My Test project has a folder META-INF/services which contains text file commonj.sdo.impl.HelperProvider Also my TuscanySDO project has a folder META-INF/services in (src.main.resources) package.which contains the same text file.
I believe the other way I could try is to set the HelperProvider as a System property.Would you know how I could do this in Eclipse? ritika "Yang ZHONG" <[EMAIL PROTECTED]> 08/18/2006 11:55 AM Please respond to [email protected] To [email protected] cc Subject Re: java.lang.NullPointer exception when invoking XSDHelper.INSTANCE I think it's fine to use sdo-impl project instead of the jar version, as long as META-INF/services/commonj.sdo.impl.HelperProvider is in the same ClassPath/ClassLoader as the sdo-api jar/project. Sometimes people forgets to include src/main/resources which has META-INF/services/commonj.sdo.impl.HelperProvider, is that also your case?
