Glassfish Server start-domain domain1 won't start

Question

I recently downloaded Glassfish 4.0 and I want to use it in NetBeans for making some Web Applications, but when I want to start the domain1 (asadmin> start-domain domain1) I keep getting this error:"There is a process already using the admin port 4848 -- it probably is another instance of a GlassFish server". Any clue what could be the problem?

Answer 1

Glassfish could not resolve the host name. Diagnose the problem (on Linux) as follows:

1. Open a Terminal.
2. Type hostname.
3. Type: ping $(hostname)

If the ping command fails (could not find the host), then add the host name to /etc/hosts. This can be accomplished as follows:

1. Switch to root: sudo su -
2. Type: echo "127.0.0.1 $(hostname)" >> /etc/hosts
3. Kill GlassFish
4. Restart GlassFish

Answer 2

your system using port 4848 that is why. when glassfish starts its need three port numbers one for administrations, one for http applications other for https.

so in you system 4848 is already reserved by some program or server.

Or you can change default port number as per your need like below. type in command prompt.

To change the HTTP port to 10080:

• asadmin set server.http-service.http-listener.http-listener-1.port=10080

To change the HTTPS port to 10443:

• asadmin set server.http-service.http-listener.http-listener-2.port=10443

To change the administration server port to 14848:

• asadmin set server.http-service.http-listener.admin-listener.port=14848
