编译架构时出现异常
我们正在尝试解析 XSD 并从中构建属性表（使用 XML Bean）。
代码如下：
XmlObject xmlObj = XmlObject.Factory.parse( schema );
sts = XmlBeans.compileXsd(new XmlObject[] { xmlObj }, XmlBeans.getBuiltinTypeSystem(), null);
调用compileXsd 抛出异常并显示消息： 第 0 个提供的输入不是架构文档：其类型为 N=
我们的架构如下所示：
<schema xmlns:com.co.workflow="com.co.workflow" xmlns:org.data="org.data" targetNamespace="org.activity" version="1.0">
<complexType class="org.activity.ExecuteCommand" name="executeCommand">
<complexContent>
...
...

We're trying to parse an XSD and build a property sheet out of that (using XML Beans).
The code is as following:
XmlObject xmlObj = XmlObject.Factory.parse( schema );
sts = XmlBeans.compileXsd(new XmlObject[] { xmlObj }, XmlBeans.getBuiltinTypeSystem(), null);
Call to compileXsd throws the an exception with message: The 0th supplied input is not a schema document: its type is N=
Our schema looks like this:
<schema xmlns:com.co.workflow="com.co.workflow" xmlns:org.data="org.data" targetNamespace="org.activity" version="1.0">
<complexType class="org.activity.ExecuteCommand" name="executeCommand">
<complexContent>

我在某处读到传递给 XmlBeans.compileXsd 的对象需要是 SchemaDocument 的实例。所以试试这个：
SchemaDocument.Factory.parse而不是XmlObject.Factory.parseI read somewhere that the object passed to XmlBeans.compileXsd needs to be an Instance of SchemmaDocument. So try this:
SchemaDocument.Factory.parseinstead ofXmlObject.Factory.parse
