How can I marshall "portlet.xml"?

[高田 督人 <ma...@exa-corp.co.jp>]

Hi,
I am trying to edit the "portlet.xml" by creating an instance of
"PortletDefinitionImpl" and adding it to the
"PortletApplicationDefinitionImpl" object,
and marshalling the PortletApplicationDefinitionImpl object.
And I have encountered some problems.


When I marshall the "portlet.xml" after unmarshalling the
"portlet.xml"without doing anything to the object,
the Marshallized "portlet.xml" is not same as the original "portlet.xml".
ie: <portlet-info> is lost...

What should I do to not lose <portlet-info>?
