I have tried to debug, but without any luck. :( I'm using Eclipse IDE.
This is my call stack:
ElementNode2.getAttributeNS(String, String) line: 409
SignatureAlgorithm.getURI() line: 303
SignatureAlgorithm.<init>(Element, String) line: 124
SignedInfo.<init>(Document, Element, Element) line: 136
XMLSignature.<init>(Document, String, Element, Element) line: 229
TestXSEC.main(String[]) line: 97
This is the only line of code in getURI():
return this._constructionElement.getAttributeNS(null,
Constants._ATT_ALGORITHM);
but when I step into getAttributeNS():
public String getAttributeNS(String namespaceURI, String localName) {
...
}
I can see that namespaceURI have a value of
"http://www.w3.org/2000/09/xmldsig#"; (and it should be null)
Because of this, the code failes to find attribute. I have never seen such a
case... :(
Best regards,
Milan

I don't know for sure, but you should be able to figure out the problem
by inserting some print statements or running your test case thru a
debugger such as jdb or JSwat (you will have to recompile the Apache
XMLSec source with the -g flag though). Also, make sure when you parse
your Document with a DocumentBuilder you set it to be namespace aware
(DocumentBuilderFactory.setNamespaceAware(true)).

As much as I could debug XSEC, "Algorith" attribute was never found for my
<SignatureMethod> element, although it is there. Perhaps this is an issue
with namespaces?
I'm attaching XML file I was using for testing purposes.

Yes, the docSig parameter should be the
SignatureMethod element and not
the Signature element.
Thank you, Sean. The error message a little confused me.
I did as you suggested and now I got this exception in XMLSignature ctor:
org.apache.xml.security.signature.XMLSignatureException: The requested
algorithm does not exist. Original Message was: null
Original Exception was java.lang.NullPointerException

Exception in thread "main"
I'm using this XMLSignature ctor:
XMLSignature(org.w3c.dom.Document doc,
java.lang.String BaseURI,
java.lang.String SignatureMethodURI,
java.lang.String CanonicalizationMethodURI)
I couldn't find any examples using this ctor. I'm trying to sign already
created XML template with <Signature> element in it. Similar to
templateSign.cpp in C++ examples. I'm using XSEC 1.2.1 and JDK 1.4.2.
Am I doing something wrong? Could someone verify that this ctor works OK?
Best regards,
Milan
