FOP在与JAXB一起使用时无法使用数据

我使用FOP（0.95）通过传递使用JAXB（2.2.13）创建的源XML文件来生成文档，当我运行它时，我得到一个几乎为空的PDF（它看起来，如果没有数据源XML提供的，我期望）和唯一的日志输出是：FOP在与JAXB一起使用时无法使用数据

DEBUG [FOP] target-resolution set to: 72.0dpi (px2mm=0.35277778) 
INFO [org.apache.fop.layoutmgr.table.TableLayoutManager] table-layout="fixed" and width="auto", but auto-layout not supported => assuming width="100%" 
WARN [org.apache.fop.layoutmgr.PageBreakingAlgorithm] Part/page 0 overflows the available area in block-progression dimension. (fo:static-content, no context info available)

但如果我注释掉包信息行

@javax.xml.bind.annotation.XmlSchema(namespace = "http://www.blah.com/ctms/Comparison")

。 java文件从JAXB从我的XSD生成并重新编译，然后PDF生成罚款。

是否有一个明显的变化，我需要使我可以使用生成的JAXB代码而不编辑任何东西，或者一些调试我可以启用以查看发生了什么？

我的XSD是：

（我对上述文件进行的唯一修改是“嗒嗒”来代替我的作品的名字）

更新我也试图在XSD设置elementFormDefault="qualified"，但没有帮助（虽然生成的XML确实丢失了“ns2”命名空间前缀）

如何创建XSL-FO？一些XSLT转换？看起来像这个转换期望文档在默认名称空间中。

如果是这样，那么有两种方法来计算策略是：

如果你想保持XSLT，因为它是你必须改变模式是namespaceless。
如果您可以更改XSLT，则使其处理名称空间中的元素而不是空名称空间。使用elementFormDefault="qualified"和attributeFormDefault="unqualified"，这是通常的做法。

决定主要基于这个问题 - 如果你关心你的模式的命名空间。如果你不这样做，第一种方法将花费你更少的努力。我个人而言，我会选择第二个选项，我认为命名空间很重要。

还有一种方法是保留名称空间，但在使用FOP进行渲染之前使用XSLT删除它们。

是的，代码使用XSLT，我很乐意改变它。我会尝试第二种方法。 –

不幸的是，第二种方法并不适合我。最后，我最终删除了命名空间，主要是因为我处于截止日期，而这纯粹是应用程序内部的，所以缺少命名空间并不重要。谢谢 –
