XMLSignature & serialization/parsing

[Garett]

Hello, I am working on a java project where I use
org.apache.xml.security.signature.XMLSignature to sign an
org.w3c.dom.Document object with an enveloped signature. I then need to
serialize the Document to a String and eventually parse the String back
to an org.w3c.dom.Document object. I can verify the XMLSignature
immediatly after signing, but cannot verify after serialize/parse.

Has anyone successfully done this sort of thing in java?

I am currently using dom4j to serialize/parse. I'm considering trying
jdom.

Does anybody have any suggestions for this sort of thing? Thanks!
