Attached signed xml message to send to TP, which document type should be used

Aamir

Dear All

We are using java call out to sign xml message and send to TP, please note that this message is not Base64 encoded,

We have doubt that signed message got changed when we send this message through binary/flat document to TP.

Because I am saving message to a file before sending to TP from callout and its verifiable with CMS package but Wire message got changed and not being verified.

Its full doubt that message is changed.

Can any body suggest us what should the issue, which document we should use.

following is callout java code
