我有一個jaxb代碼，它曾經在java 6中工作，但在更新到java 7之後，它生成的xml文件有所不同。jaxb差異bwteen java 7和java 6
Java 6中，文件看起來像這樣：
<ns2:recommendation>
<id>4</id>
<type>ARTICLE</type>
<name>Application-4</name>
<description>Great app called Application-4</description>
<publisher>Medio</publisher>
<category>Productivity</category>
<updated>01062001</updated>
<rating>4.0</rating>
<price>.99</price>
<currency>USD</currency>
<iconURI>http://medio.com</iconURI>
<downloadURI>http://medio.com</downloadURI>
<ns2:extensions>
<ns2:extension ns2:key="Sample">

</ns2:extension>
</ns2:extensions>

在Java 7，它是：
<ma:recommendation>
<id>3</id>
<type>ARTICLE</type>
<name>Application-3</name>
<description>Great app called Application-3</description>

所不同的是擴展標記，它映射到沒有按一個Java代碼不會改變。任何人都知道如何解決它？爲擴展
