This is caused because there is a database running on your computer.
In my case, it was an Oracle data base. By default, everytime you start your computer, the services of the database automatically starts.

even i faced the same problem.
The possibility of this could be usage of same port by two or more application/process.
In Some cases you can use different port number which will avoid this problem, but in other case you have to manually kill the process with help of command prompt.

The command to kill is,
In your command prompt first enter this command

C:\Users\A611003>tasklist

After this you can able to see list of process running with process ID. 
For example,
<a href="https://i.stack.imgur.com/EEkEZ.png" rel="nofollow"><img src="https://i.stack.imgur.com/EEkEZ.png" alt="enter image description here"></a>

From this select the process you want to stop, for example consider the process id 304 is your server and you have problem with that.
Then enter this command.

<pre><code>C:\Users\A611003&gt;Taskkill /PID 304 /F
</code></pre>

This will kill that process now you can clean, publish your server and start it.

Note: If you fail to add /F in the above command it does nothing. It is the force kill. you can also try/? for list of available options.

The solution worked for me is to kill whatever process is running on port 8080 (in my case it was oracle) and then restart your server and run your project again.
Open Windows PowerShell and type these commands:
<code>netstat -ano | findstr &lt;Port Number&gt;</code>
<a href="https://i.stack.imgur.com/Jpmoe.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Jpmoe.png" alt="enter image description here" /></a>
<code>taskkill /F /PID &lt;Process Id&gt;</code>
replace 'Process ID' with whatever number is shown in your terminal
<a href="https://i.stack.imgur.com/7IsS7.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/7IsS7.png" alt="enter image description here" /></a>
After this, restart your server and run your project again and it should work.

I am trying to access localhost:8080 but it is showing me I need to enter user name and pass word.

While working with servlets I was tring some security features and till some time i did not see and of these pop up windows asking for authentication. 

I tried to enter the password that I was playing with but non of those are working. Is there anyway i could get out of this problem? <a href="https://i.stack.imgur.com/3GmFT.png" rel="noreferrer"><img src="https://i.stack.imgur.com/3GmFT.png" alt="enter image description here"></a>
