glassfish error - process already using port 4848
I have searched for this problem and i have seen a number of topics. None of which really helped me or gave me a clear answer.
I am running glassfish on a mac and this is the first time i have used it.
I downloaded the .zip version and moved the unzipped folder into my documents folder. I have navigated to the glassfish3/bin and tried to execute the command
This gives me the error below.
There is a process already using the admin port 4848 -- it probably is another instance of a GlassFish server.
Command start-domain failed.
If i just enter asadmin i get the options to exit or get help, but when i try and start the domain i get the above error message. Could some help me with a clear answr on how to resolve this?
