Bug in parser? 2003-05-27 - By Jon Wilmoth
I've tried simplifying the test by attempting to parse
a document without a dtd reference.
<?xml version="1.0"?>
<test>sample</test>
The java code I use, which still results in an
exception is:
log.debug("TRYING TO PARSE SIMPLE DOCUMENT...");
SAXBuilder builder = new SAXBuilder(false);
builder.setIgnoringElementContentWhitespace(true);
builder.setFeature("http://xml.org/sax/features/validation",
false);
String testDoc = "test.xml";
try {
Document doc =
builder.build(getClass().getResourceAsStream(testDoc));
//I never get here!
log.debug("Successfully parsed test document!");
} catch (JDOMException jdome) {
Throwable root = jdome.getCause();
if (root != null) {
log.error("Root cause:" + root.getMessage());
}
log.error("Failed to parse " + testDoc + " file",
root);
}
