Hello,
after testing again i noticed, that i do the call to
XSLTInputHandler with the parameters wrong, now
i do the same code with
XSLTInputHandler input = new XSLTInputHandler(xmlSource, xslSource);
and get the a fatal error by rendering: [Fatal Error] :1:1: Premature end of
file.

Does your browser open a PDF viewer?
No!
Do you get error messages? Which messages? Yes, please see below.
Can you download the expected content using a command line tool?
Yes i can perform the operation with saving the xml-source as file and then
transform over fop.bat by command line.
I have log all the steps in Tomcat 4.2.9, i am using java 1.4.
Here it goes:
2004-09-08 10:36:10 START of PDF

the sReturnString comes from a java instance as string,
the stylesheet is for testing hardcoded:
String sHost = hoToolSet.getHttpProtocol( c_request ) + "://" +
c_request.getHeader("host");
String sXSL = sHost + "/ho/cfcreports/xsl/cfcreportpdf.xsl";
Because of an exception the call
XSLTInputHandler input = new XSLTInputHandler(xslSource, xmlSource); is not
performed.
The CODE:
<snip>
log("START of PDF");
log("actionId == 10");
// Source xslSource = new SAXSource(new InputSource(new
URL(sXSL).openStream()));
// Source xmlSource = new SAXSource(new InputSource(new
StringReader(sReturnString)));
// ByteArrayInputStream xmlin = new
ByteArrayInputStream(xml.getBytes());
//ByteArrayInputStream xslin = new
ByteArrayInputStream(xsl.getBytes());
try {
log("try");
if (logPDF == null)
{
log("if (logPDF == null)");
logPDF = new
ConsoleLogger(ConsoleLogger.LEVEL_INFO);
MessageHandler.setScreenLogger(logPDF);
}
String sHost = hoToolSet.getHttpProtocol(
c_request ) + "://" + c_request.getHeader("host");
String sXSL = sHost +
"/ho/cfcreports/xsl/cfcreportpdf.xsl";
log("sXSL: " + sXSL);
log("sReturnString: " + sReturnString);
InputSource xslSource = new
InputSource(new URL(sXSL).openStream());
InputSource xmlSource = new InputSource (new
StringReader(sReturnString));
log("xslSource: " + xslSource);
log("xmlSource: " + xmlSource);
XSLTInputHandler input = new
XSLTInputHandler(xslSource, xmlSource);
//StreamSource xmlSource = new StreamSource(new
StringReader(sReturnString));
log("actionId == 10 go to renderXML" );
renderXML(input, c_response);
}
catch (Exception e)
{
log("catch (Exception e)" + e);
}
log("END of PDF");

Thanks,

I have no idea. Would you care to describe what you expect,
and what you got instead?
Does your browser open a PDF viewer? Do you get error
messages? Which messages? Can you download the expected
content using a command line tool?
BTW
InputSource xmlSource =
new InputSource(new StringReader(sReturnString));
In 99% of all cases I've seen this kind of code
indicates either a major design flaw or that you are
using the wrong tool to solve your problem.
