XML signature format issue in request?

[pacow]

I'm having trouble getting my signature verified by the host server
(who is remote and uses ibm software), in my code i call:

  FileOutputStream f = new FileOutputStream(fileName);
  f.write(requestMessage.getSOAPPartAsBytes());
  f.flush();

to observe the request as it is sent, one curious thing i note
is that the signature is broken up, and displayed over three lines:

<ds:SignatureValue>
STnDSvXfwg5DupPnQOK2JR5yLYSTn32FPM5c7T4YlFxZZUBtU44QY2rkhXMXZqXW+vnMinY5Tfcs
TLrgbscpDTb4jRhDuvlKKIvgY1W3wURpPuvuSVFwjBqUOjiZJL/gxOsgUMLZFLitzdn4u8/zbwfn
I2JQWSVU5LSNa+7T+ek=
</ds:SignatureValue>

is this a problem? shouldn't it be like this:

<ds:SignatureValue>STnDSvXfwg5DupPnQOK2JR5yLYSTn32FPM5c7T4YlFxZZUBtU44QY2rkhXMXZqXW+vnMinY5TfcsTLrgbscpDTb4jRhDuvlKKIvgY1W3wURpPuvuSVFwjBqUOjiZJL/gxOsgUMLZFLitzdn4u8/zbwfnI2JQWSVU5LSNa+7T+ek=</ds:SignatureValue>

?

thanks,
