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.

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.

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!!!

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 create windows users and groups from Java

Hi,
Can any one please tell me, which Package/API will helps to create windows users and groups from Java.
Thanks,
M.Prem.

You can't do it with pure Java, and it's not in the core API. You'd have to write a native function to do it, using whatever API Windows provides, and then call it with JNI. Or look for a third party native-based Java library that already does that.

Controlling a browser from java

hello experts,
i want to open an web dynpro URL in a browser and navigate through the URL , like putting values in the input box and click the buttons from java code .
Actually it is exactly like an automated test tool in java to navigate and render the given web dynpro URL with the test data given.
its very please help.
Regards,
Karthik

Hello Karthik,
I'm using Selenium to do something similar. You can find more information at http://seleniumhq.org/
The documentation can be found at http://seleniumhq.org/documentation/ and you can find a tutorial implementation for Java at http://seleniumhq.org/documentation/tutorials/
You can use a new Java Project to start using Selenium, just in case you feel confused.
I've been using Selenium for some time now, you will learn some tricks during the way. And you'd probably take a look on waitForCondition function, since you'd need some calls in order to wait for webdynpro ajax requests to populate tables (before doing your assertions).
Hope it helps.
Regards,
Daniel

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);

Call Windows COM/DCOM objects from Java on Linux

Hello, is it possible to call COM/DCOM objects running on Windows from Java on Linux machine? Thank you.

I don't know anything about it but it looks like EZ JCom in conjunction with the included Remote Access Service does what you're after. It's not free though.

How to control browser from java program?

I want to retrieve the url currently loaded in my default browser. How to achieve this task using java program? I dont know how to access browser using java.

Peter__Lawrey wrote:
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.
I want to just retrieve the urls loaded in the default webbrowser, not the content of the url or the task of opening the default browser with the specific url.

Calling Window's Dll Functions from Java

Hello Audience,
Is there a way to call Win32/64 based Dynamic-Link-Library functions from Java?
Thanks,
GenKabuki

Yes.
In general, if you are trying to call functions in an existing dll, you will have to write a "wrapper" dll that meets the java jni interface requires. There are tools around wich purport to generate these for you. Do a google serach; among other tools, you should turn up JACE.

Well, how is a browser normally invoked on Solaris? And have a look at JDIC, maybe it helps you.

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.
