[api-dev] Almost there? (Re: [api-dev] "/singletons/com.sun.star.reflection.theTypeDescriptionManager" available in which context ?

[Rony G. Flatscher]

Hi Daniel, I assume a copy-paste bug in your code: the type description manager object does not implement XMultiComponentFactory, it implements e.g. com.sun.star.container.XHierarchicalNameAccess. yes, you were right, thank you very much! Still, while exploring that corner it seems that I am not too successful to a) use "theTypeDescriptionManager.getByHierarchicalName( strClassName )"; e.g. receiving an exception "<com.sun.star.container.NoSuchElementException: com.sun.star.comp.helper.Bootstrap>", if using "com.sun.star.comp.helper.Bootstrap" as the class name. b) using "XTypeDescriptionEnumerationAccess.createTypeDescriptionEnumeration()" yields always an empty "XTypeDescriptionEnumeration". Don't know what I am doing wrong, though. Maybe, if someone could take a look at the following Java code example (one can compile it and run it supplying the port number to connect to on the commandline): ----------------------- cut here ---------------------- import com.sun.star.beans.PropertyValue;
