XML-XSD schema location strategies do break on Windows
------------------------------------------------------
Key: GEOT-1635
URL: http://jira.codehaus.org/browse/GEOT-1635
Project: GeoTools
Issue Type: Bug
Components: core xml
Affects Versions: 2.5-M0
Reporter: Andrea Aime
Priority: Critical
Trying to unit test wcs 1.1.1 xml readers I've stumbled on what looks like unix
specific behaviour or assumptions.
If you try to run, on gs trunk, communit/wcs111, the
GetCapabilitiesTest.tstPostBasic() test, you'll be greeted by the following
error message (on Windows, on linux I don't know):
{code}

{code}
Little debugging shows the issue is probably in Schemas.parse(String location,
List locators, List resolvers),
where the is code looking like
{code}
if (new File(location).exists()) {
location = new File(location).getCanonicalFile().toURI().toString();
//location = new File(location).getCanonicalPath();
}
{code}
the location in my case is
file:/C:/progetti/geoserver/src/trunkClean/geoserver/community/wcs111/target/classes/org/geoserver/wcs/xml/v1_1_1/wcsAll.xsd
and the
test fails, possibly because there is the hard disk unit in the middle.
The following test:
{code}
public static void main(String[] args) throws Exception {
final String path =
"file:/C:/progetti/geoserver/src/trunkClean/geoserver/community/wcs111/target/classes/org/geoserver/wcs/xml/v1_1_1/wcsAll.xsd";
if(new File(path).exists())
System.out.println("Found as file");
if(new File(new URI(path)).exists())
System.out.println("Found as uri -> file");
}
{code}
shows that only the second if succeeds.
This is not the firt time I've been hit by the assumpiton that URI and File are
interchangeable in the xml-xsd code... this may work on unix but
it breaks on windows.
Moving to some thing else while I'm waiting for the fix.
