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：
-
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
-
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-
<dependency>
<groupId>javax.activation</groupId>
<artifactId>activation</artifactId>
<version>1.1</version>
</dependency>
<dependency>
<groupId>javax.mail</groupId>
<artifactId>mail</artifactId>
<version>1.4</version>
</dependency>
springBoot引用-
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>
