问题

抱歉，由于您要求只返回翻译好的部分，以下是您提供的内容的翻译：

我正在尝试一个使用xml-to-object-transformer>转换器在Mule3中将实际XML转换为Java对象的用例，而没有使用DW。我最终遇到了一个奇怪的问题，请检查是否有人可以帮助。

为了实现这个目标，

1. 使用XJC JAXB API生成了一个JAXB类。
2. 将该类设置为转换器中的别名类，以验证数据类型。
3. 使用上述别名进行xml-to-object-transformer转换。

I am trying a usecase that the actual XML to be transformed as Java Object by using xml-to-object-transformer&gt; transformer in Mule3., no DW.  I ended up with a strange issue and pls chk if anyone can help.

To do that,

 1. Generated a JAXB class using XJC JAXB API  
 2. Setting that class as alias class in the transformer to validate the data types
 3. Do the xml-to-object-transformer with the above alias

**Code snippet of Mule**

    &lt;mulexml:xml-to-object-transformer driverClass=&quot;com.thoughtworks.xstream.io.xml.Xpp3Driver&quot; doc:name=&quot;XML to Object&quot;&gt;
    	&lt;mulexml:alias class=&quot;com.test.jaxb.model.Root&quot; name=&quot;root&quot;  /&gt;
    &lt;/mulexml:xml-to-object-transformer&gt;

似乎问题出在您正在使用&lt;mulexml:xml-to-object-transformer&gt;转换器，它不知道如何处理JAXB处理。您应该尝试使用[JAXB转换器][1]。

对于旧版本的Mule，有一个类似的先前答案：https://stackoverflow.com/a/20243878/721855

<summary>英文:</summary>

It looks like the problem is that you are using the &lt;mulexml:xml-to-object-transformer&gt; transformer, which doesn&#39;t know how to handle JAXB processing. You should try instead the [JAXB transformers][1].

There is a previous similar answer for an older version of Mule: https://stackoverflow.com/a/20243878/721855
