Where do you define the charset a mail is sent with if you are using a Spring JavaMailSenderImpl?
We are using the Spring JavaMailSenderImpl with a mail session we get from the Websphere Application Server 6.1. Strangely, the charsets used in sending the emails are different on different systems using the same code. I am looking for a way to override the default.
UPDATE: Changing system properties is not allowed for us. So I am looking for a way to specify the used charset in the code or in the deployment descriptors, webshpere meail session settings or whatever.
