Why would you want to write a virus in java?

I'd say sure, depending on what you define as a virus. You can write trojans in any language. For example, I can write a complicated program that deletes every file on the harddrive in java anytime some clicks 'save'. I'd barely call such a program a virus though given its limited mobility.

As far as self-replicating, outlook-infilitrating viruses that install themselves when you open an e-mail for example, I don't know of any in java since they require a JVM to be present.

What you are asking for can be done, under certain constraints. But I'm not inclined to explain how to anyone who asks. When I teached advanced topics in Java programming -- rare these days, but it does happen -- I walk through this process.

Needless to say, my entrance requirement for such knowledge is a responsible programmer whose name I know and whose face I can see.

Thanks ME:
I like your very responsible approach!!!

In the early days of Java, MANY people took a very hard look at the security precautions and Sun was very responsive at fixing the holes that turned up. These days the holes we hear about through Secunia.com are pretty subtle.
