Use APPLICATION_SCOPE or cast a PortletSession object to HttpSession.

Jacek is absolutely correct.

Set the object in the portlet's session with application scope.  Then,
in your servlet, the object will be available as a standard
HttpSession attribute.

I use this technique all the time...

If you have a HttpSession attribute, there is no difference if it is set 
from a servlet or a portlet. Once it is set, it should be hold in the 
session until the session is invalidated or the attribute is removed. 
What's the problem?

Dear Jacek
   
  At the moment I can't use this approach you suggested 
  because my servlet is not called from my portlet!
   
  Is there any other way ?
   
  tnx alot!

Yes, use:
.getPortletSession().setAttribute(, 
    , PortletSession.APPLICATION_SCOPE);
or:
((HttpSession)
).setAttribute(attrName>,     );

Yes, use:
<RenderRequest>.getPortletSession().setAttribute(<String attrName>, 
<Object attrValue>, PortletSession.APPLICATION_SCOPE);
or:
((HttpSession)<PortletSession yourPortletSession>).setAttribute(<String 
attrName>, <Object attrValue>);
