I noticed I did not modify the second newTransformer (the one that creates
templates) correctly for the email. THe correct method is (sorry):
public void newTransformer(String id, URL xsl)
throws TransformerConfigurationException {
File xslt_file = new File(xsl.toString());
long xsl_last_mod = xslt_file.lastModified();
Templates entry = (Templates) CONTEXT.getAttribute(id);
if (entry == null) {
Source xsl_source = new StreamSource(xslt_file);
TransformerFactory transfact = TransformerFactory.newInstance();
Templates templates = transfact.newTemplates(xsl_source);
System.out.println(id + " Templates Obj: " + templates);
CONTEXT.setAttribute(id, templates);
}
}
