Then yes, you can reuse it - but you should be aware that it's not very
optimized doing xml generation through string.  If you're doing short
documents, you may not notice any issue.  But if you have a larger
document
you may wish to reimplement in SAX.  Try it first as is - you may be
perfectly satisfied.

The short answer about how is basically:
1) Make sure you read up on Generators, including the tutorial on
CustomGenerators if you haven't already.  Also read up on Avalon (the
stuff
at in the Cocoon docs should be enough).
2) Create a generator that imports your original class, and populate a
String in your Generator by calling appropriate methods in your class.
Exactly how is 100% determined by the specifics of how it works now, but
I
trust you can figure that part out.

I have to gloss over the next details I think until I know what version
you're using:
3) Lookup the parser from Cocoon's ComponentManager (which means your
Generator needs to extend ComposerGenerator, or implement Composable
itself).
4) Do InputSource inputSource = new InputSource(new StringReader(
yourXMLString ));
5) Pass that inputSource to parse();

What version of Cocoon are you using? 2.0.3, 2.0.4, or 2.1dev?

If you're using 2.1dev, check out WebServiceProxyGenerator (quick before
someone refactors it to not use String anymore).  It does almost exactly
what you want, except it gets the String over HTTP from any arbitrary
url.
In fact, you may look into that as a quick option.  Don't know your
current
setup, but if you can call the servlet and get xml string back via HTTP
you
could be finished quite quickly.

HTH,
Geoff Howard

 This all depends on what you were doing in your class.  Were you
 creating
 xml?  If so, DOM, SAX or String?

  My goal is to move from current servlet based solution to Cocoon.
The

  1) Take the request,

  3) Use XSLT to generate html which is returned...

  Can I do that?

Yes you can do a generator :

Here is what I did, this is a main structure :



import your_package;


public class your_class extends ComposerGenerator (or
absctractGenerator)
{
...

 public void setup(SourceResolver resolver, Map objectModel, String 
src, Parameters par)
 throws ProcessingException, SAXException, IOException
 {
 super.setup(resolver, objectModel, src, par);
}

 public void recycle()
 {
}

 public void generate() throws SAXException, IOException, 
ProcessingException
 {
/*  to generate sax events  */
}

for exemple:
 public void your_method throws IOException, SAXException, 
ProcessingException
 {
}
