I just started the tomcat and opened my browser and gave http://localhost:8080. But i found 404 error.
I tried running the same in eclipse i got the following error message.
Several ports (8005, 8080, 8009)
required by Tomcat v6.0 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).
What could be the problem?

Tomcat runs fine, but there was nothing to serve on the given URL. There's no ROOT webapp anywhere or there's no welcome file. You need to either deploy a webapp or let the URL point to a valid resource.

A port can be used only once by only one application at time. This indicates that you haven't shutdown the first instance of Tomcat before you run the one in Eclipse which is apparently been configured to listen on same ports.
If you are using windows, probably tomcat is running as a service.
Control Panel -> Administrative Tools -> Services -> Find Apache Tomcat 6
Right Click and choose properties
Startup Type : change it to manual, and hit the stop button.
click, ok and close all windows.
You can now run tomcat from eclipse IDE without changing the ports.
Just go and kill the javaw process.

Port 8080 required by Pivotal tc Server Developer Edition v4.0 is 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 have this error when I run my project in ubuntu (sts,mysql) "Several ports (8005, 8080) required by Tomcat v8.5 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)."
You have to release ports (stop process running on particular port) on which you want to run your app.

The error message says clearly enough. Port 8005 or 8080 is in use by other process. You need to find which process is using it.

I have a SpringMvc based application project hosted in Jetty and managed by Maven3. I want debug program in remote server JVM. So, on the server side I set java options to the Jetty server.
-Xdebug -Xrunjdwp:transport=dt_socket,address=10.0.5.60:50019,server=y,suspend=n
Then start the jetty server.
jetty server listening on the debug port
Everything seems fine. Then I config a remote profile in IntelliJ
IntelliJ remote debug profile
And start Debug, console shows
Connected to the target VM, address: '10.0.5.60:50019', transport: 'socket'
Wow, seems good. Bug things always happens, The breakpoints can't stop when I visit the running code. That was strange!
I promise I have logs to show that the break-point code must been exec-ed.
So, any one can give a hint to me? Thanks for ur great help.
I was trying to change the user who runs the tomcat process.
In process of changing I have added new user and made tomcat run under him.
how now if i ping the tomcat, I get 404 error.
I am not sure how to proceed.
Can I check if tomcat has loaded all the classes ?
Can I check anything else to make sure tomcat loaded the servlets.
Is there anything else I can check to resolve this 404 error.
Thanks a lot
You didn't say what operating system you are using. Look in your tomcat logs directory and verify that tomcat actually started up. A lot of times the log will be called catalina.out. It should say "server starting up in X ms". Also, look at the running processes on your system. There should be a Java process running for Tomcat. You can also use netstat or dig on Linux to see if there is a process listening on a particular port. You can check what port Tomcat should be listening on by looking in the conf directory and looking at the Tomcat server configuration in the server.xml file.
I am getting this error while starting eclipse. I am using eclipse on windows 7
"There is a process already using the admin port 4848 -- it probably is another instance of a GlassFish server.
Command start-domain failed."
I have searched and found that if i put mny hostname against 127.0.0.1 then this problem can be resolve but my problem is that i can't place my hostname in my host file due to our organization internal network security and i can't even edit this file.So i want that this glassfish server stops allocating 4848 port and starts working on another port.
Please help as i got stuck in this issue.
Thanks
The Eclipse plugin contributes its own Glassfish instance that runs only as long as Eclipse runs. Uninstalling your standalone copy is probably a good solution for you. If not, reconfigure the standalone copy to use a different admin port.
A simple Google search will cover that for you. Here's what I have found as the top hit.
