Hi Gary,

If you look in the scratchpad area of the source
(src\scratchpad\webapp\samples\castor) there is an example of how to do a
Castor transformation.

Subject: Castor and Cocoon


I have a Java object that I am trying to turn into XML in my custom
generator class.  I am trying to use Castor to do this.  I am not sure how
to integrate Castor into the generator class.  My concern is how I set the
ContentHandler.  Does anyone have any input.  There was not much on the web
about this.

Thanks,
Gary

Custom generator:

public void generate() throws SAXException, IOException
    {
      try
      {
        ClaimActivity claim = new ClaimActivity();
        claim.setInsuredName("Joe Shmoe");

        // the org.xml.sax.ContentHandler is inherited
        // through org.apache.cocoon.xml.AbstractXMLProducer
        Marshaller.marshal(new ClaimActivity(), contentHandler);
      }
      catch (ValidationException valex)
      {
        valex.printStackTrace();
      }
      catch (MarshalException marex)
      {
        marex.printStackTrace();
      }
    }


Her is the error that I am getting:
