Hello,
Thanks Ant Elder, your Apache Tuscany SCA Java 1.5 released
announce mail responded my last question on this list.
Raymond, the problem was fixed in version tuscany 1.5. I
didn't need comment the service promotion.
I have had the same exception when I tried something like this:
0. public class BiochemicalCircleImpl implements BiochemicalCircle{
1.
2. public Laboratory getLaboratory(String name) {
3. if (name.length() < 5)
4. return null;
5. Laboratory lab = EntityFactory.INSTANCE.createLaboratory();
6. lab.setName("Main Laboratory");
7. return lab;
8. }
9. }
If condition was true in line 3, null was returned an the exception was:
Exception in thread "main" java.lang.ClassCastException:
org.apache.tuscany.sdo.impl.AnyTypeDataObjectImpl
otherwhise, all works perfectly!
My solution was, create a Laboratory object with properties setted in
null and change invocation logic assuming that always will return a
Laboratory object. Empty Laboratories were considered when any of its
properties was null.
Thanks Raymond, and all people who responded to my earlier concerns.
Best Regards,
Sebastián Groh
