Administrator password reset procedure failed on Weblogic 11g

Question

We run a Weblogic Server 11g, the web console password for the user 'weblogic' is lost.
The password reset procedure described "java weblogic.security.utils.AdminAccount newAdmin newPassword ." does not work, this java class is not found "Could not find the main class: weblogic.security.utils.AdminAccount. Program will exit."
Still i found an encrypted hash of the password in the boot.properties file under /oracle/u01/WLS1031/user_projects/domains/domain_Mumus/servers/AdminServer/security, but it is not easy t decrypt it.
any ideas?

Answer 1

Hm, almost working
1 first run
java -cp /oracle/u01/WLS1031/wlserver_10.3/server/lib/weblogic.jar:$CLASSPATH weblogic.security.utils.AdminAccount John John1 .
the idift file was modified successfuly,
then i changed the boot properties file
username John
password John1
i restarted the server.
I had to make the shutdown with the old credentials. (with the old boot_properties file)
but the server cannot log me in.
here is the log
###########SABLE-AUTH########### lookupPassword / user:John
###########SABLE-AUTH########### lookupPassword / password:null
