我把數據庫的連結參數寫在 web.xml 中,如何用 javabean 取得,不是用 servlet 
請眾大俠幫忙 .

我的用法
配置文件：/WEB-INF/classes/config.conf

serverURL=jdbc:mysql://localhost:3306/yonghang
userName=root2
passWord=123456
conMin=5
conMax=30
conTimeOut=3
driver=org.gjt.mm.mysql.Driver
LogFile=c:\log.log
ErrLogFile=c:\logerr.log
sysLog=c:\syslog.log

读写的类1：PropManager.java (/WEB-INF/classes/PropManager.class)

import java.io.*;
import java.util.*;

public class PropManager {

private Properties Props;
private String path="/config.conf";
        public PropManager(String strConfig)
        {
            if(strConfig==null || strConfig.equals(""))
                init(path);
            else
                path=strConfig;
                init(strConfig);
        }
        public PropManager()
        {
            init(path);
        }
public String getProperty(String name)
{
try
{
String property=Props.getProperty(name);
if(property==null)
{
property="NULL";
}
return property;
}catch(Exception e)
{
System.err.println("CONFIG FILE ERROR! ");
return null;
}
}
private void init(String paths)
{
InputStream in=null;
try
{
//System.out.println(paths);
                        in=getClass().getResourceAsStream(paths);
                        //System.out.println(in);
}catch(Exception e)
{
System.out.println(paths);
                        System.err.println("Config.File ERROR! NO FOUND!");
}
try
{
Props=new Properties();
Props.load(in);
System.err.println("PropManager Load Successed!");
}catch(IOException e)
{
System.err.println("FileInputStream in ERROR!");
}
}
}


读写的类2：PropertyManager.java (/WEB-INF/classes/PropertyManager.class)

import PropManager;

public class PropertyManager
{
private static PropertyManager propertyManager=null;
        private static PropManager propManager=null;
        private static String path="/config.conf";
private static boolean staus=false;
public PropertyManager()
{
init();
}
public static String getProperty(String name)
{
                checkStaus();
                try
{
                    return propManager.getProperty(name);
}catch(Exception e)
{
                    System.out.println(" DBPool.PropertyManager.getProperty() ERROR!");
                    return null;
}
}
//内部方法
        private static void checkStaus()
        {
            if(!staus || propertyManager==null || propManager==null)
            {
                propertyManager=new PropertyManager();
            }
        }
private void init()
{
try
{
propManager=new PropManager(path);
System.err.println("PropertyManager Init Successed!");
staus=true;
}catch(Exception e)
{
System.err.println("PropManager in ERROR!");
                        staus=false;
}
}
        public static void setPath(String path_)
        {
            path=path_;
        }
}


在JSP或SERVLET中使用
PropertyManager.getProperty("serverURL");
PropertyManager.getProperty("userName");
PropertyManager.getProperty("passWord");
来得到相关的参数
