在调试Axis1.4访问WebService服务时，出现以下警告：

警告: Unable to find required classes (javax.activation.DataHandler and javax.mail.internet.MimeMultipart). Attachment support is disabled.

错误原因：
需要mail.jar和activation.jar。

eclipse3.6\plugins下就有这两个jar包

javax.activation_1.1.0.jar

javax.mail_1.4.0.jar

解决办法：

1. 下载javamail和jaf，解压出mail.jar和activation.jar
   javamail

   http://www.oracle.com/technetwork/java/index-138643.html

   jaf：JavaBeans Activation Framework

   http://www.oracle.com/technetwork/java/javase/downloads/index-135046.html#download

2. 引用jar包
   如：

gradle引用-

 [group: 'javax.activation',name: 'activation',version: '1.1'],
 [group: 'javax.mail',name: 'mail',version: '1.4']

mavn引用-

 javax.activation
 activation
 1.1


 javax.mail
 mail
 1.4

springBoot引用-

   org.springframework.boot
   spring-boot-starter-mail
