Hi All

how can i deploy a Datasource object? i am using JBoss 3.0.4.

when i am using the following code i am getting a null exception when i am trying to get a connection object from the DataSource object. So could anyone tell what is the problem



import javax.sql.*;
import java.io.*;
import javax.naming.*;
import java.sql.*;

public class ConnectionPoolTest implements Serializable
{
public ConnectionPoolTest()
{
try
{
Context context = new InitialContext();
PooledDataSource ds = new PooledDataSource();
ds.setDatabaseName("mydirectoffice");
ds.setServerName("localhost");
ds.setPassword("");
ds.setUser("");
ds.getConnection().close();
}
catch(Exception e)
{
System.out.println(e.toString());
}
}


class PooledDataSource implements DataSource, Serializable
{
private Connection connection = null;
private PrintWriter printWriter = null;
private int timeOut = 10;
private String user = "";
private String password = "";
private String databaseName = "";
private String serverName = "";
public Connection getConnection()
{
return connection;
}

public String getUser()
{
return user;
}

public void setUser(String user)
{
this.user = user;
}

public String getPassword()
{
return password;
}

public void setPassword(String password)
{
this.password = password;
}

public String getDatabaseName()
{
return databaseName;
}

public void setDatabaseName(String databaseName)
{
this.databaseName = databaseName;
}

public String getServerName()
{
return serverName;
}

public void setServerName(String serverName)
{
this.serverName = serverName;
}

public Connection getConnection(String userName, String password)
{
return connection;
}

public int getLoginTimeout()
{
return timeOut;
}

public void setLoginTimeout(int timeOut)
{
this.timeOut = timeOut;
}

public PrintWriter getLogWriter()
{
return printWriter;
}

public void setLogWriter(PrintWriter printWriter)
{
this.printWriter = printWriter;
}
}
}
