That version is no longer supported by the "vendor" (Apache). You should tell your hosting company that you want a supported version if they are going to charge you for it :) May I know what version should I go for ? > But, the re-start of server is not in my control. > > I would like to know if this is the normal environment in a web > hosting company ?

If it's "their" instance and not yours, then you probably won't see that. What kind of access do you have for the server? If you have shell access, you can probably get the logs. Using System.out.println is not a great idea as it's pretty inflexible. It's better to use a "proper" logging system where you can specify the log file name, etc. I do have access to the Catalina log. The technical support guy just told me that they have put in the logging jar for me in their Tomcat server! > What they told me is "Only if there is system level operation.

If you are using container-managed authentication (which is what Tomcat Realms provide), then you have to trust the hosting provider. There is no way to prevent the hosting provider from seeing any secrets you have in that configuration. I am now mulling if I should use JWT. In this case, I can skip the Realm configuration in tomcat right ? - -chris -----BEGIN PGP SIGNATURE----- Comment: Using GnuPG with Thunderbird - https://www.enigmail.net/ iQIzBAEBCAAdFiEEMmKgYcQvxMe7tcJcHPApP6U8pFgFAlzZ450ACgkQHPApP6U8 pFi/EhAAhVS64ib8GzAl6PNLISm/rYeZ765eFg9eqRwCpPnss6ZuW/kD9moznKhN cj17X84itq3VihkRV+S/xnVM8TZ7OG71dwyhgrQUDcixuU9F37GVF16K5/gqHrF1 cu5QrMWw9oPFIEUWEi3jaUJF233Jm9y5IgHCyyieAbcDiCm5Gl9NVd1opQHWBkKZ YqH0xGVGxADAf9QiFnkmX5ZEq2REaGr6sV5b2oKgQCKv2iEoCvWxFYuyqG1iIbz1 wgbHqOy/adSdqvN704HcMaLTB7sfWBppp5RQyzN4Pz0Dx45845JRTWEdZpZ+YTop 1Xa1NhkYd/MqV+VZoi0Ivd+pvva5cGKR4zPFKXW9KRFw3Gl+cLoQPlyXxN8k3yZv PDCDlRqAFoAZakJ6BC4HHarAPJzRWGPON1UWhtXR7VdLXCRhcLcMMZg1UX3n9HJ+ ycw3haS99/0GPs1kMLNZ2Jk0QGf7v/lrU84PDQG8l27hJ8p4lJ4TqwxqMR0Nx9Uv iTpGodreOFJ+FXDegxYZNyrnOyOAuVl6Qi3iTz5bphuUa0FLrcX8pSJIt5PtgEFj qr71idqFeagCbbDJw/CtqchhEsTLyvfTFoNcTD2C5xuoG/Bo113/SKi4ffWTagxz y+nNPdRaKZ+dR+JotM37+7BYKxtNGnabaNT4nMUT04pHOdCmPSw= =kD0S -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
