How to open new webBrowser in java with BrowserLauncher.java

I m using BrowserLauncher.java which opens default webBrowser but i want to open new webBrowser for new request each time.
Plz suggest to me what changes i have to made in this java class.
it is very urgent???

* BrowserLauncher is a class that provides one static method, openURL, which opens the default
* web browser for the current user of the system to the given URL. It may support other
* protocols depending on the system -- mailto, ftp, etc. -- but that has not been rigorously
* tested and is not guaranteed to work.
* 
* Yes, this is platform-specific code, and yes, it may rely on classes on certain platforms
* that are not part of the standard JDK. What we're trying to do, though, is to take something
* that's frequently desirable but inherently platform-specific -- opening a default browser --
* and allow programmers (you, for example) to do so without worrying about dropping into native
* code or doing anything else similarly evil.
* 
* Anyway, this code is completely in Java and will run on all JDK 1.1(or better)-compliant systems without
* modification or a need for additional libraries. All classes that are required on certain
* platforms to allow this to run are dynamically loaded at runtime via reflection and, if not
* found, will not cause this to do anything other than returning an error when opening the
* browser.
* 
* There are certain system requirements for this class, as it's running through Runtime.exec(),
* which is Java's way of making a native system call. Currently, this requires that a Macintosh
* have a Finder which supports the GURL event, which is true for Mac OS 8.0 and 8.1 systems that
* have the Internet Scripting AppleScript dictionary installed in the Scripting Additions folder
* in the Extensions folder (which is installed by default as far as I know under Mac OS 8.0 and
* 8.1), and for all Mac OS 8.5 and later systems. On Windows, it only runs under Win32 systems
* (Windows 95, 98, and NT 4.0, as well as later versions of all). On other systems, this drops
* back from the inherently platform-sensitive concept of a default browser and simply attempts
* to launch Netscape via a shell command.
* 
* This code is Copyright 1999 by Eric Albert ([email protected]) and may be redistributed
* or modified in any form without restrictions as long as the portion of this comment from this
* paragraph through the end of the comment is not removed. The author requests that he be
* notified of any application, applet, or other binary that makes use of this code, but that's
* more out of curiosity than anything and is not required. This software includes no warranty.

Open new URL page in same window

Hi all,
I am using LinkToUrl UI element for opening a new URL
page.
I did it successfully by giving the URL in reference property.
But the link is opening in new window.It should be opened
in same window instead of new window.
Any one can help me........

Hi
Use the target property of LinktoURL .
You can specify the window name where you want to load new URL.
Check the following Link.

Cannot open MSWord while running java application

Hi everyone
I'm not sure if anyone has encountered this problem before.. I'm running a java application under Windows NT and when I try to open an office document it won't run until that java application has been shutdown. I don't even get an error message for this. Nothing happens at all until the application is shutdown and then MSWord just opens as if nothing had ever happened.
Anyone have any ideas as to what this problem might be?

As a guess.....
1. Run a "hello world" java application. Use task manager and take a snap shot of the processes window.
2. Run nothing else but the java application. Use task manager and take a snap shot of the processes window.
3. Compare the two and eliminate any that are the same.
4. Run nothing else but word. Use task manager and take a snap shot of the processes window.
5. Compare it with 3. Note the ones that appear both times.
6. Run the java application - use task manager to kill what you found in 5. Run word.
Step 6 will probably cause the java app to fail in some odd way. But now you know why it doesn't work.
Of course if nothing is the same in 5 above then that would be odd.

Opening a URL from an application

Hi everyone, am not quiet skilled with java but i would really appreciate your help with this, as i couldn't find a solution which made me doubt my whole basic knowledge of java. Now am doing this for my school project, it's a speech recognition application that will convert speech to text, there are 2 buttons in my interface, one "start" where you start speaking , the other one "stop" which would allow the engine to start processing the speech and converts it to text, it will then open a web page which in my case is a search engine(say google or yahoo) and searches for the matching documents of what has been spoken.
my problem is that i need to open that certain URL ( predefined) from a running application and not an applet, it hasn't worked for me, This is the only problem. is it possible ? please i need your help with this , i'd really appreciate it if someone would help ... thanks a lot for your time.

hii guys am really sorry for the confusion ,the problem was actually with the java security poilcy not with the code as i thought.. i thought my code was wrong but it turned out to be correct.. here it is for anyone who's interested... but thanks anyway for everything... tc
Runtime rt = Runtime.getRuntime();
rt.exec("C:/Program Files/Internet Explorer/iexplore.exe http://www.google.com/search?hl=en&q=hi+my+name+is+omaya");

Open web browser from java application to specific page

Hi,
I used the code from http://www.javaworld.com/javaworld/javatips/jw-javatip66.html to open a web browser to a specific URL. That worked great! However, I run into a problem if the URL targets a specific page, for example, "http://www.yahoo.com/news.html" would give me an problem with the shortcut problem. Any ideas how to get around that?
The command rundll32 url.dll,FileProtocolHandler http://www.yahoo.com/news/ would work fine, except anything ends with .htm or .html.
Thanks,
David

It looks like url.dll doesnt like .htm or .html files. For more info look here: http://www.jsiinc.com/SUBI/tip4100/rh4162.htm
For some reason it is confused by the 'm' character in .html which is odd considering it has no problems with .com
So if you want to keep using url.dll, do something like this:
replace ".htm" with ".ht%6D"

Middle mouse button in FF 4.0, Linux, does not open new url from clipboard

In new version FF 4.0 on Linux, middle mouse button doesn't open url (which is copy from clipboard in Linux style) without http:// prefix. It open url in format "http://www.mozilla.com" but doesn't open "www.mozilla.com". It works properly in previous versions FF.

And, wouldn't you know it, an hour after posting I found the simple solution...
Someone suggested that the Logitech RX300 mouse had a problem with mapping the middle (wheel) mouse button - try another one.
I tried 4 various mice - they all worked. The Logitech RX30x mice needs some adjustments.

Opening new tab with java/javascript/javafx?

Are there any methods that allow to open a new Tab? No tab in a TabPane, in your Browser.
Thanks in advance

Try HostServices.showDocument(uri) for a JavaFX solution, use google to find a javascript solution.

Open new URL, not working?

Using AS 2 i'm trying to open a new browser window/URL, but this code isn't working. Any suggestion? thanks
on (press) {
getURL(www.brokerschoice.com/blackvault.html);

If that code is attached to an object, then you need to place the getURL line inside the curly braces. For that line to open a new window you would use...
getURL("http://www.brokerschoice.com/blackvault.html", "_blank");

Open new url window with specific parameters

usually, one would use window.open(url,parameters)
When using air, the only option I found was
air.navigateToURL(url) and it doesn't seem to allow parameters.
Can anybody please tell me how to perform a similar action to
window.open(url,parameters) ??

i made this function, to do that in simple way
* @author cybergib15
* Crear una ventana nueva
* @param {String} html Ruta del archivo html o pagina.
* @param {Int} width Ancho de la ventana.
* @param {Int} height Alto de la ventana.
* @param {Boolean} transparent
* @param {Boolean} resizable
* @param {Boolean} maximizable
* @param {Int} left
* @param {Int} top
* @return {Object} Retorna el objeto HTMLloader.
function
nuevaVentana(html,width,height,transparent,resizable,maximizable,left,top){
var options = new air.NativeWindowInitOptions();
options.systemChrome =
air.NativeWindowSystemChrome.STANDARD;
if(transparent==true)
options.systemChrome=air.NativeWindowSystemChrome.NONE;
options.transparent = transparent;
options.resizable=resizable;
options.maximizable=maximizable;
if(left==undefined)left=0;
if(top==undefined)top=0;
var windowBounds = new air.Rectangle(left,top);
windowBounds.width=width;
windowBounds.height=height;
newHTMLLoader = air.HTMLLoader.createRootWindow(true,
options, true, windowBounds);
newHTMLLoader.load(new air.URLRequest(html));
return newHTMLLoader;
}

Open new window using java code and not in script

i need some method like sendredirect or forward . where i can make some codes so as to open a new window.
actually i am calling a jsp from one jsp file where a lot of dynamic parameters are sent. and in the second jsp i call a servlet which works to download a file to the client side. i want the file should open in new window not in the browser from where it is initiated.
else can any one say the mime type where i can open file(a xls file) in xls window and not in browser which is not needed as user needs to press the back button(present in browser)

Hi,
in your code
the following code, which is used to set the file name that is to be downloded
response.setHeader("Content-Disposition", "*inline*; filename=somename.xls" );
to be replaced by
response.setHeader("Content-Disposition", "*attachment*; filename=somename.xls" );
it will work fine try it.
