Hello!
I am trying to compile multiple stylesheets at web-appserver-startup. I
have tried a couple of ways.
-------------------------------------
First way
-------------------------------------
The most simple sets the URL to an XSL resource and then sends it to:
public void newTransformer(URL xsl) {
XSLTC xsltc = new XSLTC();
xsltc.init();
xsltc.compile(xsl);
}
Doing this causes an Error in the compilation of the Init Servlet [Error 1 -
below]. I have the jaxp.properties file with the following entries:
javax.xml.transform.TransformerFactory=org.apache.xalan.xsltc.runtime.Transf
ormerFactoryImpl
javax.xml.parsers.DocumentBuilderFactory=javax.xml.parsers.DocumentBuilderFa
ctory
javax.xml.parsers.SAXParserFactory=javax.xml.parsers.SAXParserFactory
-------------------------------------
Second way
-------------------------------------
If I try another way to compile the XSL, the System output says the
...xsltc.TransletTemplate@xxxxxs were created:
public void newTransformer(String id, URL xsl) {
File xslt_file = new File(xsl);
long xsl_last_mod = xslt_file.lastModified();
// CONTEXT = global ServletContext var - basically a Hashtable
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);
// global ServletContext var - basically a Hashtable
CONTEXT.setAttribute(id, templates);
}
}
When I try to access the compiled XSL with the method directly below I get a
different error sent to the browser (500). They seem to be the same error
[Error 2 - below].
public void doTransform(String source_uri,
Templates style,
Hashtable params,
PrintWriter out)
throws FileNotFoundException, TransformerException {
try {
Transformer transformer = style.newTransformer();
transformer.transform ((Source) new InputSource(source_uri),
new StreamResult(out));
} catch (Exception e) {
out.write(e.getMessage());
e.printStackTrace(out);
}
}
----------------------------------------------
Please help. I don't understand what I am doing wrong.
Thanks!
