[jira] Commented: (TUSCANY-358) TypeHelper.getType(Class ...)
either returns unexpected Type or throws ClassCastException for java
.lang.String or other simple java types
[ http://issues.apache.org/jira/browse/TUSCANY-358?page=comments#action_12379129 ]
Frank Budinsky commented on TUSCANY-358:
----------------------------------------
1) you shouldn't be touching XMLTypePackage or any other EMF things directly. If you stick to the SDO API, this can't happen.
2) This is not well defined in the spec, but I added support to return the most appropriate "commonj.sdo" built-in type for the simple Java types - according to the tables on pg.69-71 of the spec.
I'll commit the change as soon as svn.apache.org is up again.

> Key: TUSCANY-358
> URL: http://issues.apache.org/jira/browse/TUSCANY-358
> Project: Tuscany
> Type: Bug
> Components: Java SDO Implementation
> Versions: Java-M1-tentative
> Reporter: Raymond Feng
> Assignee: Frank Budinsky
> Priority: Critical
> Fix For: Java-M1-tentative
>
> I ran into two problems:
> 1) If I happens to initialize EMF XMLTypePackage, TypeHelper.getType(String.class) throws a ClassCastException
> java.lang.ClassCastException: org.eclipse.emf.ecore.impl.EDataTypeImpl incompatible with commonj.sdo.Type
> at org.apache.tuscany.sdo.helper.TypeHelperImpl.getType(TypeHelperImpl.java:92)
> 2) Otherwise
> I received org.apache.tuscany.sdo.impl.DataTypeImpl@67026702 (name: LangType) (instanceClassName: java.lang.String) (serializable: true)
> and the EPackage is:
> org.eclipse.emf.ecore.xml.namespace.impl.XMLNamespacePackageImpl@13d813d8 (name: namespace) (nsURI: http://www.w3.org/XML/1998/namespace, nsPrefix: xml)
> It seems that the SDO spec doesn't well define the behavior.
