Cause and Effect: November 2008

I found the solution to my connection problem! One little change to my code ( Literally adding an s on the end of Pop3) has allowed me to connect to the mail server and testing has found the spam in my dummy emails!

from
try
{
Properties props = System.getProperties();
Session session = Session.getDefaultInstance(props, null);
store = session.getStore("pop3");
store.connect(popServer, popUser, popPassword);
folder = store.getDefaultFolder();

to

try
{
Properties props = System.getProperties();
Session session = Session.getDefaultInstance(props, null);
store = session.getStore("pop3s");
store.connect(popServer, popUser, popPassword);
folder = store.getDefaultFolder();

I am so happy :) this has been bugging me for days.

Java coding is definitely more complicated than I first thought.

I have "borrowed" the source code for a mail application with the intention of modifying it to interact with my flash GUI and i have managed to get the mail app to work... to a degree. unfortunately i have come acropper with the code because although it appears to work there are some connection issues between my computer and the mail server.

here is my mailreader

and here is what happens when i run it:

annoying to say the least!

Another issue i can't fathom to work around is jdeveloper does not work on my vista laptop! Upon which flash is installed and any hope of me combining the two parts of the organism. :(
