Launching An Application From Java applet?

is it possible to run an executable from a java applet (the executable could be in the local machine)? if it is not possible is there any other alternatives (like scripts)?

Yes, it is possible but it violates the applet security rules. So you have to sign the applet for this to be allowed.

How to launch an application from java?

Hi,
Would anybody please help me this. I need to launch a new desktop application from my java app but I don't know how. For example, when user clicks on a "Edit" button from my java app, my app needs to launch NOTEPAD.EXE to allow user starts editing.
Thanks a lot.
Hung.

try something like this for your button's action method:
        String[] cmd = {"notepad"};
Runtime rt = Runtime.getRuntime();
        try {
            Process pro = rt.exec(cmd);
            pro.waitFor(); // wait until it's done executing
            System.out.println("Process exit code is: " + pro.exitValue());
        }catch(IOException ioe) {
            System.err.println("IOException -> " + ioe);
        } catch(InterruptedException ie){
            System.err.println("InterruptedException: " + ie);
        }

Can not launch swing application from Java Web Start 1.6.0_37

I have a dynamic generated jnlp file from a serlvet. When I used Java Web Start to start the swing application, it failed. The exception showed

I used janela to validate the generated jnlp file. It was valid. I also checked the tomcat access log, it showed that the Test-1.0-SNAPSHOT.jar file was accessed correctly (with a 200 return code).
Can anyone help me what was the problem?
Thanks,

Launching applications from an applet

How do you launch applications from an applet? For example,launch a notepad exceutable when you click on a button (an awt component)?

Hi,
you can launch an application from the applet using the Java RunTime environment.
Runtime.getRuntime().exec(applicationName);
But to do this the applet needs permissions.It should be a trusted applet.

Launching application from an applet

Can someone please tell me what are the ways I can launch an application from an applet? Can you provide some examples, etc.
Thanks,
Syed

If you want to run an application, all you have to do is call it's main() method.
public class AppApplet extends JApplet {
    public void init() {
        JButton button = new JButton("Start App");
        this.getContentPane().add(button);
        button.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                String[] args = ...;
                AppClass.main(args);
public class AppClass {
    public static void main(String[] args) {
        //Do whatever
}

Launching applications from java code

I have found a solution to launch applications from java.I thought this will be useful for programmers who want to open a
1. Browser
2. Player
3. Files etc.
There are 2 solutions :
I)To use a known application :
eg: to open windows media player
String[] cmd = new String[3];
cmd[0] = "cmd.exe";
cmd[1] = "/C";
cmd[2] = "START MPLAYER2.exe "+mediaURL+" /PLAY /CLOSE /FULLSCREEN";
//eg: mediaURL = "\"D:/project/songs/track1.mp3\""
// /PLAY /CLOSE /FULLSCREEN this option can be used only for windows media player
// for any other application use cmd[2] as START apl.exe //apl can be any windows application
Process p = Runtime.getRuntime().exec(cmd);
II) To use a default application:
Runtime.getRuntime().exec("rundll32 url.dll,FileProtocolHandler " + url);
// url can be any url

To post code, use the code tags -- [code]Your Code[/code] will display asYour CodeOr use the code button above the editing area and paste your code between the {code}{code} tags it generates.
And make up your mind what file type you're having a problem with. Maybe .asx doesn't have a file association on your computer.
This works just fine for .m3u:import java.awt.Desktop;
import java.io.File;
import java.io.IOException;
public class Playlist {
   public static void main(String[] args) {
      try {
         Desktop.getDesktop().
               open(new File("E:/Music/Playlists/test.m3u"));
      } catch (IOException ex) {
         ex.printStackTrace();

How to launch an app from Java in Mac OSX?

I would like to launch another application from my Java code which will run on OS X. Doesn anyone know how to do this? I think it involves the "Runtime.getRuntime.exec()" method, but I'm not sure how to tell it which application to launch.
Thanks

I dont know about OSX but i can give you a generalized
solution. In all OS's there will be a way to get to
command prompt. It is not really true: MacOS is one noticeable exception! Version 9, like every previous one, was completely extraneous to the notion of "command prompt", because the Macintosh, since its origin to nowadays, has been a "fanatically" User-Centric system: everything is iconic. A side effect of this approach is that MacOS was a pretty hard platform for low-level developers...
In MacOSX things have dramatically changed: this OS is a powerful Unix-like one, with the beautiful dress that only a Mac can wear: and finally, all you Mac users, here it is: the shell!
Of course, in MacOSX (and in MacOS "classic" too) there are paths and executable files.
MacOS1-9 file-system was a very peculiar one: resource fork and data fork for every file, ":" as path components separator (but what "common" user has ever seen a Macintosh path?) and so on.
MacOSX will use an Unix-like filesystem, I guess (I'm not a Mac user, I like every OS for its beauties - and therefore dislike Microsoft products even if often they give me bread).
But the key question is: how do I tell the runtime which file it has to execute?
Fortunately, every modern SO I know adopts a hyerarchical organization of its files. So, indipendently of what is considered the "root" ("C:\", "/" or whatever else), you can "trace" a relative path from your current path (if you use an Unix or URL idiom, "./") and the file you want to reach.
So, if your java app ("JavaApp.class") is placed in a folder called "MyJavaApp", nested in another folder called "Programs" that you see when you click on the "MacHD" icon, and you can manually launch the Mac app you're interested in clicking on an icon called "MyMacApp Program", placed in a folder called "MyMacApp", nested in another folder called "Programs" that you see when you click on the "MacHD" icon (it's the same folder we said before :-) ), using Unix or URL sintax we have that:
your java application is at: [...]/MacHD/Programs/MyJavaApp/JavaApp.class
the Mac application is at:
[...]/MacHD/Programs/MyMacApp/MyMacApp Program
The relative path from the former to the latter is, therefore:
../MyMacApp/MyMacApp
where two dots ("..") are the symbol for "parent folder".
If the situation is similar to above, the code to launch MyMacApp should be something like this:
import java.io.File;
File currentDir=new File("");
//supposing that double dot (..) is the symbol for "parent folder"
Runtime.getRuntime(
     new File(currentDir,".."
     +File.separator
     +"MyMacApp"
     +File.separator
     +"MyMacApp Program"
     ).getAbsolutePath()
in a more portable fashion - if you're not sure ".." works
(? who cares? we're launching a native app :-)) )
Runtime.getRuntime(
     new File(currentDir.getParent(),
     "MyMacApp"
     +File.separator
     +"MyMacApp Program"
     ).getAbsolutePath()
);Hope it works... good work!

How to call a VB application from Java

Close a running application from java........

Hi all
I have opened an application say MSWORD from my java class using Runtime.getRuntime(), Now on close button i need to close the application and on the save button of the application i even want to save the application from java command
The question is HOW????
please reply,
Thanx,
Amitt

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.

Launching an application from Applet

Can anyone tell me if it is possible to launch an executable file (.exe) from an applet? If so how does one do it?
Thanks!

One of the points of applets is that they are not suppose to be able to execute local programs. If you could naughty people whould create applets that formmated peoples hard drives.
however, there is something called signed applets that may or may not give you more flexibility. I suggest reading up on them.

Calling a WebService from Java Applet

Hi all,
In my application I have 3 projects:
1. server - for all the business logic.
2. view - for web app.
3. swing - for applet.
In the view project I wrote a WS, and I want to call it from my applet. So I created a WS using the Jdev (10.1.3.2) wizard in the view project (I tested it and it worked fine), and in the swing project I created a proxy for this WS, tested it and it worked fine. Then I created a JAR containing the swing project with the WS proxy classes, opened the Applet and find out that I have some classes missing, so I started adding all the relevant Jars and ended with a ~13MB JAR containing all the swing project jars that in the class path for a simple Applet.
I know that I'm missing something but I dont know what. Do I really need all those Jars. Is there a simple way to call to a WS via Applet?
This is the list of all the Jars:
activation.jar
commons-logging-api.jar
commons-logging.jar
ejb.jar
http_client.jar
jaxb-api.jar
jaxb-impl.jar
jaxen.jar

Try this:
1. open the webService data controll in the Data Controls section and drag the method from the webService onto the method call activity in your task flow. This will overwrite the current method property (the one which pints to your bean, make a copy of this entry if you can't reproduce it by hand). This too will create an entry in the pageDef of the method call activity.
2. reenter (or paste) the original value in the method property, so that it again points to your bean. The entry in the pageDef will remain!
3. now in the bean method you can access the method via its binding like you access any other method from the binding:
// GET A METHOD FROM PAGEDEF AND EXECUTE IT
// get the binding container
BindingContainer bindings = BindingContext.getCurrent().getCurrentBindingsEntry();
// get an Action or MethodAction
OperationBinding method = bindings.getOperationBinding("YourMethodActionNAME");
if (method == null)
// handle method not found error...
// if there are parameters to set...
Map paramsMap = method.getParamsMap();
paramsMap.put("param","value") ;
// execute the method
method.execute();
List errors = method.getErrors();
if (!errors.isEmpty())
   // handle errors here errors is a list of exceptions!
// no error resume normal workTimo

Print- Save as PDF from Java applet on a webpage in Safari

Help! I want to make Wordles for the teachers at my kids school for Teacher Appreciation Week.

YES!!!!!!!
I was pulling my hair out last night over this. I noticed the Find function was not working properly. I KNEW there was something in the PDF and Preview was not showing it. I spent 2 hours trying to find someone with a similar Find function problem, but could not find much. Also, it could not copy and paste text. I KNOW it worked before because I had taken notes on this particular PDF and had copy and pasted whole paragraphs for myself into Pages. Which is what got me searching online tonight.
I re-downloaded the same PDF. When first opened in Preview, the Find and copy/paste functions worked. Same thing in Acrobat reader and Acrobat Pro. After confirming this, I re-opened it in Preview, highlighted some text and closed. It asked to Save Changes and I did. I immediately re-opened it, and guess what? Find no longer works and neither does copy/paste. Just to be sure, I tried re-opening in Acrobat reader and Pro; same thing. No copy/paste, corrupted Find feature. Well, copy/paste sort of functions, its just that it pastes a square with an alien head in it that says "Private Use 100000 Plane 16".
And finally, on some PDFs that have not even been saved in Preview, the Find function is not working properly also. It happened on the re-downloaded PDF I just talked about. It finds many instances of the word, bit the left and right arrows next to "Found on X# Pages are greyed out and do not move through the document. Once I go to the left pane that displays page thumbnails and click on a few different ones, THEN it starts working.
So yes, Apple, Preview is corrupting PDF files upon save, AND it is not working properly on other files. Please fix this. PLEASE.
And my specs are the same as Gary; iMac 27 inch Late 2009, Yosemite 10.10.1. Is ANYONE else having this issue with a different Mac?

Read, Write and create files from java applet.

Dear All,
I have created a two files. One is applet and one application file. I am creating a instance of application file in applet. Application file is used for reading, writing and creating files. When I invoke applet from broser it dipslays error wrt file access permission. From the forum search I know that we need to sign the applet / edit the java policy to run the code locally. Final delivery of my code should execute on different system. Its not web. I have created a html page on submitting the form it invokes applet to read the form values from param and needs to update the values in xml file located locally. Please help me on how I can proceed with this fix.
Thanks in advance.

Sorry if I have not stated the problem clearly. I need to update content to files hosted in local system using java applets.
I belive there are two ways to achive that.One with jar signer and one with modifying the java policy file. But this application needs to be installed in different system locally as I have created a application with webpage as useinterface and need to update the content in local files on submission. Not sure on how to modify the java.policy files in each end user system and whats the value we need to update in java policy file. Please help me on the steps to be followed
