-----------------------------------------
Kelvin, that is correct. Per the directions in the java doc at the top of
ModelFactoryImpl.
> Unable to code gen SDOModel.xsd

> Key: TUSCANY-1457
> URL: https://issues.apache.org/jira/browse/TUSCANY-1457
> Project: Tuscany
> Issue Type: Bug
> Components: Java SDO Tools
> Affects Versions: Java-SDO-M2
> Environment: n/a
> Reporter: David T. Adcox
> Fix For: Java-SDO-1.0
>
>
> When I attempt to generate the java source files representing the SDOModel, I
> am seeing a NPE thrown in SDOXSDEcoreBuilder.java. Here is the stack trace:
> java.lang.NullPointerException
> at
> org.apache.tuscany.sdo.helper.SDOXSDEcoreBuilder.lookupPrefix(SDOXSDEcoreBuilder.java:104)

> I've tracked the issue down to some code changes made for T-513. A change
> was made in XSDHelperImpl in the define method to change how the ResourceSet
> is constructed prior to loading the schema. Additional changes were made in
> SDOXSDEcoreBuilder to set up some options when constructing a ResourceSet.
> These combined changes seem to be precipitating the issue. The
> XSDSchemaAdapterFactoryImpl inner class contains a method
> isFactoryForType(Object) that appears to be setting up conditions such that
> more elementDeclarations than should be expected is being created, later
> leading to the NPE.
