import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.sql.*;
import java.sql.*;
import java.io.*;
import javax.sql.DataSource;
import javax.naming.*;
public class SrvOne extends HttpServlet {
/**
* Constructor of the object.
*/
private DataSource ds=null;
public SrvOne() {
super();
}
/**
* Destruction of the servlet.
*/
public void destroy() {
super.destroy(); // Just puts "destroy" string in log
// Put your code here
System.out.println("================destroy ---getting datasource");
ds=null;
}
public void Service(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html");
PrintWriter out = response.getWriter();
System.out.println("================service ---==================");
try{
Connection conn=null;
conn=ds.getConnection();
System.out.println("================got connection from connection
pool============");
Statement stmt=conn.createStatement();
ResultSet rs=stmt.executeQuery("select * from emp");
while(rs.next()){
System.out.println("================"+rs.getString(2));
}
conn.close();
System.out.println("==============got back from connection pool==");
}catch(Exception e){
System.out.println("============"+e.getMessage());
}
}
public void init() throws ServletException {
System.out.println("================init ---getting datasource");
try{
InitialContext ic=new InitialContext();
ds=(DataSource)ic.lookup("java:comp/OracleDS");
System.out.println("========got datasource======"+ds.getClass());
}catch(Exception e){
System.out.println("================init ---failed during getting
datasource"+e);
}
// Put your code here
}
}
and i copied oracle-ds.xml in the directory...and i m getting error like
