I want to ask if exsist a way in xades4j to made multiple signature.

For multiple signature i mean not countersignature, but a double independent sign to the same document, the resulting signature will have 2 or more signature object. In pratice a signer can take a xml signed document as input and resign it.

In other way i need a method to take as input a xml signed file and get as output the original xml document.

Thanks,

Michele
