Not sure if I am asking for too much..
I wonder if any of you may have the jInterface.dll (dll created after dcmtk compilation) which wants to share or give me a copy.
Why don't you just download and install the DICOMscope installer, which will install everything you need - the Java binaries, the interface DLL, a working configuration file, manual, conformance statement and so on and so forth. If you want you can then still start exchanging components.
