Libarary xades4j。代码如下：
static {
try {
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setNamespaceAware(true);
db = dbf.newDocumentBuilder();
} catch (ParserConfigurationException ex) {
// ... ...
}
}
Document doc = db.getNewDocument();
DataObjectDesc obj1 = new DataObjectReference(
"file:///E:/doctosign/forxpath/ori_message.xml")
.withCommitmentType(getCommitmentType())
.withTransform(new CanonicalXMLWithoutComments())
.withTransform(XPath2Filter.intersect(getxPath()))
.withDataObjectTimeStamp( );
XadesSigner xadesSigner = (XadesSigner) new XadesTSigningProfile(keyProvider)
.withTimeStampTokenProvider(TestTimeStampTokenProvider.class)
.withAlgorithmsProviderEx(ExclusiveC14nForTimeStampsAlgorithmsProvider.class)
.newSigner();
xadesSigner.sign(new SignedDataObjects(obj1), doc);
如果XML文档中没有定义任何名称空间，并且getxPath（）返回路径喜欢
“/ Document / component”，
签名生成和验证工作都很顺利。
然后，我将命名空间添加到xml文件中：
<Document xmlns="ff:kk">
并将getxPath（）的返回值更改为
“/ FF：KK：文档/ FF：KK：组分”
签名生成时抛出异常
前缀必须解析为命名空间：ff：kk
似乎我必须在签名生成期间将xpath.setNamespaceContext（javax.xml.namespace.NamespaceContext）添加到代码中。
但我在哪里可以做到。
感谢

答案 0 :(得分：3)
在命名空间声明中，您声明该元素的de default命名空间是“ff：kk”，而不是前缀。在xpath表达式上，您将其用作前缀，但未定义。
您可能需要在顶部元素上使用xmlns:prefix="namespace"，然后在xpath上使用/prefix:Document/prefix:component。
