Drawing Chess Game Board in Java - Source Code

Source code for Chess Game Board in Java :

public class ChessGUI extends JFrame {
    private Board board;
    private ChessGUI() {
        board = new Board();
        setLayout(new FlowLayout());
        add(board);
        setDefaultCloseOperation(EXIT_ON_CLOSE);
        setVisible(true);
        pack();
    }

java read content of web page

The following example use easier method to read String from InputStream in Java. It uses java.util.Scanner. It will be easy/efficient to read shorter content by using this method.
Reading content of web URL:

System.out.println("Google\n" + new Scanner(new URL("http://google.com").openStream())
                                                    .useDelimiter("\\A").next());

Reading a text file :

System.out.println("TextFile\n"+new Scanner(new File("inputFile.txt"))
                                                    .useDelimiter("\\A").next());

The regex "\\A" here matches the beginning of input source. Scanner can work not only with an InputStream source, but with  anything that implements the new (JDK version >= 1.5) java.lang.Readable interface.

Deploying .war file to Apache Tomcat Server : Working way

Here i am going to describe the [MANUAL]working way to deploy your .war(web application archive) file to the Apache Tomcat Server.
Suppose you have your web application's war file ,say MyProject.war exported from Eclipse Netbeans or similar IDE.
Steps:
1.Copy this .war file to webapps folder TOMCAT_HOME directory e.g, C:\apache-tomcat\webapps\
2.Restart the server, >> run the startup.bat in folder C:\apache-tomcat\bin
3.If the error message such as
     JAVA_HOME not defined or CATALINA_HOME not defined
     Then follow these steps to setup these environment variables:

• Right-click the My Computer icon on your desktop and select 'Properties'.
• Click the 'Advanced' tab (Windows XP), click on Advance System Settings on Windows7.
  
• Click the 'Environment Variables' button.
• Under 'System Variables', click 'New'.
• Enter the variable name as JAVA_HOME.
• Enter the variable value as the installation path for the Java Development Kit. eg. C:\Program Files (x86)\Java\jdk1.6.0_20
• Repeat the process for CATALINA_HOME variable and enter installation path for Tomcat Server, eg. C:\apache-tomcat\webapps\
• Click 'OK'.
• Click 'Apply Changes'.
• Restart the Server >> run the startup.bat in folder C:\apache-tomcat\bin

4.Launch http://localhost:[PORT]/MyProject/ on the browser, (port number might be 8080 or 8400). And Make sure the work offline option is not checked.
5.If everything is ok, the Home page of your app will be loaded into browser
6.Enjoy :)

hibernate show sql & parameter to console

You need to configure it 2 places :

1) Configuration in log4j logger : add following lines in - log4j.properties file  :

log4j.logger.org.hibernate.SQL=DEBUG
log4j.logger.org.hibernate.type=TRACE

The first is equivalent to hibernate.show_sql=true, the second prints the bound parameters among other things.

2)Configuration in hibernate.cfg.xml :

<property name="show_sql">true</property>

TO Show Formatted SQL :<property name="format_sql">true</property>

java escape html string - code

1) StringEscapeUtils from Apache Commons Lang:

import static org.apache.commons.lang.StringEscapeUtils.escapeHtml;
// ...
String source = "The less than sign (<) and ampersand (&) must be escaped before using them in HTML";
String escaped = escapeHtml(source);

OR 

2) Use Spring's HtmlUtils.htmlEscape(String input) method.

    }
}

void printElements(int *array,int length) //print array elements
{
    int i=0;
    for(i=0;i<10;i++)
        cout<<array[i]<<endl;
}
void main()
{

    int a[]={9,6,5,23,2,6,2,7,1,8};   // array to sort 
    selectionSort(a,10);                 //call to selection sort  
    printElements(a,10);               // print elements 
}

Text Prompted Remote Speaker Authentication : Joint Speech and Speaker Recognition/Verification System :: Major Project ::: Introduction

Biometrics is, in the simplest definition, something you are. It is a physical characteristic unique to each individual such as fingerprint, retina, iris, speech. Biometrics has a very useful application in security; it can be used to authenticate a person’s identity and control access to a restricted area, based on the premise that the set of these physical characteristics can be used to uniquely identify individuals.

Speech signal conveys two important types of information, the primarily the speech content and on the secondary level, the speaker identity. Speech recognizers aim to extract the lexical information from the speech signal independently of the speaker by reducing the inter-speaker variability. On the other hand, speaker recognition is concerned with extracting the identity of the person speaking the utterance. So both speech recognition and speaker recognition system is possible from same voice input.

Desired Output of the Combined System

Text Prompted Remote Speaker Authentication is a voice biometric system that authenticates a user before permitting the user to log into a system on the basis of the user’s input voice. It is a web application. Voice signal acquisition and feature extraction is done on the client. Training and Authentication task based on the voice feature obtained from client side is done on Server. The authentication task is based on text-prompted version of speaker recognition, which incorporates both speaker recognition and speech recognition. This joint implementation of speech and speaker recognition includes text-independent speaker recognition and speaker-independent speech recognition. Speaker Recognition verifies whether the speaker is claimed one or not while Speech Recognition verifies whether or not spoken word matches the prompted word.
