After having taken a closer look at the code of SAXBuilder.build (which
created the exception when using SAXBuilderDemo), it seems that adding
the file name could be done using the getSystemId method of
org.sax.xml.InputSource and modify the code of
SAXBuilder.build(InputSource) (starting line 227):

throw new JDOMException(e.getMessage(),
                    new JDOMException("Error on line " +
p.getLineNumber() +
                                      " of XML document: " +
p.getMessage()));

by something like:
throw new JDOMException(e.getMessage(),
                    new JDOMException("Error on line " +
p.getLineNumber() +
                                      " of XML document " +
in.getSystemId() + ": " + p.getMessage()));

I guess there are other places where the modification would make sense
too.

What do you think ?

Thanks.

Chris
