Using TRaX + XSLTC, getting TransformerConfigurationException

[Bruce E. Sturgen]

Basically, I copied the JAXPTransletMultipleTransformations code from 
the Xalan samples. When loading the XSL and creating the Templates 
object, everything is fine, but when I attempt to create a Transformer 
from the Templates instance, I receive a 
TransformerConfigurationException. The same XSL works fine when I do not 
use the xsltc.trax.TransformerFactoryImpl as the default 
TransformerFactory.

I looked at the code, and am confused by what could be going wrong. I 
tried compiling the XSL from the command line, and the appropriate class 
was generated. All of the xalan/bin/*.jar files are placed in my WEB-
INF/lib directory within my WAR file. Could it be that the 
TransletClassLoader does not work within the context of a WAR file? Or 
am I doing something fundamentally wrong here.

TIA for any clues.

In my class constructor I am doing:

     final String xsltcTransformerClass = 
"org.apache.xalan.xsltc.trax.TransformerFactoryImpl";

     try {
       Class.forName(xsltcTransformerClass);
     }
     catch (Exception e) {
       
Category.getInstance("org.titanomachia.servlet.view").error("Problem 
loading " +
         xsltcTransformerClass, e);
       throw new ServletException(e.getMessage());
     }

     java.util.Properties p = System.getProperties();
     p.put("javax.xml.transform.TransformerFactory", 
xsltcTransformerClass);
     System.setProperties(p);

     try {
       TransformerFactory factory = TransformerFactory.newInstance();
       templates = factory.newTemplates(new StreamSource(xslURI));
     }
     catch (Exception e) {
       Category.getInstance("org.titanomachia.servlet.view").error(
         "Problems constructing Translet from XSL file, attempt to use 
interpretive mode.", e);
       throw new ServletException(e.getMessage());
     }

And later, I am doing:

     try {
       Transformer t = templates.newTransformer();
       t.transform(new DOMSource(view),
                   new StreamResult(response.getOutputStream()));
     }
     catch (TransformerException te) {
       Category.getInstance("org.titanomachia.servlet.view").error(
         "Error transforming XML document.", te);
       throw new ServletException(te.getMessage());
     }

I received the following exception:

2001-08-22 14:42:42,063: org.titanomachia.servlet.view ERROR
