RE: registering schema locations
Hi,
I looked at the documentation from Sun.
I tried the "http://java.sun.com/xml/jaxp/properties/schemaSource"
property and it works fine. I can register schema locations by reading the
schema files.
sample code :
saxFactory = SAXParserFactory.newInstance();
saxFactory.setNamespaceAware(true);
FileFilter xsdFileFilter = new FileFilter() {
public boolean accept(File pPathName) {
if (pPathName.getName().endsWith(".xsd")) {
return true;
}
return false;
}
};
File[] xsdFiles = xsdDir.listFiles(xsdFileFilter);
saxFactory.setProperty(
"http://java.sun.com/xml/jaxp/properties/schemaSource", xsdFiles);
The problem is that I must do this job each time I need a SAXParser. Is
there any means to use the
"http://java.sun.com/xml/jaxp/properties/schemaSource" property at the
SAXParserFactory level ?
I cannot use always the same SAXParser because I am in a multi-thread
environment and the SAXParser is not required to be thread safe.
Thanks for any help

Thank you, this seems to be a good and simple solution to my problem.
I will try this.

Here is some good documentation from Sun illustrating how to configure it
with JAXP (with Xerces as the parser).

Thank you for the response.
The XML documents I use are generated by JAXB (Sun Java XML Binding
Framework), and JAXB is aware of namespaces, but not aware of schema
locations.
So the XML documents generated do not contain any schema location
information.
If there is no standard way to register schema locations, does Xerces
provide this facility in a proprietary way ?

The W3C's Semantic Web folks are investigating what metadata, if any, is
implied by a namespace and how it should be retrieved and used. Until
they
report out, the official answer is that a namespace URI is only a magic
string in URI syntax. It does not imply a specific schema, and indeed may
be referenced by many schema documents. So for now, even if you can make
this work, it's going to be a unique solution for your own application and
won't work for anyone else.
What's wrong with having the document explicitly declare which schemas it
needs? It has to declare the namespaces, and if anyone knows the mapping
from one to the other it should be no harder to build that into the
document than to try to imply it afterward... and if it's in the document
you avoid having to blaze a path into uncharted and (at least for now)
nonportable terratory.

RE: registering schema locations
Posted by Fr...@filinks.com.
Sorry, my previous message contains sample code that is exposing what I
would like to do with SAXParserFactory.
What I can do until now is :
SAXParser parser = INSTANCE.saxFactory.newSAXParser();
// register namespaces of all xml schema files
File xsdDir = new File(Proprietes.getXSDPath());
FileFilter xsdFileFilter = new FileFilter() {
public boolean accept(File pPathName) {
if (pPathName.getName().endsWith(".xsd")) {
return true;
}
return false;
}
};
File[] xsdFiles = xsdDir.listFiles(xsdFileFilter);
parser.setProperty("http://java.sun.com/xml/jaxp/properties/schemaSource",
xsdFiles);
Is it possible to do this at the SAXParserFacotry level ?
thanks for any help
