I suspect you either passed an empty string to the StringReader
for the XML input source, or there is an encoding problem.

RE: !newbie generating pdf from xml-source as stream

2004-09-08 Thread Braumüller, Hans 
Hi Pietschmann,

thanks for your patience, i know it is not easy alwasy answering always the 
same questions. But i have not been luckily with my research, fag, search 
engines, etc.

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

// ByteArrayInputStream xmlin = new 
ByteArrayInputStream(xml.getBytes()); 
//ByteArrayInputStream xslin = new

 try {
log(try);
if (logPDF == null)

log(if (logPDF == null));
logPDF = new 
ConsoleLogger(ConsoleLogger.LEVEL_INFO);
MessageHandler.setScreenLogger(logPDF);
}
String sHost = hoToolSet.getHttpProtocol(

renderXML(input, c_response);

 What is wrong ?

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.

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.
