Hi Sebastien it's not clear to me whether you intend to use lines such as ...
Laboratory lab = EntityFactory.INSTANCE.createLaboratory(); in your solution, or whether this is just a quick piece of demo code. If I understand this thread properly then I think you have solved your problem, however, I would just like to comment that the line ... Laboratory lab = EntityFactory.INSTANCE.createLaboratory(); is not the best way to create an SDO instance. Maybe tyhis is just a quick demo line of code, but using the generated Factory instances directly allows coding that might lead you to believe that you have a good working SDO environment when you might not have. As this thread has mentioned, the SDO runtime needs to have metadat 2009/6/1 Sebastián Groh <[email protected]>: > 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.
