I'm not trying to write anything, I'm trying to figure out Java's relationship to an OS. I know the JNI has more functionality, but I thought it also acted as the connection to the OS. What mechanisms allow java to communicate with the native OS? As I said, many things couldn't be done, to my knowledge, without some communication with the OS.

The JVM (Java Virtual Machine) is written in native code, customized for the OS+machine architecture it runs on.
It is the interpreter of Java bytecode and decides how that code should be translated to native code for its platform.
Sun publishes the specs on the JVM so that anybody can write their own.

I had debug code below, it step thru the codes without any error and without any popup window.
The lines of code describe as follow:
Protected Sub ButtonSave_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles ButtonSave.Click
----before window.open, I have did some filtering ---
Dim sScriptWindowOpen As String = "<script>window.open('message.htm',null,'left=400, top=100, height=250, width= 250, status=no, resizable= no, scrollbars= no, toolbar= no, location = no, menubar = no');</script>"
ClientScript.RegisterStartupScript(Me.GetType(), "anything", sScriptWindowOpen)
End sub

Have you tried RegisterClientScriptBlock instead of RegisterStartupScript?
ClientScript.RegisterClientScriptBlock(Me.GetType(), "anything", sScriptWindowOpen)

you have to set the multiple attribute for select.
var myListBox = document.getElementById('your-listbox-id');
myListBox.multiple = "multiple";

Hi there,
could the package javax.sip helps in an application that is supposed to send register and invite messages (sip message) to a specific server  , the server is an asterisk PBX, instead of using the java asterisk,
in other words: part of the application is supposed to talk to the asterisk , and I want to do it via the javax.sip, as the application already contains sip functionalities,
any help please, tutorials, links that teach about sip programming using javax.sip code samples, main classes that I might use
thanks in advance
There is always something to learn

Hi everyone!
I'm working on a project and i need to do what follows:
i have an array of strings,example:
house3
house2
green23
green.5
H6
H01
G19
G78
..and so on.
I have to extract only the recurrent strings: house,green,H,G.
Any idea about it? (the language is java but doesn't matter, i just need the idea!)
Thanks in advance,
Enrico.

I recommend Assembly. You could go with machine code if you needed more control, but I find it takes a lot of time lining up the 1s and 0s properly.
Do you know what a loop is?

Hi there,
I use implement some dll using java-native-interface (JNI) and try to call the JNI function from a java application. In java run-time environment (JRE) 1.6, the program works fine; while in JRE 1.5, the program will crash and return EXCEPTION_STACK_OVERFLOW in the eclipse debug console window.
Now that, the customer is using JRE 1.5 and not willing to update to JRE 1.6. What can I do to make it work in JRE 1.5?
Thanks a lot!

The best answer we can give is fix the stack overflow problem.

I have figured out how to fix this.
Yes, it is a stack overflow issue. But the problem is not in my code. It is because JRE 1.5 limit the default stack size to a small amount.
Java pre-allocate stack for native library. In JRE1.5, the default stack size is 128k. To make an application run with bigger call stacks, one needs to use the native stack option (-ss) when executing a class or jar file.
I make my application work in JRE1.5 by using the following command:
java -ss1024k myclass

Hi! I have some questions concerning mobile phones. When I build a simple project like "Hello World" and upload it on a mobile phone, will it display "Hello World" when I run it? The other question is how can I make the mobile phone's camera flash light (the phone is Nokia N95) and become a torch? (in Google all that came up when I searched for the torch was how to make the screen white)
Still learning...

You can do all of these things and more with Java, but the secret is you can only do them after you learn to program a bit!
But, yes, all of them are possible. I didn't see a question that doesn't involve coding applications for you in there though..

You might want to Google on "flashlight" instead. Good luck.
