How to make a java-program to a exe file runing on windows?

i kown that there were many topics on this problem.
i want to kown how many kinds method to do this i can use now!
i met a java-program can run on windows,but i don't find ant *.class
files and *.jar files.it's extended file type is ".ese".
thanks very much

There are commercial products that allow you to do this (e.g. InstallAnywhere from http://www.zerog.com).
One issue is that you have to decide whether you want to bundle a JRE with your program or not. If you do (and you should, in these days of XP shipping without any VM of its own), your program will be a minimum of about 9MB + whatever you actually add as part of your program :-).
In any case, this is not a trivial undertaking.

How to make a Java program that recognises a function of two variables...

How to make a Java program that recognises a function of two variables to assign values to that?
First I will give an example and then do the question.
Ex1.
We have any function, eg.y = x ^ 2 + 1 (read 'y' equals 'x' high to the square), a function of the second degree.
To build the graph of this function attach values to 'x' to find the values of 'y'
And thus mount the pair ordered (x, y) which represents a point on the Cartesian plane.
Assigning values to 'x' 'we can build up a table that gives us the pairs ordered:
We can use any numbers, but arfer interval [-3.3]
X | y = x ^ 2 + 1
-3 | Y = (-3) ^ 2 +1 = 10
-2 | Y = (-2) ^ 2 +1 = 5
-1 | Y = (-1) ^ 2 +1 = 2
0 | y = (0) ^ 2 +1 = 1
1 | y = (1) ^ 2 +1 = 2
2 | y = (2) ^ 2 +1 = 5
3 | y = (3) ^ 2 +1 = 10
We then ordered the pairs:
(-3.10), (-2.5); (-1.2), (0,1), (1,2), (2,5), (3,10)
Tabem that can be represented by a table:
X | y
-3 | Y = 10
-2 | Y = 5
-1 | Y = 2
0 | y = 1
1 | y = 2
2 | y = 5
3 | y = 10
Now I begin to explain my doubts.
See this program:
Ex2
* To change this template, choose Tools | Templates
* And open the template in the editor.
Encontrando_o_valor_de_y package;
* @ Author des Soldat Gottes
Import javax.swing.JOptionPane;
Public class (Main
* @ Param args the command line arguments
Public static void main (String [] args) (
Int x, y;
String x1;
X1 = JOptionPane.showInputDialog ( "We have the function y = x + 1 \ n" +
"Assign a value for 'x',"); / / receives a value for the function y = x + 1
X = Integer.parseInt (x1); / / tranforma String in int
Y = x + 1; / / receives the value of 'x' and calculates' y '
JOptionPane.showMessageDialog (null, "The value of 'y' is: \ t \ t" + y);
/ / Displays the value of 'y'
System.exit (0);
We see that the program receives above a value for 'x' and replaces the function contained in the program, y = x + 1, and so is the value of the variable 'y'.
In: x1 = JOptionPane.showInputDialog ( "We have the function y = x + 1 \ n" +
"Assign a value for 'x',");
The entry is a number and that number is assigned aa ja existing function in the (y = x + 1).
The question is: would it be possible to come to a function?
Ex: the program ask: DIGITE THE FUNCTION?
The USUARIO DIGITARIA A FUNCTION ANY, TYPE: y = x ^ 2 +1
The program would recognize the function and give numerical values to that function as Ex1, at the beginning of this text.
And then to find the values of the x and y launch a table.
It would be possible that?
By invez of entering with a number so that the program sustitua a function ja existing as Ex2, seen above, entering with a function quaquer (type: y = x ^ 2 +1) for the program atribuisse values to that function and then create a table of values as Ex1.
I hope it has been easier to understand my doubts now.
Thank you for your attention!
God bless!

But as it applied to a program?
How to create a program that recognizes that the entry coefficients?Are you asking about how to parse out the coefficients from the string "3x^4 + 4x^3 - 8x^2 + 5x^1 + 2x^0"? If you define the format to strictly follow that example, this should get you started:
Strip out the spaces
Split the String on "x^"
That should give you [3, 4+4, 3-8, 2+5, 1+2, 0]
Split each resulting String on "+ | -", preserving the operator as a token so you can apply the correct sign to the coeff.
That should leave you with [3, 4, +, 4, 3, -, 8, 2, +, 5, 1, +, 2, 0]. Every other number is a coeff, the rest are the degrees.
You can strip out the +, since those coeffs are already positive, and strip out the - after negating the following number. This is all assuming that you have to write this yourself. There is no doubt already a library or 5 out there that does this for you.

GOT IT !!!
I had to change the name of the method in .h file generated by javah command. On doing
javac -d ../../classes HelloWorld.java
go to the ../../classes directory (where you have the class file) and do
javah HelloWorld
I got a HelloWorld.h file in which I had
JNIEXPORT void JNICALL Java_HelloWorld_display(JNIEnv *, jobject);
I added the package name too:
JNIEXPORT void JNICALL Java_GUI_HelloWorld_display(JNIEnv *, jobject);
The HelloWorldImp.c file should have the same name (ie with package) and be in the same directory(ie ../../classes)
compile and build the shared library to get "libhello.so" file
gcc -c -fPIC -I/usr/lib/j2sdk1.3/include -I/usr/lib/j2sdk1.3/include/linux HelloWorldImp.c
gives .o file
gcc -shared -o libhello.so HelloWorldImp.o
gives .so file
then run java with the command in my first message. It works.
Thanks for the reply "thedracle".

How to run a java program in another folder

Hello!
I want to run for example the java class file in the path ./sourcecode/javafile.class. It works fine if I do the following:
cd sourcecode
java javafile
but it cannot work if I do:
java sourcecode/java
The error it outputs is NoClassDefFoundError.
Can someone tell me how to run a java program in another folder
thanks a lot.

You need to specify the classpath using the -cp flag when running. so instead of
"java sourcecode/javafile"
Try
"java -cp sourcecode javafile"

How many package in Java 1.1?

Do you know, How many package in Java 1.1?

Idiotic question, so here's an idiotic reply:
jar tf /path/to/java/lib/rt.jar |\
   egrep -v '^(META-INF|com/sun|sun)' |\
   sed -e 's/\/[^/]*$//' |\
   sort -u |\

   wc -lAnd if you change the last wc -l to more, you'll see the actual package names.

How i can call java program in VB2005 ?

If any one now how i can call java program in VB.net program and open it ,please i want now the way to do it by details and by examples and step step to do it ,,..

If your server does not return to the command prompt, write a java programm which starts your server and returns to the command prompt.
An example for an application like this:
import java.io.IOException;
public class StartApp
public static void main(String[] args)
if (args.length > 0)
StringBuffer cmd = new StringBuffer();
for (int index = 0; index < args.length; index++)
cmd.append(args[index] + " ");
try
Runtime.getRuntime().exec(cmd.toString());
catch (IOException ioe)
System.out.println("Error: command not found: " + cmd.toString());
else
System.out.println("Error: missing arguments");
An example for starting your server with that programm:
/usr/bin/java -jar ./StartApp.jar /usr/bin/java -jar ./myServer.jar
It works. Have fun.

How to execute a java program by clicking !?!?

Just a click to execute a java program?!!
Like the ".exe" in Windows or "x" permission in Unix ?!?!?!
How can I do that?
And how to set a java program file to display as a personal icon? (My Icon)
:-)

Well this is what I do in Windows (I use XP but it works in others):
First you have to make sure all the class files are in the same folder (duh)
Then you copy your java.exe from your jre folder into the folder with all your class files.
Finally, you create a shortcut to java.exe and add your class name to the command line on the shortcut.
Now all you have to do is double click on the shortcut and your program runs. Sure it's not that pretty but it works.

URGENT: How to run a Java program from a different directory?

Hi.
How do I run a Java program from a directory that the file is not located in? So lets say im in c:\Java. But the file is in c:\Java\abc\efg\.
What would be the command to run the Java file from c:\Java.
I can't remember it and I need it asap.
Cheers.

If the class you are trying to run is MyApp.class, try
c:\Java\>java -cp abc\efg MyAppThe actual classpath you specify will depend on whether or not MyApp.class is in a package (I've assumed it isn't) and whether or not any 3rd party jars are involbed (I've assumed not).
Edited by: pbrockway2 on Apr 1, 2008 6:42 PM
The command arguments read as "Run the MyApp class using as a classpath abc\efg relative to here (c:\Java)".

How to use another java program to stop this running prpgram???

Dear Sir:
I have following code and I run it success,
import java.util.*;
import java.awt.event.ActionEvent;

    System.out.print("Please enter \'C\' or \'R\' for that: ");
    BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
    String ans = in.readLine();
    System.out.print("Please enter ans=" + ans + " IsTrue= " + (ans.equals("R") || ans.equals("r")) +"\n");

    else{
      System.out.println("Invalid Entry.");
      System.exit(0);
    System.exit(0);
}But I hope to use another java program to stop it when it is running instead of pressing CRTL + C to stop it.
How to do it??
Any example??
Thanks a lot!!

Sorry, I think i did not express cearly. It is my fault.
I re-write my requirements again:
I have
Class AAA1.java,
Class AAA2.java,
Class AAA3.java,
Class AAA20.java...
etc
they all look like the program I posted first time,, once executed, they will run for ever, and they will be stopped until I press CRTL + C;
Now I hope to use another java class StopProgram.java to stop them 1 by 1 or at once instead of pressing CRTL + C;
In this case, how to code this StopProgram.java ??
Thanks

How to run a java program without Java Compiler

I have a small project and I want share it with my friends but my friend'pc have not
Java compiler.
for example, I writen a application like YM, then 2cp can sent,receive messege. My cumputer run as Server, and my frien PC run as client.
How can my friend run it? or how to create an icon in dektop tu run a java program..??..
(sorry about my English but U still understand what i mean (:-:)) )

To run a program you don't need a Java compiler. Just the Java Runtime Engine. That can be downloaded from the Sun website and comes with an installer.
You could then turn your application into an executable jar file and start it somehow like jar myYM.
There is also software that packs a Java program into an executable file. I've never used that but one that comes to my mind is JexePack. It's for free if you can live with a copyright message popping up every time you start the program.

How to run a java program via a batch file,which is called from a webserver

REM This batch file runs the Spider with the [-v] option.
REM Lines 51 through 54 are simple DOS commands..they call the Spider
REM The location of the Spider package is the important piece of information here...
REM a batch file has access to the whole computer where the server resides.
setlocal
set JDK=C:\j2sdk1.4.1_01
set PATH=%JDK%\bin;.;%PATH%
CLASSPATH=%JDK%\jre\lib\*.jar;.;%JDK%\jre\lib\ext\*.jar;.;%CLASSPATH%
java spiderpackage.EntryPoint -v
endlocal
I am trying to call this batch file from my web server but I am unable to capture the result.I tried to append the result to a file but It writes nothing to it.What should I do to proceed?

I am not entirely sure if this is analogous, but I once wrote a PHP script uner Linux that invokes java and returning the output. I found that it was necessary to pipe the output of the Java program from stderr to stdout in order to properly receive it in PHP. The command would be as follows:
java spiderpackage.EntryPoint -v 2>&1
The pipe syntax (2>&1) should be exactly the same under MSDOS. So add that, and then continue as normal (appending it to a file or whatever else you want to do). Hope that helps
