Hardware identification using Java-application

Hi,
please help me! I would like to get some hardware-specific information using a Java-application? Is it possible?
Thanks everybody,
dzsitter

Probably not, in pure Java. Depends on what the "hardware" is that you had in mind.

How to ge a hardware id using java?

how to ge a hardware id using java? like cpu id??

Why do you want the CPU code ?
If you could read this using Java, it would fail most of the time, because a great many people are either not running Intel CPUs, or, like me, have the identification number 'feature' turned off.
You'd get along much better if you view the Virtual Machine as the hardware on which you are running. Thus the concept of a CPU, or the 'Operating System' doesn't exist. Not true, but it would save you a great deal of disappointment, and would make your code much more portable. Can your code run on a machine that interprets Java natively in the CPU, for example?

How to send attachments using java application and outlook

Last time I checked, SMS was a service between carriers and doing SMS yourself was really tricky. Some services existed to let you do it but as I recall they wanted non-trivial money.
However, most phone carriers provide an email-to-SMS bridge of some kind.
So the easiest thing is just to send an email.
That's sending from a non-phone to a phone. There's a J2ME library to send/receive SMS from/to a phone.
However, this is from memory, and a little out of date, so I could be entirely wrong. Hope it helps anyway.

Process Identification using java- GUID

How can I access a process identifier using java code?
in fact i am developing a Group communication application, in which multiple processes communicate each other, and this requires unique identification of each process. for example to determine the sender of a message, i need identifier of the process which has sent the message.
So please sugest me how can I use Process Identifier or Is there any alterative way, for example I have an idea to use some Globally unique identifier (GUID) for each Process involved, But I dont know actually how to implement that Gloabally Unique Identifier (GUID). Please help me to solve this issue.

Sounds like the socket is the identifier.

Closing cd tray using java application

sir,
i want to close the cd tray using java program.i opened it using a vbs file which can be called through Runtime.getRuntime().exec("WScript <filename.vbs> ");
But i want to know how can close this cd tray using java programming...
the vbs file cotains the code for opening as
CreateObject(\"Shell.Application\").NameSpace(17).ParseName(\"g\" & \":\\\").InvokeVerb(\"e&ject\")");
Now i want to close the cd tray using a vbscript or through any other method which can be implemented in java..plz help me...........

You can not do it directly, it would have to be via Runtime.exec, or JNI.
As to how to do it via VBScript, this would not be the best forum to ask on. I'm sure Google will tell you if you ask it nicely.

Do you actually mean you want to make sure that only one instance of a GIVEN Java program is running at one time? If so then search this forum becuse this question comes up frequently.

Hi Again Monty.
I may have given up too soon.
Click once on the downloaded TheGame.zip file to highlight it.
Press the Command⌘ + I keys, to Get Info.
Change Open With to Stuffit Expander.
Double-Click on TheGame.zip.
A folder titled TheGame will be created. Open that.
In there will be:
decks An Empty Folder
Game.jar
game.xml
images Folder This one has many sub entries.
preferences.properties
readme.txt
release_notes.txt
runme.bat
When I Get Info on Game.jar, Open With is set to Jar Launcher.
That's as far as I am going though. does that help any?

Want to shutdown solaris 10 using java application

Greetings all!
I have been unsuccessful at creating my application to shut down a Solaris 10 server with a java application. I am hoping someone might be able to point me in a good direction here.
I want to log on as a regular user and run a java application that monitors remote information (UPS battery voltage) and will gracefully shutdown the server if there is a problem. If I run my application as root all is well, except that I am running as root :)
I can write code to access the shell:
Process proc = Runtime.getRuntime().exec("ls");
BufferedReader Input = new BufferedReader(new InputStreamReader(proc.getInputStream()));
while ((s = Input.readLine()) != null) {out.println(s);}
But I can't do a "su"?
I've tried multiple examples out there of code that allows shell communication, and good examples of using Runtime.getRuntime()
I think the conclusion is that you can't issue a su command via java application.
I've also tried to telnet from a console to localhost and log in as root - no joy there either.
Would someone have information that might point me in the right direction to solve this problem? Even better, if there is a sample snippet to go along with any help.
Thank You very much!
Ray

Wow,
Thank you for the very detailed response! I read the referenced web page last night, I'll read it again today too. RBAC sounds like a pretty complicated administrative tool. Coming from the Win32 domain, most of this security stuff is sadly uncharted territory for me (except for my mac).
Let me see if I understand your method:
Create a role, javarole, this role needs Primary Administrator priviliges (in order to invoke "shutdown -y -i5 -g0") only available to root
Create a powerdown profile, essentially a script:
this line creates the file:
# echo "powerdown:::profile to powerdown server:help=powerdown.html" >> /etc/security/prof_attr
I think this is the actual added script: (instead of the shutdown command just use init 5)
# chmod 755 /usr/sbin/powerdown
# cat > /usr/sbin/powerdown <<EOF
#!/bin/sh
/usr/sbin/init 5
EOF
This line is a bit confusing to me, is it also part of the script?
# echo "powerdown:suser:cmd:::/usr/sbin/powerdown:uid=0" >> /etc/security/exec_attr
I see the uid=0 (root)
It seems obvious to me that I log in a root to create this script, which is the reason it has permission to shutdown...right?
Also, I tried the su command using runTime.exec("su poweroff"); // a user I created to try poweroff scripts
It seems that su is generally not available, I will create the role and try to telnet to it.
What about creating a generic user script that includes the javarole name and password, and then run the script "/usr/sbin/powerdown"
Yes, it leaves a role password exposed, however it is a very limited role, that is not accessible by a user login, but the turn off script is available to every user?
Regards,
Ray

X high CPU when using Java applications

Only recently, my Freemind program has become extremely sluggish and unresponsive (big lag) when moving my mind map around. Freemind is made with Java. If I move the mind map around, the X process shoots to 20% CPU, doesn't seem a lot but something between X and Java programs are really bringing their performance down.
I can barely use Freemind now. Freeplane is also affected.
I noticed if I keep the Freemind window really small, it's responsive. If I maximise it, everything slows down within the application. Adding new notes, or move the map around, shoots X to a high CPU and there is a 5+ second lag in anything I do in the app.
Is there anything I can do to improve performance? It's only started recently, everything is up-to-date.

Hi
Try to use -Xloggc parameter with the jvm in order to see if problem comes on garbage colector. May be the mem usage is little and the gc thread is in active state. Try, also modify the mem usage with -Xms and -Xmx parameters and see the gc efects.
You can use the -Xprof to output cpu profiling data.
Also, find if there is a bug on servlet container / hard /SO you are using.
Hope this helps
