Question
How to detect (hook) the Keyboard and Mouse idle time in JAVA running Windows or Linux?
Hello experts!
I actually have an application coded in Delphi that helps me to track the hours my programmers spend in a task. For that I detect the idle time elapsed (how long they don't use the keyboard and/or mouse) and based on that info I summarize only the real hours... no matter what application they are using (it is in my todo's)
Well my problem is that for example I've decided to work with Linux, and also I have many programers working in linux and mac; so I want to create a program in JAVA (because is more crossplatform) that can work in all platforms (catching the idle keyboard and mouse time ).
I have executed my actual application .exe using wine.. but it doesn't work, just catch the keboard and mouse actions in the aplication but not in all the client host.
Thanks
JHL

Java (or actually the JRE library system) basically is an abstraction of things common to most operating systems. This is why Swing is such a hard thing to get right; there is quite a bit of difference between the systems, so there is a lot of things Swing has to do itself. Low level stuff like mouse movements within the OS won't be part of it. So you will have to have a bridge to the OS and go native. JNA as objects mentions might be something for you.
I really wish I had. Maybe it's better to ask the question as well in a C++ zone as well. That language has got the most low level libraries, maybe there is a library that is the same for all platforms. Otherwise you may have to write a small C++ JNI piece of code for the three platforms using OS calls. A quick Google search would suggest such a thing.
JHL, please notice that you've not posted a real answer to the solution. In that case it is better to ask an admin to close the question. It now seems that you've answered your own question, while the question has not been resolved (and won't be until somewhere in the very far future decides to create platform agnostic Java API's for this functionality).

Now that's a coincidence since someone was asking me a few days ago how he could produce cross-platform keyboard and mouse movements simulating his doing some work.
Seriously though, why would you think Wine would help? That will at most only catch events in the Windows 'vm'. You need to implement keyboard and mouse hooks at the native level for each OS
