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.
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.
I have a tomcat 7 instance running on EC2. The port that tomcat is running on is its default, 8080.
I wanna start tomcat in debug mode, so I started tomcat with the following command :
sudo service tomcat7 start -Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n
I have 8000 port opened in my security group. But when I try to remote debug using eclipse, it gives me a Connection refused error. Any clue what I am doing wrong ?
Thanks..
I don't think that you can put the debug options as arguments to the service command.
Assuming you installed the standard tomcat7 package using yum, edit the file /etc/tomcat7/tomcat7.conf and add this line in it:
JAVA_OPTS="-Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n"
Then restart the Tomcat service.
i tried to apply a remote debugging session with Eclipse to a Windows XP remote pc. So i configured a Windows-Connection in "Debug Configuration" for a "C/C++ Remote Application". But it gives me the following Error message:
"Daemon failed to launch server on IP_ADDRESS using port 0.
Connection refused. Make sure that the DataStore daemon is running on
IP_ADDRESS"
What is the probleme here? Why is a "DataStore" needed, where to get it if it's necessary!?
To connect, a RSE Server has to run on windows box. This invokes the necessary daemon which eclipse wants to connect to.

How do I solve the WAMP and Skype Conflict in windows XP?
My issue is both are working simultaneously when I try to start WAMP
This alert is displayed:
'could not execute menu item(internal error)...'
Generally
If you have installed Skype with WAMP and if you run Skype before WAMP, you can not get WAMP Apache running. Because both use port 80, there is a conflict.
So before running WAMP be sure that your Skype is disconnected. You can log on Skype after you started WAMP .
In Skype if you click "tools " then "Options > Advanced > Connection" or "Connection options ..." and connection down the left,,
un-tick the check-box : "use port 80 and 443 as alternative incoming ports"
The problem should be fixed
In your Case
You might want to backup Wamp's data (don't forget Mysql and www directory), uninstall the WAMP and install fresh WAMPServer again.
In skype >>
Go to Tools -> Options -> Advanced -> Connections and uncheck the box "use port 80 and 443 as alternative".
