lock desktop using java code

[meghana]

hello

we are developing one application for lab.We have to lock our desktop. Whenever user put his id & submit it, if he is valid user then only desktop will be unlock. If he enter wrong ID more than 3 times then pc will be restart.

Please help us to solve this problem.

Thanks in advance.

Every modern operating system already has this feature, and if it's not implemented at the OS level, it will be trivially simple to defeat. Why do you want to attempt this in Java?

Hi

Actullly the function of application is like when PC starts desktop will be locked and my appllication is on desktop. NO other function will be used. When enter valid id the desktop will be unlock otherwise it's Log OFF. We already search the run time DDL for Log Off & shut down function Which used in JAVA.

for example:Runtime.getRuntime().exec("rundll32 url.dll,FileProtocolHandler " + "logoff.exe");

we want similar type for lock function.

sir

We want this application on client server. Our progrm is basically on the server, We have to run login page on many clients. So for that we want to lock the desktop of clients.
