Question: My applets are big and it takes much time to download (on browser) when a network is slow.
Is there any way to decrease the start up time?

Answer: The good solution is to make a small core .jar file that contains part applet that is necessary to start it up (initial GUI elements) and rest of classes can be loaded later when applet is already running. Nobody use 100 % of functionality directly and will give an impression that everything is ready...
This solution is good due to another reason also. If browser lost connection during loading of one big .jar file you need to start everything from scratch. If it happens with our solution browser will cash part of classes and it will save time for reloading!

Usually you don’t need all the functionality of the applet at once, so the applet can operate before all of its possible functionality is downloaded. And .jar and .class files does get cached by most browsers.

Question: I see this error message:

java.net.SocketException:
Connection reset by peer: socket write error even when I use Tomcat as a localhost server.

Answer: This behavior results from HTTP protocol. Each new page request results in a new TCP connection. When a user press STOP or RELOAD button or goes to another page the browser resets the old connection resulting this exception on server side.

Do not worry about, just properly handle it!
