I am thinking of developing a network application for my PhD, and it
involves (among other stuff) my own implementation of the TCP/IP
protocols. So, at the state the Java 1.5 version is, I need the use of
JNI for the RAW sockets. (Although the use of Java is not a MUST, I am

Where is the Java Plugin for 1.5.0?
I've just updated one of my applets to use Java 1.5.0 constructs. It works
fine in the AppletViewer so I decided to put it into a web page and check it
out; I started bringing the HTML for the page up to the 1.5.0 level and was

I'm pretty sure you can do this but for my final project I'm gonna make
an applet thats like a quiz thing and I want the persons final results

upgrade to double the speed and size of its SCSI drives.
It has two more upgrades to go, the first is doubling RAM to 4 GIG

I have read that the main purpose of JavaBeans is to build reusable
