i am writing a web based mail client in jsp. i have tomcat3.2 running
on a freebsd machine.
i am using java mail package and have managed to connect to the pop
server and get a list of the unread mail. but when i try to view mail
that is just plain text something strange happens.
the message is just printed out without some return carriages.
example:
Hi, one more question:) THe PrintWriter class has both write and print
method. THe one i saw in your notes is the print method. What's the
difference between the two methods? thanks, Ge Sun >From: Peter Choe

but when i view this in a java application and use System.out.println()
to print it is normal. when i looked at the code in the works
directory, i noticed that the code say out.write() where out is an
object of JasperWriter. how can i print this message with the correct
line carriages?
