the package javax.mail is not accessible [closed]

screendump and screendump2 and screendump3

I just can't figure it out and I'm begging for insight. Im writing an email app and Im beginning with examples Ive found lying around.

My code has the directive "import "javax.mail.*";

This generates the error "The package "javax.mail is not accessible";

Im using Eclipse and Ive added a number of JAR fies into the modulepath, but Eclipse is stubborn in this regard.
Any Ideas? I'm seeing rafts of similar requests but none of them seem to help me..
