參考代碼：

package org;

import java.io.File;
import java.net.URL;
import java.net.URLClassLoader;
import java.sql.Connection;
import java.sql.Driver;
import java.util.Properties;

public class Test
{
    public static void main(String[] args) throws Exception
    {
        File file = new File("/root/workspace/RPT2.9SP1/WebContent/WEB-INF/lib/ojdbc14.jar");
        URLClassLoader loader = new URLClassLoader(new URL[]{ file.toURI().toURL() });
        //URLClassLoader loader = new URLClassLoader(new URL[]{file.toURI().toURL()}, getClass().getClassLoader())
        Class clazz = loader.loadClass("oracle.jdbc.driver.OracleDriver");
        Driver driver = (Driver) clazz.newInstance();
        Properties p = new Properties();
        p.put("user", "newrpt_plt");
        p.put("password", "newrpt_plt");
        Connection con = driver.connect("jdbc:oracle:thin:@10.0.1.204:1521:lgdnew", p);
        System.out.println(con);
    }
