Looks like you have sdo-api jar in ClassPath, what about sdo-impl jar?

Hi,
here is my test client code
//Create a DataGraph
//SDOUtil.createTypeHelper();
DataObjectUtil.initRuntime();
URL url = thisClass.getResource("/newEMF.xsd");
InputStream inputStream = url.openStream();
//HelperProviderImpl helperProvider = new
HelperProviderImpl();
XSDHelper.INSTANCE.define(inputStream,
url.toString());
inputStream.close();
DataGraphImpl datagraph = (DataGraphImpl)SDOUtil.
createDataGraph();
datagraph.createRootObject(
"http://www.ibm.com/websphere/fvt/ejbquery/emf","DataGraphRoot";);
XSDHelper.INSTANCE invocation gives the following stack trace
Caused by: java.lang.NullPointerException
at commonj.sdo.impl.HelperProvider.getXSDHelper(
HelperProvider.java:343)

I tried to put the HelperProviderImpl class name in the
META-INF/services/commonj.sdo.impl.HelperProviderImpl text file in the
src.main.resources package.But looks like it is not picking up the name
for the HelperProviderImpl.
Here is the xsd file
