how to validate a xml file with schemas via SAX

[oregon]

I want to validate XML documents with schemas via SAX
I have problems when asigning an *.xsd file to *.xml document

My code:

<p:user xmlns:p="http://www.google.com"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.wsf.net user.xsd">

It works in my computer but don't in others.
The SAX parser fails to recognize that user.xsd is located in the same folder as XMl document.

So I decided to assign the schema document programmatically:

static final String = JAXP_SCHEMA_SOURCE =
"http://java.sun.com/xml/jaxp/properties/schemaSource";
theParser.setProperty(JAXP_SCHEMA_SOURCE, new File(...some *.xsd file full path));

But this has thrown NotRecognizedException.

any ideas?
thanks

I don't think that the standard SAX parser can validate a file against a schema. They can using DTD's but, I do not think against schemas. You can use the MSV project to validate your documents though. I use it a lot in unit tests for XML validation.

Validating XML with the schema is a very arduous task that is not for the faint of project. SAX can validate against DTD's because DTD's are simple. Schemas are complex creatures that are not to be trifled with. That is why there exists the MSV project.
