Problems setting the external schema Location feature
Hi,
trying to set the feature on a 2.6.2 SAXParser (validation enabled etc.):
m_parser.setErrorHandler(handler);
m_parser
.setProperty(
"http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation",
"/home/peter/metro/svn/development/main/metro/composition/test/file:/home/peter/.dpml/main/dpml/test/jars/dpml-test-testschema.jar!/net/dpml/test/testschema/ConfigurableB.xschema" );
m_parser.parse( new InputSource( new ByteArrayInputStream( xml
.getBytes() ) ) );
with a path to the schema that sits inside a .jar file
it seems that the schema is not found, since I get an error saying that the
root element cannot be found:
org.xml.sax.SAXParseException: cvc-elt.1: Cannot find the declaration of
element 'configuration'.
What kind of schema location is supported by the feature?
Thanks for help

Of course, that assumes the parser already has a
noNamespaceSchemaLocation to start with, i.e., specified in the
document. Then you can use an EntityResolver to actually load another
resource.

You should use the setEntityResolver() method on your SAXParser object
and point it to a class that implements org.xml.sax.EntityResolver.
There's one method, resolveEntity() that you must define. One of the
arguments to that method (systemID I think) will contain the schema
location. Then, just return an InputSource object that points to the
class resource you're trying to load.

Thank for the fast reply!
Thinking about it, would it be possible to set the schema like the main file
via an InputSource and InputStream instead of an URI? That would be perfect
for my needs, since I get the schema via the Classloader.getResource.

What you have specified as an argument is pretty clearly not a URI. It
doesn't begin with a scheme. It's hard to tell from reading it what the
correct URL should be, but the form must be:
jar:file:/path-to-jar-file!/path-within-jar-file
Just guessing, yours would be:
jar:file:/home/peter/.dpml/main/dpml/test/jars/dpml-test-testschema.jar!/net/dpml/test/testschema/ConfigurableB.xschema
What did you think the
/home/peter/metro/svn/development/main/metro/composition/test/
at the beginning would accomplish?
