cdata problem with axis

[Balet Roberto]

hello
 
when i want send a xml with axis i have a convert problem:
for example:
 
<offer><!CDATA[this <is> a problem]]></offer>
will be send
<offer>&lt;!CDATA[this &lt;is&gt a problem]]&gt;</offer>
 
what must i do to avoid this convertion?
when axis do that without cdata ok, but with cdata it must not!
 
anyone can help?
 
thanks
