Hussayn, in this particular case the explanation is that OXF compares
with Cocoon on a conceptual level, but doesn't actually use any code
from Cocoon. It is a completely separate project based on a different
architecture of XML pipelines. To tell you the truth, OXF was partly
born from frustrations that its authors had with Cocoon. I hope this
clears up the confusion.

I don't see why this would not be possible (at least in theory) to do
it this way. Usually, from a Struts action you forward your request to
a JSP, but it is actually possible to forward it to any servlet (this
is often how people hook up XSLT with Struts). Such a servlet could be
the Cocoon servlet. You would probably need to have the Struts JAR and
all the Cocoon JARs in the same web application, and to create a
servlet mapping that maps some URLs to the Struts controller. From
Cocoon, you would serialize to XML the JavaBeans put in the request
and session from Struts and from there perform further processing. I
don't know if anybody has attempted this so far though.

Hope this helps,
