System programing using Java

What java class library that i can use for system programing?

Do you mean device drivers and the likes? Java isn't the language for that. You can always interface Java with C and there's also the Micro Edition of Java. It depends on your situation if Java is useful.

How to read system eventlog using java program in windows?

How to read system eventlog using java program in windows?
is there any java class available to do this ? or any one having sample code for this?
Your friend Zoe

Hi,
There is no java class for reading event log in windows, so we can do one thing we can use windows system 32 VBS script to read the system log .
The output of this command can be read using java program....
we can use java exec for executing this system32 vbs script.
use the below program and pass the command "eventquery"
plz refer cscript,wscript
import java.io.*;
public class CmdExec {
public static void main(String argv[]) {
try {
String line;
Process p = Runtime.getRuntime().exec("Command");
BufferedReader input =
new BufferedReader
(new InputStreamReader(p.getInputStream()));
while ((line = input.readLine()) != null) {
System.out.println(line);
input.close();
catch (Exception err) {
err.printStackTrace();
This sample program will list all the system log information....

JNI. (No.)

New "Windows Programming Using Java" Website

Our newly created "Windows Programming Using Java" website (http://fivedots.coe.psu.ac.th/~ad/winJava/) is for programmers who want to extend Java's capabilities on Windows XP and/or Vista, but aren't sure where to start. One of the drawbacks of Java's portability is that many Java programmers have a rather sketchy knowledge of Windows-specific programming.
We plan to explain how Java applications can utilize Windows application software, OS features, and hardware beyond the reach of Java's standard libraries. A variety of Java/Windows programming techniques will be explained, including:
* Java's employment of the Win32 API via C, JNI, and J/Invoke.
* Java's utilization of Window's Command Line Interface (CLI) and batch files, accessed through Java's Runtime, ProcessBuilder, and Process classes.
* Java and Windows object-based scripting, centered around the use of VBScript, Windows Script Host (WSH), and Windows Management Instrumentation (WMI).
* Java interoperability with COM, including hosting of ActiveX controls in Swing containers using jacoZoom.
This website is a work in progress, with four chapters available for download at the moment. We'll be adding more regularly, and would love feedback on what we're doing.
Thanks,
Gayathri Singh and Andrew Davison

Hi, I am looking the similar kind of requirement that you had done.. Do you have any more details on the code that is working for you . All i need is if the user logs in successfully in windows, the the app should be accessible. Please let me know if you have the code with you on this problem.
Thanks in advance
"what i meant is the we b applications running in my system, when i access the application iam able to to login automatically with windows authentication and now in case of other users following process happened:"

Kernel programming using Java

I'm currently doing a research in computer security and would like to develop a system which can deal directly to linux kernel in order to enhance the security. During my research I found that Java is a type-safe language which is more secure if I develop my system compare to C language which is lack of type-safe. So I decided to use Java to develop my security system which will enhance resources management in Linux. My question is, does anyone know whether Java could be used in kernel programming or not? Where could I get some sort of references related to my work especially tutorial about kernel programming using Java. I would appreciate if anyone of you could help me in this matter. TQ

I'm currently doing a research in computer security ...You might want to do a bit more research into the languages.
What you are discussing has nothing to do with security.
If you are writing kernel services then java is probably ill suited because the normal implementations use garbage collection which is not under your control. This makes it hard (if not impossible) to control timing.
If your sole desire is type safety then C++ provides better type safety and provides more control over types as well.

Can i change system time using java

hi guys can i change system time using java iam doing one app in that i have to change the system time (my os is windowsXP) please tell me how to change the time

What does this have to do with Swing?
Well, there is no Java API that I'm aware of.
However you can execute any Windows command by using the Runtime class. So you should be able to invoke the Time command.
Search the Java Programming forum. There are plenty of examples on using the Runtime.exec(...) command.

System programming in Java

Actully I'm working in Automatic distinction between the system progam & application programs. Is there any samples/source code of the system programs available in java???is it possible to distiguish between the system program & Application program by seeing the code??
Cheers!!!

Just curious what is it system programming in java? Can't recall any example...

Stoping System Clock using Java code.

Is it possible to do so if yes then some code idea for
Stoping System Clock using Java code.
[email protected]

The system clock is controlled from the BIOS, and as such, I don't think even windoze can stop it, though it can be continually reset. I don't believe that Java provides a sufficiently low level of control to set the system clock, although you could use a native method to accomplish the task.
Why would you want to do such a thing?

System configuration using java

Hi friends
Can I get System configuration using java code.
If yes plz suggest how.
thanks in advance.. Anjana

some bits and pieces are available see the details in
System.getProperties():
Properties sysProps = System.getProperties();
meration en       = sysProps.keys();
while ( en.hasMoreElements() )
//add the key=value pairs
Object keyObj    = en.nextElement();
String key       = ( String ) keyObj;
Object valueObj = sysProps.getProperty( key );
System.out.println( key + " : " +
+ valueObj.toString());
de]
just an idea??YES, and also you can do
System.getenv();but they also don't give all the info the OP was/is looking for.

Embedded system programming in java

Systems programming in Java

Is it possible to write system programs in java language? where can i find examples?

like writing device drivers or interacting with hardware i.e. ports input/output just like in 'C'..
If it is possible to write device drivers in java.....then we need not to write drivers for Windows, Solaris and linux separately. Just write device driver once and run it anywhere.. i don't know it is feasible or not.

Mail Program using Java as...

HI!
Is this possible in java...
to make Mail Program using Java as frontend & use Outlook Express database as backend
PLease Help...
Bunty India

Hi Gandalf,
I picked up your code and ran it, couple of things, firstly windows and Unix line terminations are different so in your method doCommand use "\r\n" not just \n, this will give a full <CRLF>
On you initial HELO you want to use your computer's id as part of the command so use this line:
sender_domain = InetAddress.getLocalHost().getHostName();
String s1 = new String("HELO " + sender_domain);
s1.trim();
response = doCommand(s1);
Cheers
Dom
