If an error occurs during request parsing, a
HandlerParsingException occurs. This exception includes error information that is returned to the client. If you need to retrieve the error information, you need to call
HandlerParsingException.getErrorData(). If an error occurs during the generation of a license because of DRM policy requirements that have not been satisfied, a
PolicyEvaluationException occurs. This exception also includes
ErrorData to be returned to the client.
See the API documentation for
LicenseRequestMessage.generateLicense() for details on how DRM policies are evaluated during license generation.
