Thread: How to call the executable jars using Jbutton

Could you please any one of them explain how run the executable jar files using JButton from another class file.

I need, when i click the button then the executable jar file should be and display the output.

Thanks!

Either put the jars on your classpath and call their main method, or use a ProcessBuilder to run the jars from the command line.

Post an MCVE showing exactly where you're stuck, and we'll go from there.

1) add an action listener to the JButton
2) in the ActionListener implementation
a) Create a process using ProcessBuilder or Runtime.exec or and get the results
b) Read in the jar contents using reflection, calling the appropriate method

My jar file name is test1.jar (run able jar file)

how to call a run-able jar file (test1.jar) when i select the Radio button (Test1) in swing
could you please send me a sample code for how to call the jar file using ActionListener'

Here is my code:

import java.awt.*;
import java.awt.event.*;

import javax.swing.*;

public class Convertor {

private JFrame mainFrame;
private JLabel headerLabel;
private JLabel statusLabel;
private JPanel controlPanel;
static String str="";

public Convertor(){
prepareGUI();
}

public static void main(String[] args){
Convertor swingControlDemo = new Convertor();
swingControlDemo.showRadioButtonDemo();

}

private void prepareGUI(){
mainFrame = new JFrame("Define.xml");
mainFrame.setSize(400,400);
mainFrame.setLayout(new GridLayout(3, 1));
mainFrame.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent windowEvent){
System.exit(0);
}
});
headerLabel = new JLabel("", JLabel.CENTER);
statusLabel = new JLabel("",JLabel.CENTER);

statusLabel.setSize(350,100);

controlPanel = new JPanel();
controlPanel.setLayout(new FlowLayout());

mainFrame.add(headerLabel);
mainFrame.add(controlPanel);
mainFrame.add(statusLabel);
mainFrame.setVisible(true);
}

private void showRadioButtonDemo(){
headerLabel.setText("Select the Standard");

final JRadioButton Test1 = new JRadioButton("Test1");
final JRadioButton Test2 = new JRadioButton("Test2");
Test1.setMnemonic(KeyEvent.VK_C);
Test2.setMnemonic(KeyEvent.VK_M);

Test1.addItemListener(new ItemListener() {
public void itemStateChanged(ItemEvent e) {
statusLabel.setText("Test1 RadioButton: "
+ (e.getStateChange()==1?"checked":"unchecked"));
}
});

Test2.addItemListener(new ItemListener() {
public void itemStateChanged(ItemEvent e) {
statusLabel.setText("Test1 RadioButton: "
+ (e.getStateChange()==1?"checked":"unchecked"));
}
});




controlPanel.add(Test1);
controlPanel.add(Test2);
//Group the radio buttons.
ButtonGroup group = new ButtonGroup();
group.add(Test1);
group.add(Test2);
mainFrame.setVisible(true);
}
}

Thanks!

When posting code, please use the highlight tags to preserve formatting.

We gave you a few suggestions. What happened when you tried one of them? What exactly are you confused about?

Which part is confusing you? Do you know how to add an ActionListener to a JButton? If not, start there. Google is your friend.

If you do know how to use ActionListeners, then we've given you a few ways to call a jar from an ActionListener. Which approach have you tried? What are you confused about that approach? Where is your updated code?
