Running linux applications in Java

I'm doing a project for an application to do wireless mapping, using existing open-source programs (like Kismet and TCPdump).
My problem is that I need to launch linux applications in super user mode from my java program, but I don't know how! I was using Runtime.getRuntime.exec() to launch applications (something like this):
Process prsc;
Runtime rt;
public boolean openApp(String app){ //app is a string with the application to open
try{
rt=Runtime.getRuntime();
prsc=rt.exec(app);
} catch(IOException e){
return false;
return true;
and then using prsc.destroy() to kill the open app.
This was working fine with gedit (used for testing) but now I need to open Kismet wich needs to be open with super user permissions. Anyone know how to do this?
Jo�o Guilherme

Use sudo, e.g. sudo -p passwd kismetYou
need to look up the exact syntax, obviously. Have
your Java program ask the user for the password.You will also need to add the user to the 'sudo'ers list.

Unable to run my application using java web start

i have created one application and use java web start to download the application. all the files are succesfully downloaded but when i try to run the application an expected error occur. this only happen in my machine but not in other machine i'm currently using
-jsdk1.4.2
-windows 2000 professional 5.00.2195 service pack 3
-pentium III 870 Mhz
-x86-based PC
-RAM 256 Mhz
Anyone knows why, plz help me with this puzzle

Please post the information from the Web Start "Exception" and "Wrapped Exception" tabs when the error occurs (I assume the error was in fact unexpected ;-)
A blind stab in the dark would be that you don't have write permission to the cache directory on the second machine. Also worth checking that the proxy settings on the second machine are the same as the first (if they are on the same network).

Help running an application with java

public void actionPerformed(ActionEvent event)
      if (event.getActionCommand().equals("Application"))
          getContentPane().runApplication(Application);
}What would replace "runApplication(Application)"?
Thanks.

What on earth are you trying to do with that code?
Do you just want to execute an external application via java, such as with the Runtime.exec() method?
try {
   Runtime.getRuntime().exec(...);
} catch ( ... )Something similar to that?

Running a Linux application from Java

Hy,
I am working at a faculty project and I need your help
What I want to do is by clicking a button, in a JFrame I want to open an application ,for example Mysql Query browser. I am using FC 6 and Netbeans 5.5
Can you help me??
Thanks

can I open the konsole from java??Yes.
First you must figure out how to do that from the command line yourself. That has nothing to do with java.
Note that that how you do that MUST account for the fact that the "command line" is actually a shell. Some commands must be run by running the shell as the actual command and then passing the desired command as an option to the shell (the actual command.)
Again you can google for examples.

Running and application without java

Hi,
I have made an application installer (in java) for my project..
My concern is that how can i run my installer on a machine that doesnt have java installed on it,, possible solution could be to bundle the jre withmy installer and via batch file set the path pointing to my jre..but I dont want the black cmd line window to be appeared..
By the way install shield and other installers uses their own jre ,, I want to know how do they do that..
Thanks in advance
Dexter108

I very much doubt you can do what you want. How can a Java program run without Java installed ? It is not possible.
If Install Shield, etc do it somehow as yourself 'Are these programs written in Java or some other language?' I suspect they are written in C++ and so can do what they like as far as being able to install a JRE because they are not dependent on Java being installed.
You would be better Zipping up all the files you need (including the JRE installer) and using this as the installer. This would at least provide the user with all files required. They can then manually run the JRE installer and once they have done this your app should work.

Running an application from java

Hi all,
Can someone help with this. It is a calculator application using the unix bc calculator program to evaluate the expression.
I get no results form this code. The application hangs. Where have I gone wrong.
public void calculate() {
        try {
            exp.append("\\r\\n");   // add carriage return to the end of the expression
            Process p = Runtime.getRuntime().exec
                    ("bc -qi");
            BufferedWriter output = new BufferedWriter(new OutputStreamWriter(p.getOutputStream()));
            BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream()));
            output.write(exp.toString());
            while ((result = input.readLine()) != null) {
                System.out.println(result);
            input.close();
            p.destroy();
        } catch (Exception err) {
            err.printStackTrace();
    }thanks,
Sebastian

Thanks.
changing to
exp.append("\n");and flushing the writer stream and closing the stream fixed the problem.
Why do we have to flush the stream?
and, why do we have to close the writer before reading? what if I want to continue writting in to the writer?
thanks again.

Not getting application in Java Web Start

Hello Sir,
I wanted to run an application using Java Web Start. So, I created a jnlp file and i have mentioned the necessary jar files and the main class file. when I clicked on the jnlp file, the application is running in the Server using Java Web Start and its shortcuts are creates on the desktop and in the startmenu. I am able to run the application by clicking on the shortcut in the server. But I am unable to Download the application in the Java Web Start. It is not showing any Error Messages and the application is not running in the cleint machines.
The contents of the jnlp file is as follows.
<?xml version="1.0" encoding="utf-8"?>

<jnlp

"I am unable to Download the application in the Java Web Start"
If webstart in not actually downloading the jar - is the jar in the correct location?
Is the server named dev01 and the directory structure actually /Dummy/New?
Note: you do need to set up the mine type JNLP on your server,
In my case the location of the JNLP file and main jar file passport is in the following directory.
c:\Inetpub\WIMRoot\application
The additional jars are in
c:\Inetpub\WIMRoot\application
I hope this may give you some clue

Hi,
When we run standlone application using "java" in comand promt there are some options like
-D, -X etcs.
I'm trying to run a application but not able to find out the parameters passing.Can some body explain it in details....like what -Dmq.port,-Dmq.host ,-Dlog.configuration etcs tends for....

Hi !
Don't know for sure...but my guesses are:

-Dmq.port=1414 Port used or contacted by the program
-Dmq.channel=TO.MQCAUXT1 Channel used or contacted by the program

The ones above are just guesses from the names of the parameters...for better answers you should contact the guys at steelroads.com

How to run native program with Java program?

Hello
I've got following problem. I'd like to write file browser which would work for Linux and

Try this:

Process proc = rt.exec("ls -l");
InputStream stream = proc.getInputStream();
InputStreamReader isr = new InputStreamReader(stream);
BufferedReader br = new BufferedReader(isr);
String line = null;
while ( (line = br.readLine()) != null) .....

Getting GTK error while running javaFX application on linux

I developed an JavaFX application that works fine on Windows. So, I tried to run this same application on Linux (ubuntu x86) and it is not working.

I get the same message, when running my application in stand alone.
May be there is a problem when running in aa KDE environment.
But I developed my app in Eclipse under KDE4. If the app is started by IDE it runs.

How to run an application i created in java without using eclipse

Im familiar with running an application i create thru command prompt or eclipse, how do i create a file to run on any computer with java so i can double click the file and my application runs. C# automatically does this, do i need to do an extra step to the jar file?

Hi,
You need to make an executable JAR file. There are a few ways you can do this but since you are using Eclipse you can follow this tutorial.
[http://www.fsl.cs.sunysb.edu/~dquigley/cse219/index.php?it=eclipse&tt=jar&pf=y]
The most important part is the manifest file, if you have dependencies on other JAR files they will need to be specified along with the
main method to call to start you program. You can do this via the Eclipse Wizard.
It will be in your interests to read this tutorial also
[http://java.sun.com/docs/books/tutorial/deployment/jar/]
