tomcat server does not start in eclipse - tomcat7

Whenever i try to run my servlet program on the server, it shows this error:
Several ports (8005, 8080, 8009) required by Tomcat v7.0 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).
I tried changing the port numbers but still there is issue with the port number. What should I do?

To resolve this issue,
Open tomcat bin
Execute shutdown batch file for windows
Refresh eclipse and it will solve the problem
Hope this answer is helpful

If nothing works, end all services which are active and using that port. Usualy port number 8080.
Also, you can do this:
right click proj-> properties-> Targeted Runtimes -> tick tomcat version on your pc or create new one

Glassfish claims the port is occupied. Netsat disagree

I have succesfully deployed application on port 8080.
After undeploy and killing all processes "java" and cleaning folders: "domains/domain1/osgi-cache/felix" and "domains/domain1/applications/" then
I tried to redeploy application.
It occured the port is occupied. I could not find that port using netstat (like it was suggested on many other posts) so I guess port should be available.
I managed to deploy on different port (9090). I did again undeploy and rest of actions like killing and stopping domain... it occured the port is still occupied as well and I could not deploy app on port 8080 and 9090 now.
I am using glassfish 4.1.2 and Windows. Anyone have ideas what can I do more?
I also added my hostname under etc/host.
From the description of your post, it sounds like you have tried to follow some instructions intended for Linux on your Windows system. Since you managed to start GlassFish on port 9090, that indicates that the hostname issue does not affect you. The fact that you could not start GlassFish on port 9090 afterwards suggests that you have not shutdown GlassFish properly.
On Windows, it is not always possible to view all Java processes if they were started by another user. So if you have GlassFish installed as a Windows service, then a Windows system user will start GlassFish and the Java process will not be visible to you.
A good way to verify whether or not GlassFish is still running is to visit the endpoint in a browser, in your case http://localhost:9090. If your application is there, then its homepage will show, otherwise GlassFish will serve a 404 which will look a lot like this:
If you manage to get a response in your browser, then you will be certain that GlassFish is still running.
Actually, I did not find answer why the port is occupied. But if someone else found similar issue, this procedure of redeploy works for me:
1: go to admin panel of glassfish (by default :4848). Select application and click undeploy
2: stop domain using console (asadmin stop-domain domain1)
3: start domain using console (asadmin start-domain domain1)
4: go to admin panel(by default :4848), deploy application.
This procedure worked for me, instead of clicking "redeploy" on admin panel.
Glassfish and Windows...

Spring Boot Port Issues

I have created a single web page application using Spring boot and i have configured the port number in application.properties file.
server.port=9991
When I right click my project and click as Spring Boot App it runs fine and when i run it for the second time its throwing that port is already in use.
I am using Spring Tool Suite.
Please let me know why I am getting error.
Error Message:
Description:
The Tomcat connector configured to listen on port 9991 failed to start. The port may already be in use or the connector may be misconfigured.
Action:
Verify the connector's configuration, identify and stop any process that's listening on port 9991, or configure this application to listen on another port.
The first application you started was probably still running when you started oh the second time. Kill the process manually. Look for java processes and kill them.
If I am not mistaken, you can just configure port 0 for your application to let the OS pick a port for you. So you could have multiple instances running on the same box at the same time. Porbably you will encounter more conflicting ports for management etcetera.
I think you are using eclipse IDE. when you run first time your program it will take your current port number. I think you are running your application without stop your old process. simply way in eclipse, there is your application running log. there is cross btn or red square btn click that btn and re run that.

Apeche service of Xampp not install in win7 64 bit

While i am trying to install the Apache service then It shows Service not install. How can i solve this problem?
xampp version:3.2.2enter image description here
That means that apache cannot be currently installed as a service. It happens because the system failed to start apache.
Try to run it pressing the start button, to see if you can get more details about the error.
One of the most common thing is that the port 80 (or the port you have configured to serve web) is being used by another application such as Skype.
In order to solve this, you have to close that application and stop all services using that port and configure the application or service to run in another port.
To see what process is using your port: How can you find out which process is listening on a port on Windows?

XAMPP - Port 80 in use by "Unable to open process" with PID 4! 12

I've tried deleting skype but that didn't work, I've tried turning off the world wide web thing off, IIS off nothing seems to work.
12:51:22 PM [Apache] Problem detected!
12:51:22 PM [Apache] Port 80 in use by "Unable to open process" with PID 4!
12:51:22 PM [Apache] Apache WILL NOT start without the configured ports free!
12:51:22 PM [Apache] You need to uninstall/disable/reconfigure the blocking application
12:51:22 PM [Apache] or reconfigure Apache and the Control Panel to listen on a different port
Open a CMD prompt as administrator and execute the following command:
net stop was /y
Open the Run dialog box (press Win+R), then type: services.msc
Then search for World Wide Web Publishing Service (WWW-Publishing Service) and Web Deployment Agent Service and stop them. You should also disable them.
Start Apache again with XAMPP :)
Link Ref: https://www.sitepoint.com/unblock-port-80-on-windows-run-apache/
Another very easy option is to simply set Apache to listen on a different port. This can be done by clicking on the "Config" button on the same line as the "Apache" module, select the "httpd.conf" file in the dropdown, then change the "Listen 80" line to "Listen 8080". Save the file and close it.
Now it avoids Port 80 and uses Port 8080 instead without issue. The only additional thing you need to do is make sure to put localhost:8080 in the browser so the browser knows to look on Port 8080. Otherwise it defaults to Port 80 and won't find your local site.
This will also require you to restart Apache for the change to take effect.
Voila! Fixed.
In httpd.conf change the following lines and then restart the application:
Listen 80 to Listen 8080
ServerName localhost:80 to ServerName localhost:8080
When you press "Start" the application can still say that you have an error like "Port 80 in use by "Unable to open process" with PID..." but it will still work.
If the error includes "Port 443 in use by "Unable to open process" with PID..." you need to change both httpd.conf and httpd-ssl.conf.
In httpd-ssl.conf change:
Listen 443 to Listen 4433
<VirtualHost _default_:443> to <VirtualHost _default_:4433>
ServerName www.example.com:443 to ServerName www.example.com:4433
Extracted from this article:
Go to your run command and enter:
netstat -o -n -a | findstr 0.0:80
The last number here is the process ID using it. This is most often IIS or other web relates service and is easy to resolve, but every so often (very often it would seem looking around on google) it appears to be PID 4 – which according to the Windows Task Manager is the NT Kernel and System. Not very helpful given killing this will result in a blue screen of death.
The thing hogging port 80 has nothing to do with IIS or web anything, it's SQL Server Reporting Services. Turn off anything that resembles a SQL Server Services and start Apache again, no need for a reboot.
So problems with PID 4 listening to port 80? Check your SQL services and turn them off.
UPDATE -
Comment from #sangam:
Worked at a shot. In my case, it turned out to be SQL server reporting
services. I stopped the service for all the installed instances, and
it worked (without machine reboot).
So I have faced the same problem when trying to start Apache service and I would like to share my solutions with you.
Here are some notes about services or programs that may use port 80:
Skype: Skype uses port 80/443 by default. You can change this from Tools -> Options -> Advanced -> Connections and disable the checkbox "use port 80 and 443 for addtional incoming connections".
IIS: IIS uses port 80 be default so you need to shut it down. You can use the following two commands: net stop w3svc, net stop iisadmin.
SQL Server Reporting Service: You need to stop this service because it may take port 80 if IIS is not running. Go to local services and stop it.
VMware Workstation: If you are running VMware Workstation, you need to stop the VMware Workstation server - port 443 as well.
These options work great with me and I can start Apache service without errors.
The other option is to change Apache listen port from httpd.conf and set another port number.
Hope this solution helps anyone who faces the same problem again.
You might need to stop the "Web Deployment Agent Service"
Press Win+R and type services.msc
Right click on Web Deployment Agent Service and select "Stop"
Restart XAMPP
Also after double clicking "Web Deployment Agent Service" you can make the Startup type to Manual, So that "Web Deployment Agent Service" will not start automatically
As there is comment by #johnkarka on the question, this port is used by SQL Server reporting service as well. After stopping this, Apache started fine.
Go to "SQL Server Configuration Manager"
Click on "SQL Server Reporting Service" and stop it
The funny thing is IIS was working fine in same configuration but not Apache, had to stop SQL Reporting service to make it work on default port (80).
After changing the main port 80 to 8080 you have to update the port in the control panel:
Then click here:
And here:
Then save and restart.
Open Task Manager (Ctrl+Alt+Delete).
Go to "Details" tab.
Sort by PID number.
End process that is using PID number indicated in error.
Restart XAMPP.
What worked for me was stopping the Internet Information Services (IIS). If you are using Windows 7, click on your Start button and in your search box, type "iis". Click on "Internet Information Services (IIS) Manager". When the window pops up, and assuming you've got none of the icons selected, you should just be able to click Stop on the right action pane. My XAMPP Apache started right up. Hope it all worked out for you.
In windows 10, to free up port 80:
in my case, I open "Services" from "Search Windows" (on the left corner on screen), then stop all of SQL server services MSSQLSERVER and it works again
I had this problem too and stoping services using port 80 didn't helped. I resolved it by following this procedure (found on a french board):
Launch RegEdit
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HTTP
Change the value of "start" to 4 (disabled)
Reboot your computer
Not sure how this affect other services, but it solved permanently the issue and so far I didn't see any issue.
Using Windows 10.
If you've SQLServer Reporting Services running locally then you need to stop that also..
I've had the same problem, but in my case Apache was already running and for some reason the XAMPP config tool didn't show that. It happened after I started XAMPP for the first time after the installation. After crashing the other Apache instances all was fine and ports 80 and 443 were free again.
So before making changes to your systeem, make sure something as obvious as the above isn't happening.
"SQL Server Reporting Service" was causing issues in my system, after stopping it, Apache started working fine
I have the same issue, I solved the problem, just disabled
"BranchCache Service" in services.
Somehow windows updates, this service is triggered in startup, and uses 80 ports. When you check via netstat you could see the system is used this but couldnt understand which service is used.
Click services on the Xampp control panel (filename is services.msc, extra info).
First, look for IIS, if it is running. Stop it (stop this service option on the left after clicking on the service name.). Then, this is the main problem, Look for Web deployment Service (not the exact name though it has Web deployment at the beginning.). Stop this service too. Try again and Apache should work.
If you are running Skype, exit out of that too, run Apache, then launch Skype
I've had same problem, when I was installed MS WebMatrix, IIS Server was blocked the port 80 which XAMPP was running on. I tried to find World Wide Web Publishing Service and stop it, but could not find it on list. Best way is changing a port.
Please refer with this
link ref.
For those with ASP.NET, C# or having SQL Server users, If you are using SQlServer OR Visual Studio Your port might encounter. easiest thing you might want to do is on Command> servies.msc and then find SQl Server Reporting Service and then stop it.
if the service is http.sys
You need to change the binded IP address for http.sys
netsh http add iplisten ipaddress=::
Work fine without restart the os.
The Web Deployment Agent Service is deployed with WebMatrix and was the cause of my woes. It may also be distributed with other applications installed using Microsoft’s Web Platform Installer.
Uninstall it solved my problems!
For me usually works:
- Turn off Skype
- Turn off all SQL Server processes displayed in services.msc
- Turn off World Wide Web Publishing in services.msc
It usually works afters you stop IIS Server and Skype
XAMPP - Port 80 in use by “Unable to open process” with PID 4! 12
run the comment in cmd tasklist
and find which the PID and process name related to this now open window task manager
you can also open window task manager by using CTRL+ALT+DEL
now click on the process tab and find the name which using PID and right click on that and
end process
now again restart the xampp
I had same issue. After some googling arrived to this page. Since I guess this error may have various reasons, so listen to my experience:
Xampp red line log:
12:53:54 PM [Apache] Problem detected!
12:53:54 PM [Apache] Port 443 in use by "Unable to open process" with PID 3908!
...
Finally it turned out that I had this line of code in my php codes :
$res = file_get_contents("http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]");
The purpose of this piece of code was to get a mirror of php result from somewhere in my server. But it's just stucked in a loop that gets its own content!
I repaired code:
$res = file_get_contents(str_replace("my_uri.php" , "mirror_uri.php" , "http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]"));
Then I restarted apache ... and that apache error never happened again.
So sometimes searching for probable halting points in your code is a good approach.
In Ubuntu by default, the system will not allow you to occupy privileged ports [ 0 to 1023], other than specifying the port as 80, you need to run XAMP with sudo.
I write this, because i coudn't find answear for the same question.
In my case PID was 2484.
you must find a process or service with this PID:
open cmd (in Windows) and write:
tasklist
Find your PID in this list and read name of process or service.
Now you can kill this using Task Manager
find this name on Process list
click End Process.
That's my case. Possibly you must open services.msc and stop Service with your PID.
On my computer xampp it worked fine :)

How to change the port of websphere/glassfish?

I'm a websphere newbie and would like to change the port number. I read to manual about ports but it didn't say anything about port number 8080 and it says that glassfish is running on 8080. Am I running websphere or glassfish? When I installed websphere a browser started a window saying I'm running glassfish which I thought was another app server. Did I install both?
If you want to change glassfish port on the other hand go to http://localhost:4848 (default port for admin console) and on the menu on the left navigate to:
Configurations > server-config > Network Config > Network Listeners > http-listener-[1|2]
and there you can change the port.
WebSphere Application Server doesn't use Port 8080 by default. If port 8080 indicates that Glassfish is running, then you must have installed and started Glassfish. These are two completely different application servers / products.
The WAS console runs on port 9060 by default, so you may be able to see if you have also started WAS by going to http://localhost:9060/ibm/console. Also, you can check your running processes (via Windows Task Manager, for example) and installed programs (via Windows Programs and Features, or a simple Explorer search) to determine what might be running/installed.
If, after installing/starting WAS, you still want to change your port numbers, you can do this by going to "Servers > Server Types > WebSphere application servers > [appserver] > Ports" (for individual application servers; also these instructions are for WAS 7.0, but should be similar if you're using a different version). If you are using WebSphere Application Server ND, there are actually a number of different processes/application servers running at any given time (deployment manager, nodeagents, individual app servers) that open up ports as well. I wouldn't recommend changing any of the default port values unless you are sure that you have a conflict though.
