Oh - Thanks for clearing this out for me :)
Now my Java method returns a "javax.xml.transform.sax.SAXSource", and I put
this in my logicsheet like this:
------------------
<xsl:template match="pim:controller">
<xsp:logic>
SAXSource msg = Controller.execute();
</xsp:logic>
<xsp:expr>msg</xsp:expr>
</xsl:template>
------------------
But this prints out "javax.xml.transform.sax.SAXSource@7b56e", which looks
like a reference the object. Do you have any idea what I'm doing wrong here?
Best regards
Søren

Emne: RE: SAX tree?
there is no such thing as a SAX tree, if it is a tree it is a DOM tree.
SAX is an interface that generates event streams, like when you parse a xml
file with sax the sax parser would fire events like startDocument(),
startElement(), endElement(), endDocument() in a succession of function
calls.
DOM creates a tree of nodes much like an unbalanced b-tree where every node
represents a element, atrribute and visa versa.
DOM is then again mosty buildt up by a SAX parser, because you could taje
the events from the SAX parser and create the corresponding nodes when the
event functions tells you so.
the javax.xml.transform.sax.SAXSource is junction between thes two ways of
processing xml because a SAXSource could be a stream of
ascii(javax.xml.transform.stream.StreamSource), a stream of SAX events
(javax.xml.transform.sax.SAXSource) or a DOM tree
javax.xml.transform.dom.DOMSource. all of these can be a
javax.xml.transform.Source to create SAX events which is what cocoon2 likes
to eat.
Cocoon2s generators are in general just routines that creates SAX events
from various sources. if you have a Document object in memory, you can pass
it to cocoon2 through "DOMStreamer", a utility class in cocoon2 that
generates SAX events from a DOM source.
to make a long story short, DOM is xml nodes in memory as nodes in a b-tree,
while SAX is just function events that pass by a api and never leaves
anything in memory, SAX leaves the responsability of creating memory objects
if required to the SAX Handler.
hope this helped a bit! :-)

Subject: SAX tree?
This subject is a little offtopic :)
Ok I will try to return a SAX tree to C2 instead of a stream of XML. I found
the following link that talks about this:
http://www.aoindustries.com/docs/cocoon-1.8.2/faqs.html#faq-xspinsertxml
Now I'm not a XML shark, so I could need some help doing this. I guess I
will be using this API to create a SAX tree:
http://java.sun.com/xml/jaxp/dist/1.1/docs/api/, but what object should I
return? What is it excactly C2 accepts as input? Is it a
"javax.xml.transform.sax.SAXSource"?
Please just give a few pointers :)
