfish server for netbeans. I started the server and ran the project(default web project) and it gives this error:

Intellij 14 Glassfish Server is not connected. Deploy is not available

I'm trying to get my web app, which was developed and deployed successfully in Eclipse, to run on Intellij, but I failed. So I'm trying to get a basic app to run on Intellij with Glassfish first.
I'm following the steps in this tutorial https://confluence.jetbrains.com/display/IntelliJIDEA/Getting+Started+with+Java+EE+7+and+GlassFish+4.0. However, I can't deploy my app on to glassfish server. When I start the server from Intellij, this message appears:
C:\glassfish\bin\asadmin.bat start-domain domain1
[2015-06-25 10:45:58,857] Artifact Glassfish:war: Server is not connected. Deploy is not available.
Detected server admin port: 4848
Detected server http port: 9090
Waiting for DAS to start .........
Started domain: domain1
Domain location: C:\glassfish\glassfish\domains\domain1
Log file: C:\glassfish\glassfish\domains\domain1\logs\server.log
Admin port for the domain: 4848
Command start-domain executed successfully.
I'm using Java 6 with glassfish 3.0.1 (required by my company).
Glassfish server & deployed apps are running perfectly with eclipse.
I can't find any solution on the Internet. Please kindly help.

I had the same problem and I did the following:
Run my IDE as an administrator in Windows.
Credentials I entered in the glassfish configuration for domain1 were incorrect.
here
I change the user and the password by user: admin and password: admin .Entering the directory:
/glassfish4/glassfish/domains/domain1/config
Open the file admin-keyfile and replace what I was for:
admin;{SSHA256}t6QSpkyxWhpNFiV3RQ+LYgVczWIJVylE3f6akcXTRLJm9MKs983QAA==;asadmin
Open the file local-password and replace what I was for:
6588CB5CBF61A96DB036AC047837A1C4468EC2C4
And ready new user and new password!and Enter the credentials in intellij.
I hope it helps you!

Error while starting GoldFish server: Ubuntu 13.10

I consulted here and here but could not get my problem solved.
When I type this on terminal /opt/glassfish4/glassfish/bin/asadmin start, I get the following result:
Remote server does not listen for requests on [localhost:4848]. Is the server up?
Unable to get remote commands.
Closest matching local command(s):
restart-domain
restart-local-instance
start-database
start-domain
start-local-instance
Command start failed.
Similarly, when I type this /opt/glassfish4/glassfish/bin/asadmin --port 5656 start-domain, I get

The server exited prematurely with exit code 1.
Before it died, it produced the following output:

I sense there is something problem in path /opt/glassfish4/glassfish/bin/asadmin. I am working on my first JSF web application and cannot run glassfish server. I am using Netbeans and ubuntu 13.10.
Can anyone show me the way?
Thank you!

The error messages
java.io.IOException: Couldn't get lock for
/opt/glassfish4/glassfish/domains/domain1/logs/server.log
and
Exception in thread "main" java.lang.RuntimeException: the domain
directory is not writable.
indicate that the user account you use to start the server doesn't have write permissions in your Glassfish domain folder.
To solve the problem either change the permissions or start the asadmin command with a user who has sufficient permissions.
If this doesn't solve the problem, there may be another process which has a lock on your server.log file, but I guess you would have noticed that. To make sure you can run
lsof /opt/glassfish4/glassfish/domains/domain1/logs/server.log
to see if any process is using the file.

Not able to debug webservice code in IntelliJ

I have a window service that I have installed.I have the source code of the application opened in Intelli J.
I made configuration IntelliJ as following
I checked the PID of the service and port it is using.
While running Remote config in Intelli J it is giving following error
4:09:18 PM Error running Remote: Unable to open debugger port : java.net.ConnectException "Connection refused: connect"
Can someone please shed some light on how to debug window service in IntelliJ. It is a job schedule application.
The installService.cmd is as follows
set HOME_DIR=%~dp0
set SERVICE="Service_Name"
SET JAVA_OPTIONS=-Xms256m -Xmx256m
#echo Service name is Service_Name
"pathname\Service_Name.exe" -install %SERVICE% %JVM% %JAVA_OPTIONS% -Djava.class.path="pathname\Service_Name.jar" -Dorg.quartz.properties="pathname/Service_NameScheduler.properties" -start com.org.st.Service_Name -stop com.org.st.Service_Name -out "D:/core_log\Service_Name_service_out.log" -err "D:/core_log\Service_Name_service_error.log" -current "pathname\apps"
set JVM="C:/Program Files/Java/jdk1.6.0_29/jre/bin/server/jvm.dll"

Check the port number. It should be same as in JAVA_OPTIONS & Intellij Idea Debugger remote configuration under port no.

Please append the command line arguments from the IntelliJ debug configuration to the SET JAVA_OPTIONS line, it will be something like
SET JAVA_OPTIONS=-Xms256m -Xmx256m -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=51211
And reinstall the service.

Make sure whatever port you're listening on isn't blocked by a firewall.
