2 questions abt applets!!!!

hi folks!
im developing a web based chat server. im using applets and swing components. i have 2 questions that are irritating me.
1) for swing components to apply i have to install java plugin but that plugin will be installed only on my machine, how to make it available on to client machine and make applets visible as applet developed using swings will be downloaded on client machine??
2)how to notify arrival of message. any way to blink the frame?
hope u guys will remove this confusion. see ya

You have to have code on your applet that will ask the client to download the java plugin when they access your page. This has to be done only once.
I am not sure I understand your second question.

thanx for ur reply Bosun.
by second question wat i mean is when clients r chattin with each other. they should be some way by which client can know that a message has arrived like on msn the window of the chatter u r chattin to blinks n a sound is created. can i do the same in java??
i couldn get ur answer to the 2nd question

.
hope u clarify the confusion.
