Subject Upgrading 1.8.2 to 2.0.2

Sorry to keep sending this, Outlook keeps insisting on sending HTML


I have looked in the mailing lists, to no avail, please forgive me if these
questions have been answered already.... 
I have upgraded Cocoon 1.8.2 to Cocoon 2.0.2. Here's my setup: 
Cocoon 2.0.2 
Weblogic 6.0sp2 
Solaris 2.6 (Sparc) 
I have successfully installed C2, all the samples work, etc. but I am having
a problem getting my logicsheets to work. I am having 2 separate problems:

Problem 1: Transition from DOM to SAX 
In my logicsheets I have a number of places where I dynamically insert an
XML document, then use the DOM API to access values of specific nodes. I
have come to realize that since C2 uses SAX, I can no longer do this. Here's
an example:

String name = "Joe"; 
NodeList ca = document.getElementsByTagName( "employee" ); 
if ( ca != null ) { 
    Element element = null; 
    String myAttr = ""; 
    int length = ca.getLength(); 
    for (int j = 0; j &lt; length; j++) { 
        element = (Element) ca.item(j); 
        myAttr = element.getAttribute( "name" ); 
        if ( !myAttr.equals( name ) ) continue; 
        myValue = element.getAttribute( "value" ); 
So if I have the following XML fragment: 
<employee name="John" value="23"/> 
<employee name="Jack" value="34"/> 
<employee name="Joe" value="45"/> 
<employee name="Joanne" value="56"/> 
<employee name="Jimmy" value="67"/> 
I want the value "45".  How would I do this with SAX? 
Problem 2: request and response using C2 specific implementation, rather
than javax.servlet.http.HttpRequest and javax.servlet.http.HttpResponse

I use some EJB's which have methods that take the built-in XSP variables
'request' and 'response' as params. It does not work now. Is there a way to
cast org.apache.cocoon.environment.Request as javax.servlet.http.HttpRequest
(and likewise for Response), or is there a better way to do it? I would like
to avoid having to modify the EJBs, which at this point would be a Hurculean

Sorry if these don't seem to be Cocoon 2 questions, but I was thinking maybe
some of you have similar problems. 
Thanks in advance... 
William Bagby.
