I have an xml that is about 580k and I can transform it into an html with an xsl with xalan at my command line. It takes about 5 seconds. This is my command line statement:
java org.apache.xalan.xslt.Process -in xml.xml -xsl xsl.xsl -out output.html
When I move this process to a servlet, I am getting about 25 seconds to transform the same xml into the same html. Here is a snippet from my servlet.
//sets up the xml file to transform
File xmlFile = new File(xml.xml);
//sets up the xsl file to do the transforming
File xsltFile = new File(xsl.xsl);
Source xmlSource = new StreamSource(xmlFile);
Source xsltSource = new StreamSource(xsltFile);
TransformerFactory transFact = TransformerFactory.newInstance();
Transformer trans = transFact.newTransformer(xsltSource);
PrintWriter pw = new PrintWriter(new FileOutputStream(htmlFile));
trans.transform(xmlSource, new StreamResult(pw));
I am using a number of keys in the xsl and I reference another xml file with the document() xsl function in xsl.xsl. Could this be the cause of my delay? Is there anyway to track what's happening in the xsl transformation when it is in a servlet?
is there anyway to find out how a transformation at the command line would take less than a transformation in a servlet. I see no errors in my console when the servlet is transforming.
thanks for any help you can provide.
