Having issue with Tomcat when I run in a eclipse - eclipse

I am novice in java I have installed Tomcat and it runs fine in a browser but when I run in a eclipse its showing error like
Several ports (8005, 8282, 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 would like to mention one thing I am not authorized to login with admin account I have tried lot to stop the already running stuff through command prompt and i followed this link Deployment error: Starting of tomcat fail
however I am getting the same error is there any way to solve this issue.
Thank You.

Some other process is using one or more of the ports needed by tomcat (8005, 8282, 8009). Probably an old instance of tomcat. Kill it, then try again.
You can run netstat -abn on windows or netstat -apn on Linux to figure out which process is listening to these ports.

How do I stop Apache/Tomcat server on localhost://8080?

I keep getting errors when trying to serve files locally. I am using Tomcat on port 8080.
When using Eclipse, I get the following error message:
Several ports (8080, 8009) required by Tomcat v8.0 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).
Question
How do I stop the server on port 8080 if I don't know which process started it?
Try to go with a web browser to:
localhost:8080 or 127.0.0.1:8080
and
localhost:8009 or 127.0.0.1:8009
There you could see which service is running on those ports.
Then it will be more simple to understand what you have to stop.
EDIT:
You could use a prompt and the command:
netstat -b
-b it will show the name of the executable running on a port.
For understanding how it works here a good explanation.

Netbeans IDE8 Glassfish 4, GlassFish Server: Administrator port is occupied by null

I just downloaded Netbeans IDE7 with the Glassfish 4.
I just made a project to test it out and see how it goes, and I got this error right from the start:
Could not start GlassFish Server: DAS port is occupied while server is not running
[location]: Deployment error: Could not start GlassFish Server: DAS port is occupied while server is not running
See the server log for details.
BUILD FAILED (total time: 1 second)
I have reinstalled it three times, with the Glassfish and without and then later add it to Netbeans, i changed the domain.xml name="admin-listener" port="4848" to something different
i did this cmd code netstat -aon | find ":80" | find "LISTENING" and closed the programm.
i ran as administrator i think i did almost everyting but it wont simply run, and it keeps returning to the same error
usually i would have given up but this software is required for a school project.
i will try everything.
i hope someone can help me.
Thx in advance
You have to find the process that has taken the port you need. You can try finding it by running the terminal with the command:
netstat -aon | find ":80" | find "LISTENING"
Find the information you need and than kill the process with specific PID in Task Manager.
I hope you find this useful,
Thanks.
A few points:
Why not download NetBeans 8 that also includes GlassFish 4?
Assuming that you have successfully figured out that no other process is listening on port 4848, then Which version of the JDK are you using? Can you try JDK 7 if you are using JDK 8?
Looks like you are not alone - see NetBeans bug 237477.
Note that this isn't the only problem. I run on a Mac and can use the asadmin start command successfully on the remote server. IF I try to start it from NetBeans, it gives me this message.
One hint might be that the domain.xml file is set so that the listening port is 9090, the properties screen for the remote server, which I entered 9090 for, tells me the HTTP port is 23043. I can't edit it. Everytime I try to create that remote server it sets it to this value. The server will run fine if I start it by hand on the remote server, but NetBeans doesn't think it is running.
This occurs because I had to select domain2 because NetBeans says domain1 is already registered on my local machine. I wanted to have a local domain1 and a remote domain1 that are identical so I can test locally, and then deploy remotely.
This error message could be misleading, because it is the same when IP adress of glassfish server in netbeans settings is wrong (not port).
By my experience with this over win 8.1 + Netbeans 8.0 + Glassfish 4.0
The problem resides in permission of folder in windows that block the server execution
I solve the problem changing the permission of the glassfish/domain/domain1 folder for xxxx/user to totalcontrol
If this not solve your problem, try launch the server over console:
asadmin start-domain --verbose
And read the exceptions to try solve the problem.
-EDIT:
Reading other post to try help:
like this: Glassfish server started failed in netbeans 6.9
Or check your firewall:
allow >> C:\Program
Files\glassfish-X.X\glassfish\modules\glassfish.jar
In my case when using the command
netstat -aon | find ":4848" | find "LISTENING"
I noticed that one process was occupying this port. When checked what it was I noticed it was VMWare NAT controller, because I previously had configured a network adapter to listen to this port.
Just stopped all VMWare related services (in my case I didn't need them for development purposes), and solved the problem.
Go to Task Manager -> Services -> Stop Process whose PID IS 3136,2268,2468 ,23.... and near Range in PID. All processes near to the web server's PID.
It works for me on Windows 8.1 pro & Windows 7.
I had the same error message.
Turned out it was caused because my firewall blocked port 4848
May be late but I solved this issue by deleting the app server from the Netbeans and by adding it again. In my case Netbeans 8.2 and Payara 4.1 instead of Glassfish.
If you changed the host of Glassfish server then set it to localhost it should work.

What is veewee waiting for when it's waiting for ssh login?

When veewee is displaying the following message, Waiting for ssh login on 127.0.0.1 with user veewee to sshd on port => 7222 to work, timeout=10000 sec what exactly is it waiting on?
As far as I can tell there is a ssh server on port 7222 on the host that veewee has put up and it's waiting on that. This means that something in the guest is going to connect back to it. However, I can't figure out what that thing might be - and thus I can't debug further.
Further details
I'm trying to build a virtualbox image for vagrant with the CentOS-6.3-x86_64-minimal template. My steps:
bundle exec veewee vbox define 'ejs-centos6.3-1' 'CentOS-6.3-x86_64-minimal'
wget http://mirror.symnds.com/distributions/CentOS-vault/6.3/isos/x86_64/CentOS-6.3-x86_64-minimal.iso
bundle exec veewee vbox build 'ejs-centos6.3-1'
The CentOS install appeared to run without error but it's stuck waiting for the ssh login.
You're right, there's a Ssh server on listening on port 7222, but it's on the guest (VM), not the host.
The host (Veewee) is waiting to connect to it. This SSH service is supposed to become available when the VM install process finishes, that's one of the steps used by Veewee to assume that the setup went fine and that the VM is ready.
If Veewee blocks and never gets this SSH connection, I think there could be multiple reasons:
VM setup went wrong and something prevents it from finishing successfully. Check Veewee output and the Virtualbox VM graphical console that should have opened when launching vewee box build.
There's something preventing your host computer to connect to the VM at the network level.
The VM image doesn't have Sshd installed, and/or the veewee box configuration files (in veewee/definitions/ejs-centos6.3-1/) miss instructions to install the ssh package
You should try to login to the VM using Virtuabox console window and check if there's an ssh package installed (rpm -qa | grep openssh-server) and a process named sshd running.
I've run Veewee against Centos 7 built with GUI on and it stuck on anaconda asking for source of packages. I've checked the ks.cfg and it was pointing to dead resource (404). After pointing to valid url it went through.

Tomcat 7 won't start on eclipse Kepler

I've installed eclipse Kepler with JAVA EE plugin on ubuntu.
Then I installed Apache Tomcat/7.0.35, but when I start the server from Servers tab, I get this error message :
Several ports (8005, 8080) 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).
And when I open this link http://localhost:8080/ it works fine.
How can I solve this problem ?
Run netstat -aon and look for ports 8080 or 8005 and kill the process with
taskkill /f /pid (pid of process)
if your running linux or mac you enter top and look for the process and run:
kill (pid of process)
Then just restart the server

Can't stop or restart JBoss AS 4.2.3 as a service in Fedora

i have a little issue with a Jboss AS 4.2.3 . I'm developing an application in Seam so i'm using Jboss as server. In the client company they have a Jboss AS 4.2.3 installed on Fedora and configured as a service, so it starts automatically on boot machine with PostgreSQL. So, if i run chkconfig --list i can see Jboss here as a service.
But the problem is when i try to restart, stop or start this service (i have root permissions) using this command:
service jboss stop/restart
But i don't know what happens that looks like it doesn't find the Jboss AS instance that's running because i get this message:
JOBSS_CMD_START = cd /opt/java/jboss/bin; /opt/java/jboss/bin/run.sh -c default
No JBossas is currently running
But it's running because if i enter localhost:8080 on a browser it loads the Jboss page. The server admin of the company doesn't know also why the service can't restart or stop or start and only i know that he followed this tutorial to install and configure JBoss AS:
thewiki4opentech.org/index.php/How_to_install_JBoss_AS_in_CentOS_/RedHat/_Fedora
Also, i tried with
/etc/init.d/jboss stop
And i get the same output. If i use
/opt/java/jboss/bin/start.sh -c default
It tries to start a second instance of Jboss AS but it gives me errors because is trying to use the same ports as already started Jboss instance.
And it's difficult to me because i'm connecting remotely using Teamviewer and i want to deploy an EAR but i can't because i can't restart the service to extract the ear. So i wanna ask you for help if you know why the Jboss AS that's running can't be stopped or started using service jboss stop.
As aditional info, i'm using the config to access Jboss apps from other machines (using 0.0.0.0) and the server has a static IP. The config of my hosts file is this:
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
192.168.1.106 entertechserver.localdomain entertechserver
#::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
Regards.
Well, i think that i found the answer. The server admin copy the script run.sh to /etc/init.d/ but we saw that there's another script named jboss_init_redhat.sh that i think is optimized for redhat/fedora systems, so we used this script to copy to /etc/init.d/ and it works!! Now when i stop it gives me the next output:
JBOSS_CMD_START = cd /opt/java/jboss/bin; /opt/java/jboss/bin/run.sh -c default -b 0.0.0.0
waiting for processes to stop
Really i haven't seen the difference between both scripts yet but it will be intersting to take a look.
Regards.
