My mean is It run well,when I used java.security.Signature to verify 
'<root>name</root>'.

Sorry ,I didn't have a clear expression of the question because of my poor 
english. My mean is  whether   <ds:Signature> ..<ds:Signature> included in 
<samp:Assetion ..> ..</samp:Assetion>  will affect the 
SignatureValidator.validate(..).

That looks correct, as far as generating the Credential with which to sign.

Well, if you're sure you are validating with the right key, then it
almost certainly must be the case that the SignedInfo element really has
been modified since it was signed.  You'll need to double-check the
serialization process on the signer side, and the deserialization and
unmarshalling process on the receiving side, to find out where and how. 
That's all I can tell you.

Remember that any change to the signed document will cause the signature
to fail, even something as trivial as addition or removal of whitespace.

I'm not sure what you mean here, what you are validating with the
java.security.Signature?  Or are you saying there seems to be difference
in behavior beween JDK1.5 and some other JDK version?

I'm sorry, I don't understand what you are asking here.  Can you please
rephrase the question?
