WebLogic is used in EBS R12.2. "weblogic" account is used to log onto WebLogic Admin console and is also used to start EBS services. Its password is encrypted and saved on the file system. Here are two steps in my R12.2 environments to decrypted it.
1. Identify Domain path and boot.preperties file
$ echo $EBS_DOMAIN_HOME
$ cd $EBS_DOMAIN_HOME/servers/AdminServer/security
$ ls
boot.properties
$ more boot.properties
username={AES}mE0mATL4+Lv/gLcIuuuuuuuuu=
password={AES}2kGMi4fcZ7FwYXWIxxxxxxxxx=
2. Run wlst.sh to decrypt the password
$ cd $FMW_HOME/wlserver_10.3/common/bin
$ ls
commEnv.sh config.sh security startDerby.sh stopDerby.sh upgrade.sh wlsifconfig.sh
config_builder.sh pack.sh setPatchEnv.sh startManagedWebLogic.sh unpack.sh wlscontrol.sh wlst.sh
$ sh wlst.sh
CLASSPATH=/u01/app/... ......

Weblogic server password is: webLogicPWD

If you get Java error, most likely you entered a wrong path or a wrong encrypted password/string.
My WebLogic version is 10.3.6.0.210119. It can be found by two lines:
