请问我怎么连接不上数据库的池?

所有代码如下


import javax.naming.*;
import javax.naming.InitialContext;
import java.util.*;
import javax.sql.DataSource;


public class CP{


public static void main(String[] argv)
{

try{
InitialContext initialcontext = new InitialContext();
DataSource datasource = (DataSource)initialcontext.lookup ( "com.jdni.datasource ");
Connection connection = datasource.getConnection(); }
catch(Exception e)
{
}

}


}


出错
E:\> javac CP.java
CP.java:16: '} ' expected
}
^
CP.java:9: cannot resolve symbol
symbol : class InitialContext
location: class CP
InitialContext initialcontext = new InitialContext();
