I forgot the Glassfish3 master-password, how can i reset it?

Question

I forgot the master-password of my Glassfish 3.1.2.2. Is there a way to reset it? I spent a lot of time "googling around" but i didn't find a suitable answer.

Answer 1

There is a backup password that can be used to access the administrator panel even if you've forgotten the main one.

If you navigate to glassfish\domains\domain1\config\ you will find a file called local-password.

The contents of that file can be used as a password to log in to the control panel as admin.

Answer 2

Please follow the below steps:

1. Stop the domain
2. Back up the master password file
3. Create a new domain and save the master password:
   asadmin create-domain --savemasterpassword domain2
4. Remember the password :-)
5. Copy the newly created masterpassword file over the old one
6. Delete the newly created domain:
   asadmin delete-domain domain2

FYI, now you should also know why you want to protect the master password file using file permissions :-)
