classformaterror

I am trying to send an email from my application when a user logs in for the first time. The email consists of a activation code. Update: I downloaded the latest javamail API and also the latest JAF (JavaBeans Activation Framework) and it does not compile due to imports being unknown symbols. How do I import from the javax package? Here is the code that I got so far: import java.util.ArrayList; import javax.mail.Message; import javax.mail.MessagingException; import javax.mail.Session; import javax.mail.Transport; import javax.mail.internet.AddressException; import javax.mail.internet

I am getting a strange ClassFormatError when using the javaMail api to send email on my spring mvc web app. Below is my mail-cfg.xml <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/mvc http://www.springframework
