i have this error when I run my project in ubuntu (sts,mysql) "Several ports (8005, 8080) required by Tomcat v8.5 Server at localhost are already in use. The server may already be running in another process, or a system process may be using the port. To start this server you will need to stop the other process or change the port number(s)."
You have to release ports (stop process running on particular port) on which you want to run your app.

The error message says clearly enough. Port 8005 or 8080 is in use by other process. You need to find which process is using it.
By checking this, please refer, you can find a tool that suitable for you.

I'm trying to run my projects in eclipse but whenever i run my project its showing
Address already in use: JVM_Bind Exception.
How to solve this one?
You have another process that uses the same port as your project. Try to identifiy the port and try to find it using netstat -ano | find ":80" cmd line (if you are a windows user). the "80" is port numbe. That's my best hint because you don't share enought details.
On Windows
1. Hit Ctrl-alt-delete and look at open programs. Look for java.exe.
2. From a command window, run netstat -an. Check which ports are in use. You can identify which application is running this way, then close it from the Task Manager.
3. List item
If you intend to run both JIRA and Confluence on the same machine for trial purposes, you will need to change either of the listening port number from the default (8080).
If you are using older versions of JBoss, chances are that MS Office or MS OfficeCommunicator are engaging port 1098 and 1099. If you don't want to shut down these tools then your only option is using a different bind address
I am new to play framework. I have an existing play application. I am supposed to understand it and make enhancements. So I am running the application on my windows 7 machine. It runs fine. On using debug(activator -jvm-debug), the jvm starts listening on default port 9999. Till this point everything is fine. When I start debugging it as a remote java application from my eclipse, the process listening on the port 9999 gets terminated. I have been monitoring the activity on Windows Resource Monitor. I have no clue where to check for the issue. Any help will be greatly appreciated
Thank you
The common things that you can check for a generic situation like
Message: “Failed to connect to remote VM. Connection Refused”
1) Have you setup the remote VM to accept connections?
java -Xdebug -Xrunjdwp:server=y,transport=dt_socket,address=10000,suspend=n yourServer
2) Is there a firewall in the way? Are you specifying the correct host / port?
In my java web application i am using certain ports like 1025,10..,10.. .after restarting tomcat in server .the port used by tomcat project are not closing ,it is still open
how to close the port manually using putty or WinSCP file editing
any solution for closing the port
You can use Nirsoft's CurrPorts utility to manually close TCP connections. That said, it is not necessarily the right thing to do...
Get to the tomcat directory and run shutdown.sh script and now you can re-use those ports. Hope this helps, if not comment the response.
If this doesn't solve.
Find the process id or pid using netstat command.
Verify that pid using lsof if linux or pfiles for solaris
Kill using kill
hope this helps. In a server there will be multiple processes running some of which you might not know, those processes might use your ports(sharing). While using netstat watch for CLOSE_WAIT status (these are killer handing processes) you must get rid of them in a safe way
I just started the tomcat and opened my browser and gave http://localhost:8080. But i found 404 error.
I tried running the same in eclipse i got the following error message.
Several ports (8005, 8080, 8009)
required by Tomcat v6.0 Server at
localhost are already in use. The
server may already be running in
another process, or a system process
may be using the port. To start this
server you will need to stop the other
process or change the port number(s).
What could be the problem?

Tomcat runs fine, but there was nothing to serve on the given URL. There's no ROOT webapp anywhere or there's no welcome file. You need to either deploy a webapp or let the URL point to a valid resource.

A port can be used only once by only one application at time. This indicates that you haven't shutdown the first instance of Tomcat before you run the one in Eclipse which is apparently been configured to listen on same ports.
If you are using windows, probably tomcat is running as a service.
Control Panel -> Administrative Tools -> Services -> Find Apache Tomcat 6
Right Click and choose properties
Startup Type : change it to manual, and hit the stop button.
click, ok and close all windows.
You can now run tomcat from eclipse IDE without changing the ports.
Just go and kill the javaw process.
