I am trying to run a program on the command line that uses the JavaMail API. This program also reads in a message from a text file. However, I'm getting this error:
Error: A JNI error has occurred, please check your installation and try again

Originally I used java -cp /path/to/mail.jar mailTest < message.txt
I configured the classpath for the jar successfully (as far as I know). Can anyone give me some pointers? :/
