[dr_pompeii]

Hello guys
i need really your help, my boss have a gun and .... i want to live,
i cant send a simple email
this is my xml configuration

<beans>
<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl"> 
   <property name="host"> 
   	<value>mail.yahoo.com</value>
    </property>
    <property name="username" >
   	<value>usernamesenderyahoo</value> <!-- same result if i write with @yahoo.com-->
    </property>
    <property name="password">
	 <value>passwordsenderyahoo</value>
    </property>		    	    
    <property name="javaMailProperties">
        <props>
	  <prop key="mail.smtp.auth">true</prop>
        </props>
    </property>
</bean>
		
<bean id="messageSender" class="com.test.ComplexMessageSender" >
   <property name="javaMailSender">
	<ref local="mailSender"/>
   </property>
   <property name="to">
	<value>emailaddressdestination@hotmail.com</value>
   </property>
   <property name="from">
	<value>usernamesenderyahoo@yahoo.com</value>
   </property>
   <property name="subject">
	<value>Spring mail</value>
   </property>						
</bean>			  
</beans>

when i start up the tomcat 5.5.27, by "ant" i execute a java class that call a bean

ComplexMessageSender plex = (ComplexMessageSender) ctx.getBean("messageSender");			
plex.sendMessage();

so after almost 3-5 minutes i recieve this prize
