Redirect-Extension

[Holger Ebert <ho...@media-engineering.de>]

I am using the redirect extension to generate multiple Html-Files from
one Xml-File. When starting Xalan from the commandline with

    java -cp xalan.jar;xerces.jar;bsf.jar;bsfengine.jar
org.apache.xalan.xslt.Process -in test.xml -xsl generate.xsl -out
generate.html

everything works fine.

I want to use this within an application, when starting with

    processor = XSLTProcessorFactory.getProcessor();

    // Create the 3 objects the XSLTProcessor needs to perform the
transformation.
    XSLTInputSource   xmlSource = new XSLTInputSource("test.xml");
    XSLTInputSource   xslSheet = new XSLTInputSource("generate.xls");
    XSLTResultTarget  xmlResult = new XSLTResultTarget("generate.html");

    // Perform the transformation.
    processor.process(xmlSource, xslSheet, xmlResult);

i got the following exceptions

    Call to extension function failed: method call/new failed:
java.lang.reflect.InvocationTargetException target     exception:
java.lang.RuntimeException: Function not supported!

All of the files are generated but they are empty.

Any suggestions?

May be you will see what happend when you look at the stacktrace of
the embedded exception. The following method often returns some
usefull information:

  public String info(Throwable t)
  {
    StringWriter buf = new StringWriter();
    PrintWriter out = new PrintWriter(buf);
    for (int i = 0; i < 10 && t != null; i++ ) 
    {
	if ( t instanceof java.lang.reflect.InvocationTargetException )
	{
	    t = ((java.lang.reflect.InvocationTargetException)t).getTargetException();
	}
	if ( t instanceof org.xml.sax.SAXParseException )
	{
	    String uri = ((org.xml.sax.SAXParseException)t).getSystemId();
	    out.println("URL:    " + uri);
	    out.println("Line:   " + ((org.xml.sax.SAXParseException)t).getLineNumber());
	    out.println("Column: " + ((org.xml.sax.SAXParseException)t).getColumnNumber());
	}
	t.printStackTrace(out);
	if ( t instanceof org.xml.sax.SAXException )
	{
	    t = ((org.xml.sax.SAXException)t).getException();
	}
	else
	{
	    t = null;
	}
    }
    return buf.toString();
  }

Hope it helps, edwin
