数据库连接池！请各位帮忙！

import javax.servlet.http.HttpServlet;
import javax.servlet.ServletConfig;
import javax.servlet.ServletException;

import java.sql.SQLException;
import java.sql.Connection;
import javax.sql.DataSource;
import org.apache.struts.util.*;
import org.apache.struts.util.GenericDataSource;
import java.sql.*;
public class DBInitServlet extends HttpServlet {

public void init(ServletConfig config) throws ServletException {
super.init(config);
try {

GenericDataSource ds = new GenericDataSource();
ds.setDriverClass(getInitParameter("driverClass"));
ds.setUrl(getInitParameter("jdbcurl"));
ds.setMinCount(Integer.parseInt(getInitParameter("minCount")));
ds.setMaxCount(Integer.parseInt(getInitParameter("maxCount")));
ds.setAutoCommit(false);
ds.open();
ConnectionPool.init(ds);

} catch (SQLException e) {
e.printStackTrace();
throw new ServletException("Unable to open datasource.");
}

}

}
编译未通过
GenericDataSource ds = new GenericDataSource();这个有问题
