Correct you cannot log it as PIC under JAA. All training is P/UT or Dual.
Also safety pilot doesn't exist in JAA - they call it supernumerary and it doesn't count for anything unfortunately.
Do yourself a favour and do some research into JAR FCL and the search function :

If you are intending UK based then Appendix B of Section A refers Page 44 to be exact regarding logging of flight time in LASORS - Now go read it!
