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

I have 2 Tomcats running in my server: one Tomcat 7 and the other is Tomcat 8.

The configuration file server.xml for the first is:

<Connector port="8080" protocol="HTTP/1.1"
           connectionTimeout="20000"
           redirectPort="8443" />
             ...
<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />

In the second Tomcat I have:

<Connector port="8080" protocol="HTTP/1.1"
            connectionTimeout="20000"
            redirectPort="8443" />
            ...
<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />

When I run the first Tomcat the console shows the following:

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

But the second runs good.I'm using the command netstate -tnao and see that the ports are free.

Solution 
  • <Connector port="8080" protocol="HTTP/1.1"
       connectionTimeout="20000"
       redirectPort="8443" />

    8080 is the port number on which server will run. Only one server (which you will start first) would run. Other one will throw Jvm Bind Exception.

    So, change the port number so that they are unique.

    One you run first server then use netstat command to see the ports which are in use.
