How to Resolve the "Java.Net.Bindexception: Address Already in Use: Jvm_Bind" Error

How do I resolve the java.net.BindException: Address already in use: JVM_Bind error?

Yes you have another process bound to the same port.

TCPView (Windows only) from Windows Sysinternals is my favorite app whenever I have a JVM_BIND error. It shows which processes are listening on which port. It also provides a convenient context menu to either kill the process or close the connection that is getting in the way.

java.net.BindException: Address already in use: JVM_Bind, in spite of no running port

Probably there is a system process listening at that port. If that is the case, you need to change your port in server.xml file.

Address already in use: JVM_Bind java

Address already in use: JVM_Bind

means that some other application is already listening on the port your current application is trying to bind.

what you need to do is, either change the port for your current application or better; just find out the already running application and kill it.

on Linux you can find the application pid by using,

netstat -tulpn

Tomcat : java.net.BindException: Address already in use: JVM_Bind

The failure isn't due by the port on which the HTTP connector listens, but the "shutdown" port (usually 8005), which is already taken.

You configure it using the port attribute of the <Server> element:

<Server port="8005" shutdown="SHUTDOWN">
...
</Server>

In most cases it is safe to disable it setting the value to -1. This will eliminate also a security threat: an attacker can shutdown the server by sending the characters SHUTDOWN to port 8005.

java.net.BindException: Address already in use: bind

As the error message clearly says: The port is in use.

The netstat output shows there is a connection to BNI-PC:4848. This is the port the Glassfish Admin Frontend should run on, this means there is already an instance of Glassfish running on your computer.

Also, if something is running on port 8080, Glassfish won't start with the default settings.

Changing the debug port doesn't help you, this has nothing to do with the other two ports.

You should close Eclipse and then kill all remaining Java processes via the task manager to solve the problem.

If you really want to change the ports, make sure that Glassfish is not running, open domain.xml inside ../glassfish4/glassfish/domains/domain1/config/ and search for 8080 to change the main http port and search for 4848 to change the Glassfish Admin UI port.

Hint: You can use netstat -a -b (required admin rights) to see which process is using the ports.

java.net.BindException: Address already in use: JVM_Bind null :80

Setting Tomcat to listen to port 80 is WRONG , for development the 8080 is a good port to use. For production use, just set up an apache that shall forward your requests to your tomcat. Here is a how to.

java.net.BindException: Address already in use: JVM_Bind when I start Jetty in eclipse mars

WARN:oejuc.AbstractLifeCycle:FAILED
SelectChannelConnector@0.0.0.0:8080 FAILED: java.net.BindException:
Address already in use

I had the same problem. In my case i tried to run jetty server on windows 8. When i execute mvn jetty:run command had the error on port number 8080. My port no 8080 was running by malware(sysnetwk.exe) after i killed the process(sysnetwk.exe) running on 8080 jetty server started. it works fine now
If anyone has this problem they can follow below steps

you need to find which process running on port no (in my case port no 8080)
c:\ Windows\system32>netstat -ano | findstr 8080
TCP 0.0.0.0:8080 LISTENING 6772
Kill the process using PID
c:\ Windows\system32>taskkill /F /pid 6772
Success: process terminated.

If you can't kill the process using cmd prompt then you can use task manager(ctrl+shift+esc) to kill the process
