When i am tryin to connect my java program to MySql database...it is showing following error:

Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial

...............................................
See the following code and let me know if anything is incomplete or any error

Context initCtx =

new InitialContext();
Context envCtx = (Context) initCtx.lookup("java:comp/env");
DataSource ds = (DataSource) envCtx.lookup("jdbc/Authentication");
conn = ds.getConnection();

System.out.println ("Database connection established");

I'm not sure with what you're doing, but you need to have something like this:

PHP Code:

  private String bnDbDriver = "org.gjt.mm.mysql.Driver"; //Driver for your database
private String bnDbId = "jdbc:mysql://localhost/dbname"; //database name
private String bnDbUser = "username"; // your username
private String bnDbPassword = "password" //your password

//******************
//GET THE CONNECTION
//******************
Class.forName(bnDbDriver);
Connection myConnection = DriverManager.getConnection(bnDbId, bnDbUser, bnDbPassword);

//YOU SQL STATEMENT
Statement myStatement = myConnection.createStatement();
String sqlQuery = "YOR SQL STATEMENT";
myStatement.executeQuery(sqlQuery);
