whatever happened to reading the documentation and some tutorials?
Every question here is answered in full in the Tomcat documentation and examples.
If you can't understand those there's no way you're going to understand having it explained by people here.
And if you can't be bothered to read those and so help yourself why should we bother to help you?
As people are clearly allowed to attack me but I'm not allowed to defend myself, I no longer post to this site.
