Berin, I've attached the following files:
signature1.xml - contains a signature that validates successfully signature2.xml - contains a signature that does NOT validate CreateSignature1.java - class that created signature1.xml CreateSignature2.java - class that created signature2.xml VerifySignature.java - used for verifying the signatures (Set the SIG_TO_VALIDATE variable to 1 or 2 to specify which signature file to verify) Points to note: 1. Both CreateSignature1.java and CreateSignature2.java create an empty SOAP envelope, and insert a simple enveloped signature. The resulting content being signed is identical in each case. The only difference between the two is that CreateSignature1.java uses the DOM api to create the soap envelope, whereas CreateSignature2.java uses the SAAJ api. 2. the files generated by CreateSignature1.java and CreateSignature2.java are identical except for the contents of the SignatureValue element. The DigestValue in each created signature is the same, as I would expect (since the content being signed is the same). 3. It seems that each time I generate a signature, the generated SignatureValue is different, even when the content being signed and the DigestValue does not change. For example, each time I run CreateSignature1.java, the generated SignatureValue is different from last time, even though the content and generated DigestValue remains the same. Is this expected behaviour? Seeing as the signature generated by CreateSignature1.java verifies ok, I presume that this is not necessarily a problem. Thanks very much for your help.
