error and solve
1、缺少对应的jar包
出错信息：
Multiple markers at this line
- The type org.springframework.beans.factory.Aware cannot be resolved. It is indirectly
referenced from required .class files
- The hierarchy of the type SetSurveyAction is inconsistent
解决办法：
原因是缺少对应的包，导入包就行了
2、option是mysql的关键字
出错信息：
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException:
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'option) values (3, 'é?????hb', 0)' at line 1
解决办法：
option是mysql的关键字
将SurveyChild表中的option字段改一下就ok啦
3、需要mail.jar和activation.jar
出错信息：
- Unable to find required classes (javax.activation.DataHandler and javax.mail.internet.MimeMultipart). Attachment support is disabled.

解决办法：
错误原因：
需要mail.jar和activation.jar。
Solution:
Web Services Required Jars Download Instructions http://www.eclipse.org/webtools/wst/components/ws/download_instructions_for_jars.html
解决办法：
1) 下载javamail和jaf，解压出mail.jar和activation.jarhttp://java.sun.com/products/javamail/downloads/index.html
http://java.sun.com/products/javabeans/glasgow/jaf.html#download
或者我提供了一个rar包：包含mail.jar action.jar
download：mail.jar and activation.jar
2) 把mail.jar和activation.jar放到%AXIS_HOME%/WEB-INF/lib目录下
3) 将.jar文件添加到%CLASSPATH%
说明：
这个是可以忽略的。不过以后构建web services都要用到的，还是添加上的好。

This is a warning message that can safely be ignored. It is displayed when Axis has been deployed without an optional JAR. An optional JAR is one that allows Axis to support a particular piece of functionalty but is not required for general use. Please refer to the Axis documentation for more details.备注：
