package jsf;
import java.io.IOException;
import java.io.InputStream;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.util.HashMap;
import javax.faces.context.FacesContext;
import javax.faces.event.ActionEvent;
import javax.servlet.ServletOutputStream;
import javax.servlet.http.HttpServletResponse;
import com.mysql.jdbc.Driver;
import net.sf.jasperreports.engine.JRException;
import net.sf.jasperreports.engine.JasperRunManager;
public class ReportGenerator
{
@SuppressWarnings("rawtypes")
public void generateReport(ActionEvent actionEvent)
throws ClassNotFoundException, SQLException, IOException,
JRException
{
//
String url = "jdbc:mysql://localhost/restaurants";
String login = "root";
String password ="";
Connection connection = null;
//
//Connection connection;
FacesContext facesContext = FacesContext.getCurrentInstance();
HttpServletResponse response = (HttpServletResponse)
facesContext.getExternalContext().getResponse();
InputStream reportStream = facesContext.getExternalContext().getResourceAsStream("/reports/DbReport.jasper");
ServletOutputStream servletOutputStream = response
.getOutputStream();
//Class.forName("com.mysql.jdbc.Driver");
//connection = DriverManager.getConnection(
//"jdbc:mysql://localhost:3306/restaurants?" +
//"user=root&password= ");
//
Driver monDriver = new com.mysql.jdbc.Driver();
DriverManager.registerDriver(monDriver);
connection = DriverManager.getConnection(url, login, password);
//
facesContext.responseComplete();
response.setContentType("application/pdf");
JasperRunManager.runReportToPdfStream(reportStream,
servletOutputStream, new HashMap(), connection);
connection.close();
servletOutputStream.flush();
servletOutputStream.close();
}
}
