Launching IE from Java

Hi,
My requirement is as follows:
I must be able to launch Internet explorer from Java. Also i must be able to open a pdf file inside it (embedded inside IE i.e. acrobat reader inside IE).
I have tried using OleControlSite object, but does not work ( i mean it does not launch IE). I have also tried using exec. Here, how do i open ? What are the parameters that need to be passed to exec? i have tried the following code.....
String WIN_PATH = "rundll32";
String WIN_FLAG = "url.dll,FileProtocolHandler";
String cmd = WIN_PATH + " " + WIN_FLAG + " " + "c:\\NYSE Glossary.pdf";
try {
p = Runtime.getRuntime().exec(cmd);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
This piece of code opens the pdf file in acrobat reader(stand-alone). But i want the file to be open inside IE(acrobat embedded inside IE).
Can anyone suggest me a solution?
Thanks and Regards,
Kris

i have done the same thing.. it just opens the pdfin
acrobat reader.. not as part of IEThat has nothing to do with the code... you need to
install Acrobat plugin in IE. :)Annie. Have you changed login?

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();

Launching Browser from Java when Browser URL is very long

Hi,
I am trying to launch a browser from Java.
I am doing the following.
String command = "cmd" + "/c" + "start" + " browserURL";
Process p = Runtime.getRuntime()exec(command);
Note: My browserURL is very long.
Now the browser is invoked. But the URL shown is incomplete and hence
browser is unable to open the required application.
Can someone help me in this.
One way is to increase the buffer size on the command prompt?
Is there any java command for this?
Is there any other way to solve this issue.
Thanks,
AR

this is my second time posting this, take note of it. I can't remember where i got it from, but credits go to the person that wrote it. It has helped me out thousands of times!!!

Launching command containing pipe from Java

Hi,
i have some troubles to launch a command containing pipe from java.
I've tried to backslash the pipe but it still not work.
Maybe someone has an idea about that :
head -102050 /data/a_very_big_file | tail -5
the idea is to get 5 lines in the middle of a very big file.
To launch commands from java i use i think the classical way,
something like :
Process p = Runtime.getRuntime().exec(commande[0], this.envp, new File(this.pathExecution));
I obtain this error :
ERROR : head: invalid option -- 5
ERROR : Try `head --help' for more information.
Thanks for your help,
kevin.

kevleb wrote:
yes same result...
but i think the problem come from the fact
that when you pipe your result of a command,
you launch an other process (is that true).i don't know if another process is launched (the probability is rather high, though)
but even if that's the case, from the time you rely on a shell and not directly on exec(), i think it shouldn't be a problem to include a | inside the command ; i don't have an idea why it gives you that message error :\

When I try to System.exec() a program that doesn't exist, I get the following:
java.io.IOException: foo: not found
Note that foo (the program I tried to exec) is not in quotes. Check the strings you are passing to exec() to make sure there are no extra quotes. It's possible the difference in format is due to different java versions, but the point is to sanity check the strings you're passing.

Launching applications (use Java or is it possible in C)

I'm a very newbie programmer in university still...
In any case i'm only fimilar with C, C++ and Java. I'm trying to create a program that takes arguments from the command line, then launches the program identified in the command line.
I know I can launch programs from java applications with: Runtime.getRuntime().exec
but i'm not sure how a Java program would recieve arguments from the command line.
I was thinking C or C++ might be more feasible, however i don't know how to lauch applications from within either language. I hear it's pretty easy to do what i'm asking with Visual Basic (but as I said I don't know it).
Any help?
Thanx in advance.

but i'm not sure how a Java program would recieve
arguments from the command line.Strange as it might sound, through the arguments of the main method:
public static void main(String arguments[])

Easiest way to launch a link to the default browser from java?

Is there an easy way to launch a link in the default browser from java? Ideally I would have a graphic in a cell that when clicked on would open a new window/tab in the default browser. This would be done in SWT, but it might be similar to swing, awt, etc. Any ideas?

If you are using Java 1.5 or earlier, I found the browser launch code found here to work fairly well: http://www.centerkey.com/java/browser

How to launch executable from a java program

In c++ we can use a function WinExec to execute exe from a c++ program.
Is there a way to launch executables using java program. Lets say I have one executable with name "myexecutable.exe" and a java program "myprogram.java". How can I launch "myexecutable.exe" from the java program.
Is there a way to do this in Java?
Vijay

>>
class LoadExecutable

Runtime r = Runtime.getRuntime();
Process p = r.exex("winword.exe");

- ManikantanBoth of these aren't good ideas - neither of them
deals with the input or output streams at all.
Everyone who's posted to this thread should read this.
None of you knows how to use Runtime.exec properly:

How to pass Objects from Java App to JavaFX Application

Hello,
New to the JavaFX. I have a Java Swing Application. I am trying to use the TreeViewer in JavaFX since it seems to be a bit better to use and less confusing.
Any help is appreciated.
Thanks
I have my Java app calling my treeviewer JavaFX as
-- Java Application --
public class EPMFrame extends JFrame {
Customer _custObj
private void categoryAction(ActionEvent e)   // method called by Toolbar
        ocsCategoryViewer ocsFX;    //javaFX treeviewer
        ocsFX = new ocsCategoryViewer();    // need to pass in the Customer Object to this Not seeing how to do it.
                                              // tried ocsFX = new ocsCategoryViewer(_custObj) ;    nothing happened even when set this as a string with a value
public class ocsCategoryViewer extends Application {
String _customer;
@Override
    public void start(Stage primaryStage) {
     TreeView <String> ocsTree;
     TreeItem <String> root , subcat;
TreeItem <String> root = new TreeItem <String> ("/");
        root.setExpanded(true);
         ocsTree = new TreeView <String> (root);
         buildTree();     // this uses the Customer Object.
        StackPane stkp_root = new StackPane();
        stkp_root.getChildren().add(btn);
        stkp_root.getChildren().add(ocsTree);
        Scene scene = new Scene(stkp_root, 300, 250);
        primaryStage.setTitle("Tree Category Viewer");
        primaryStage.setScene(scene);
        primaryStage.show();
    public static void main(String[] args) {
        _customer = args[0];      // temporarily trying to pass in string.
        launch(args);

JavaFX and Swing integration is documented by Oracle - make sure you understand that before doing further development.
What are you really trying to do? The answer to your question depends on the approach you are taking (which I can't really work out from your question). You will be doing one of:
1. Run your Swing application and your JavaFX application as different processes and communicate between them.
This is the case if you have both a Swing application with a main which you launch (e.g. java MySwingApp) and JavaFX application which extends application which you launch independently (e.g. java MyJavaFXApp).
You will need to do something like open a client/server network socket between the applications and send the data between them.
2. Run a Swing application with embedded JavaFX components.
So you just run java MySwingApp.
You use a JFXPanel, which is "a component to embed JavaFX content into Swing applications."
3. Run a Java application with embedded Swing components.
So you just run java MyJavaFXApp.
You use a SwingNode, which is "used to embed a Swing content into a JavaFX application".
My recommendation is:
a. Don't use approach number one and have separate apps written in Swing and Java - that would be pretty complicated and unwarranted for almost all applications.
b. Don't mix the two toolkits unless you really need to. An example of a real need is that you have a huge swing app based upon the NetBeans platform and you want to embed a couple of JavaFX graphs in there. But if your application is only pretty small (e.g., it took less than a month to write), just choose one toolkit or the other and implement your application entirely in that toolkit. If your entire application is in Swing and you are just using JavaFX because you think its TreeView is easier to program, don't do that; either learn how to use Swing's tree control and use that or rewrite your entire application in JavaFX. Reasons for my suggestion are listed here: JavaFX Tip 9: Do Not Mix Swing / JavaFX
c. If you do need to mix the two toolkits, the answer of which approach to use will be obvious. If you have a huge Swing app and want to embed one or two JavaFX components in it, then use JFXPanel. If you have a huge JavaFX app and want to embed one or two Swing components in it, use a SwingNode. Once you do start mixing the two toolkits be very careful about thread processing, which you are almost certain screw up at least during development, no matter how an experienced a developer you are. Also sharing the data between the Swing and JavaFX components will be trivial as you are now running everything in the same application within the virtual machine and it is all just Java so you can just pass data around as parameters to constructors and method calls, the same way you usually do in a Java program, you can even use static classes and data references to share data but usually a dependency injection framework is better if you are going to do that - personally I'd just stick to simply passing data through method calls.

Problem when connecting locally to Oracle Database 10g from Java code

Good afternoon,
I try to connect to my local Oracle 10g from JAVA code. Could somebody tells me what are the 'values' to enter in place of 'value1, value2, value3' in the following:
final String connectionURLThin = "jdbc:oracle:thin:@value1:value2:value3";
I tried to put my 'user' and 'pw' credentials I used when connecting with SQL*PLUS:
value1=my_user_name
value2=my_pw
value3=my_schema
but it doest work. Besides where could have I to put the 'WORKSPACE" name?
Thanks for any help.

Yes, the network connection could not be established. Like the error said.
What you're asking about is the exact reason, but that could be any number of things and not at all related to code. You could have the wrong host, the wrong port. A firewall could be blocking the outgoing connection, a firewall could be blocking the incoming connection. Etc. etc.

Calling back c++ method in an exe (not a dll) from java?

Hi all,
I have to make an hybrid C++/java from an existing C++
application that compiled is a big single exe not a dll.
I'm running under win32.
The application consists of several windows. The hybrid
will have widows in C++ and some in java. They have the
same menu and tool bar. In the C++, there are some
callbacks called when a button is pressed. How to call
these callback from java given the fact that the JVM and
the java classes are launched by the exe file.
I know how, from C++, start JVM and call my java window.
I also know how to call a C++ method that is in a dll from
java. It's from the tutorial
http://java.sun.com/docs/books/tutorial/native1.1/index.html
But I don't know how to call a C++ method that is in in an
exe which has launch a JVM from an object running in this
JVM.
Is there somewhere an example like this?
Thanks,
Xavier.

Thanks this helped.

Execute a Linux konsole command from Java

Hy,I am having problems when trying to execute a command for konsole from java.
This is a part of my code
try {
Runtime.getRuntime().exec("konsole");
catch (IOException ex) {ex.printStackTrace();}this code opens the Linux konsole ; is the a method to append a command for Linux from java??
Thanks

OK
this is what I am trying to do : by pressing a button
in a JFrame I want to start Snort (the exact command
is snort -c /etc/snort/snort.conf )
What I want is the following: I press that button
and the Konsole in Linux opens and that command to
be executed I would just use the Process.getInputStream() method to retrieve what Snort said and display that in a JTextArea or something... why bother launching it in a terminal?
I don't know if Snort is a daemon or what... if it's a daemon, you're not going to get much output from it... it'll fork itself into the background and exit.
If it isn't a daemon, then you can either just redirect the output to a file, a la:
konsole snort /etc/snort/snort.conf > /tmp/snort.outand do a "tail" sort of monitoring on the file. You could also just keep that process up in a different thread, and use a timer to periodically update the output into a JTextArea (this would also allow you to be notified when the process ended). Finally, you could wrap your command in a script and execute it that way.
