Bug in parser?
I'm trying to parse a very simple xml document with
xerces 2.4.0. Unfortunately I get the following
error:
java.net.MalformedURLException
at java.net.URL.<init>(URL.java:613)
at java.net.URL.<init>(URL.java:476)
at java.net.URL.<init>(URL.java:425)

The document:
<?xml version="1.0"?>
<!DOCTYPE EventRegistrations SYSTEM
"file:///C:\temp\projects\EventRegistrations.dtd">
<EventRegistrations>
<event name="test.events.BusinessObjectChangeEvent">
<listener>test.ObjectCreationListener</listener>
</event>
</EventRegistrations>
Passes validation in my xml editor. What's going on?

Ah. I thought
getClass().getResourceAsStream("test.xml") delegated
to the
getClass().getClassLoader().getResourceAsStream("test.xml")
and it was the location of the file (i.e.
com/acme/app/text.xml) that specified the package to
look under not the invoking class.

I can tell you exactly why it didn't find
it. getClass().getResourceAsStream("test.xml") looks for the test.xml file
in the same package as your class exists and nowhere else. If you want to
find test.xml in the root of the classpath, then do either
getClass().getResourceAsStream("/test.xml") or
getClass().getClassLoader().getResourceAsStream("test.xml")

Re: Bug in parser?
Posted by Jon Wilmoth <jo...@yahoo.com>.
Thank you that was the issue. Although I'm not sure
why getClass().getResourceAsStream(testDoc); was not
able to find a file that was present in the
/WEB-INF/classes directory! Changing the servlet
initialization code to
context.getResourceAsStream("/WEB-INF/classes/" +
testDoc); worked!
Thanks again,
Jon

Hi Jon,
You might want to check if you're passing in a non-null InputStream. I
believe getResourceAsStream (unless your class was loaded by some custom
ClassLoader), searches the classpath for the resource you want, so if
you've only have jars in your classpath, I doubt it would search in the
file system.

Re: Bug in parser?
Posted by Jon Wilmoth <jo...@yahoo.com>.
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);
}

Hi Jon,
It would be great if you posted a snippet of code before and including
the invocation of SAXBuilder.build, in order to diagnose your problem. It
seems that there is something wrong with the location specified for your
XML file (either an invalid URI, or java.net.URL doesn't recognize the
protocol/scheme of the URI). In either case, Xerces is unable to read
your file.
As a separate issue, I noticed that the system ID that you specified for
your DTD is not a valid URI. It should be
"file:///C:/temp/projects/EventRegistrations.dtd" instead of
"file:///C:\temp\projects\EventRegistrations.dtd" ('\' isn't a valid URI
character). Xerces (by default) will fix up the system ID before it's
used. However, if you want your documents to be portable across different
XML parsers, then you need to make sure that URIs you specify actually
meet the URI spec.
Hope that helps.
