So after a bit of digging [1,2] I found that this is achieved by
adding the following parameters to the mysql jdbc url in the resource


Note that  [2] has a couple of errors.
A) it specifies clientCertificateKeyStore[Url|Password] in lieu of
trustStore system property, that should be
B) it specifies specifies the urls in the form
file:path_to_truststore_file, that is also incorrect it should be
file://path_to_truststore_file (which will give a triple slash if an
absolute path is used)


Hope this helps someone else that happens to read the archives.
