How to Use native keyword in java programming

Hi ,
I am using JDK 1.6.0_11 , and i was trying to create a java program using "native" keyword ,
i got the sample code for the same from the site : - http://www.javaworld.com/javaworld/javatips/jw-javatip23.html
But when i type this command " C:\javah -stubs Happy " following error occurs
" Error: JNI does not require stubs, please refer to the JNI documentation. "
then typed " c:\javah -jni Happy" without any error .
After that i wrote a HappyImpl.c as mentioned in the above tutorial
#include <StubPreamble.h> /* Standard native method stuff. */
#include "Happy.h" /* Generated earlier. */
#include &ltstdio.h> /* Standard C IO stuff. */
void Happy_printText (struct HHappy *this)
puts ("Happy New Year!!!");
then it is not compling and error is
"unable to open included file StubPreamble.h file
unable to open included file Happy.h file "
Please help me . i want to use native method , i did exactly the same in tutorial at above link.
Thanks & Regards
Mannat

you do need to know how to use your C compiler... It quite clearly can't find those files which indicates that you didn't tell it where to find them.

Help--How can I open only one java program at one time?

How can I open only one java program(same program) in Windows at one time?

In Java 1.5, you can use the JVM's own monitoring APIs to examine what other JVMs are running on the system, and what applications they're running.
It's general and powerful, but complex. The socket/file/whatever approach is cleaner, and probably more suited to your usage.
Don't bother trying to use the Windows task manager for this sort of thing. You have to write messy native code, and it isn't reliable after all that anyway.

There isn't any core Java API for this. Use JNI or call an external process with Runtime.exec().

How to use C-Structure in java applets

hi alls,
I want to use a struct model (struct in C++) in java applets. i know class is used in java applications. but, how can i convert in java applets?
class renk
int r;
int gr;
int b;
import java.awt.Graphics;
import java.awt.Color;
import java.awt.Event;
import java.applet.Applet;
public class benek extends Applet

clr[count].b = b1;
x[count]=xyer;
y[count]=yyer;
count++;
repaint();
public void paint(Graphics g)
it gives error message... how can � use struct model in java applets???
if you help me i will be greatfull....

� use import but it doesn't work.
i add: import renk; or import class renk;
how will � add import I assumed based on your initial post that the renk and benek classes were in the same file. Apparently you're saying they are not. So for another thing, make your renk class "public class renk", and add the "public" keyword to the 3 members of that class. Then if your code still doesn't see the "renk" class, it would just be that you don't have the directory that contains the compiled "renk.class" in your classpath.

How to use " toFront() " method in java application and in which package or class having this toFront() method.if anybody know pl. send example.

The API documentation has a link at the top of every page that says "Index". If you follow that and look for toFront(), you will find it exists in java.awt.Window and javax.swing.JInternalFrame.
To use it in a Java application, create an object x of either of those two classes and write "x.toFront();".

For some reason I cannot use characters like: " ^ ~ | " in java programs.
I can type them in a terminal and then paste them into the program, but cannot type them inside the java program - It's has been like that in every java application I have used. It only works when typing them in a applet running on a browser.
Im running Linux RH 7.2 with JDK1.4.0 (It works fine in windows 2000)
Hope somebody can help me.

Ehmm. What makes you believe that it isnt?
I can't make exclusiveOr operations and if(bubba || bubba2) something....And that is a problem / annoyance.
I can type every other characters but those �� works fine as well.

How to access system registry through java program

Friends
I have to access System registry of Windows 2000 by Java program. I don't know how to access the registry by using java code. Please help me. Else
I want to create a setup file for my application. before setup my application i have to check whether the system has JVM or not. If its not then i have to install JVM first and then my application. so i need to access system registry. please give me a solution for this.
Thanks in advance
Ramesh

I don't know how to access the registry
by using java code. You can't, without using a native interface (JNI type) library.
This is one, there are others, do a Google search:

How to run sscript shell with java program

Hi everybody,
i want to know how can i do to execute a script shelle (bash) with program java (if it s possible)
for example this script:
#!/bin/bash
echo "hello"
can i run it with java program or i have to make dome modifications .
thank you for your help in advance.

Well, if you want to be portable across platforms, you should write as much code in Java as possible and not rely on native scripts (I'm sure your script is more complex than this 'echo' example ;-) ).
Having said that, you can use the java.lang.Runtime class and in particular its various exec() methods.
Try something like this:
Process p;
try {
p = Runtime.getRuntime().exec("myscript.sh");
} catch (IOException ioe) {
}You can then "interact" with the spawned process with the Process object returned by the exec method.
Note you need to have the appropriate security rights.
For more details, look at the API documentation here:

How to pass native struct to java

Hey guys,
I've got a legacy C++ prog that outputs structs to a binary file & I've got a header file defining that struct.
I want to read the file and get the structs via java but I've never used any interface between the languages.
All I've managed to come up in my searches is "how to pass java objects to c", well how do I do the opposite?
Help appreciated

I hear you calling me :)
If this interests you I'll explain the problem from the beginning-
I already have a C prog which outputs a HUGE binary file (therefore text is probably not a good idea),
this file consists of a header followed by some number (defined in the header) of a certain struct (consisting of ~20 fields ints, longs, strings...)
Another C program exists that reads this file. I am currently building some sort of visual interpretation of the data using java.
As all C code is quite heavy duty [and works like it should :)], and a few other reasons, I do not want to change it.
That leaves me with an existing file containing binary data I need to read into the Java UI.
sztejkat > Why use native code?
I would have really wished I could do this entirely in Java, as for portability - it doesn't have much consideration, just in terms of "clean" programming.
As you said struct packing is something unpredictable, therefore I do not see a way of reading one without using C.
bschauwejava > I suggest you try to be less vague about the results you are getting.
Sorry :)
This is the structure: File (package) -> File.java, InsInfo.java (classes)
I'm using "javac File.java"
And I'm getting:
File.java:3: cannot resolve symbol
symbol : class InsInfo
location: package File
import File.InsInfo;
^
File.java:20: cannot resolve symbol
symbol : class InsInfo
location: class File.File
public native InsInfo readIns();
^
2 errors
(the arrows actually point to the first letter in the class name)
If I use "Object" instead of "InsInfo" javac compiles the .class without problems.
I'm using Jbuilder and inside it the import is OK. When I compile it with Jbuilder everything is OK.
I actually haven't thought of this until now, I'll try to use the .class Jbuilder produces to generate the header.
btw- Thanks for getting so involved!!
