No more DTM IDs are available using xalan 2.6.0?

Hi,

I am getting the "No more DTM IDs are available" error during transformation:

javax.xml.transform.TransformerException: org.apache.xml.dtm.DTMException: No more DTM IDs are available
at org.apache.xalan.transformer.TransformerImpl.transformNode(TransformerImpl.java:1226)
at org.apache.xalan.transformer.TransformerImpl.transform(TransformerImpl.java:638)
at org.apache.xalan.transformer.TransformerImpl.transform(TransformerImpl.java:1088)
at org.apache.xalan.transformer.TransformerImpl.transform(TransformerImpl.java:1066)

when using this code:

         TransformerFactory tFactory = TransformerFactory.newInstance();

         // Set the stylesheet stuff
         StringReader srStylesheet = new StringReader(stylesheet);
         StreamSource ssStylesheet = new StreamSource(srStylesheet);
         Transformer transformer = tFactory.newTransformer(ssStylesheet);

         // Set the xml stuff
         StringReader srXmlToConvert = new StringReader(xmlToConvert);
         StreamSource ssXmlToConvert = new StreamSource(srXmlToConvert);

         // Set the resulting HTML
         StringWriter caw = new StringWriter();
         StreamResult dest = new StreamResult(caw);

         // Finally, do the real work
         transformer.transform(ssXmlToConvert, dest);
         html = caw.toString();

      return html;

I am using xalan 2.6.0 (At least I am trying to). So when I run this in my servlet:

out.println("Xalan Version: " + org.apache.xalan.Version.getVersion());

I get:

"Xalan Version: Xalan Java 2.6.0"

This is on windows 2000 server using bea web logic 8.1 and Java 1.4.1.  I know the 1.4.1 java version had old xalan so I (think I) upgraded.  Is my code still pointing to the old stuff?  Any help is appreciated.

Thanks,
Scott
