> Creation of static SDOs for which classes have been generated from XSD does
> not work as expected.
> In particular, I created a data object for a type which has a statically
> generated class, but unexpectedly
> got back an instance of DynamicDataObjectImpl.
> A trelated error maybe that even when I create the static SDO directly from
> the factory, when I later
> try to return it over an XMI binding, I get a PackageNotFoundException.
> Here are the details:
> I created the types using XSD2JavaGenerator from this XSD:
> <?xml version="1.0" encoding="UTF-8"?>
> <schema xmlns="http://www.w3.org/2001/XMLSchema";
> targetNamespace="http://psp.softwareag.com/catalogBaseType";
> xmlns:catalogBaseType="http://psp.softwareag.com/catalogBaseType";>
> <complexType name="CatalogBaseType">
> <attribute name="id" type="string"></attribute>
> <attribute name="catalogID" type="string"></attribute>
> <attribute name="fileName" type="string"></attribute>
> <attribute name="catalogName" type="string"></attribute>
> <attribute name="catalogStatus" type="string"></attribute>
> <attribute name="supplierID" type="string"></attribute>
> <attribute name="eclassVersion" type="string"></attribute>
> </complexType>
> <element name="catalogBaseType"
> type="catalogBaseType:CatalogBaseType"></element>
> </schema>
> The classes get generated in package com.softwareag.psp.catalog.base.type. I
> generated no interfaces ( I
> ran XSD2JavaGenerator with the following options: -noInterfaces
> -noNotification -noUnsettable -prefix).
> I have called the generated factory CatalogBaseTypeFactory.
> Then in my coding (SCA service implementation) I do the following:
> a) statically register the factory with the default context
> static {
> helperContext = HelperProvider.getDefaultContext();
> CatalogBaseTypeFactory.INSTANCE.register( helperContext );
> }
> b) create a data object from the targetNamespace of the XSD and the type
> name
> DataObject obj = helperContext.getDataFactory().create(
> "http://psp.softwareag.com/catalogBaseType";, "CatalogBaseType");
> Unexpectedly obj is an instance of DynamicDataObjectImpl, where I would have
> expected an instance
> of CatalogBaseType instead.
> When I call the service that returns this SDO using a Java RMI client, I also
> get an exception when trying to
> deserialize the dynamic data object:
> org.eclipse.emf.ecore.resource.Resource$IOWrappedException: Package with uri
> 'http://psp.softwareag.com/catalogBaseType' not found. (http:///temp.xml, 5,
> 24)
> which is caused by an underlying
> org.eclipse.emf.ecore.xmi.PackageNotFoundException.
> (see also my previous post with subject "SDO deserialization error")
> This exception also occurs when I use a SDO of the correct type created with
> a call to the CatalogBaseTypeFactory.

> However, I suppose that the first problem (wrong type of SDO created)
> probably is not connected to SCA,
> because there is no SCA code involved. It doesn't matter for this problem
> what context the SCA runtime
> uses, because I use the default SDO context directly when registering the
> Factory and creating
> the SDO.
> The second problem (the PackageNotFoundException upon deserialization) may
> have to do with SCA,
> because there is a mediating SCA transformer.
> I attach an Eclipse project with the xsd, the generated classes and a test
> case.
> When you start the com.softwareag.DataServiceLauncher with assertions enabled
> (-ea) and then run
> com.softwareag.client.DataServiceRMITest, you will see
> a) the AssertionError in com.softwareag.impl.DataServiceImpl for the SDO with
> unexpected type in test case testGetData()
> b) the Exception on the client side when trying to receive the static SDO in
> test case testGetCatalogData()
