Forget the glassfish password, then reset the password.

Method One: If the existing domain does not have what you need, delete the existing domain and recreate a domain.

找到安装glassfish的目录下的  \bin\asadmin 目录，然后打开asadmin.bat文件，这个文件可能没有显示后缀（bat），双击该文件。  然后输入 delete-domain domain1

如果提示删除成功的话，输入create-domain --adminport 4848 domain1

From now on, remember to create a new domain password.

Method Two: Keep the existing domain, create a temporary domain, and then copy the temporary domain admin-keyfile to the old domain.

%SJSAS_HOME%\bin\asadmin create-domain --adminport 4848 temp

copy %SJSAS_HOME%\domains\temp\config\admin-keyfile %SJSAS_HOME%\domains\domain1\config\admin-keyfile

%SJSAS_HOME%\bin\asadmin delete-domain temp

Forget the glassfish password, then reset the password.
