The 2N2222 is fine, but the J176 is a p-channel JFET and not what you want (it will be 'on' all the time in this circuit- until you turn the 2N2222 on, after which it and the 2N2222 will both be fried). 

Try a BSS84 for the p-channel MOSFET, or maybe a BS250 if you insist on using bulky through-hole parts. 

The datasheet for the J176 is a little remiss in not telling you exactly what it is or using a schematic symbol anywhere at all.
