Cause:

Security logger Jar files from the modules directory is corrupted/missing. This can be caused because of improper file transfer.

com.bea.core.weblogic.security.logger_1.5.0.0.jar

com.bea.core.weblogic.security.logger.ja_1.5.0.0.jar

========================================================================

Solution:

1.       If this domain is shared across multiple host, copy the missing modules directory jars from another host to the corrupted host.

 Or

 If this domains isn't shared across multiple hosts, you can copy jar files from another BPEL domain.

2.       Location of modules directory will be $ORACLE_HOME/modules.

3.       Make sure you have all required files and with the same size.

4.       Once done, restart admin server and it should come up fine.
