Opening a new URL in an existing browser window from a Java application

I've tried one of the many codes to open a new browser window and it works, but I need something else.
Is there any way to open a new URL on the same window on a Java desktop application? (Changing the URL on the current browser window without opening a new one, I mean).

You can do that by using an add-on such as:
* NewTabURL - https://addons.mozilla.org/firefox/addon/newtaburl
* New Tab Homepage - https://addons.mozilla.org/firefox/addon/new-tab-homepage
Another way of opening the home page in a new tab is to middle click on the home button in the navigation toolbar.

How to reduce CPU utilization time in Java Application

Hi,
I have created a Java Application. It is a 3-tier architecture. While running my Java application, the CPU utilization percentage shots up to 100 %. I feel that it will affect the system performance and it will hang up the system also.
If any body know the solution to reduce the CPU utilization or links, please post it.
Thanks in advance.

I know Java class file must be interpreted by VM. but
Visual Basic is also a language to be interpreted. Why
it run faster than Java? As Java running speed is
concerned, it's unwise to apply to the
enterprise-level application. Now I can't endure Java
running speed. I wander to know whether it is
associated with operating system or not.1. Java is nto interpreted in modern (since 1997 or earlier) JVM's - it is compiled into machine code as it is executed via a JIT or a Dynamic compiler (like HotSpot).
2. VB (5 and later) is also not truely interpreted - in fact it uses the same excellent native code generator used by Visual C++.
3. Java is principally used these days for enterprise server-based systems where it performs extremely well - or extremely poorly as does C++ in the hands of people who don't know how to use it.
4. Different JVM's (and in some cases the same JVM hosted on different OS's) perform at different speeds - your mileage will vary. The OS has little influence on the computational speed of java but can highly influence its network, disk and graphics performance, as does hardware configuration (local console versus X terminal - Swing sucks on X Term).

That'll pop up another consoleI'm under the impression that the console window he is seeing is the one which cmd.exe opens when it is executing the batch file. And that batch file won't return until the java process has completed because he didn't start it in the background to let the batch file continue and terminate.
So I don't think just simply substituting java with javaw will do much good either. Still think he needs a "start" command in that batch file.
So now he can try:
start java -jar ...
or
start javaw -jar ...Fair point

Creating a Windows installer for Java applications

Hello, I have a question about deployment:
I have a pure Java desktop application. Obviously, it's in the form of a JAR file. I want to sell this to users who are "clueless" about Java, so I need to wrap it up in an installer file that does the following:
1. Detects if there is a JRE on the system. If there isn't, send the user over to java.com to grab one.
2. Once a JRE is installed, then it should install itself so that there are menu entries on the Start menu, icons, all that kind of stuff.
3. Ideally it would look like it's just a plain old .exe file so users don't even need to be concerned with JARs, etc.
I found these two open source apps that can wrap a JAR into an EXE:
http://jsmooth.sourceforge.net/
http://launch4j.sourceforge.net/
Both of them look great. They take a JAR and make it into a smart .EXE that knows how to find a JRE and provides reasonable feedback if no suitable JRE is found. launch4j can also display a splash screen, which sounds trivial, but is actually quite important for the user experience. That's great. But the next step is to wrap this EXE into a real installer that sets up menus and icons. Any suggestions on this?
Thanks

How to open browser window from standalone Java Application???

Is it possible to start Internet Explorer from non-applet application?

Something like that could maybe help:
Runtime.getRuntime.exec("iexplore http://www.google.com");
but it's not platform independent + I couldn't let it work in that way. It only worked with Runtime.getRuntime.exec("c:\\windows\\....\\iexplore.exe http://www.google.com");
But it's surely not platform independent.
So the answer is in fact 'I don't know'.
And if you ask why am I writing all that then, the answer is 'I don't know' too.

Closing the IE browser thro' Java application

Hi,
I have a requirement wherein I have to close the applications launched like (Internet exploer window) thro my java application.
Can anyone help me on this?
I tried using Runtime class Process.destroy( ) method. But still not able to find the exact one.
Thanks.

maybe this is because the code did not create the process directly, ao destory() method doesn't work as expected.
Process ps = Runtime.getRuntime().exec("rundll32 url.dll,FileProtocolHandler " + "my website open here")
maybe ps not reference to the process create by rundll32
then there is no way to close a browser directly from java application?

Windows under a Java programm

Hello,
how can I implement Windows of instructions with a Java program?
A program steer, without being even active. Separate only
over a Javaprogramm. How can I Windows Shut down??
Thanks

i will Windows from a Java application Shut down.You want your Java program to tell Windows to shut down?
(Damn Germans and their word order.)
You cannot do that in pure java. You have to write native code for it. So you need to a) read up on JNI to find out how to include native code in your java program, and b) go to a Windows-specific place and find out how to tell Windows to shut down, and c) sew it together. (Sorry, I can't help you with any more details.

How to start a java application by double clicking just like windows gui?

Hi,
I want to open the user-defined file in my java application. The way is like the notepad in windows:1.double click the file name 2.the file is opened in the java application 3.if this file has opened at the same time ,then the last opened will be read-only.
Could you tell me how to carry it out ? Thank you
from Maria

!!! Please give me a help! i am thirsty for itSo, to get this straight, you have a Java application in a jar. For some reason, you do not execute this directly. Are you aware that you can execute a jar directly without the need to write a C++ exe to do it?
Anyway, for some reason, instead you have a C++ application which launches the JVM with your jar main class.
Well, you want to do two things. First of all, on Windows level, you need to associate the file type of your user file with your application. Note that they have to have a specific file extension that you choose. To associate the file type with an executable, you open a windows explorer, go to View, Folder Options, File Types and add an entry for your file type and specify it to open with your application. If you do not know how to do this, google for "windows associate file type with program executable" or something alike.
Now, if you double-click one of your user files, the associated exe will open, and it will receive the file name as a command line argument. In your C++ application, you will need to pass this argument, a file name, to the Java application where you launch it.
