Here s one more option to try if none of the efforts above helped  You might be using Eclipse from a Shared Drive  for eg  H    If so  move copy it the entire Eclipse directory to C  and try again   My Eclipse could not open ports for Tomcat server  with the above error   nor even connect to internet  I also tried another Tomcat plugin  Sysdeo  which failed to open the ports too   These are the options I tried   Check and Kill Other Tomcat Instances   In command prompt  netstat -ano and check if any other processes are using the conflicted ports  Find the PID and kill it Try starting the server again    Change Tomcat Ports in Eclipse   In Eclipse Server tab  double click the Tomcat instance  This will open the configuration tab  Under Ports  change the port numbers   for eg  18080     Kill java exe and javaw   In Task Manager  find and kill java exe and javaw  see https   stackoverflow com a 25334782 4212710 and https   stackoverflow com a 26136890 4212710  Try starting the server again    See my other answer for Eclipse not connecting to Internet  https   stackoverflow com a 37246087 4212710

The problem often arises when Apache Tomcat fails to terminate  properly  even though a shutdown instruction was sent  In my case  using Tomcat 8  this happens with annoying regularity  Luckily  you can use Windows PowerShell and the netstat command to create a simple script to kill the process   The following PowerShell script will parse the output from netstat to find any process that is listening on 127 0 0 1 8005  extract its PID and then kill that process   netstat -a -o -n      select -skip 4          a      -split    3     New-Object  PSObject  -Property   Original    Fields  a              Fields 1  -match  127  0  0  1  8005            Write-Host  Killing PID     Fields 4         taskkill  F  PID    Fields 4      If your server xml configures Tomcat to use a different port or IP  edit the regular expression on the script s fourth line accordingly   Finally  I should point out that the situation is better on Linux because you can instruct Tomcat to save its PID to a file at startup-time and use a switch to force the shutdown  later - the shutdown script for  nix systems already features the ability to kill the process and the sleuth-work with netstat is not required

In my case  it was giving me the error  Port 8005 required by Tomcat v8 0 Server at localhost is already in use  I changed 8005 port in apache-tomcat-8 0 39 conf server xml but changes were not getting reflected  Then I did these changes from eclipse  by double clicking server and modifying the port from 8005 to 8006 and it works     Before putting 8006 I checked in windows shell if this port is available or not  By executing following command   netstat -a -o -n   findstr 8006

You ve another instance of Tomcat already running  You can confirm this by going to http   localhost 8080 in your webbrowser and check if you get the Tomcat default home page or a Tomcat-specific 404 error page  Both are equally valid evidence that Tomcat runs fine  if it didn t  then you would have gotten a browser specific HTTP connection timeout error message   You need to shutdown it  Go to  bin subfolder of the Tomcat installation folder and execute the shutdown bat  Windows  or shutdown sh  Unix  script  If in vain  close Eclipse and then open the task manager and kill all java and or javaw processes    Or if you actually installed it as a Windows service for some reason  this is namely intented for production and is unhelpful when you re just developing   open the services manager  Start   Run   services msc  and stop the Tomcat service  If necessary  uninstall the Windows service altogether  For development  just the ZIP file is sufficient   Or if your actual intent is to run two instances of Tomcat simultaneously  then you have to configure the second instance to listen on different ports  Consult the Tomcat documentation for more detail

If you are running on windows try this in the command line prompt   netstat -ano   This will show all ports in use and the process id PID   of the process that is using that port  Then Ctrl Alt Del and open Task Manager to see which process is that   You can then choose either to close stop it or configure your server to use another port  To check if the new choosen port  let s say 8010  is available do this   netstat -ano   grep 8010   If it does not return any lines then you are fine   To change the port go to the Server view  open server xml and change the port there  Mine has this entry   Connector port  8010  protocol  AJP 1 3  redirectPort  8443

Easy way to solve your problem   The server may already be running in another process  or a system process may be using the port  In order to kill that port  do the following   1  Download TCPView only 285kb  from following link   http   technet microsoft com en-in sysinternals bb897437 aspx  2  Extract folder and start TCPView application   3  Right click on java exe because 8009 8005 ports are commonly used by java process  and select End Process option   this would stop another process easily     NOTE  Running TOMCATPATH bin shutdown bat may not shutdown Tomcat when it contains some demon or unmanaged        threads  In such cases TCPView works fine without any issues
