Libarary xades4j . code as following:
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);
if there is not any namespace defined in XML document and the getxPath() return path likes
"/Document/component" ,
the both the signature generation and verification work well .
and then , I add the namespace into the xml file :
<Document xmlns="ff:kk">
and change the return value of getxPath() to
"/ff:kk:Document/ff:kk:component"
Exceptions are threw out when signature generation
Prefix must resolve to a namespace: ff:kk
it seems that i have to add something like xpath.setNamespaceContext(javax.xml.namespace.NamespaceContext) into the code during signature generation.
but where can I do it .
thanks
exception stack as below

回答1:
On the namespace declaration you're stating that de default namespace for that element is "ff:kk", not the prefix. On the xpath expression you're using it as a prefix, which is not defined.
You probably want something like xmlns:prefix="namespace" on the top element and then /prefix:Document/prefix:component on the xpath.
