    Default How can I have a jar file on my gui?

    Basically, on my GUI, I want to have a jar file also, so it'll look like this:

    How would I do that?

    Please keep in mind, I'm new to Jframe & GUI making, I normally use console, but this is a must to do this.

    If i understand correctly, you want to run an app inside your app?

    package yourpackage;
     
    import java.io.IOException;
    import java.io.InputStream;
    import java.util.logging.Level;
    import java.util.logging.Logger;
     
    public class YourClass {
     
        public static void main(String[] args) {
            try {
                Process jarProcess = Runtime.getRuntime().exec(new String[]{"java", "-jar", "Path To Your .jar File"});
                jarProcess.waitFor();
                InputStream inputStream = jarProcess.getInputStream();
                byte[] inputByte = new byte[inputStream.available()];
                inputStream.read(inputByte, 0, inputByte.length);
                System.out.println(new String(inputByte));
            } catch (InterruptedException ex) {
                Logger.getLogger(YourClass.class.getName()).log(Level.SEVERE, null, ex);
            } catch (IOException ex) {
                Logger.getLogger(YourClass.class.getName()).log(Level.SEVERE, null, ex);
            }
        }
    }

    You can try this, new String(inputByte) is the console output text of the selected .jar.

    }

    That's only starting it...

    I can do that with getruntime, I want to load it on my JFrame, not as a regular executable.

    Ok so the one you want to load has a graphical interface or it just outputs to the console?

    Basically I want the applet to load on my graphical user interface like this.
    JFrame myFrame = new JFrame("test");
    myFrame.setSize(850,700);
    myFrame.setDefaultCloseOperation(WindowConstants.E XIT_ON_CLOSE);
    myFrame.setVisible(true);
    //Load jar on GUI here.

    Yes i understand that but are you trying to load another gui inside a gui or are you trying to load the output/console of the jar inside a gui?

    I suppose, I'm trying to load a .jar on my GUI (JFrame), in other terms a GUI in side a GUI I guess.

    Default Re: How can I have a jar file on my gui?

    Ok Java is bundled with a utility called AppletViewer

    import java.applet.*;
    import java.awt.*;
    public class Myapplet extends Applet{
    	String str;
    	public void init(){
    		str = "This is my first applet";
    	}
    	public void paint(Graphics g){
    		g.drawString(str, 50,50);
    	}
    }

    HTML Code:
    <HTML>
    <BODY>
    <applet code="Myapplet",height="200" width="200">
    </applet>
    </BODY>
    </HTML>
    C:\javac> javac Myapplet.java

    C:\javac>appletviewer Myapplet.html

    and the output is
    applet.gif

    _gaq.push(
    ['_setAccount', 'UA-5573417-2'],
    ['_trackPageview']

    (function() {
    var ga = document.createElement('script');
    ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';

    C:\javac> javac Myapplet.java

    C:\javac>appletviewer Myapplet.html

    and the output is

    That's not what I want lol, I basically want another java applet running on that gui where it says 'this is my first java applet', get it? :/

    The applet class extends the Panel class and an instance of the applet class could be added to any container.

    Create an instance of a JFrame, create an instance of the applet and add it to the JFrame. Call the appropriate applet methods like a browser would and you should be able to "execute" an applet in the GUI provided by a JFrame.
    If you don't understand my answer, don't ignore it, ask a question.

    Are you asking how to use the Swing components of one jar in a JFrame you have created? You need access to the API of the jar, to add the jar to your classpath, and then construct the appropriate components based upon the API and add them to your JFrame as you would any other component. If all you have is a jar with no documentation, you do not know the class file structure, and thus cannot construct the appropriate objects to add to your user interface.

    Could you please give me an example?

    The code could be something like this:
    Applet anApplt = new Applet();  // Create an instance of the applet
    JFrame jf  = new JFrame();        // create frame to show applet in
    jf.add(anApplt);          // add instance to jframe
    anApplt.init();              // call applet's init
    If you don't understand my answer, don't ignore it, ask a question.
