Oracle BEA Weblogic Server 10 "invalid pad byte" error

First of first, BEA has the worst error message ever, it just does not make any sense, maybe just for me!

When switch to a new weblogic domain, we like to copy the configuration files to the new domain in order to reserve some configurations works, such as JMS, JDBC settings.

However, you may get weblogic.management.ManagementRuntimeException: com.rsa.jsafe.JSAFE_PaddingException: Could not perform unpadding: invalid pad byte.

Does this give you any hint that your password-encrypt is incorrect?

You may need to re-encrypt your password in the new domain by using the BEA supplied weblogic.security.Encrypt tool to archive this goal.
java -cp ./weblogic/server/lib/weblogic.jar -Dweblogic.RootDirectory={your domain} weblogic.security.Encrypt {your plain text password}

While dmagent running, it may hold a copy of the olite.key in the memory. So if you change the olite.key in the file system level, it may not be picked up during next action.
Also, the dmagent has the ability to download the new olite.key as it needs, but you may see the username/password challenge window, if you are sure the username/password is correct, just simply click OK, let it try with the new olite.key downloaded by the dmagent. Surprise, it succeeded!
