Answer / dsr

contex ic = new InitialContext();
DataSource sd = (datasource)ic.lookup("poolname");
Connection con = ds.getConnection();

Answer / ravikiran(aptech mumbai)

datasource.
getDatasource.getconnection();

Answer / qim2010

An application simply uses the DataSource.getConnection
method to get the pooled connection and uses it the same way
it uses any Connection object.

The classes and interfaces used for connection pooling are:

ConnectionPoolDataSource
PooledConnection
ConnectionEvent
ConnectionEventListener

The connection pool manager, a facility in the middle tier
of a three-tier architecture, uses these classes and
interfaces behind the scenes. When a
ConnectionPoolDataSource object is called on to create a
PooledConnection object, the connection pool manager will
register as a ConnectionEventListener object with the new
PooledConnection object. When the connection is closed or
there is an error, the connection pool manager (being a
listener) gets a notification that includes a
ConnectionEvent object.

Answer / therathna

first to get the Context object by using given bellow

Context ic=new InitialContext();

And get DataSource object by using ic.lookup(conncetionpool
name)



your question is not proper way


DataSource Class & getConnection method is used
connection pool

1 Answers   TCS,

3.2 Consider the following class: public class Point { protected int x, y; public Point(int xx, int yy) { x = xx; y = yy; } public Point() { this(0, 0); } public int getx() { return x; } public int gety() { return y; } public String toString() { return "("+x+", "+y+")"; } } Say you wanted to define a rectangle class that stored its top left corner and its height and width as fields. 3.2.1 Why would it be wrong to make Rectangle inherit from Point (where in fact it would inherit the x and y coordinates for its top left corner and you could just add the height and width as additional fields)? (1) 8 Now consider the following skeleton of the Rectangle class: public class Rectangle { private Point topLeft; private int height, width; public Rectangle(Point tl, int h, int w) { topLeft = tl; height = h; width = w; } public Rectangle() { this(new Point(), 0, 0); } // methods come here } 3.2.2 Explain the no-argument constructor of the Rectangle class given above. 3.2.3 Write methods for the Rectangle class to do the following: • a toString() method that returns a string of the format "top left = (x, y); height = h; width = w " where x, y, h and w are the appropriate integer values. • an above() method that tests whether one rectangle is completely above another (i.e. all y values of the one rectangle are greater than all y values of the other). For example, with the following declarations Rectangle r1 = new Rectangle(); Rectangle r2 = new Rectangle(new Point(2,2), 1, 4); the expression r2.above(r1) should give true, and r2.above (r2) should give false. (You can assume that the height of a rectangle is never negative.) (2) (5)
