The attribute required is undefined for the annotation type XmlElementRef
I tried to create an endorsed folder in JDK and include .jars needed,

We can fix the above behavior by replacing the following jars in Mule CE Runtime Folder(C:\AnypointStudio\plugins\org.mule.tooling.server.3.5.0_3.5.0.201405141856\mule\lib\opt):
我们可以通过替换Mule CE 运行时文件夹(C:\AnypointStudio\plugins\org.mule.tooling.server.3.5.0_3.5.0.201405141856\mule\lib\opt) 中的以下 jars 来修复上述行为：
jaxb-api-2.1with jaxb-api-2.2.jar
jaxb-api-2.1和jaxb-api-2.2.jar
jaxb-impl-2.1.9with jaxb-impl-2.2.7.jar
jaxb-impl-2.1.9和jaxb-impl-2.2.7.jar
jaxb-xjc-2.1.9with jaxb-xjc-2.2.7.jar
jaxb-xjc-2.1.9和jaxb-xjc-2.2.7.jar
It would be useful if Mule developers updated these packages to the newest distributions.
如果 Mule 开发人员将这些包更新到最新的发行版，那将会很有用。

The location of your endorsed jars is incorrect. It should be:
您认可的罐子的位置不正确。它应该是：
%JAVA_HOME%\jre\lib\endorsed
%JAVA_HOME%\jre\lib\endorsed
which in your case is:
在你的情况下是：
C:\Java\jdk1.7.0_55\jre\lib\endorsed
C:\Java\jdk1.7.0_55\jre\lib\endorsed
Put the jaxb jars here, remove all others and re-try.
将 jaxb 罐子放在这里，移除所有其他罐子，然后重试。

I was getting the same error message in a new project that I created in Eclipse. The solution was to:
我在 Eclipse 中创建的新项目中收到相同的错误消息。解决方案是：
1.) create a new JAXB project instead of some other project type,
2.) specify JDK7,
3.) Specify version 2.2 of JAXB

In Mule specific case, if you are stuck with JAXB2.1, you can force Apache CXF WSDL2Java to generate JAXB2.1 compliant client code
在 Mule 特定情况下，如果您坚持使用 JAXB2.1，则可以强制 Apache CXF WSDL2Java 生成符合 JAXB2.1 的客户端代码
