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.
com.sun.star.comp.helper.Bootstrap is an Java UNO helper class and is
not available over the type description manager (tdmgr). The tdmgr
supports only IDL types. And you should take into account that the
normal type library of an office installation doesn't contain type info
for old style service types.
* b) using
"XTypeDescriptionEnumerationAccess.createTypeDescriptionEnumeration()"
yields always an empty "XTypeDescriptionEnumeration".
mmh, that is maybe a bug but i am not sure and have to take a closer
look into the code.

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):
