Opening new default browser from java app
Hi There,
I would like to know if there is away to execute the following in a Java app that will open a new browser window.......in other words, I don't want it to take over the already opened window - just open a new window every time.
Runtime.getRuntime().exec("rundll32 url.dll,FileProtocolHandler
www.google.co.nz");Any help with this would be greatly receievd.
There might be. However it would be done by modifying that Windows-specific command that you have in red there. As such it's nothing to do with Java. Searching in Windows-specific websites might get you somewhere.
However Firefox gives the choice (new window, new tab, or same tab in same window) to the user as a configuration option, so I wouldn't bet on getting somewhere. I don't know if IE has a similar configuration option.

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 open a web browser from java
Hi
Would anybody please help me with this. I need to open a web browser from my java app but I don't know. What method I can use?
Thanks.
Hung.You can use the Runtime class for this. It can run any command. So, you can run the .exe file of your Web browser.
The following code will run Internet Explorer (assuming iexplorer.exe is in C:\Program Files\Internet Explorer):
import java.lang.Runtime;
public class Explore{
public static void main(String[] args) {
try{
Process p = Runtime.getRuntime().exec("C:\\Program Files\\Internet Explorer\\iexplore");
}catch (Exception e) {
System.out.println("Exception: " + e); -
Problem with opening browser from Java app.
Hi guys, I'm not sure if this is the right place to post this, so please excuse me if I'm wrong. I'm trying to open an html page (it's a help file) from a Java application. I'm currently using java.awt.Desktop. browse(URI uri); which gets the job done, as long as I don't pass any parameters to the page. (e.g. http://www.site.com/site.html?param1=1). Doing that gives me an IOException. Is there a way to do this without using the JNLP API?
This is the file path copied directly from the browser's address bar:
file:///home/riaan/EMCHelp/Help.html?page=WorkFlowActivityCategory.html"{code}
Which causes the app to throw an exception, but when I change it to:
{code}file:///home/riaan/EMCHelp/Help.html{code}
it opens Help.html in the browser. That's why I thought that it might be the query that's a problem. Perhaps it's a simple issue of not escaping a character or something that I failed to see. -
Opening default Browser from embedded Flash
The Situation is this:
I have a running flash application myapp.swf (Actionscript
2), which runs on a server and requires a parameter (
http://myserver.com/myapp.swf?myparam=value).
I now want to create an AIR Wrapper for this application. So
I embed the above URL in a html-based AIR Project using the embed
tag. When I launch my new AIR Project the application is displayed,
but when I click on a link within the flash application a new AIR
window opens, displaying the respective Webpage.
But it should instead open a new tab or window in the default
Browser of the respective operating system.
I have tried the following without success:
- Attempt to create a flash-based AIR Application. The
application did not work properly since the swf file is on a server
and not within the AIR Appplication. If I download the swf-file and
put it in this directory I can't pass it the required parameter
- Trying to open a default Browser window like this:
http://snipplr.com/view/4442/adobe-air-open-new-url-with-sandbox-bridge.
I belive this only works with a flash-based AIR Application too
The best solution for me would be, if I could solve the
problem without having to alter the flash part. But, if neccessary
changing the flash part would also be an option.
I really would appreciate any comments / suggestions on this
matterI should probably add, that I am not a very experienced AIR
Developer.
quote:
So lets get this straight, you now have the content
embedded/loaded within a HTMLLOADER, right?
Probably not... I have a Html based project. Meaning that I
refer to an initial html file from my application.xml. In this html
File I embed the mentioned flash application using the following
line:
< embed height="100%" width="100%" src="
http://myserver.com/myapp.swf?myparam=value"
/>
Could I use HTMLLoader in a HTML-based AIR app?
quote:
And when the AIR APPLICATION is launched, you would want the
links that are embedded within the HTMLLOADER to open up in a
browser?
This is correct, but it should open up the default Browser
like IE or Firefox but not a new AIR window.
quote:
Are you using: navigateToURL(new URLRequest("
http://" + url), "_blank");
I am not using navigateToURL since the flash application I am
working with "does not know" that it is wrapped by an AIR
application. Therefore, it opens new URLs the way it is normally
done in a flash stand-alone application.
As I see it AIR recognises that a link is being called and
opens a new, AIR window instance.
I have seen the article about Windows Vista before, but I
would think that it is not directly related to my problem, since I
do not have to problem whether links are being opened in, for
example, Firefox or Internet Explorer but links are opened in a
build-in AIR Window.
I hope shed some light on the problem I am having... -
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,
ARthis 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!!!

How to execute Linux command from Java app.
Hi all,
Could anyone show me how to execute Linux command from Java app. For example, I have the need to execute the "ls" command from my Java app (which is running on the Linux machine), how should I write the codes?
Thanks a lot,You can use "built-in" shell commands, you just need to invoke the shell and tell it to run the command. See the -c switch in the man page for your shell. But, "ls" isn't built-in anyays.
If you use exec, you will want to set the directory with the dir argument to exec, or add it to the command or cmdarray. See the API for the variants of java.lang.Runtime.exec(). (If you're invoking it repeatedly, you can most likely modify a cmdarray more efficiently than having exec() decompose your command).
You will also definitely want to save the returned Process and read the output from it (possibly stderr too and get an exit status). See API for java.lang.Process. Here's an example
java.io.BufferedReader br =
new java.io.BufferedReader(new java.io.InputStreamReader(
Runtime.getRuntime().exec ("/sbin/ifconfig ppp0").
getInputStream()));
while ((s = br.readLine()) != null) {... -
Close parent window of Mozilla browser from Java
Hi All,
I want to open a URL in a controlled browser from java stand alone application. I was able to do this in Netscape of UNIX OS. The method followed is given below.
1. Launch a temporary HTML file which contains Javascript (to launch the URL in a controlled window). This is done using --- Runtime.getRuntime().exec() method.
2. Close the parent HTML file on 'onLoad' using Javascript. (self.close).
[ I tried window.close() & top.close() also.]
Now I need to support the same for "Mozilla" also. But mozilla just ignores the close() command of Javascript.
1. Is there any alternative way to close the parent window in Mozilla browser ?
2. Is there any way to close the parent window from java by using 'Process' class/ threads/ ??
3. Any other way???
Note : I am using the intermediate window for using Javascript. (controlling the browser properties). Since Java cannot communicate to Javascript directly, I am forced to have such an intermediate HTML file.
Thanks in advance.
surekha_Venugopal.Some more details :
Mozilla browser will close a window using window.close() command, but only if the window is opened by the script. If not it will not close it.
Here, I am opening the window from Java application. That is why closure of the window is failing.
Trying to find a solution.

I want to be able to open up a file (from an app or mobile website) to show a customer, then be able to send it to them. So add a 'Email this file to Client' link that opens up an email with file attached. Is this possible in any of the Adobe Creative Cloud Applications?
Thank you for the feature request.
Besides attaching the file to an email yourself, you can use file syncing and the Send Link feature to email a link to your customer.
File syncing is built into the Creative Cloud desktop application that you use to download and install Adobe desktop applications. Files saved to the Creative Cloud Files folder on your computer are synced up to a cloud file storage. From the Files page in a browser at https://creative.adobe.com/files you can used the Send Link feature.
The email will be sent and received more quickly since no file is attached, and your customer can download the file from the url you share. -

Actually Desktop.open only works for downloaded pages.
Instead you can use this to get the browser to download the page and display it.
Desktop.getDesktop().browse(URI.create("http://www.google.co.uk"));
First of all thanks for your reply Mr Peter__Lawrey.
