Hello,

First, thank you for your reply.

In the previous mail, I extracted the piece of XML code where the line 43 is. Here is with line numbers:

...other datas...
42: <vt:SignedDataObject Id="signeddata1">
43: <vt:Encapsulated>true</vt:Encapsulated>
44: <vt:MimeType>application/pdf</vt:MimeType>
45: <vt:Name>signeddata-1.pdf</vt:Name>
46: <vt:Size>131323</vt:Size>
47: <vt:DigestAlgAndValue>
48: <ds:DigestMethod Algorithm="1.3.14.3.2.26"></ds:DigestMethod>
49: <ds:DigestValue>KuWqL3YVcSMZeHRov5nE90PZSeY=</ds:DigestValue>
50: </vt:DigestAlgAndValue>
51: </vt:SignedDataObject>
...other datas...

As you can see, the Id attribute is set.

And here is the Java class which modelize the DigestAlgAndValueType XML type:

public class DigestAlgAndValueType {

	@Element(name = "DigestMethod", required = true)
	protected DigestMethodType digestMethod;

	@Element(name = "DigestValue", required = true)
	protected String encodedDigestValue;

	protected byte[] digestValue;

	@Commit
	public void commit() {
		digestValue = Base64.decode(encodedDigestValue);
		encodedDigestValue = null;
	}

	@Persist
	public void prepare() {
		encodedDigestValue = new String(Base64.encode(digestValue));
	}

	@Complete
	public void release() {
		encodedDigestValue = null;
	}

... getters and setters...
}

I don't understand about the DigestAlgAndValueType because it is already used in the XML and the mapping works. Here is the piece of XML file which work and which use DigestAlgAndValueType:

16: <vt:BeforeVerification>
17: <vt:Size>131323</vt:Size>
18: <vt:DigestAlgAndValue>
19: <ds:DigestMethod Algorithm="2.16.840.1.101.3.4.2.1"></ds:DigestMethod>
20: <ds:DigestValue>E8re2OFo7sUq0C78R6ueaC8M56xQjvy97OFU9sgaw1U=</ds:DigestValue>
21: </vt:DigestAlgAndValue>
22: </vt:BeforeVerification>

Look in your XML file at line 43, I think you will see there is no "Id" element, set the @Attribute(name="Id", required=false) this should fix it. Also, without seeing the class DigestAlgAndValueType I cannot tell if it has an @Element matching "DigestMethod", though Ill bet there is no such element. A good option for you might be.
