Symptoms: When starting the Weblogic it presents error such as this:

Error message: JPS-01055: Could not create credential store instance. Reason oracle.security.jps.service.policystore.PolicyStoreException: javax.persistence.PersistenceException: java.lang.ClassCastException: oracle.jdbc.xa.client.OracleXADataSource cannot be cast to java.sql.Driver (...)

Cause: This message error comes from many reasons, but the one given in this example is related to the hostname  on the configuration files.

Solution:
Find the file jps-config.xml that resides on $WEBLOGIC_DOMAIN_HOME/domain_name/config/fmwconfig and make sure the hostname is correct.
Below is the piece of code with hostname reference. Fix it and startup again.
