axis SAAJ namespace prefix problem
Hi,
I was able to get the whitespace problem solved. I am using Axis 1.1 which does not seem to have this parameter exposed. However I was able to change the axis code which sets pretty xml to false so this problem does not arise anymore and no extra whitespaces inserted in xml.
However, I am having another problem now. Axis when serializing messages, is removing prefix if there is default namespace. For example, if I have the following:
<wsu:Timestamp xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" wsu:Id="TrWh0UdhOBlayXdEr4JbRQ22"><wsu:Created>2005-12-05T22:39:47Z</wsu:Created></wsu:Timestamp>
And if I deserialize and serialize back, Axis gives me:
<Timestamp xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" wsu:Id="TrWh0UdhOBlayXdEr4JbRQ22"><Created>2005-12-05T22:39:47Z</Created></Timestamp>
This is causing problem because we are signing the timestamp element and then the verification is failing since the element has been modified when we remove the prefixes.
Is there any way to turn this off in Axis so Axis does not remove the prefix? Is this bug fixed in newer version of Axis? What are the solutions to solve this problem?

Did you try the following in the global configuration section in Axis 1.1?
<parameter name="disablePrettyXML" value="true"/>
Am not sure if it was even implemented in the old version of Axis.
thanks,
