Hi Community, I sign a XML message (really, soap message) and then I sent it to the server. The server could validate XML signed, but verification fails (server say that signature is invalid :( ) The strange is if I implement signing line code and validate line in same class, then all works (and signature is valid); I think the problem it is in follow few lines: | DOMValidateContext valContext = new DOMValidateContext(new | KeyValueKeySelector(), signatureTag); | ^^^^^^^^^^^^^^^^^^ | XMLSignature signature = | sigFactory.unmarshalXMLSignature(valContext); | // Validate the XMLSignature (generated above) | boolean isSignatureValid= signature.validate(valContext); | The KeyValueKeySelector is a private static class (within main classes) that extends KeySelectors. It seems on client side method of this class are executed automatically and validate the signature; if I move validation on server side, this class seems not is automatically executed O_o What is the magic of KeySelectors class?? Thanks to all! P.s. Ide: netbeans 5.5 AS: Sun Application Server 9.0 package: XML Signature Api View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3968694#...
