java mail api : exception thrown saying java.lang.SecurityException: Access to default session denied

Question

when im trying to send a mail using java mail api in my web application , I\'m getting this exception.

java.lang.SecurityException: Access to default session denied

Answer 1

I've got the same error, when I launch 2 tests in Webdriver. In secound test i've got "java.lang.SecurityException: Access to default session denied".

When I used method Session.getInstance instead Session.getDefaultInstance in every test, errors disappeared.

Answer 2

This error text is associated with a call to Session.getDefaultInstance(props, authenticator) where the default instance already has a different authenticator set.

It should work better if you call Session.getInstance(props, authenticator) instead of Session.getDefaultInstance(props, authenticator) in your code.
