Training course

I am a programmer/analyst with 10 years of experience in DB management and 4GL programming. I want to learn JBase in combination with T24. I have been desperately trying for days now to locate training courses, online/onsite/offsite/ANYKIND, but other than a couple of companies which do not offer these courses for now, I had no luck. Does anyone have any idea where can one participate such course? Thank you.
