How to configure TraxProcessor in 2.2?

[Mark H. Wood]

I'm using Cocoon 2.2.  I need to pass a custom XSLT transformer
factory (that wraps Saxon's to configure it) to TraxProcessor, and the
advice I've found in several places around the Web doesn't seem to be
working:  my factory class never gets instantiated.

I've got a file META-INF/cocoon/avalon/cocoon-core-saxon-xslt.xconf:

<?xml version="1.0" encoding="UTF-8"?>
<components>
  <component role="org.apache.excalibur.xml.xslt.XSLTProcessor/saxon"
    class="org.apache.cocoon.components.xslt.TraxProcessor">
    <parameter name="use-store" value="true"/>
    <parameter name="transformer-factory"
               value="org.dspace.saxon.ConfigurableTransformerFactory"/>
  </component>
</components>

I also tried copying it to WEB-INF/cocoon and it didnt' seem to work
there either.

I do have <configurator:settings/> and <avalon:bridge/> in the Spring
config.

Is there some way to debug component configuration and see if the file
is even being looked for (and where *is* configuration looking)?  The
Cocoon site directs me to Excalibur, which directs me to Avalon, which
says that Avalon is wound up and directs me back to Excalibur....



I've also tried to configure the thing using Spring:

    <bean name='org.apache.excalibur.xml.xslt.XSLTProcessor/saxon'
          class='org.apache.cocoon.components.xslt.TraxProcessor'
          init-method='initialize'
          destroy-method='dispose'>
      <!--property name='use-store' value='true'/-->
      <property name='transformerFactory'
                value='org.dspace.saxon.ConfigurableTransformerFactory'/>
    </bean>

but so far I'm missing something:  TraxProcessor.sourceToSAX throws an
NPE.  I'm probably not setting the parameters correctly -- there isn't
a setter for use-store at all, for example.

I've found any number of pages that tell me Avalon configuration is
being replaced by Spring, but nothing practical on how to convert
Avalon configuration (such as the first sample above) to Spring, or
even how to write fresh Spring configuration for Cocoon components.
It would be nice to know how to do this even if I wind up using the
Avalon approach with the present task.
