Re: [eclipselink-users] MalformedURLException in sdo-compiler
David,

I understand that - I was explaining that the behavior wasn't bizarre or incorrect, but expected with your configuration.  Regarding your current issue, the error typically indicates that there is an IDREF somewhere that references an element that does not have an ID element.  I don't know if this is the case here, but worth checking out.  If not, perhaps you can provide a simplified test case - one or two schemas with as few types/elements as possible in order to recreate the issue.

The problem here is that your base location is set to the xsd/maindoc
directory, which means every schema location is resolved against it,
unless absolute.  So the import in UBL-Common... is being resolved
against the xsd/maindoc directory (as it should).  You would need to
write your resolver to handle this, for example:
    ...
    if (schemaLocation.startsWith("../")) {

setBaseSchemaLocation("file:///C:/EclipseLink/eclipse-main/sdo/bin/xsd/main
doc/"); } else {

setBaseSchemaLocation("file:///C:/EclipseLink/eclipse-main/sdo/bin/xsd/comm
on/"); }
    // resolve accordingly
    ...

So I then get another problem.

Exception Description: Could not find ID element of type ID on type with

CodeType does not have a type ID, nor an element ID as far as I can see.
Any idea why it might be looking for one?

The Schemas can be downloaded from:-

http://docs.oasis-open.org/ubl/os-UBL-2.0.zip

In the xsd directory you will find the UBL-Invoice-2.0.xsd that I was
trying to load.

I am running on Linux, so I set the base location to:-

  setBaseSchemaLocation(System.getProperty("user.dir"));

I did also try adding in a "/" on the end just in case.

in the CustomClassGenerator just before I call:-

  Source source = super.resolveSchema(sourceXSD, namespace,
schemaLocation);

That is to say how do I do this using the command
sdo-compiler.sh?

Also why does the else below (and that in the default one) use
new URL when surely it should use new URI?

Hey David,

To handle this scenario you will need to implement a
SchemaResolver (org.eclipse.persistence.sdo.helper package)
that can load the doc based on the relative path.  To do this,
you can simply extend the default resolver we provide
(org.eclipse.persistence.sdo.helper.DefaultSchemaResolver) and
override the resolveSchema(Source, String, String) method to
handle this case. Note that the schema resolver is passed in as
a parameter in the define method on the delegator.

Here's an example of a custom resolver:

    public class CyclicSchemaResolver extends
DefaultSchemaResolver { public Source resolveSchema(Source
sourceXSD, String namespace, String schemaLocation) {
            if (schemaLocation != null &&
!schemaLocation.equals("")) { return
super.resolveSchema(sourceXSD, namespace, schemaLocation); }
            schemaLocation = namespace.equals("uri") ?
"Cyclic1.xsd"

: "Cyclic2.xsd";

            URL schemaUrl = null;
            try {
                if (getBaseSchemaLocation() != null) {
                    // Attempt to resolve the schema location
against the base location
                    URI baseUri = new
URI(getBaseSchemaLocation()); URI resolvedUri =
baseUri.resolve(schemaLocation); schemaUrl =
resolvedUri.toURL(); } else {
                    schemaUrl = new URL(schemaLocation);
                }
            } catch (Exception e) {
                return null;
            }
            return new
StreamSource(schemaUrl.toExternalForm()); }
    }

Please let me know if you have any questions.

I am trying to run the sdo-compiler against some of the OASIS

resolving schemas.

This is using 1.0M11.

Looking at the relevant line in the xsd file, it starts:-

<?xml version="1.0" encoding="UTF-8"?>
<!--

and I think it is complaining about schemaLocation.

I guess this is because of the lack of a protocol.

I am using Sun Java 6 on linux, using its default XML code.

Perhaps the code in DefaultSchemaResolver needs to trap this
exception and try adding file:/// to the front of the URL.  I
do not know whether this is really a fault with the OASIS xsd
file but they have been in the field for a while and I am sure
of XML parsers generally objected to this it would have been
picked up as a problem.

In fact looking at the code, should DefaultSchemaResolver.java
line 55 which currently reads:-

                schemaUrl = new URL(schemaLocation);

read instead:-

		schemaUrl = new URI(schemaLocation).toUrl();

as the javadoc for URI says that it can handle this kind of
specification without a protocol.
