Hi everybody,

I try to render html to pdf using the ITextRenderer[1]. I get an
exception [2] in case an xercesImpl is in the classpath, which is
already known in a different thread:

https://groups.google.com/group/flying-saucer-users/browse_thread/thread/de7cc4c5427791f6/fc76d36c82a8a3a2?lnk=gst&q=xerces#fc76d36c82a8a3a2

What Do I have todo, to get my code running, since it differs alot
from the other example?

Greets and thanks in advance

Stefan

public void toPdf(String html){
final FileOutputStream os = new FileOutputStream("/tmp/
file.pdf");

final ITextRenderer renderer = new ITextRenderer();
renderer.setDocumentFromString(html);

renderer.layout();
renderer.createPDF(os);
os.close();
}

I think probably the most reliable way to work around this in all
cases is to parse the input XML yourself.
