This is a simple symptom-cause-solution blog entry only. I hope these blogs will help fellow administrators. Symptom In wls_utc, when trying to test a webservice using SSL, the following error message is received: javax.net.ssl.SSLKeyException: FATAL Alert:BAD_CERTIFICATE - A corrupt or unuseable certificate was received. If SSL debugging is enabled, the following error also appears in the logs: ExecuteThread: '4' for queue: 'weblogic.kernel.Default (self-tuning)' < 1254822672320>> verification failed because RSA key public exponent [3] is too small Cause The certificate encryption is of a weaker strength than expected by newer versions of Java. Solution Add the flag "-Dweblogic.security.SSL.allowSmallRSAExponent=true" to the server startup parameters. References None.
