I cannot open my GlassFish admin panel it demands user name and password

Question

I'm trying to reach my GlassFish 4.0 console, which is at localhost 4848. I start my GlassFish server from my NetBeans, then I go my port. It starts itself and then it asks me for a password and username. But the problem is that I have just downloaded and run that and I haven't authenticated any password and user and I can't open my GlassFish server admin panel.

Answer 1

if you downloaded your AS instance from Oracle web site(separately from NetBeans)

https://glassfish.java.net/download.html

and start domain from console with

asadmin start-domain domain1

you would not have any troubles with authentication. However it looks like NetBeans puzzles you. You may find a solution here. See Quaternion's answer.
