Run a programme by java application

You may have encountered situations where you wish to run a programme say Web Browser (FireFox) from your Java programme.
It is very simple
  • Find the location of the actual executable of the programme.
  • As in the case of FireFox Web Browser, the actual executable file is placed at C:\Program Files\Mozilla Firefox\firefox.exe
  • You can use the following code to run it from your Java application
  • Runtime runtime = Runtime.getRuntime();
    runtime.exec("K:/Program Files/Mozilla Firefox/firefox.exe");
  • (YOU MUST USE A TRY CATCH BLOCK. Just excluded them for clarity)
  • ENJOY programming :-)
Here is a great tip if you wish to launch the native applications for specific tasks such as sending a mail, opening the native web browser.

public static void main(String[] args) {
Desktop dt = Desktop.getDesktop();
try {
try {
dt.browse(new URI("http://yahoo.com"));
} catch (URISyntaxException ex) {
Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
}
} catch (IOException ex) {
Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
}
}

instead of using string "K:/Program Files"/Mozilla Firefof/firefox.exe"
it is better to use File.seperator.
However in this case, it is only intended to work with Windows XP.
(Because the directory structure exists in XP)

But suppose if you are using similar scenario to open a picture placed at ./images/pic.jpg say. Then it's better to use File.seperator as the application would work in both Windows and Linux.
Since Windows and Linux use different slash notations, File.seperator first looks at what the OS is and then replaces the relevant path seperator.

Encrypt and Decrypt Images Using Java

Hi, Most of you would find it useful to Encrypt a special picture of yours such that only you can view it. By using JCE(Java Cryptography Extension) classes, this becomes very simple. As I have already done before using Java to encrypt a String is very simple. If you are new to this, please read the article which I had already posted named "Java Encryption and Decryption" at "http://ruchiram4.blogspot.com/2009/04/java-encryption-and-decryption.html" Also, you need to have a basic understanding of Java IO. If you are new, it is better to read the Sun Java tutorial on IO. Before we move on, lets recall the basic steps in Encrypting plaintext. 1. Creating an instance of "Cipher" object and setting the mode of Encryption (Eg: AES, DES) 2. Generating a key by using a KeyGenerator object. 3. Setting the mode of Cipher operation on the Cipher object. As we intent to Encrypt, we simply set it by setting a property of Cipher object by calling its "init"

Build your own Network sniffer

Image
Recently, I ve been developing a tool to monitor the Network Traffic as an assignment. Here, I wish to share my experience with all of you who are interested in building your own Sniffer. Prerequisites : Java Programming capability, Knowledge on OOP(Object Oriented Programming) basics My Environment: I used the libraries specified for Java which is widely available. I ran my application on Windows XP only. But the libraries can be easily integrated with Linux based systems. I used NetBeans 6.1 version for development activities. But any other java IDE would do In setting up the environment, first you need to download Jpcap jar found at http://sourceforge.net/projects/jpcap Once you download this, you have to add this to your NetBeans project. It can be done as follows. After adding the Jar file to the project, you need to download the WinPCap driver. It can be easily downloaded from http://www.winpcap.org/ It is required to get low level networking access regarding packets. As for

ASP Response.Write newline

Hi, all of you who have used ASP may have encountered situations where you require to write a text output to the screen. It can be easily done by using Response.Write("Hello world"); However, if you wish to append some more text to a newline, it would not work in the following ways. Response.Write("Hello world \n"); Response.Write("Good day."); The output of the above lines would be Hello world Good day. and NOT Hello world Good day. In order to overcome this, you can very simple place an html break tag inside the code. Response.Write("Hello world"); Response.Write("<br/>"); Response.Write("Good day."); The output would be the following. Hello world Good day. Cheers !!!
