Electrical – colpitts oscillator with jFET not working


I decided to build a colpitts oscillator using a jFET (2N3819): jFET colpitts oscillator

It seems to work fine @ http://www.falstad.com/circuit/ but when i try to build this circuit it does not work, any ideas?

Thank you in advance.

Is transistor modeled in the simulator the 2N3819?

Sorry, for the not-too-insightful initial thoughts on your question. By the looks of the data sheet above, the transistor you're using operates on much larger voltages than the one in the simulator.
