Making exe of java file

I have a java file that contains password to log to embaded system using secure copy. So i do not wann to show that password to any one.
So can i make exe of it or any other way to hide the password.
i do not want to use jar or war because it can be easily broken

I have a java file that contains password to log to
embaded system using secure copy. So i do not wann to
show that password to any one.a native executable won't help that
So can i make exe of it or any other way to hide the
password.what makes you think an executable will do this?
i do not want to use jar or war because it can be
easily brokenjust as easily as an executable. and you can't choose between a jar and a war, you have to use whichever is appropriate for your deployment. if you are developing a web-app, how on earth is your container going to load a windows executable? and this isn't a JSP question, in any way shape or form

Oracle.exe and java.exe are running my CPU 100% under XP Prof SP3

11gR1
oracle.exe and java.exe are running 100% CPU
I have increased virtual memory to 4 gig
I have defragmented the drive.
I checked the drive for errors.
I am searching the whole drive for viruses
I do not have the problem with Redhat Fedora 12 running 11gR1
I have 1 gig of RAM but cannot install release 2 because the installer expects
1 gig + 1

ooops!!! left that off...sorry
XP Prof SP3 32 bit..*.no problem with Redhat Fedora 12 running MySQL and 11gR1*
1 gig RAM Dell precision W/S 1.5 Gig rate 74 GiG SCSI HD 15000 RPM
Don't pass out but I am also running MySQL server 5.1.41 and MS SQL Server Express 2008.
Lucky it didn't catch fire
I installed XP prof months ago but this CPU domination occurred only starting last night!
However slow everything works in 11gR1
sqlplus myname/password and then select rows from table

I've had plenty of trouble with Java running slow and hogging memory!

Babu H

example
import javax.swing.*;
import java.awt.*;
import java.awt.event.KeyAdapter;
import java.awt.event.KeyEvent;
import java.io.*;
public class RuntimeExample extends JFrame {
    private JTextArea textArea;
    private JTextField textField;
    private PrintWriter writer;
    public RuntimeExample()
        init();
        initProcess();
    public void init()
        textArea = new JTextArea(20, 80);
        textArea.setEditable(false);
        textField = new JTextField(30);
        textField.addKeyListener(new KeyAdapter()
            public void keyPressed(KeyEvent event) {
                if (event.getKeyCode() == KeyEvent.VK_ENTER)
                    if (writer != null)
                        textArea.setText("");
                        writer.print(textField.getText() + "\r\n");
                        writer.flush();
                        textField.setText("");
        Container container = getContentPane();
        JScrollPane scrollPane = new JScrollPane();
        scrollPane.setViewportView(textArea);
        container.add(scrollPane, BorderLayout.CENTER);
        container.add(textField, BorderLayout.SOUTH);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        pack();
        textField.grabFocus();
        setVisible(true);
    public static void main(String[] args) {
        new RuntimeExample();
    public void initProcess()
        Runtime rt = Runtime.getRuntime();
        try
            //Process p = rt.exec(new String [] {"cmd", "/C", textField.getText()});
            //textArea.setText("");
            //textField.setText("");
            Process p = rt.exec("cmd");
            writer = new PrintWriter(p.getOutputStream());
            Thread thread1 = new Thread(new StreamReader(p.getErrorStream()));
            Thread thread2 = new Thread(new StreamReader(p.getInputStream()));
            thread1.start();
            thread2.start();
            System.out.println("Exit Value = " + p.waitFor());
        catch (Exception ex)
            textArea.append(ex.getMessage());
            ex.printStackTrace();
    public class StreamReader implements Runnable
        InputStream is;
        public StreamReader(InputStream is)
            this.is = is;
        public void run()
            try
                BufferedReader reader = new BufferedReader(new InputStreamReader(is));
                String data;
                while ((data = reader.readLine()) != null)
                    textArea.append(data + "\n");
                reader.close();
            catch (IOException ioEx)
                ioEx.printStackTrace();
}you can pass input to the exe by using getOutputStream() from Process and get the output from getInputStream() from Process

Invoke exe through java code(using java.lang.Runtime)

Iam trying to invoke an exe from java code.If i give the complete path for that exe it is running fine .But if i set the environment variable and directly execute the exe through command prompt it iss running fine , but it fails to run when i do the same using java code i.e. java.lang.Runtime.exec function

Give "//" for directory seperator.
E.g. r.exec("c://test//test.exe",null);
Why? That doesn't look correct.It is correct. It will work fine. Try it out.But it doesn't add or solve anything. A forward slash
does not need to be escaped.'
It's not even escaping. It's just doubling up. If that works, I'd bet "C://///test///////test.exe" does also.

How to run geniatagger.exe from java

Hi,
i'm trying to run geniatagger-1.0.exe from java on windows vista, using Process pr = Runtime.getRuntime().exec("C:/geniatagger-1.0/geniatagger-1.0.exe");
However, i keep on getting the same error. "Cannot run *.exe CreateProcess error=2" . I tried the same code with excel.exe which is installed in C:/ProgramFiles
and it worked. I also tried to create a path variable C:/geniatagger-1.0/geniatagger.exe;%path% and then run the same java code. Yet, nothing has changed.
I would really apreciate any help

Calling C code (exe ) from Java program

Hi all,
kindly help in giving a solution for calling C code (exe ) from Java program, i will be very thank full to u if any body can help in sending a code example
bye

You might need to consume the io operations on the Process...
An excerpt from java.lang.Process:
All its standard io (i.e. stdin, stdout, stderr) operations will be redirected to the parent process through three streams (Process.getOutputStream(), Process.getInputStream(), Process.getErrorStream()). The parent process uses these streams to feed input to and get output from the subprocess. Because some native platforms only provide limited buffer size for standard input and output streams, failure to promptly write the input stream or read the output stream of the subprocess may cause the subprocess to block, and even deadlock.

A problem in executing exp.exe through Java

while implementing oracle schema export I am facing problem in executing the exp.exe from JAVA. Please see sample code below.
Process p=null;
ProcessBuilder pb = new ProcessBuilder ("exp.exe","username/password@dbinstance", "owner=pr01",
"file=e:/temp/pr98.dmp","log=e:/temp/pr98.log","compress=y","grants=n","STATISTICS=COMPUTE");
try{
p = pb.start();
catch(Exception e){
System.out.println("Error="+e.getMessage());
where pr01 - name of schema to export.
With this code, the actual export of the project starts only after Java application is closed and not immediately on the click of a button.
I have used Runtime.exec() tooo...The same problem is there..
Any solution?

HI
Did you fix this problem with svrmgr. I have exactly the same problem and I am runing redhat 7.2 and oracle 8.1.6
Thanks, Jason

Making .exe for a java file

Hello all, i'm much interested in making
a java file to be in .exe form without using any
IDE's available for JAVA .
Is it possible for us to make the .exe form of a
java file to be executed in a machine
which has only JRE AND JVM.

Making '.exe' file/application using JAVA

Hi,
Is it possible to make an application(an exe file) using just Java, just as we in VB.If yes can you please give some idea how can we do that.
Thanks.....

To make a java application run from a click on an icon
you must create a Jar file as I've explained below:
Create a separate folder and place all the source code programs needed to run the application in it. You just need the ones with the .class extension. You don't need the ones with the .java extension.
Open up 'Notepad' and type in this line:
     Main-Class: your class that has the main method
You don't need the .class extension.
ex. If your main method is in a program called HelloWorld.class
type in :
Main-Class: HelloWorld
Make sure you hit the RETURN key at the end of the line. I forgot to do that which is why I spent four hours trying to get this to work!
Save this as: manifest.mf
and put in the same folder as above. Make sure it doesn't save as manifest.mf.txt
     Open MS-DOS.
CD change to the directory and folder you are in.
Type this in exactly as I have written:
jar cvfm0 myprogram.jar manifest.mf *.class
     This should put a Jar file in your folder. Just click on it and it should work.
Make sure the program doesn't need to take input from a command line, like DOS.
Otherwise it will do nothing. As long as your program creates a frame, window, button or something, it should work.
     To run the Jar file from DOS(for testing purposes) type:
java -jar myprogram.jar
     If you get an error stating that it can't find the main method class(like mine did), right click on the 'myprogram.jar' file that was created,
click on properties, then ZipMagic.
Open the 'manifest.mf' file and make sure
that 'Main-Class: yourprogramname' is in there.
     If you followed these directions you should be able to create an executable java file.
Below I've explained what the commands to create the Jar file mean.
jar: means you are creating a java archive file which acts like a ZIP file
c: means create a new jar file
v: means verbose which tells DOS to show the action it is doing
f: means that the files to choose are going to be typed in by a user(you at the Dos prompt)
m: means to use the manifest file that you specify
0: means that the file won't be compressed
To make a JAR file you only need the cfm letters.
