URIConverter question. [message #70848] Fri, 01 December 2006 16:16 Go to next message

Hi,
I am having trouble understanding URIConverter. I have a serialized
(XMI) file from a colleague with the following content (a string
XSDSimpleTypeDefinition):
------------------------------------------------------------ --
<typeDefinition xsi:type="xsd:XSDSimpleTypeDefinition"
href=" jar:file:/D:/Projects/eclipse-projects/frevvo/workspace/com. gauss.forms/lib/org.eclipse.xsd_2.2.0.v200606271057.jar!/cac he/www.w3.org/2001/XMLSchema.xsd#//string;XSDSimpleTypeDefin ition=7 "/>
------------------------------------------------------------ --
As you can see, the href points to a specific file (D:/....). That path
does not exist on my machine making this file non-portable. So,
1) Can I make this portable? I can put the jar file in a common relative
directory (say ../../lib, which will work on all machines for my
application). Can I force the href to point to
jar:file:../../lib/org.eclipse etc.
instead of the D:/Projects?

2) How can I use a URIConverter to affect this? I know what the
URIConverter should do but I am unable to attach my custom URIConverter
to handle this URI. Specifically, MyCustomConverter.normalize(uri) is
never called for this URI even though I have done:
------------------------------------------------------------ --
resourceSet.setURIConverter (new MyCustomConverter());
------------------------------------------------------------ --
Is it that this particular URI is loaded using a Resource from a
different ResourceSet but I don't understand how to affect that.

Thx,
-Ashish

Ashish,

Ouch. That's nasty! The built-in schema for schemas is loaded like
this in XSDSchemaImpl:

public static synchronized XSDSchema getSchemaForSchema(String
namespace)
{
if (XSDConstants.SCHEMA_FOR_SCHEMA_URI_2001.equals(namespace))
{
if (xsdSchemaForSchema2001 == null)
{
try
{
String baseURL = XSDPlugin.INSTANCE.getBaseURL().toString();
getMagicSchemaForSchema(namespace);

getGlobalResourceSet().getLoadOptions().put("XSD_XML_SCHEMA ",
XSDConstants.SCHEMA_FOR_SCHEMA_URI_2001);
getGlobalResourceSet().getResource
(URI.createURI(baseURL +
"cache/www.w3.org/2001/XMLSchema.xsd"), true);

In an Eclipse/OSGi environment this would use
"platform:/plugin/org.eclipse.xsd/" but when running standalone, it will
reference the physical jar location and then the reference will not be
portable. :-(

I've been playing with
https://bugs.eclipse.org/bugs/show_bug.cgi?id=164597 but have not had a
chance to work on it for a while, but that could be used (instead of a
specialization of XMLHelperImpl.deresolve) to turn the non-portable
physical location into a logical URI while saving and then you could use
a URI mapping to ensure that that logical URI maps to the right physical
location. Another wrinkle though is that since this schema for schema
resource is in a separate resource set you'd need to specialize
ResourceSetImpl.delegatedGetResource to look in the special resource set
containing the schema for schemas.

Probably the simplest brute force approach is to specialize
ResourceSetImpl.delegatedGetResource to look for a URI with path
/cache/www.w3.org/2001/XMLSchema.xsd, ignoring the non-portable
authority, and redirect it to return the schema for schemas's resource.

Ashish,

I'm willing to consider making changes in XSD 2.3 that would make life
easier. For example, perhaps the URI of these special resources should
really be their physical location on the web...

As you can see, the href points to a specific file (D:/....). That path
does not exist on my machine making this file non-portable. So,
<br>
1) Can I make this portable? I can put the jar file in a common
relative directory (say ../../lib, which will work on all machines for
my application). Can I force the href to point to
<br>
&nbsp;&nbsp;&nbsp;&nbsp;jar:<a class="moz-txt-link-freetext" href="file:../../lib/org.eclipse">file:../../lib/org.eclipse </a> etc.
<br>
instead of the D:/Projects?
<br>
<br>
2) How can I use a URIConverter to affect this? I know what the
URIConverter should do but I am unable to attach my custom URIConverter
to handle this URI. Specifically, MyCustomConverter.normalize(uri) is
never called for this URI even though I have done:
<br>
------------------------------------------------------------ --
<br>
resourceSet.setURIConverter (new MyCustomConverter());
<br>
------------------------------------------------------------ --
<br>
Is it that this particular URI is loaded using a Resource from a
different ResourceSet but I don't understand how to affect that.
<br>
<br>
Thx,

with it a little bit but I think I understand the gist of what you're

Ashish,

I'm willing to consider making changes in XSD 2.3 that would make life
easier. For example, perhaps the URI of these special resources should
really be their physical location on the web...
