Finding multiple roots with one input

Hello, guys.

Is there simple ways to get multiple roots using FindRoot or Solve command ? To get one solution with a given range of x is ok. But I couldn't find the way for multiple roots.

For example, in following equation... Solve[SphericalBesselJ[1, x] == 0, x]

Could you help me ? Thank you in advance.

You can give an interval where to look for roots:

Solve[SphericalBesselJ[1, x] == 0 && -1 <= x <= 10, x]

On my system Solve misses the x=0 solution, but it finds two nonzero solutions.
