前天在项目中实现了用SSH整合实现邮件发送
package cn.xdd.util;
/**
* 简单验证码生成类
*/
import java.util.Random;
public class RandomCheckCode {
public static String getCheckCode(){
String checkCode[]={"A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q"
,"R","S","T","U","V","W","X","Y","Z","a","b","c","d","e","f","g","h","i","j","k","l","m",
"n","o","p","q","r","s","t","u","v","w","x","y","z","0","1","2","3","4","5","6","7","8","9"};
Random random=new Random();
StringBuffer sbf=new StringBuffer();
for(int i=0;i<6;i++){
sbf.append(checkCode[random.nextInt(62)]);
}
return sbf.toString();
}
}

}
}
直接测试时没有问题,但在发布到Tomcat服务器时就有问题了,
15:43:55,608 ERROR ContextLoader:211 - Context initialization failed
org.springframework.beans.factory.BeanDefinitionStoreException: Error registering bean with name 'javaMailSender' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Class that bean class [org.springframework.mail.javamail.JavaMailSenderImpl] depends on not found; nested exception is java.lang.NoClassDefFoundError: javax/mail/MessagingException
java.lang.NoClassDefFoundError: javax/mail/MessagingException
搞了很久都不明白是什么回事,因为在测试时都没有问题,而且提示中的包在项目里都有.最后通过网上搜索把问题解决了，
原来在使用Spring这样的框架的一些丰富功能时，都要在完整的J2EE容器下运行，因为Spring只不过提供J2EE容器功能的又一种调用方式罢了，所以把j2ee中的activation.jar,和mail.jar（（E:\Myeclipse\Common\plugins\com.genuitec.eclipse.j2eedt.core_10.5.0.me201207171805\data\libraryset\1.4））包复制到Tomcat中的common/lib目录下就发布成功了．
