最低级的spring例子中出现的异常，求大神

最低级的spring例子中出现的错误，求大神。
自己写了一个xml，准备用于spring中，但是eclipse提示有错误。求大神赐教。错误如下描述。

applicationContent.xml内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN"
"http://www.springframework.org/dtd/spring-beans.dtd">

<beans>
<bean id="colorInk" 
class="mypackage.ColorInk" >
</bean>
<bean id="grayInk" 
class="mypackage.GrayInk" >
</bean>

<bean id="a4Paper" class="mypackage.TextPaper">
<property name="charPerLine" value="10" />
<property name="linePerPage" value="8" />
</bean>

<bean id="b5Paper" class="mypackage.TextPaper">
<property name="charPerLine" value="6" />
<property name="linePerPage" value="5" />
</bean>

<bean id="printer" class="mypackage.Printer">
<property name="ink" ref="colorInk" />
<property name="paper" ref="b5Paper" />
</bean>

</beans>

错误：can't connect to SOCKS proxy:Connection refused :connect
错误指示在这一行：class="mypackage.ColorInk" >

越过这个错误提示进行运行，则出现错误：

------解决方案--------------------------------------------------------
你没有把你引用的包部署在web服务器上
org/apache/commons/logging/LogFactory

就是这个
