add javax.comm API on a mac
(2 answers)
Closed 6 years ago.
In that I connect hardware through USB. I need to write a program in Java to detect the port or pop up GUI page. So I need to communicate with ports. I am looking for javax.comm to download and attach to the eclipse. problem is I have a Mac and not getting link to download java.comm.
Oracle's page about javax.comm mentions RS-232 and IEEE-1284, but nothing is said about a support for USB. This question says:
It seems that Java comm API is dead now.
The good news are that there is an API especially for USB: JSR-80. An implementation of it is usb4java.

I wonder is possible to make a bot writen in JAVA, which will open some program(program is under windows), click on the button in this program and type some data, check status of this program(login or logout, this is client for online game).
Which JAVA tools I need ? I think that java robot lib is not enough for this.
Thanks in advance.
You cannot do this using JAVA.
JAVA is a language which is loosely coupled with operating systems, so it can only receive mouse/key messages from underlying OS. Among all the tasks you mentioned , it can only start the program by using Runtime.execute.
If you want to implement a software like this ,you should use Visual Studio and use Microsoft technologies.

How Do I Eject a Volume in Java?
(2 answers)
Closed 3 years ago.
I know that questions like this have been asked before, but I couldn't find any more recent ones and I have a twist to my question.
I've developed an application in Java that is designed to run on removable media, and work on both Windows and Mac. I would like to add a button to safely remove/eject the device, if it is supported (i.e a USB drive). Is there a command line for each operating system that would allow me to do this?
I know that it can be done by an application running on the device to be ejected, because I've seen one that does it, but obviously I understand there are certain limitations to Java.
Thanks in advance
This is something that you will have to do by invoking an auxiliary application. These applications are not platform independent as you wish. So, to do that, find out which OS you are on by using System.getProperty("os.name") and invoke the appropriate command for the detected OS. Invoking applications is done with Runtime.getRuntime().exec(). Search for the commands you need for each OS.

How to determine if a screensaver is running in Java?
is there any way you can find out if the screensaver is active with java? I've searched the web but the only things I found was very complicated native code... My program is made for windows only.
Java cannot handle system tasks directly.
You should use JNI (Java Native Interface) or JNA (Java Native Access) to do it.
I haven't tried this code, but they claim to answer your question with JNA as Ammar suggested: Screen Saver State.
