When running Live API Creator you may notice the following entries logged:
WARNING: No encryption keys found, this is almost certainly BAD in production
Make sure that the encryption key(s) is present in server.xml AND in context.xml.
This error is by design, it is indicating that you are not using an encryption key to encrypt and decrypt the database password and occurs for all application servers.
The below article gives you an idea of why encryption key is needed and how you can configure it. The article talk about how its done for Tomcat or Jetty package, but it should be very similar for JBOSS as well.
Refer to the Live API Creator documentation section titled 'Manage Encryption Keys' for further details on setting this up.
