I know you've asked this for some time, but I found your post just
recently.
Well, I am using JBoss/tomcat (catalina)/cocoon2 also, and I've used a
very simple scheme so far, but it works great, and could be generalized
very easily.
Regarding J2EE, I'm akin to using the fa�ade pattern when it comes to
querying the data, and CMP Beans only when I really need to. That's
because, as you know, CMP Beans use RMI to set/get their values and
that's of course very, very, very, slow. The fa�ade pattern is a session
bean that provides value objects to get access the J2EE-managed data;
there I'm using plain SQL to get things even faster. A fa�ade can also
have some data storing methods, but that's not their main purpose.
Now, the EJB->XML conversion takes place in a logic sheet where I'm
using the standard xsp mechanisms to create the XML, eg:
Data [] myData = facade.getData ( request.getParameter ( "foo" ) );
<data>
<xsp:logic>
for ( int i=0; i < myData.length; i++ ) {
<entry>
<xsp:attribute name="att1"><xsp:expr>myData[i].getAtt1
()</xsp:expr></xsp:attribute>
<xsp:attribute name="att2"><xsp:expr>myData[i].getAtt2
()</xsp:expr></xsp:attribute>
</entry>
}
</xsp:logic>
</data>
In fact, the <xsp:logic> part could be automatized with introspection,
and embedded in the logicsheet with a custom tag (though I've not done
that, I'm pretty sure it's feasible).
The xsp-generated code is very efficient, and this solution has the
advantage of being simple, cocoon-only and rather flexible.
Well anyway, I think this comes all a little too late, doesn't it ?
